Nature Research Journals•Publishes the most significant advances across the discipline each covers.

•Significance should be apparent to anyone in that discipline.

To communicate the world’s best and most important science to scientists across the world and to the wider community interested in science

Nature’s mission:

• Publishes the most significant advances with the widest implications.

• Significance should be readily apparent to anyone from any field.

What makes a Nature journal

• Highly selective — only a fraction of submissions are published.

• High impact.

• Each journal is run by a team of full-time, professional editors.

• Each journal is independent from each other journal — rejection from one doesn’t prejudice consideration by another.

China: Overhaul rules for hazardous chemicalsZhenwu Tang, North China Electric Power University 资源与环境研究所 唐阵武Qifei Huang & Yufei Yang, Chinese Research Academy of Environmental Sciences, Beijing, China.

Nature 525, 455 (24 September 2015); doi:10.1038/525455d; Published online 23 September 2015

Full text: The huge chemical explosion at the Chinese port of Tianjin on 12 August is another in the country’s long list of industrial accidents involving chemicals. In 2010–14, more than 2,000 people were killed in 326 such accidