Experiments on Quantum and Classical magnetization reversal process in nanomagnets

In my talk I will report on two different experimental results. First I will comment on the quantum reversal process of the magnetization in molecular magnets mixed with micrometer size superconductor particles. The second topic will be the study

of the classical reversal process of the magnetization in nano size magnetic particles deposited on the surface of a piezoelectric material by surface acoustic waves. In both cases I will provide the theoretical background explaining the observed data.

Raman scattering analysis of thin film chalcogenide solar cells: Methodologies for quantitative assessment of nanolayers and interfaces

Chalcogenide solar cells are receiving an increasing interest because of their potential for the development of cost-efficient devices. This includes technologies that are already at industrial production stage as Cu(In,Ga(S,Se)2 chalcopyrites, as

well as emerging technologies that are in a less mature state as those based in Cu2ZnSn(S,Se)4 kesterites. In these technologies, the typical device structure includes a Mo back contact, the p-type absorber, a n-type nanometric buffer layer (as CdS or Zn(O,S)), an intermediate nanometric layer (i- ZnO or (Zn,Mg)O) and a transparent conductive oxide window. Control of the composition and thickness of the different layers and of the characteristics of their interfaces is relevant for the optimization of the device efficiency. This gives a strong interest to characterization techniques suitable for the high sensitivity assessment of these parameters, if possible in a non-destructive way.

This work reviews the use of Raman scattering based methodologies for these applications. Raman scattering is a non-destructive technique well suited to the analysis of several important material parameters of the different layers in the devices, as the crystalline quality, composition, thickness, presence of secondary interfacial phases and doping concentration in separate layers, as well as complete devices. This includes also the use of resonant Raman strategies for the high sensitivity assessment of nanometric layers and interfacial regions in the device structure. Methodologies suitable for the fast quantitative assessment of the thickness and composition of the layers will be reviewed and discussed, analysing their potential for process monitoring applications in these advanced technologies.

Transport phenomena during inkjet printing of electronic components from colloidal systems

Inkjet printing delivers several advantageous features like flexible writing of patterns, low consumption of ink, the ability to deposit low viscosity liquids and low-costs. Thus, a wide range of electronic and optical components has been manufactured

by inkjet printing of functional inks in the last decade. The present contribution focuses on electronical components. In general, ink represents a colloidal system that consists of both the solvent and the nanosized material. The molecular and atomic properties of the colloidal system are appropriate at lengths of a few nanometers. Wetting properties and kinematics play a significant role at lengths of tens and hundreds of micrometers. Thus, for optimizing the printed pattern the spreading of the ink as well as the redistribution of the solid content inside the placed inkjet droplet must be taken into account. In addition, the dynamics of solvent evaporation and resulting fluid flows impose severe effects on the particle concentration during drying of the deposited ink. Here, all these effects have been modeled, numerically simulated as well as validated experimentally.

Electromagnetic Metamaterials and the Applications : Convergence between Condensed-matter Physics and Photonics

Super-lensing and perfect absorption of electromagnetic (EM) microwaves using metamaterials (MMs), which are one of the recent examples for the convergence between condensed-matter physics and photonics, have been studied vigorously

for the possible applications in EM-wave cautery, hyper-transmitter, super-lens, EM compatibility, solar energy, bolometer, sensor, etc. We have realized the tunable MM hyper-transmitter in the microwave range utilizing simple planar meta-structure. The single-layer MM hyper-transmitter shows that the transmission peak appears at 14 GHz. In case of the dual-layer one, it is possible to control the transmission peak from 5 to 10 GHz. Moreover, all the transmission peaks present transmission over 100%. The reason for being over 100% is also understood. The investigated hyper-transmitter can be used in enhancing the operating distance of the EM wave in many kinds of practical applications.

Perfect absorption of EM microwaves using MMs is a flourishing research field in expecting the potential applications as above. By minimizing the reflectance and eliminating the transmittance, the design and the fabrication of perfect absorbers (PAs) could be realized in various frequency bands, including the GHz and the MHz bands. The problem of EM noise comes to be more serious according to the advent of ubiquitous society. Extended dissemination of high-speed and high-f digital products and smart equipments has made special EM-wave materials used in various fields. We are investigating advanced meta-structures/materials and MMs for EM-wave absorption, MM technology for EM-wave absorption over 99% and ultrawide-band absorption, and MMs for EM-wave absorption independent of incident angle and polarization.

The Wonder of Nanoengineering

Nature offers us a full assortment of atoms, but Nanoengineering is required to put them together in an elegant way to realize functional structures not found in nature.

A particular rich playground for nanotechnology is the so-called III-V semiconductors, made of atoms from columns III and V of the periodic table, and constituting compounds with many useful optical and electronic properties in their own right. Guided by highly accurate simulations of the electronic structure, modern semiconductor optoelectronic devices are literally made atom by atom using advanced growth technology such as molecular beam epitaxy and metal organic chemical vapor deposition to combine these materials in ways to give them new proprieties that neither material has on its own. Modern mastery of materials growth and characterization with the help of such techniques allows high-power and highly efficient functional devices to be made, such as those that convert electrical energy into coherent light or detect light of any wavelength and convert it into an electrical signal.

This talk will present the latest world-class research breakthroughs that have brought quantum engineering to an unprecedented level, creating light detectors and emitters over an extremely wide spectral range from 0.2 to 300 microns.

Optical properties in quasi-one dimensional III-V semiconductorsAndres CantareroUniversity of Valencia, Spain

The crystal structure of most III-V semiconductors nanowires acquire mostly the wurtzite crystal structure instead of the zincblende structure, the natural structure in the bulk counterpart. Concerning their optical properties, some new and

unexpected resonances appear in the luminescence spectrum of very narrow nanowires, providing fundamental parameters of the material itself, with an accuracy unknown to the date. In some nanowires, a new homojunction, wurtzite-zincblende will arise, giving rise to an asymmetric band offset. There appear also new phonon modes, called surface optical phonons, and confined phonon modes. In this talk, we will explore the role of the dimensions in the optical properties of semiconductor nanowires.

Concluding, our results show that i) let-7g functions as a tumor suppressor in EOC, ii) the addition of this miRNA to current testing regimens may improve diagnosis accuracies of EOC and iii) let-7g is expected to become a new prognostic marker.

Unravelling Local Atomic OrderFrank HaarmannRWTH Aachen University, Germany

Intermetallic compounds (IMCs) are a fascinating class of materials with respect to structural chemistry and technological applications such as steel being still the main construction material. Additionally various Al alloys are used as low weight

substances for example in the automotive industry. Our interest focuses on chemical bonding and local ordering of the atoms. We present a new strategy to investigate the local atomic order in IMCs by a combination of diffraction techniques, quantum mechanical (QM) calculations, and NMR. Various examples such as Cu1-x Al2, Sr1-xBaxGa2, and M(Al1-xGax)4 with M = Sr, Ba will be presented for an application of this strategy.

The quasi-binary section of the IMCs MAl4 and MGa4 with M = Sr, Ba was characterized b means of X-ray diffraction, NMR, and QM calculations. The compounds form a solid solution M(Al1-xGax)4 with M = Sr, Ba crystallizing in the BaAl4 type structure with two crystallographic positions for the triel elements, X(4b) and X(5b) (Figure, left). Two types of local ordering of the Al atoms are evident from 27Al NMR experiments: First a preferred occupation of the 4b sites by Al and second a formation of Al pairs with comparably small interatomic distances (Figure, left). This model is supported by QM calculations of the lattice parameter and the NMR coupling parameter.

BiographyFrank Haarmann studied chemistry at the University of Dortmund and obtained his diploma in 1996. The Ph. D. work focusing on molecular motions in solid state was done in the group of Prof. Dr. Herbert Jacobs at University of Dortmund and finished in 2001. During that time he had several stays in major research institutions for elastic and inelastic neutron scattering experiments. In 2001 he moved for a PostDoc to the Max-Planck-Institut für Chemische Physik fester Stoffe in Dresden. From 2009 to 2016 he holds the position as head of a Junior Research Group at RWTH Aachen.

Multifunctional Carbon Nanotube FiberBelen AlemanIMDEA Materials Institute, Spain

Much of the research efforts have been focused on using outstanding properties of carbon-based nanomaterials as carbon nanotubes (CNTs) for various applications, such as high-performance composite materials and electronics. CNTs have

exceptional mechanical, thermal and electrical properties along the tube axis which can be exploited on a macroscopic scale by assembling these nanocarbons into a continuous fiber preferentially oriented parallel to each other and to the fiber axis. CNT fiber can be produced from natural gas by drawing the CNTs directly from the gas phase during their growth by chemical vapor deposition and with a production up to kilometers/day with molecular control of the nanobuilding blocks. CNT fiber presents high-performance mechanical properties (specific tensile strength of 1,5 GPa/SG, modulus of 60 GPa/SG and toughness of 80 J/g), high conductivity (3.5•105 S/m) and its high surface area (260 m2/g) favors its integration with other materials due to an internal area accessible and a consequent charge and load transfer enhancement. Therefore CNT fiber outstanding properties have motivated the research on CNT fiber based hybrids and composites, leading to the development of new multifunctional materials. This is the case of hybrids produced with semiconducting oxides for photoelectrocatalysis and energy harvesting where CNT fiber acts as a current collector. All-solid-state capacitor can be built using polymer electrolyte and CNT fiber electrode, exhibiting excellent electrochemical properties and demonstrating great flexibility and semi-structural behavior. Regarding the final applications of CNT fiber, it is already produced industrially and used in various industries including aerospace.

BiographyBelen Aleman completed her PhD in Physics from Universidad Complutense de Madrid (Spain) in the synthesis and doping of ZnO nanostructures for optoelectronic applications. During her postdoctoral position at Elettra Synchrotron Lightsource (Italy), she specialized in XPS microscopy in nanostructured organic (CNTs, graphene) and inorganic (semiconductor oxides, metal alloys) materials. Nowadays she is a researcher at IMDEA Materials Institute in the Multifunctional Nanocomposites Group where her research focuses on the development of macroscopic materials made up of carbon nanotubes that combine traditional properties of high-performance materials (e.g. mechanical) with the ability to take part in energy transfer processes.

Anderson Transition in MetamaterialsKenneth M. GoldenUniversity of Utah, USA

In 1977 Philip Anderson shared the Nobel Prize in physics for discovering that if a quantum system is sufficiently disordered then the electronic wave functions become localized, which explains the metal-insulator transition. Anderson transitions

have been observed in solids, optics, acoustics, and water waves. In we recently uncovered the hallmarks of the Anderson transition for classical macroscopic transport in two phase composite materials, such as thermal or electrical conduction, without wave interference or scattering effects! As one of the phases in a composite becomes connected and develops long range order, such as the brine phase in sea ice forming channels through which fluid can flow, we observe striking transitional behavior. The eigenvalues of a key random matrix governing transport in the system transition toward obeying universal Wigner-Dyson statistics of the Gaussian Orthogonal Ensemble, and the transport field eigenvectors become delocalized. Our results are related to the behavior of surface plasmon resonances in metal-insulator composites, such as metal films made from depositions of nano-sized metal particles on a dielectric substrate or gold nanoparticles suspended in a liquid, interacting with light in the quasistatic regime. Random matrix universality, discovered in the 1950s during studies of atomic spectra, has emerged in internet signal dynamics, various quantum phenomena, and even the zeros of the famous Riemann zeta function. We found this unexpected behavior by studying human bone microstructures, random resistor networks, and various sea ice structures that are important in climate modeling, ranging in scale from millimeters to kilometers. Our findings open the door to applying methods from Anderson localization to classical phenomena, and exploiting universality in modeling complex macroscopic systems such as Earth's climate.

Interaction between Like Charged Surfaces Medated by Multivalent Stiff Polyelectrolytes Klemen BohincUniversity of Ljubljana, Slovenia

The interaction between charged surfaces, separated by a solution of multivalent polyelectrolytes, was studied theoretically. In my talk I will concentrate on stiff, multivalent polymers on the interaction between charged surfaces. Mean field

theory is not able to describe such highly charged systems. Therefore more advanced theories need to be performed in order to consider such systems. The pressure between two charged surfaces will be calculated. For surface separations shorter than the polymer length the surface-surface interaction is repulsive. When the surface separation is comparable to the length of polymers, the bridging of both surfaces by polymers dominates and leads to an attractive force between them.

The role of graphene in the oxidation processes of copperAlicia de AndrésInstituo de Ciencia de Materiales de Madrid, Spain

The oxidation and corrosion of copper are fundamental issues studied for many decades but the oxidation of copper substrates used as catalysts for graphene synthesis by chemical vapour deposition is still an open problem. Since graphene is an

impermeable one-atom thick membrane, it was foreseen to efficiently protect copper against oxidation. However contradictory results about this protection have been published. We study the oxidation of different types of copper substrates with and without graphene for about one year. We also evaluate the effect of graphene in the re-crystallization and inhomogeneous oxidation of Cu. Our results demonstrate that the morphology of the copper substrate and the initial oxygen content are important factors in the time evolution of the oxidation process. We propose a novel mechanism to explain the enhanced oxidation of polycrystalline copper originated by oxygen encapsulated by the graphene impermeable layer during graphene growth. Graphene is shown to prevent oxidation from atmosphere but also promotes slow oxidation derived by the release of out-of equilibrium encapsulated oxygen. The formation of bubbles after several months evidences this slow release as well as the oxygen content at different depths inside copper for graphene covered samples.

BiographyAlicia de Andrés is PhD in Physics by the Autonomous University of Madrid and, since 2008, Research Professor at the Materials Science Institute in Madrid (ICMM - CSIC). Leader of the Graphene based hybrid materials group and head of the Optical Spectroscopies Laboratory. She has authored over 160 ISI publications.

On the effect of high pressure on transverse effective charges of optical phonons in group-III nitrides and ZnO Alejandro R. Goni1,2

1ICMAB-CSIC, Campus UAB, Spain2ICREA, Spain

The group-III nitride semiconductors InN, GaN and AlN and their alloys constitute a material system of paramount importance in nowadays optoelectronics, as well as ZnO. One salient property of the nitride system is the ability to tune

the fundamental bandgap from the near infrared to the near ultraviolet. This implies an increase in the lattice mismatch with respect to the commonly used substrates as In concentration varies. As a consequence, the built-in strain increases as well. Hence, the knowledge of the dependence on pressure of key parameters that determine the optical, electronic and vibrational properties of these materials is technologically important. An relevant aspect is the relationship between bonding and lattice-dynamical properties. High pressure Raman experiments are particularly suitable to address this issue and the scaling with lattice constant of related magnitudes like bond ionicity and phonon effective charges. A comparative study of the pressure dependence of optical mode vibrations of three group-III nitrides and ZnO is presented. The clear systematics in the magnitude and sign of the pressure coefficient of the transverse effective charge observed for the series SiC, AlN, GaN, InN and ZnO will be discussed in terms of the polarity of the bonds of II-VI compounds as compared to their III-V and IV-IV counterparts.

Mechanical stress evolution during reconstruction of silicon surfacesHidehito AsaokaAdvanced Science Research Center, Japan Atomic Energy Agency, Japan

Stress processes reveal a nature of nano-structural formation. The stress energy and the surface morphology should directly affect each other. We have focused on time evolution of the surface stress and its morphology during initial stage of Ge

nano-structural formation on Bi and H-terminated Si(111) substrates. Real-time observations of the surface stress/strain and the morphology were performed simultaneously by using substrate curvature and reflection high energy electron diffraction (RHEED) methods. As a result, we have determined the values of surface energy on the Bi-terminated Si(111) √3×√3-β and the H-terminated Si(111) 1×1 surfaces that change from the strong tensile Si(111) 7×7 reconstruction. Furthermore, the real-time stress measurements have provided a direct evidence for the stress relaxation in each growth stage of nano-structural formation.

Scattering in a quantum dot: The role of resonancesSolve SelstoOslo and Akershus University College of Applied Sciences, Norway

The dynamics of a system in which an electron is incident on a populated quantum dot is studied by resolving the time dependence of the system. Specifically, one electron is initially at rest in the ground state of the dot, whereas the incident

electron has a narrow velocity distribution. In addition to the probabilities of reflection and transmission, the probability of excitation is found as a function of energy. Moreover, probabilities of both electrons being ejected or both being captured are obtained. The latter process involves spontaneous emission. It is found that the dynamics is strongly influenced by the presence of doubly excited states; reflection becomes considerably more probable in the energetic vicinity of resonances. This, in turn, contributes to an increase in the probability of trapping also the second electron within the dot.

BiographySelstø graduated from the University of Bergen, Norway, in 2006. He has also been engaged at Universidad Autónoma de Madrid, Stockholm's University and the University of Oslo. He is now working as a professor at Oslo and Akershus University College of Applied Sciences. Most of Selstø's research is related to unbound, dynamical quantum mechanical systems. In conducting such theoretical/numerical studies, the development and implementation of adequate numerical methods is essential. Dynamics of electrons within quantum dots is of particular interest.

The Presence of Superconducting behaviour in the Compound HgBa2Can-1CunO2n+2+δ for (n≥4)Emad K. Al-SHAKARCHI and Ali I. Al-JANABIiAl-Nahrain University, Iraq

Hg-based high-temperature superconductors (Hg-HTSs) have a similar structure to other superconducting cuprates. The synthesis of HgBa2Can-1CunO2n+2+δ for (n≥4) was prepared using sealed evacuated quartz tube with Hg-free precursor

Ba2CaCu2O5+δ and Ba2Ca2Cu3O7+δ obtained by solid state reaction. It was carried out to investigate the critical temperature, crystal structures and magnetic susceptibility. It was found that there were more enhancement in the peak intensities of the diffraction patterns, especially at (n=5,6) rather than the phase Hg-1223. The structure showed a tetragonal phase with (a=b=3.8297 Å) for (n=4) and nearly approach for another value of (n). While there is elongation in the c-axis for (n>4), such that c=18.893 Å for n=4, c=22.134 Å for n=5, and c=25.33 Å for n=6. The resistivity measurements showed a decreasing in Tc-values as increasing in the Cu-layers in the structure, Tc=122, 103, 94 K, for n=4,5,6 respectively. The susceptibility measurements showed the presence of superconductivity and enhanced the resistivity behavior for different value of (n).

Optical centers with distributed spectral parameters and giant phonon softening in Gd2O3:Er nanoparticles Anatoly Zatsepin and Yulia KuznetsovaUral Federal University, Russia

Low-dimensional modifications of gadolinium oxide doped with Er3+ ions are of interest as functional materials for devices of nanophotonics, optoelectronics, alternative energy, etc. In this work we study temperature-dependent luminescence

behavior of Er3+ ions and their influence on formation of energy structure of Gd2O3 host lattice. Effect of bimodal distribution of Gd3+ defective centers over the activation energy of quenching has been revealed under the introduction of Er3+ ions even in small concentrations. It results in nontrivial temperature quenching of both intrinsic and activator emission that is described by modified form of Mott’s law accounting the nonequivalence of structural-energy parameters of optical centers. The absorption edge of Gd2O3 at room temperature is found to be formed by the phonon-assisted indirect optical transitions. The appearance of small amount of Er3+ ions (up to 1 mol%) in matrix cause the giant phonon softening that is an order of magnitude higher than the data known for lattice vibrations. This phenomena is probably linked with the localized defective phonon modes.

Electromagnetic Analysis of Microwave/Millimetre wave Structures for Nano-scale MRI with NV CentresSaravana MaruthamuthuIntel GmbH, Germany

Microwave radiation is important in today's society. It is used in communications, radar technology, spectroscopy and many other areas. One major field that depends on microwave radiation is nuclear magnetic resonance (NMR) and

electron spin resonance (ESR) spectroscopy. In spin resonance experiments the magnetic moment of nuclei and electrons in molecules is rotated in a large external magnetic field. The frequency of radiation that is required to rotate the spins depends on the product of the spin gyromagnetic ratio and the magnetic field. A large magnetic field is required in order to polarise the spins, improve the sensitivity of inductive readout, and also to improve the spectral resolution. As a result, the resonant frequency of the spins can be high, as much as 100GHz in high magnetic field experiments.

High magnetic field NMR/ESR experiments therefore require careful design of microwave resonators in order to deliver resonant radiation to the sample (and also to detect the precessing magnetic field of spins in the sample). One drawback of conventional NMR/ESR experiments is that the sample must contain a large amount of spins in order for their magnetic field to be detected via inductive readout. In this thesis, we use a new magnetic sensor called the NV centre in diamond, which allows the magnetic field from as little as one nuclear spin to be detected.

When using a NV centre as the NMR/ESR detector a high magnetic field is not required to polarise the spins, since the NV centre measures a special type of polarisation called statistical polarisation which exists even at low magnetic fields. In addition, the sensitivity of the NV centre to high frequency magnetic fields does not increase, as is the case for inductive detectors. Therefore nanoscale NMR experiments can be performed with the NV centre at low magnetic fields. However, the spectral resolution of the techniques still depends on the magnetic field. Therefore, to improve the amount of information that can be obtained from an NMR spectrum, it is still useful to measure at high magnetic fields. For this reason, this thesis reports on the design of microwave and milli-meter wave structures (operating from 2GHz - 50GHz) that will enable nano-scale NMR experiments with high spectral resolution to be performed.

In addition to performing NMR experiments, the NV centre can also be used as a nano-scale magnetic field intensity (H) mapper, to characterise the microwave modes of various milli-meter wave structure like inductors, transmission line, transformers, couplers and resonators fabricated on printed circuit boards (PCB) and semiconductor packages. This would facilitate the optimum design of these structures and to study the electromagnetic interference caused by them for wide ranging applications like 5G communications, automotive radar, gesture control and spectroscopy. In this work we present the full 3D electromagnetic simulation results of various microwave/millimetre wave resonators used to manipulate the spin of NV centres.

LATTICE STABILITY OF PEROVSKITE LATTICE and IT’s EFFECT on VALENCE STABILITY of CATIONS by MADELUNG LATTICE SITE POTENTIAL

Many functional oxides would take Perovskite structures(ABO3). The major reason should be understood by the fact that Perovskite lattices would have larger Madelung lattice energies than those of other lattices Like NaCl, fluoite, corundum,

spinel, garnet.,etc.

According to the most fundamental ionic model, the total Madelung lattice energy (U) can be expressed by the equation:

Since the ionization potential [loss] can be compensated by high lattice site potential [gain], high valence ion can be stabilized in a lattice site with high lattice-site potential. For example, Ce4+, Pr4+, and Tb4+ can be stabilized in a Fluorite lattice, and more stabilized in the B site of Perovskite ABO3 lattice. Un-common high-valence ions like Co3+, Ni3+, Fe4+ in the B-sites of the Perovskite ABO3 lattices can be explained similarly. On the other hand, those high-valence ions cannot be stabilized in the A site of Perovskites nor various A2O3, like A-type,C-type,Mn2O3,or corundum, lattices thus they take rather common valence states in those cases. The Madelung Lattice energy(U) is Enthalpy at 0 K,thus it consists of ca. 90% of total free energy(G) of the compound. The entropy term by Temperature and PO2 can contribute < 10% of U at 300K. Therefore it might be rather minor effects for those internal lattice potential energy.

Nano-Porous Silicon Composites and Organic Structures as Fluorescent Sensors for Explosive Trace Detection

We present a short review of our research and development in the fields of fluorescent chemical sensors for explosive trace detection. Sensory materials include fluorescent molecules, polymers and nano- porous Si (PSi) composites specific

to the presence of explosive vapors ( nitro- and peroxides based compounds). PSi structures with infiltrated fluorescent chromophores are comprised of high and low porosity layers providing photon confining and resulting in fluorescence band narrowing. As a result, PSi composite sensors exhibit two-signal response: the change of peak intensity and its spectral shift. Such approach allows significantly improve detector sensitivity and selectivity with respect to conventional sensors (sensory materials deposited on flat substrate). Special attention is paid to multi-parametric sensing and sensor array platforms as effective trends for the improvement of analyte classification and quantification. Mechanisms of gas physical and chemical sorption inside PSi nanopores and pores of PSi functional composites are discussed.

Phase Transitions and Thermal and Mechanical Reversibility in Shape Memory AlloysOsman AdiguzelFirat University, Turkey

Shape memory alloys are a class of materials which exhibit dual characteristics called thermoelasticity and superelasticity. The basic processes are thermal and mechanical processes in the processing of these phenomena. Thermoelasticity is

mainly called shape memory effect (SME) and performed by cooling and deforming material in low temperature product phase condition. These alloys recover original shape on heating after this deformation. Shape memory effect is facilitated by martensitic transformation governed by changes in the crystalline structure of the material. Thermal induced martensite occurs as multivariant martensite on cooling from high temperature parent phase region, and ordered parent phase structures turn into twinned structures. Twinned structures turn into detwinned structures on stressing by means of stress induced martensitic transformation. Superelasticity (SE) is also a result of stress induced martensitic transformation and performed in only mechanical manner in the parent austenite phase region. The materials are deformed in the parent phase region, just over Austenite finish temperature, and shape recovery is performed simultaneously upon releasing the applied stress. The ordered parent phase structures turn into the detwinned structures by means of stress induced martensitic transformation, like the deformation step in SME. Loading and unloading paths in stress-strain diagram are different in superelasticity, and hysteresis reveals energy dissipation. Martensitic transformations occur with cooperative movement of atoms by means of lattice invariant shears on a {110} - type plane of austenite matrix which is basal plane of martensite.

Copper based alloys exhibit this property in metastable β- phase region, which has bcc-based structures at high temperature parent phase field. Lattice invariant shear is not uniform in copper alloys and causes to the formation of the layered complex structures with lattice twinning following two ordered reactions on cooling.

In the present contribution, x-ray diffraction and transmission electron microscopy (TEM) studies were carried out on two copper based shape memory CuZnAl and CuAlMn alloys

X-ray diffraction profiles and electron diffraction patterns reveal that both alloys exhibit super lattice reflections inherited from parent phase due to the displacive character of martensitic transformation.

The true solution of 3-d diffraction gratings theory: From Laue’s Equations, Bragg’ Law, Shechtman’s Quasi- Crystals, and BeyondTimir DattaUniversity of South Carolina, USA

In this talk at the ICECMP-2017 event, I retrace the tortuous trajectory of crystallography; how starting with Max Laue’s fecund but imperfect analogy between crystals and three-dimensional diffraction gratings, coherent wave scattering in crystals

has emerged as a blockbuster science. It has revealed the atomic structures from the simple common salt, diamond, and the complex double helix of DNA to meteoritic quasicrystals. Spanning over 100 years classical crystallography has netted over two dozens of Nobel Prizes in Physics, Chemistry and medicine as well as recognized by many other honors.1-2 Nevertheless in the mid 1980’s with Dan Shechtman’s Nobel winning discovery of quasi-crystals, 3 Bragg’s famously successful law was critically stressed, that led the International Union the International Union of Crystallography to a redefinition of crystals.

We enquire where Laue’s equations slipped, where they are strong and where Bragg’s eponymous law exactly fits, to solve, for the first time since 1912 the true solution of 3-d diffraction grating theory. 4 It is argued that the Laue-Bragg dichotomy is a consequence of diffraction–reflection duality, 5 a fact that is not overtly recognized but implied in classic textbooks. 6 Also that a fresh understanding is likely to benefit current needs of modern structure analysis; in particular concerns of imperfect order, short exposure, decreased specimen size and real-space visualization. Arguably, these are some of the exiting challenges in materials science of our time.

Who has seen a free photon?Hayato SaigoNagahama Institute of Bio-Science and Technology, Japan

In this talk a new aspect of the interplay between mathematical-physical arguments and light-matter fusion technologies, making use of the concept of "effective mass" in condensed matter physics, will be introduced, through an investigation on

a fundamental (and seemingly naive) question: Who has seen a free photon?

Since the paper of Newton and Wigner in 1949, it has been known in mathematical physics that any position operator cannot be de_ned for a massless free particle with a non-zero _nite spin, in sharp contrast to the cases of massive particles which can be localized. This statement is clearly in contradiction to the above familiar situations where almost all physicists and engineers have used the notion of ‘position of a photon’ as one of the basic ingredients of theory and application of quantum mechanics. Then, who has seen a free photon?

This dilemma is resolved by introducing the "effective mass" of a photon due to the interaction with matter. The validity of this interpretation is con_rmed in reference to the picture of "polariton", a basic notion in optical and solid physics.

The scenario also applies to more general settings. Any kinds of boundary conditions with _nite volume (like cavity) will make photons heavier and slower, even without a medium. As a striking example, we focus on the role played nanoparticles in the context of "dressed photons" and also propose a new look at the photon-matter interaction, which will provide a brand new platform for the interplay between mathematical-physical arguments and light-matter fusion technologies.

Oxygen Adsorption on Boron-Nitride Nanoribbons Atomically Functionalized with CarbonNavarro-Santos, P., Villanueva Mejia F., Herrera-Bucio R. and Rivera J. LUniversidad Michoacana de San Nicolas de Hidalgo, Mexico

In this work, first principle calculations based on the density functional theory are employed to predict the oxygen adsorption on pristine and carbon doped boron nitride nanoribbons (BNNRs) with armchair topology. The physisorption

and chemisorption states are found in the studied complexes and their binding energies, electronic properties and the charge density difference of the complexes are discussed. The C-doped BNNRs have very different O2 adsorption properties compared with the pristine BNNR. In order to characterize the most active sites of the surfaces, proper reactivity descriptors such as, the Molecular Electrostatic Potential and the Fukui functions are presented. Overall, these properties suggest that the C-doped BNNRs may be useful as a gas sensor or as a catalyst in the oxygen reduction reactions.

In silico infrared spectroscopy of macromolecules in solutionIsabella DaidoneUniversity of L'Aquila, Italy

Infrared (IR) absorption spectra of amide modes (particularly of the amide I mode, mostly corresponding to the peptide-group C=O stretching) have long provided a tool for determining the secondary structure of peptides and proteins. Our

group recently developed a computational approach to calculate amide I IR spectra of peptides and proteins based on the joint use of extended molecular dynamics (MD) simulations and a mixed quantum/classical theoretical methodology: the Perturbed Matrix Method (PMM). As the method makes use of classical MD to provide phase space sampling, statistically relevant sampling of the system configurations can be achieved, which is required for an accurate calculation of the spectra of complex systems. The use of the MD-PMM procedure has allowed the theoretical investigation of the amide I spectra of both helical and β peptides as well as amyloids and peptides unfolded states. Comparison between calculated spectra with experimental IR temperaturedependent and isotope-labelled spectra provided a mean for the interpretation of the experimental spectra at the molecular level. More recently, we focused on modelling the time-dependence of the amide I IR signal, to be compared with experimental time-resolved IR spectra, commonly used to monitor folding kinetics. The possibility of quantitatively modelling time resolved spectra can provide a detailed interpretation of the time evolution of the spectroscopic signal, permitting a full characterization of the kinetics of complex chemical-biochemical processes.

Magnetic Tuning of Metamaterials Resonance by using Amorphous MicrowiresAntonio HernandoInstituto de Magnetismo Aplicado, UCM, Spain

The possibility of tuning the electromagnetic properties of metamaterials with magnetic fields by incorporating amorphous magnetic microwires is demonstrated theoretically and experimentally. The large permeability of these wires at microwave

frequencies allows modifying significantly the induction effects by using a small number of microwires (less than 1% of the volume) and applying magnetic fields of the order of tens of Oe. The physical basis of the magnetic interaction between metamaterials with magnetic microwires and electromagnetic waves are presented. In addition, detailed calculations and experimental results showing good agreement are shown for the case of an array of Split Ring Resonators with Co-based microwires.

Transformation of magnetite/hematite epitaxial bilayers by low energy ion bombardmentM. A. Garcia, S. Ruiz-Gómez, A. Serrano, I. Carabias, A. Mascaraque, L. Pérez, M. A. González Barrio, A. Hernando and O. Rodríguez de la FuenteInstitute of Applied Magnetism UCM & Institute of Ceramic and Glass CSIC, Spain

We show here the partial transformation of an single-crystalline hematite film grown on Au(111) by means of low-energy ion bombardment. The preferential sputtering of oxygen atoms upon ion bombardment allows a partial transformation

of the hematite into magnetite, while the good structural matching of both phases lead to an epitaxial magnetite film. The process is reversible and the hematite film can be recovered upon annealing in controlled O2 atmosphere. The magnetic properties of the magnetite are modified by the presence of the hematite layer leading to an increase of coercivity.

Studying the 3D magnetization of ultrathin and antiphase-boundary free spinel crystalsAdrian QuesadaInstituto de Cerámica y Vidrio (CSIC), Spain

Future advances in nanotechnology rely in part on our ability to accurately engineer high quality oxide-based epitaxial nanostructures with customizable functionalities. However, control of properties at the nanoscale remains a challenge

due to the critical influence of structural defects that proliferate at the ultrathin level, such as surface roughness or antiphase boundaries. Our work demonstrates a route for fabricating highly perfect spinel magnetic nanostructures: ultrathin islands of up to 100 µm2 with atomically flat surfaces and free from antiphase boundaries (APB), which is achieved by reactive molecular beam epitaxial growth on a Ru(0001) surface. Indeed, the spinel islands grow from single crystallographic nuclei and are thus APB-free. The extremely low defect concentration leads to a robust magnetic order -even for thicknesses below 1 nm- and exceptionally large magnetic domains (4 orders of magnitude larger than previously reported). We perform 3D x-ray magnetic circular dichroism inside a photoemission electron microscope (XMCD-PEEM) to obtain the three-dimensional distribution of magnetization in the nanostructures. The 3D magnetization maps have been used as the initial magnetization configuration for micromagnetic simulations of islands with the same lateral and vertical dimensions as the experimental ones. Using XMCD-PEEM in combination with micromagnetic simulations and atomic/magnetic force microscopy allows determining the relevant material parameters underlying the magnetic behavior as well as the influence of specific structural defects. It can be extrapolated to other complex oxide-based heterostructures, opening fascinating opportunities from basic and applied standpoints.

Non-standard MFM imagingAgustina Asenjo Instituto de Ciencia de Materiales de Madrid, CSIC, Spain

Despite decades of advances in magnetic imaging, obtaining direct, quantitative information with high spatial resolution remains an outstanding challenge. The imaging technique most widely used for local characterization is the Magnetic

Force Microscope (MFM). This technique was initially focused on the study of the magnetic storage media, however, its versatility, high spatial resolution and simplicity in operation, led to the widespread use of the MFM in the characterization of thin film, magnetic nanostructures and nanoparticles. The MFM is indeed a very active topic of investigation and new operations modes have being developed in the last years to address its main challenges.

In this work, we present the use of non-standard MFM imaging to gain information about the reversal magnetization process in nanostripes, the domain wall pinning in cylindrical nanowires, the domain configuration in multilayered nanowires, as well as the determination of the easy axis in magnetic nanoparticles. The MFM operation under various environmental conditions -in particular under liquids- have opened the possibility of studying magnetic materials of biological interest.

Annealed gold films as template of gold@iron nanostructuresVictor Lopez-Dominguez Instituto de Magnetismo aplicado Laboratorio “Salvador Velayos", & Instituto de Cerámica y Vidrio, Spain

Annealing of metallic thin films in air provides a simple way to incorporate nanostructures over large areas, and for tailoring the physical properties of the initial film. When the expansion coefficient of the metallic film and the substrate

are different; in the film is promoted the formation of hillocks, subsequent holes growing, and islands agglomeration leading to a discrete structure. For example, a gold thin film deposited onto a glass substrate can be used as a template of gold nanoparticles with a controllable size and morphology, only dependent on the initial thickness of the film and the annealing temperature.

In this talk, I will present a method to fabricate Au@Fe core-shell nanoparticles with combined optical and magnetic properties. The gold nucleuses are obtained by thermal annealing of a gold thin film (thickness below 100 nm) deposited by electron beam vapor deposition onto a glass substrate. The obtained gold nanostructures are used as a template for a second deposition of iron. Controlling the evaporation time is possible to obtain from core-shell nanostructures to gold nanostructures embedded in an iron matrix. The hybrid physical properties of the obtained heterostructures were studied by SQUID magnetometry and Magneto Optical Kerr Effect, and optically characterized by Optical spectroscopy.

The New Stage of Development of Sm2Fe17N3 MagnetsN. Imaoka1,2

1National Institute of Advanced Industrial Science and Technology (AIST), Japan2Asahi Kasei Corporation, Japan

The market for high performance magnets is rapidly growing primarily due to expanding applications of large magnets for electrical vehicles and wind power generators. The global market is estimated to have required over 40 thousand tons in

2016. The production volume is estimated to be around 10 billion dollars by 2020. Currently, most high performance magnets are Nd2Fe14B magnets.

Sm2Fe17N3 compounds are good candidates for high performance magnets because of their high saturation magnetization, strong uniaxial anisotropy field, and extremely high oxidation resistance. Furthermore, their Curie temperature is higher than that of Nd2Fe14B compounds, as a result Sm2Fe17N3 compounds are more suitable for high temperature applications. Since Sm2Fe17N3 compounds decompose into SmN and α-Fe when heated above 600°C, it is fairly difficult to obtain consolidated magnets. Nevertheless, several researchers have attempted to prepare fully dense magnets by using shock compression, aerosol deposition, hot-isostatic press, compression shearing, etc. However, the research is yet to progress enough to be of practical use. This is because this material does not provide any overwhelming advantages other than oxidation resistance, for example, high resistivity or low cost, compared to existing sintered rare-earth magnets. Thus, at present, its application is limited to resin bonded magnets. Consequently, even though nearly thirty years have passed since Sm2Fe17N3 materials were discovered (Trinity College, Asahi-Kasei Co.), the production volume is estimated to be less than one thousand ton per year even now. Takagi et al. (AIST) only recently succeeded in fabricating Sm2Fe17N3 sintered magnets without decomposition, by a low-oxygen process which includes jet-milling in a nitrogen gas-filled box and high-pressure current sintering using fine powder slurries. Moreover, several researchers have recently reported Sm2Fe17N3 powders having high coercivity of 10-25 kOe in comparison with conventional powders. These works demonstrate the potential for application not only to bonded magnets, but also to excellent bulk magnets rivalling the Nd-Fe-B magnets. Furthermore, the “ferrite plating method” (Tokyo tech. & Asahi Kasei Co.), which applies to coating Sm2Fe17N3 powder particles with a ferrite phase, can be proposed as one of possible methods for obtaining magnets that can be operated at high frequencies for advanced applications. This new stage of development of Sm2Fe17N3 magnets has begun now.

Contributed Presentation on MagnetismPilar Marin PalaciosInstituto de Magnetismo Aplicado, Universidad Complutense de Madrid, Spain

The unique magnetic properties of magnetic microwires, in particular its interaction with microwaves, associated with the absence of long-range order and diameter in micrometer range, make them useful for the development of new devices,

sensors and metamaterials. This is why there is a great deal of interest in modifying and controlling the magnetic properties through thermal treatments at different temperatures, thus being able to adapt them to our needs. In this work we study the changes in the magnetic properties due to the stress relaxation and to the nanocrystallization induced by thermal treatments in microwires of composition (Fe2.25Co72.25Si10B15), obtaining important variations in the reflectivity of the microwires at high frequencies.

Extension of Dynamic and Thermodynamic Models of Colloids to Higher Concentrations by Adding an Extra DimensionMiroslav Grmela École Polytechnique de Montreal, Canada

Higher concentration brings more complex interactions. In the modeling, the long range among them enter the energy and the short range are treated usually as constraints. In the static (thermodynamic) modeling, the influence of the constraints

is expressed in changing the entropy. The archetype example is the van Kampen modeling (Phys.Rev.135, A362 (1964)) of the van der Waals gas. In the dynamical modeling the constraints are typically modeled by adding a dissipative motion in an extra dimension. For example, de Gennes introduces in J.Chem.Phys.55, 572 (1971) reptation (diffusion inside a tube representing the constraint), or diffusive motion inside a cell representing the constraint in moderately concentrated suspensions (see Grmela et al, J.NonNewtonian Fluid Mech. 212, 1 (2014)). This type of dynamical consideration of the constraints does not however change the thermodynamics implied by the dynamics.

In order to take into account constraints in dynamics in such a way that they influence both the observed static and dynamic behavior, they have to also change the kinematics of the nodissipative part of the time evolution. This part of the time evolution (the Hamiltonian and reversible time evolution) is then also closely related to the entropy. We demonstrate how the added dimension (the extra dimension can be seen for instance as an internal degree of freedom in an effective cluster formation) brings about changes in both the nondissipative and dissipative dynamics and in both the entropy and the energy.

A reversible large resonant frequency tuning and static deflection of cantilever nanobeam via a phase transformation of sputtered NiTi filmIvo Stachiv1,2

1Czech Academy of Sciences, Czech Republic2Harbin Institute of Technology, Shenzhen Graduate School, China

We proposed and demonstrate a novel active resonant frequency tuning of the cantilever beam utilizing a phase transformation of sputtered NiTi. We show that the cantilever resonant frequencies (static deflection) can be easily

tuned up- and down-ward (changed) just by controlling temperature of sputtered NiTi film. A theoretical model that is capable to qualitatively explain the experimental observations has been developed. This model can also serves as a manual for further design of the tunable resonators utilizing a phase transformation of sputtered smart memory alloy thin film.

Building spectral patterns to distinguish the canonical amide forms in solution: Contribution for metal assisted peptide bond cleavage reactionsWagner A. AlvesFederal University of Rio de Janeiro, Brazil

The high stability of an unactivated amide bond is responsible for its half-life ranging from 350 to 600 years at 25 oC and neutral pH. However, there is physiological need to cleave it due to dynamical processes often present in the living matter.

In this sense, the use of metal complexes has shown to be a valuable strategy to break this kind of bond under nondenaturing conditions of temperature and pH. Biological studies have commonly reported that certain metal ions are efficient to cleave peptide bonds, but a microscopic explanation for their catalytic or inhibitory activities has not been paid so far. Therefore, we have employed simple protic amides as peptide bond models and Raman and IR spectroscopies to characterize their solvates, in the presence of those metal ions, and build a spectral pattern. The planarity of the amide group has been interpreted on the basis of the equilibrium between the OCN (60%) and -OCN+ (40%) forms, where the CO and CN oscillators possess comparable amounts of single and double bond character, and such an interpretation is very well supported by molecular orbital calculations. The preferential formation of each canonical form will depend on the kind of metal and exhibit fully distinct spectra. For instance, the νCO mode (1700 cm-1) is upshifted as extremely high electrostatic potential (φ) metal ions are added, but the replacement for ions containing φ values varying from moderate to low leads to the upshift of the νCN mode (1310 cm-1). These shifts are in excellent agreement with the respective neutral and dipolar amide forms, in which the latter shows good relationship with the catalytic activity of biologically known ions. Recently, we have also observed that the γHNH mode (1190 cm-1), which is inactive in both Raman and IR spectra, is activated in the IR spectrum as the OCN form is stabilized, suggesting that the N atom becomes pyramidal and assuring our methodology.

Lyotropic Liquid Crystalline Nanoparticles are Biomimetic Nanostructures for Drug DeliveryMarco Vinicius ChaudUniversity of Sorocaba, Brazil

INTRODUCTION: Lyotropic liquid crystalline nanoparticles (CLL) are biomimetic nanostructures with an intermediate phase between the crystalline solid and the isotropic liquid (ordered and unordered). The CLs present different architectures formed by the self-organization of lipids in aqueous medium and morphologically the CLL to present a lamellar (malt cross), cubic or hexagonal structure. The emulsified CLL precursor systems favor the delivery and release of lipophilic, amphiphilic and hydrophilic drugs. Curcumin (CUR) is a phytochemical and polyphenolic compound, and has physical-chemical properties and therapeutic potential.

METHODS: In this study, the lipid used was monoolein (Myverol18-92K), as surfactants and hydrotropes were sorbitan monostearate (Span 60®), ethoxylated sorbitan monostearate (Tween 20®) sodium lauryl sulfate (LSS), poloxamer 407 (P407) and CUR as the model drug. The CLL were prepared by the mixture of monoolein, surfactant or hydrotropes and water, under agitation and with temperature control. The CUR was added in the formulations previously selected and dispersed in the CLL precursor emulsified systems. The formulations were evaluated as macroscopic evaluation, centrifugation essay (CE) and thermal variation (VTE), zeta potential (ZP), particle diameter (PD), polydispersity index (PDI), hydrogenionic potential (pH), ion conductivity, differential scanning calorimetry (DSC), infrared spectroscopy (FTIR), mechanical properties (hardness, compressibility, adhesiveness, cohesiveness and mucoadhesion), percentage and dissolution and release profile of CUR.

RESULTS: The CLL precursor emulsion systems were obtained by different preparation techniques with variation of water addition, temperature and agitation, in the which were important for selection of formulations and better experimental conditions for CLL. After physical-chemical stability evaluation and structural characterization the best formulations were selected: F1A50°C, F6, DFA-F6, DFB-F6, in the last three the CUR was incorporated. All these formulations presented CLL in the format of malt cross. The highest percentage of CUR content was observed in the DFA-F6 formulation (70%) and in the dissolution and release study of CUR, the maximum release of CUR was observed after 28h for DFB-F6 formulation (30%). Furthermore, the DSC curves showed a change in the crystalline state of CUR. The curves obtained by FTIR showed that the stretches of the CUR chemical groups remained unchanged. The mechanical properties have been found useful for the development of novel dosage forms and routes of administration.

CONCLUSION: Thus, the experimental conditions employed allowed to obtain CLL precursor systems in the malt cross format and potential for the use of CUR.

Transmission Electron Microscopy characterization of the uniaxial relaxor SBN (Sr0.67Ba0.33Nb2O6)Estradé, S1, López-Conesa, L.1, Eljarrat, A.1, Rebled, J.M.1,2, Ruiz, A.1, Dezanneau, G.3, Torres-Pardo4, A., Ruiz-González, L. 4, González-Calbet, J.M. 4 and Peiró, F1

SBN belongs to the tetragonal tungsten bronze (TTB) family of uniaxial ferroelectric relaxor materials, with a single component polarization vector pointing along the tetragonal c axis. High response coefficients and an enhanced width of

the high response regime around the ordering temperature 'Tm' make of relaxors promising systems for applications such as piezoelectric/electrostrictive actuators and sensors.

The idealized structure of SBN, with the generalized formula A2B4C4Nb2Nb8O30, has three types of structural channels along the c axis, formed by two types of crystallographically independent NbO6 octahedra. Disorder due to presence of voids in A cation sites (occupied by Sr atoms) and random distribution of Ba and Sr in B cation sites are thought to be responsible for the relaxor behavior, via the formation of random electric fields and, subsequently, polar nanodomains oriented in the only easy polarization axis c, without a structural change occurring in the phase transition. In this work we present structural, chemical and dielectric studies of a SBN single crystal by means of Selected Area Electron Diffraction (SAED), High Angular Annular Dark Field (HAADF), Annular Bright Field (ABF) and Electron Energy Loss Spectroscopy (EELS) along the [001] and [100] zone axes. Experiments were carried out in non-aberration corrected (Phillips CM30, JEOL J2100, JEOL2010F) and probe-corrected (Titan3 G2, ARM cF200) TEMs.

A direct test for matter-antimatter – Imbalance in the Universe, and how we detect itPetteri PusaUniversity of Liverpool, UK

One of the biggest mysteries in modern physics is that antimatter seems to have been disappeared from the Universe. According to the standard model of physics, there should have been equal amount of matter and antimatter produced in

the Big Bang. However, we don’t see any trace of antimatter, at least in the observable Universe.

One possible explanation is that CPT –symmetry, the corner stone of the standard model, is somehow violated.

The ALPHA –experiment, situated at CERN’s Antiproton Decelerator, has now developed a direct way to precisely address this question. This is done by comparing the properties of hydrogen atom to its anti-world counterpart, antihydrogen. The most recent findings by the collaboration indicate that antihydrogen behaves similarly to hydrogen, in precision less than one part of billion [1].

However, properties of hydrogen have been measured five orders of magnitude beyond this. ALPHA is currently aiming to improve precision of the measurements of antihydrogen to see if there are any statistically observably differences in the properties in these two atoms.

In this talk, a review of recent progress, along with methods to create neutral antimatter, how to trap it, how to diagnose and detect it, is given. A review of the progress in the field of low energy antimatters physics will also be discussed.

In the present work, MgFe2O4 nanoparticles were prepared by sol-gel auto-combustion method, using glycine as fuel agent. Transmission electron microscopy and scanning electron microscopy (SEM) provided the data on morphological analysis

and particle sizes. Structural characterization was performed with X-ray diffraction which has given data about the spinel single-phase formation. Chemical structure has been characterized by Fourier-transform infrared spectroscopy and by X-ray photoelectron spectroscopy which proved the absence of organic phases. The magnetic properties investigated by vibrating sample magnetometry and electron paramagnetic spectroscopy show that the ferrite particles are superparamagnetic behaviour, depending on the chemical composition, shape and size of the particles, the synthesis method, crystallinity, direction of magnetization and cation distribution. Dielectric properties were evaluated by dielectric permittivity and dielectric losses measurements, using an Agilent 4294A Precision Impedance Analyzer, in the range of 40 Hz - 110 MHz.

Treatments of fluoride (F), copper (Cu) and F-Cu from semiconductor-based silicon etching rinse baths by electrocoagulation (EC) using aluminum plate electrodes were investigated in this study. The effects of important process variables such

as current intensity, initial pH and initial concentration on the removal efficiencies of F and Cu were evaluated. Removal efficiencies for F and Cu in the single system were found at about 99% at optimum operating conditions.The highest removal efficiencies were achieved at pH 3 for F and between pH 3 and 5 for Cu containing synthetic wastewaters. Experiments were conducted with different F/Cu ratio when Cu concentration was kept constant and F concentration was increased, the highest removal efficiency was observed at lower concentrations. EC study provided high removal efficiencies of F and Cu from semiconductor synthetic wastewater.

Disadvantages of field electrons sources based on silicon are high sensitivity to the surface state and low density of field emission currents, which is about 50-150 μA/cm2. However, this is not enough to create vacuum field effect transistors

with a high output power.

The purpose of this work is to study the effect of modification and non-lithographic nanostructuring of various types conductivity silicon crystals surface on the field emission characteristics of electron field sources made on their basis.

The kinetics of the morphology of the surface of silicon crystals at the initial stages of microwave plasma-chemical deposition of a carbon coating was studied. Three stages of the process have pointed: 1- plasma-chemical etching of natural silicon oxide, 2- deposition of atomic carbon, 3-phase rearrangement of the silicon surface layer. The result of the process is the self-organization of carbon condensate into nanoscale silicon-carbon islets-domains. Their using as a mask coating for high-anisotropic plasma-chemical etching makes possibility to obtain multi-tip autoemission structures on surface. The surface density of the obtained field emission tips is 2-3 greater than the surface density of the emitter arrays produced by traditional lithographic techniques.

The interrelation of the morphological and field emission characteristics of surface-structured silicon crystals is determined by the type of semiconductor conductivity. The autoemission threshold voltage is decrease several times due to the removal of the natural oxide coating and the carbon modification of the surface. Emission current densities are increased more than one order in comparison with the current densities of emitter arrays obtained by using of regular microtechnologies.

Novel luminescent system Gd3Ga3Al2O12 doped with Eu, Tb and Ce ionsPiotr Solarz1, Robert M. Kowalski1, Radosław Lisiecki, Paweł Głuchowski, Bogusław Macalik1, Tomasz Niedźwiedzki1, Witold Ryba-Romanowski1, Michał Głowacki2, Marek Berkowski21Institute of Low Temperature and Structure Research PAS, Poland2 Institute of Physics PAS, Warsaw, Poland

Gd3Ga3Al2O12 (GGAG) single crystals belong to garnet group crystallize in the cubic crystal structure with space group Ia-3d (Z = 8). Gd3+ ions enter dodecahedral positions, surrounded by 8 oxygens (positions 24c in Wyckoff notation) while

Ga3+ and Al3+ occupies tetrahedral (24d) and octahedral (16a) positions surrounded by 4 and 6 oxygen ions respectively. It has been found that active dopant can be situated in other sites in this solid solution host. Garnet crystal, especially Y3Al5O12 (YAG) doped with Ce3+ are commercially used as phosphors in LED devices. However due to the limitation in red emission such sources possess low Colour Rendering Index (CRI) value. That problem could be resolved in co-doped with many lanthanide pairs, since energy transfer processes between Ce and Tb, or Tb and Eu in other materials has been published in literature, earlier.

To find energy transfer processes the site selective spectroscopy and kinetics analysis of metastable multiplets were investigated versus temperature in single crystals, to avoid uncertainty of crystal structure.

In this work, we investigate the influent of Eu, Tb, Eu-Tb and Eu-Tb-Ce activator composition. For all investigated materials the multiplet energies and structure of the bands were investigated in the range of 5 to 300 K. It was found that the composition of Eu-Tb-Ce shows the highest level of luminescence.

Spin Orbit Coupled Bose Einstein Condensate in a Two Dimensional Bichromatic Optical LatticeZuleyha OztasAnadolu University, Turkey

We study noninteracting and weakly interacting spin orbit coupled Bose Einstein Condensate (BEC) in a two dimensional quasi periodic bichromatic optical lattice (BOL) using numerical methods. We use sine and cosine typed BOL potentials

which are generated by two standing wave polarized laser beams of incommensurate wavelengths in the x and y directions and calculate the density profiles of spin orbit coupled BEC numerically. The numerical solution is performed by imaginary time split step Fourier method. We investigate the localized states which are stationary for an equal occupation in the pseudo spin states. The effects of spin orbit and Rabi couplings on the localization of BEC are investigated. We also study the effects of weak interactions on localization.

Silica microstructural and mechanical characterization intended for photovoltaic applicationAissa kefaifi, Tahar SAHRAOUI and Abdelkrim KHELOUFICRTSE, Algeria

The solar grade silicon for photovoltaic cells manufacture needs high purity. In this, three successive stages can be distinguished: silica enrichment, carborhermic process and purification for obtaining high purity solar grade silicon (SoG).

Our work was focused on the study of the relationship between the silica microstructural, mechanical characterization and its behavior at high temperature. For this, we used the optical microscopy and Vickers hardness techniques. These techniques allowed us to reveal the defects existing in the silica structure, such as inclusions and microcracks. The studies confirm the existence of these imperfections which caused the silica bursting and consequently the production of fine particles. These particles had a negative influence on the downstream processes. The results allowed us to identify a correlation between the silica microstructure, mechanical properties as well as the behavior at high temperature in the electric arc furnace during the carbothermic process.

Metal modified B-N@Graphene for highly selective toxic gas sensorMd Delowar HossainThe Hong Kong University of Science and Technology, Hong Kong

The industries and automobiles generates lots of toxic gases which vigorously affect human health, environment, and global climates. So, gas sensors can play a great role to detect the presence of these toxic gases. Semiconductor based gas sensors

are highly demanding because their exceptional stability and surface reactivity at ambient conditions. Generally graphene is a zero band gap material. So, we aim to produce B-N doped graphene to generate band gap and then finally incorporate some metals to enhance the chemisorption and selectivity to target gases. In our present project we used gold metal for N-@graphene where gold accumulate some charges on it from N-doped graphene, so electrophilic gases are easily adsorped on gold surface. On the other hand, we used titanium metal for B-@graphene where positive B-doped graphene substract electron from Ti atom making it more electrically positive, so gas with lone pair electron easily adsorbs on Ti surface.

Characteristics of Nanosecond Discharge in Air In ‘Needle – Electrolyte Surface "Electrode System’O.K. Shuaibov1and V.I. Chyhin2

1Uzhgorod National University, Ukraine2Land Forces National Academy, Ukraine

Using of "needle- electrolyte surface" gaps with switching pulse condenser of low capacitance is the most widespread. The purpose of this work was to develop and investigate the characteristics of nanosecond discharge plasma-chemical

reactor in the "metal blade – electrolyte surface" system in the air of atmospheric pressure. This reactor can be used for the synthesis of colloidal solution of copper-based nanostructures. To study characteristics of nanosecond discharge in air of atmospheric pressure over the surface of copper sulfate solution it was used the discharge cell with the complicated system of electrodes. The top electrode consists of the system of metal blades and the lower electrode is made as the metal plate placed in the solution.

After work of the discharge device within 2-3 hours the solution changed its color from blue to green. This can indicate the transformation of solution based on products of electrolytic dissociation of the copper sulfate in colloidal solution of copper nanostructures. The peak voltage was about 50 kV, and current – near 75 A. The maximum value of electric power of nanosecond pulsed discharge was equal to 2 MW.

Investigations of nanosecond discharge characteristics over the surface of copper sulfate showed that it ignited in the uniform set of plasma thin films attached to tip of blades. This appearance of discharge may be caused by an influence of the pre-ionization by escape electron beam and accompanying X-rays. The easy ionized impurities of water vapor and products of dissociation of salts exist in the discharge gap.

Over the past years, the photovoltaics (PV) industry has been experiencing a strong economic growth worldwide. This development is due to an increasing demand for PV modules which is anticipated to continue in the coming years. The

dominant semiconductor material used in PV industry is silicon. A major portion of the silicon is wasted in the PV industry. The recovery and recycling of high-purity silicon from kerf slurry waste will be steadily increasing importance in the coming years. Therefore, the focus has to be set at the detection of potentially usable secondary resources and the development of inexpensive and energy-saving processes to recover the silicon from kerf slurry waste. In this literature review, emphasis is put on the recycling and refining of silicon for reuse in the PV industry. This review paper gives an insight into recently published scientific articles in which the valorization of kerf slurry waste has been studied.

Recently, it has been demonstrated that evanescent electric fields photo-generated on the surface of photorefractive crystals, allow patterning the crystal surface with micro and nano-objects. This optoelectronic trapping method, known as

Photovoltaic Tweezers provides great flexibility to assembly different structures, which make it a unique way to functionalize the surface of photorefractive crystals. Metallic nanoparticles are well known for their remarkable capabilities in confining the electric field into the nanoscale when they are suitable illuminated. Their plasmonic properties determine their suitability for enhance different phenomena such as fluorescence of molecules placed in the surroundings or Raman emission. Zeolites are nano-porous crystals with high capabilities to be functionalized. There is a large variety of families and each one can be used for a different purpose, depending on their features such as shape, porous size, or dimension. In this work, we report the use of Photovoltaic Tweezers for the fabrication of metallic and dielectric structures on top of Fe:LiNbO3 photorefractive substrates with different applications: a) Ag metallic structures for studying their capabilities as plasmonic platforms for enhance the fluorescence of some dyes (DR1, fluoresceine). b) Orientation and patterning of anisotropic dielectric objects such as cylindrical zeolites L type, by the action of the photovoltaic fields, to take advantage of the alignment properties. Although we are in the first stage, we look forward to be able to mix both concepts, that is, fabrication of metallic structures from metallic non-spherical particles suitable aligned in order to improve their plasmonic properties.

Tunnable Josephson Transport in hybrid Superconductors-Quantum dots nano- junction: A many body theoretical model approachAjayIndian Institute of Technology (IIT) Roorkee, India

The present talk initially introduce the Josephson quantum transport and possibility of new electronic devices based on Josephson effect and tunable supercurrent when two superconducting electrodes are connected to quantum dot, multiple

coupled quantum dots and magnetic quantum dot as well. Recent experimental and theoretical advancement indicated a growing interest in the new physics related to electronic transport behavior in superconductors-quantum dots hybrid Josephson Junctions and related challenges. The present talk will also focus on the theoretical modeling of the electronic transport through interacting multiple coupled Quantum dots connected to superconducting leads having s-wave symmetry of the superconducting order parameter which can be further extended for the high Tc superconductor having d-wave of superconducting order parameter. For this purpose, the various terms in renormalized Anderson model that includes the coupling of superconducting leads with the Quantum dots, repulsive Coulomb interaction on the dot states and attractive BCS effective interaction in superconducting leads and many body effects leading to interplay between Superconductivity, Kondo effect and RKKY interaction will also be highlighted. To solve such model many body Hamiltonian for Josephson supercurrent the techniques like Keldysh non-equilibrium Green’s function and Ambegaokar-Baratoff approaches will also be discussed. Finally, we will compare the theoretical results based on the above approach of our research group with existing experimental and other theoretical investigations for potential applications in Josephson electronic nano-junction and future direction.

The Possibility of Band Gap Formation in Graphene by the Addition of Extra Graphene LayersAlexey DementjevNRC “Kurchatov Institute”, Moscow

Band gap creation and engineering is crucial for the realization of graphene’s potential as an electronic material that supplements or replaces silicon. The aim of this work is to discuss the possibility of the band gap formation in single

layer graphene by the addition of extra graphene layers. The discussion is based on the Auger spectroscopy experimental data which allows monitoring density of states in -bands of multilayered graphenes. The density of states in -bands changes from zero at the top layer to the maximum near 5th-6 th layer. The density of states in each layer results from pz→π electron transition of this layer. The interaction between -electrons from different layers is absent. As the density of states in top layer 1 is zero, new layers A and B are deposited on top of layer 1. As a result -bands and band gap are formed under layers A and B. The band gap may be opened by the current in layer 2 using active the Coulomb drag or by irradiation. The proposed idea simplifies the practical implementation of graphene as it allows using a top layer of any MLG as a single layered graphene material, but the experimental confirmation is required

Modelling the Asymmetric Magnetic Recording Heads with an Underlayer Using Multiple-Images Method Ammar Edress MohmaedDuhok Polytechnic University, Iraq

The magnetic potential and field for two-dimensional semi-infinite structured ring head with a finite gap was a subject of intensive interest. In this work the Multiple Images’ methods solution based on a using the method of images which is

suggested by Shut, and Bertram for evaluating the horizontal head field only. A single image method is also discussed with focusing on the analysis of perpendicular head fields for a special case when the head surface -to-underlayer is equal to the head gap length. The surface potential of asymmetrical magnetic recording heads in the absence of a soft underlayer is employed as an approximation, long with the appropriate Green’s functions to determine the potential and fields everywhere. The results follow closely the corners, while the gap region shows linear behaviour for d/g < 0.5 compared with the calculated fields from finite-element the reason of the disagreement caused by using the potential for head without underlayer case. The second method is superposition technique, which utilising the principle of the single image method for d=g. It was found that for the head with the underlayer present, the superposition (single image method) results follow closely the shape of the calculated fields from finite-element modelling. The results show that y field component based on the superposition (single image method) compared with the finite-element calculations are in a very good agreement for angles up to 45 for y/g ≤ 0.1.

Antimicrobial photodynamic therapies and the need guidelines to standardized test to in vitro studiesRezusta AUniversidad de Zaragoza, Spain

The development of antimicrobial resistance is a natural or acquired phenomenon in microorganisms, and is accelerated by the selective pressure exerted by use of antimicrobial agents in humans, animals and agriculture. Photodynamic therapy

(PDT) is a treatment that uses special drugs, called photosensitizing (PS) agents, along with light to kill mammalian or microbial cells PDT is a technique that utilizes reactive oxygen species produced by non-toxic dye or photosensitizer molecules in the presence of low intensity visible light to kill. The PDT has been useful in: i) the management of airway disease in adults; ii) palliative or adjunctive therapy used to relieve non-life-threatening symptomatic airway obstruction (eg, dyspnea, cough, hemoptysis) due to malignant or, less commonly, benign conditions that are not amenable to Pirst-line therapies; iii) the treatment of oesophageal cancer and Barrett's oesophagus; iv) the palliation of oesophageal cancer; v) treatment of actinic keratosis, in situ; vi) cutaneous squamous cell carcinoma and basal cell carcinoma; vii) onychomycosis management; viii) cutaneous leishmaniasis; ix) sporotrichosis treatment; x) PDT (with or without intravitreal bevacizumab, aPlibercept, or ranibizumab) for patients who fail to respond to initial anti- vascular endothelial growth factor therapies Age-related macular degeneration; xi); infectious keratitis; xii adjuvant to non-surgical periodontal therapy in patients with diabetes mellitus; xiii)

decolonization of pathogens on skin; xiv) treatments of the oral cavity like periodontitis and root canal infection and xv) superinfected burn wounds. An important evolution is the combined nanoparticles and PS. The most commonly used photosensitizers (PS) in the United States is porPimer sodium and aminolaevulinic acid, whereas in Europe methyl-aminolevulinate and aminolaevulinic acid are preferred. Not all the photosensitizers have the same photodynamic effect against the different microorganims. The determination of the antimicrobial susceptibilities of signiPicant microorganism isolates is one of the principal functions of clinical microbiology laboratories. The in vitro studies are a tool to establish the most effective PS for each pathogen, and it will be necessary to establish the correct treatment, as it has been shown in sporotrichosis. We think that it is time to establish an international guidelines like the clinical laboratory standards institute or the European committee on antimicrobial susceptibility Testing.

In conclusion PDT is a promising tool to management patients, but we need to standardize the methodology to determine in vitro studies sensitivity test and clinical managment.

Phase Transitions in Metal Oxide Semiconductors Induced by Laser RadiationArturs Medvids1, Pavels Onufrijevs1, Edvins Dauksta1,2, Hidenori Mimura2 1Riga Technical University, Latvia2Shizuoka University, Japan

In this study, the effects of Nd:YAG laser radiation on TiO2 and ZnO crystals were investigated with aim to show the possibility of phase transitions rutile–anatase in TiO2:Nb and metallic Zn phase formation in ZnO crystals. TiO2 with 0.05

wt% Nb doping and pure ZnO crystals were used in experiments. The TiO2 and ZnO crystals were irradiated by Nd:YAG laser with following parameters: λ=266 nm, τ=3 ns, intensity till 290 MW/cm2. Raman spectra revealed, that the TiO2 crystal was in rutile phase before the irradiation, but after irradiation the crystal is transformed into the anatase phase. Morphology of the irradiated surface is shown formation of ball-like nanostructures with small nanoparticles around with size distribution from 10 till 30 nm. These nanoparticles consist of different material, maybe TiO2 or Nb, because they surfaces unwettable. Irradiation of the ZnO crystals by the laser with intensity I=290.0 MW/cm2 leads to “black ZnO” formation. The measurement of optical transmittance spectra of ZnO crystals irradiated by the laser revealed a minimum at λ=750 nm. This fact is explained by presence of surface plasmon resonance in Zn nanoparticles. Irradiation of ZnO crystal by strongly absorbed laser radiation leads to generation and redistribution of intrinsic defects: Zn interstitials (Zni) and vacancies (VZn) due to present of temperature gradient. Zni are concentrated at the irradiated surface, but VZn in the volume of the crystal. As a results, conductivity of the crystal is increased up to 103 times. At intensity of laser more than 290 MW/cm2 Zni agglomeration to nanoparticles take place. An evidence of Zn phase formation in ZnO crystal is appearance of E2g band at 70 cm-1 in Raman spectra after irradiation by the laser.

Probing matter with Fourier AcousticsBarnana PalSaha Institute of Nuclear Physics, India

Pulsed acoustics is established to be an important tool with wide applications in physical, chemical and biological sciences. Wave propagation in a system is characteristics of the inherent properties of the propagating medium. An inevitable

consequence of wave propagation is dissipation or loss of wave energy during its propagation through the medium. Study of the dissipation mechanism has importance in understanding the dynamical properties of the medium itself and precision measurement of attenuation constant is a key factor in such studies. In spite of due efforts towards increasing the accuracy of attenuation measurements, experimentalists find it difficult to achieve reasonably consistent and reproducible values for the attenuation constant. The present talk will discuss the limitations of pulsed acoustic methods and possible remedies in this connection.

Hydrogen Storage in Metal Doped Noble Carbon Nanostructures: Controlling Storage Capacity & Desorption TemperatureBrahmananda ChakrabortyBhabha Atomic Research Centre, India

One of the greatest challenges of this century is to find an alternative fuel for vehicular propulsion. In this regard hydrogen is an ideal fuel as it is abundant and environment friendly. The present hydrogen storage technologies namely; high

pressure tank and liquid state storage are not applicable primarily because of large size and higher energy cost for liquefaction. The solid state storage may become a viable technology provided the storage medium can adsorb large amount (6.5 wt%) of hydrogen and can release them easily. For pure carbon nanostructures, the physisorption of hydrogen is negligible at room temperature. The carbon nanostructures functionalized by transition metals are the promising candidates for hydrogen storage media at ambient conditions.

This talk will present DFT (Density Functional Theory) results on interaction, charge transfer mechanism and hydrogen storage capability of various 3d and 4d transition metals attached on noble carbon nanostructure (Nanotube, Graphene, Graphyne). We predict that transition metals with lower Ionization Potential and less number of d electrons have better hydrogen adsorption capabilities. The desorption kinetics, nature of bonding, hydrogen weight percentage and stability of the structures will be highlighted to achieve high storage recyclable hydrogen storage in transition metals doped noble carbon nanostructures.

Identifying Inorganic Molecules on reactive MoS2 defects by ab-initio Scanning Probe Microscopy SimulationsCésar GonzalezIFIMAC, Universidad Autónoma de Madrid, Spain

Since graphene was discovered some years ago, the interest in two dimensional (2D) materials has grown exponentially. The so-called transition-metal di-chalcogenides have recently attracted great attention due to their promising properties.

One of the most studied compounds is MoS2 due to its potential nano-opto-electronic applications. Very recently, this material has been proposed as a fundamental part in gas sensors. In those cases, the molecules were weakly bonded by van der Waals (vdW) forces to the poorly reactive MoS2 substrate, changing the electric current measured in the sensor.

In this work, we have performed density functional theory (DFT) simulations in order to find the most stable structures of small inorganic molecules (such as H2O, N2, O2, CO, NO and CO2) adsorbed on different point defects of the MoS2 monolayer. Our results show that the molecules are bonded to the Mo atoms in the defective monolayer (the Sulphur divacancy occupied by two Mo atoms). Once the molecules are bonded to this point, they can be identified using the Scanning Probe Microscopies (SPM). Following the original idea of chemical identification proposed some years ago, each molecule will lead to a different force curve when an atomic force microscope (AFM) tip is approached. At the same time, the use of a metallic tip allows the calculation of the conductance as a second fingerprint. This parameter helps to elucidate the kind of molecule adsorbed in cases with comparable force. Using both parameters, the molecules will be identified in future experimental measurements.

Nanobiotechnology as operating with the bodies of biological semiotic means (nanobiotechnology and biosemiotics)Chebanov Sergey Saint Petersburg State University (SPSU), Russia

Since ancient times people interested in the question of the existence of the language of animals. In the study of marriage, territorial , group , etc., animal behavior has become clear that a variety of animals (mammals, birds, fish, insects ,

crustaceans, molluscs ) using different kinds of signs (semiotic means) to interact with each other. These semiotic means are analog of language of animals. This circumstance became the basis for emergence of biosemiotics (zoosemiotics) as the discipline studying semiotics means of living beings (F.S.Rothschild, Yu.S.Stepanov, Th.Sebeok). Clarification in the 1950-60th of the genetic code structure (J.Watson, F.Crick, F.Jacob, J.Monod) led to understanding of that genetic processes have the semiotics nature. After that it became clear that any biological life has the semiotics nature and it is necessary to speak about semiotics realized biology (H.Pattee). Thus many fundamental biological processes have the semiotics nature. These are the genetic code, signal peptides, neurotransmitters, immune interactions, hormones , conditioned reflex reaction, pheromones , attractants, etc. It is very interesting that basic biosemiotic objects have nano-dimensions (diameter of DNA molecule is 2 nm, step of spiral is 3 nm; the size of t-RNA, signal oligopeptides, antibodies are 5-20 nm; synaptic bubbles – 50 nm, diameter of sticks of retina of eye – 6 nm, etc.). In that case it appears that biosemiotics processes are natural nanobiotechnologies (A.M.Ugolev), biosemiotic researches are laboratory biosemiotic nanobiotechnologies, and methods of genetic engineering, editing of a genome, screening of a genome, molecular therapy, etc. are industrial biosemiotics nanobiotechnologies.

Wireless optical signal availability and link range analyses over strong fluctuating meteorological conditions with case study in SenegalCheikh Amadou Bamba Dath, Aliou Niane, Modou Mbaye and Ndéye Arame Boye FayeUniversité Cheikh Anta Diop de Dakar (UCAD)

Objectives: Free-Space Optics (FSO) can provide high data rate, up to 10 Gbps. The performances of FSO systems are generally affected by weather conditions. In that paper we establish percentages of availabilities, the power margins and optimal link ranges of some FSO systems, for different strong meteorological conditions in Senegal.

Methods/Statistical analysis: Received signal and availability of FSO links are subject to link distance and meteorological conditions like, clear atmosphere, rain, and sandstorm or in presence of heavy dust. In this paper we investigate the effects of weather conditions on the performance of FSO links, taking the climate of Senegal as a case study.

However, the effect of turbulence induced irradiance fluctuation, varying beam divergence angle and misalignment conditions, and their impacts on the performances of the FSO systems were analyzed and estimated.

Based on visibilities data recorded from 2003 to 2014, particular FSO link optimization’s simulation cases were analyzed, in terms of power margin, availability and maximum distance. The results were performed by a lognormal distribution with good precision of the tests of correlations.

Findings: range and availability of optical link for different weather conditions are established easily and with high precision. As there is no known study on the effects of weather conditions in this country, this paper offers an attempt to analyze and identify the challenges related to the deployment and optimization of FSO systems under Senegalese’s weather.

Application/Improvements: For more flexibility, we forecast using an application programming interface to make easy use of the modeling approach by professional and academic actors. We plan to extend the study in all the cities in Senegal and for the Sahel region.

Study of the angular momentum of light from plasmonic crystals H. C. OngThe Chinese University of Hong Kong, Hong Kong

In analogy to electron waves, electromagnetic waves also carry spin and orbital angular momentum (AM) and this property has been fascinating the world of optical science and engineering for many years. With the rise of nanotechnology, photonic

systems can now be fabricated at the length scale of nanometers, manifesting many intriguing phenomena including the spin-orbit interaction in an observable extent. The polarization, the spatial field distribution, and the propagation direction are no longer treated separately and control one with another has become feasible. Plasmonic arrays are one of the most popular nanophotonic systems owing to their simplicity and well-defined structures for yielding controllable optical properties. They have been used in extraordinary transmission, fluorescence, photovoltaics, nonlinear optics, sensing, etc. In addition, since surface plasmon polaritons (SPPs) carry transverse spin AM, they should modify the AM of the outgoing radiation under the conservation of angular momentum. Unfortunately, this transverse spin is not properly taken into consideration even though plasmonic research has been carried out for years. Here, I will talk about the AM of light from plasmonic crystals. We have observed substantial polarization conversion and spin-orbital coupling from square lattice circular nanohole arrays, which do not possess intrinsic chirality. We find the transverse spin AM possessed by SPPs play a deterministic role in governing the far-field radiation. The experimental results are supported by finite-difference time-domain simulations and temporal coupled mode theory. Based on the AM study, we propose the AM can be used as a new parameter in surface plasmon resonance (SPR) sensing. As the transverse spin AM of SPPs is strongly dependent on the complex propagation wavevector, which is sensitive to the change of the local refractive index, the change in the AM of light thus reflects the sensing environment. The performance of the spin-SPR will be discussed.

Quasi-One-Dimensional SuperconductivityKonstantin Yu. Arutyunov 1,2

1 National Research University Higher School of Economics, Moscow, Russia 2 Kapitza Institute for Physical Problems, Moscow, Russia

Superconducting properties of metallic nanowires can be entirely different from those of bulk superconductors because of the dominating role played by fluctuations of the order parameter. For superconducting channels with diameters below

30 nm fluctuations of the phase of the complex order parameter - the phase slippage - lead to non-zero resistance below the critical temperature and suppression of persistent currents. Fluctuations of the modulus of the complex order parameter broaden the gap edge of the quasiparticle energy spectrum and modify the density of states. In extreme case of very narrow channels imbedded in high-impedance environment (which fix the charge and, hence, enable strong fluctuations of the quantum-conjugated variable, the phase) the superconductor can be driven to insulating state – the Coulomb blockade. We review recent experimental activities in the field demonstrating rather unusual phenomena.

Study of atomic arrangements and charge distribution on the Si(001) surfaces adsorbed a Ge atom by DFTB simulationsLin Zhang Northeastern University, China

SiGe/Si heterogeneous materials have been widely used in microelectronics and optoelectronic devices. Preparation of precise and controllable SiGe/Si heterogeneous nanometer materials is an effective means to improve the performance of

electronic devices. Density Functional Tight Binding (DFTB) simulations are performed to study atomic arrangements and charge distribution on Si(001) surfaces with one Ge atom adsorbate. For these Ge/Si(001) systems, the height between the Ge atom and the surface, and the adsorption position being relative to the Si dimers on the surfaces, which have influences on the stable structures of the Ge atom adsorbed on the Si surface. Firstly, two reconstructed Si(001) surfaces including c (4×2) and p (2×2) are obtained based on the total-energy minimization calculations. Then, the Ge atom is placed on these Si surfaces. The simulation results show the following results. For these dimers formed on these two Si(001) surfaces, dimer’s bond length, and the buckling angle between the dimer and the surface present apparent differences as well as the charge distribution of these two surfaces. If the distance between the Ge atom and the surface is large, the Ge atom prefers to be locate at the top position of one atom of the dimer, whereas the distance is small, it at the bridge position of this dimer. In these systems, the Ge atom always loses charges, and the charge transfer is found between atoms.

Spatial Orientation and Order of Molecular Subunits in Films of Organic SemiconductorsA. M. Anton and F. KremerLeipzig University, Germany

Conjugated donor/acceptor copolymers have obtained significant attention due to their soft matter properties combined with semiconducting characteristics, which allows for their operation in organic field effect transistors or solar cells, for

instance. Because the devices’ macroscopic properties arise from the materials’ molecular organization, a detailed understanding of the microscopic structure is essential for targeted developments. In order to shed light on the spatial orientation and order in thin films of P(NDI2OD-T2) the technique of Infrared Transition Moment Orientational Analysis (IR-TMOA) is employed. Therefore, the absorbance of structure-specific bands depending on the inclination of the sample and on the polarization of the IR light is evaluated. This enables to determine the tensor of absorption separately for the respective molecular moieties as well as to deduce the orientation of atomistic planes defined through the polymer subunits, relative to the substrate and hence relative to each other. We found that the solvent used for spin coating (chlorobenzene or a chloronaphthalene:xylene mixture) determines the alignment of the T2 part (either face on or edge on), whereas the NDI unit is not affected. On the other hand, the inclination of the NDI plane is well retained for diverse sample thicknesses in between nano- and micrometers.

Machine learning for quantum many-body systemsMichael R HushUniversity of New South Wales (UNSW), Australia

How to efficiently calculate the ground state of a quantum many-body system continues to be a challenge in computational condensed matter physics. We investigate using deep artificial neural nets, and other techniques from machine learning,

to find the ground state wavefunction and energy of a quantum many-body system. We use the artificial neural net to make an approximate representation of the wavefunction, and then use modified methods from quantum Monte Carlo to find the ground state of the system. We compare these methods to direct numerical evaluation of the system ground state, and investigate the scaling of accuracy and memory requirements as the system size increases. We apply these simulation methods to the study of stoichiometric rare earth ion crystals (SREI). SREI crystals have shown exceptional promise as a material for quantum memories. But are particularly challenging to simulate as they have disorder which is of comparable size to the interaction strength between ions. We investigate the ground states of these crystals under different optical driving strengths.

The Nucleation and Growth Mechanisms of Cubic Zirconia Condensed on Porous NiO – Cubic ZrO2 at Electron Beam – Physical Vapor Deposition Oleksandr Vasylyev1, Mykola Brychevskyi1, Yehor Brodnikovskyi1, Mariusz Andrzejczuk2, Maciej Spychalski21Frantcevych Institute for Problems of Materials Science, Ukraine 2Warsaw University of Technology, Poland

The dense helium impermeable cubic zirconia coating stabilized with 1-mol. % CeO2 and 10-mol. % Sc2O3 (1Ce10ScSZ) was deposited with electron beam – physical vapor deposition (EB-PVD) technique as solid electrolyte film on highly

(~40-50 %) porous NiO – ZrO2 substrate that is as anode electrode of solid oxide fuel cell. The structure of the transitional zone between a EB-PVD zirconia film and its porous NiO – ZrO2 substrate was studied using high resolution transmission and scanning electron microscopy and related techniques. The plausible condensation mechanisms of zirconia from its vapor phase onto zirconia and nickel oxide phases of the substrate were established. In general, the ZrO2 condensation occurs in two stages with two mechanisms of growth – planar and cellular – by analogy with the solidification of the liquid in metallic and geological samples. The nucleation of ZrO2 coating is structurally dependent, and being deposited on ZrO2 and NiO phases of the NiO – ZrO2 composite occurs with two different routes, which, summarily, may be determined as the "defective layer by defective layer" for ZrO2 case, and as isolated “islands” for NiO case. High density of the planar growth layers and the existence of the deposition affected zone that is clearly discerned as well as doping it with Ni are probably responsible for the increased elasticity modulus of the film areas bordering the anode – electrolyte interface. The differences found are probably the result of differences in the melting temperature of ZrO2 and NiO, and Zr and Ni affinities to oxygen as well as their different behavior under high vacuum.

The variation of properties of charge conductivity arising from structure nonuniformity and thermal perturbation in ice crystalPANG Xiao-Feng University of Electronic Science and Technology, P.R.China

The variations of property of charge conductivity under influences of structure nonuniformity and temperature of medium as well as an externally applied electric -field in ice crystal with damping have been numerically studied by fourth Runge-

Kutta method in our soliton model. The investigations show that the proton-soliton undertaken the conductivity is very robust against the structure disorder including the fluctuation of the force constant and nonuniformity in the sequence of masses and thermal perturbation arising from the temperature and damping effect of medium, its velocity of conductivity increases with increasing externally applied electric-field and with decreasing damping coefficient of medium, but the proton-soliton disperses only for quite great fluctuation of force constant and damping coefficient. In the meanwhile, the proton-soliton in ice crystals is thermally stable in the region of temperature of T . This result obtained here provides an evidence for the soliton excited in the ice crystal.

New Hybrid Bandgap Engineering: Rhombohedral Super-Hetero- Epitaxy TechnologySang H. ChoiNASA Langley Research Center, USA

Today’s trillion dollar semiconductor industry is based on two bandgap engineering crystal alloy models: cubic and hexagonal crystal structure constraints. Recently, a new rhombohedral super-hetero-epitaxy technology was developed as a world

first at NASA Langley Research Center. This newly discovered epitaxy technology enables the growth of unprecedented cubic-trigonal hybrid single crystal structure alloys with lattice match on Al2O3 substrates, hence with little strain and very few defects at the interface. As a result of this development, a new hybrid bandgap engineering model was generated allowing thousands of new semiconductor structures to be fabricated (see the figure below).

Promise of 2D MaterialsSaptarshi DasPennsylvania State University, USA

The interest in two dimensional (2D) materials is rapidly spreading across all scientific and engineering disciplines due to their exceptional properties, which not only provide a platform to investigate intriguing physical phenomena but

also promise solutions to the most relevant technological challenges. It is undisputed that silicon has been the DNA of our technological evolution for the last several decades. However, with the emergence of the era of Internet of Things (IoT), novel materials need to be mutated into the genetics of the modern technologies in order to meet the ever increasing demand of new functionalities. In this context, the 2D layered materials like MoS2, WSe2, Black Phosphorus, Graphene and many more find their application in flexible electronics, self-powered electronics, advance optoelectronics, neural electronics as well as digital electronics. In fact, field effect transistors, gas sensors, bio-detectors, mechanical resonators, optical modulators and energy harvesting devices with superior performances have already been demonstrated based on different 2D materials. A major challenge towards the commercialization of 2D materials is the large area, scalable and controllable growth of highly crystalline monolayers in a cost effective way. In this context, chemical vapor deposition, liquid phase exfoliation and electrochemical synthesis approaches are showing a lot of promise. My talk will provide a holistic understanding of 2D materials starting from energy efficient large area synthesis to ultra-low power device fabrication to different electronic and optoelectronic applications.

Theoretical evaluation of various physical parameters of metal hydroxides with brucite structure V. S. HarutyunyanYerevan State University, Armenia

Metal hydroxides are of a growing interest in electrochemical applications, environmental science, medicine, and technology of the cultural heritage restoration and conservation. For understanding of physicochemical properties and

effective practical applications of metal hydroxides, there are many reports in literature both on bulk and nano-scale properties of these compounds. It is of particular interest and importance to have for metal hydroxides the tabulated theoretical data for such important physical parameters that characterize the specifics of structure (the Madelung constant), the strength of bonding (bulk modulus and lattice energy), the thermodynamically stable morphology (surface energy at morphologically important surfaces), and the adsorptivity-controlling characteristics (near-surface electrostatic potential and field). Meanwhile, in literature, for metal hydroxides there is no complete theoretical data of above specified physical parameters.

This study is devoted to theoretical evaluation of the Madelung constant, elastic bulk modulus, lattice energy, surface energy, and near-surface electrostatic characteristics of metal hydroxides. The calculations are restricted to the case of metal hydroxides with brucite structure, M(OH)2 (M = Mg, Ca, Mn, Fe, Co, Ni, Cd). The evaluation of all above parameters is based on calculation of the corresponding lattice sums as in the case of calculation of the Madelung constant. The influence of the crystallographic size effect on these parameters is analyzed as well (transition from the bulk crystal limit to nano-sized particles). The obtained results are in a reasonable agreement with theoretical and experimental results available in literature.

Biexciton signatures in time-resolved photoluminescence of CdSe/CdS/ZnS quantum dotsI. I. Dobynde, V. I. Pavlenko and I. V. Beloussov Academy of Sciences of Moldova, Republic of Moldova

The use of time-resolved photoluminescense measurements has allowed us to resolve both spectral and temporal emission from short-lived biexcitons in the ensemble of CdSe/CdS/ZnS quantum dots, when only the ground state is occupied

by either one or two excitons. Due to the ‘‘forced’’ overlap of electronic wave functions and reduced dielectric screening, biexciton states are characterized by giant binding energies. The lifetime of biexcitons is significantly shorter than the radiative decay time; therefore, they cannot be detected in time-integrated photoluminescence spectra. The emission spectra of strongly confined neutral and charged biexcitons in CdSe quantum dots were registered earlier using time-resolved femtosecond photoluminescence measurements. In these spectra two biexcitons bands were observed. Leaving aside the study of the charged biexciton, we show that the separation of the spectra of highly overlapping exciton and neutral biexciton is possible under picosecond excitation of electron-hole pairs direct into 1Pe–1P3/2 state. Contrary to the earlier results, all fast Auger-like and intraband relaxation processes occur during the action of the exciting laser pulse, and the distribution of the number of electron-hole pairs in quantum dots does not follow Poisson’s law. We propose an elegant theoretical model. It is based on the introduction of auxiliary sources in the kinetic equations. The parameters of the sources are determined by fitting the solution of these equations that describes the full emission of the system to the experimental results obtained. Having found the parameters of the auxiliary sources we can determine the temporal dependence of the radiation from excitons and biexcitons separately.
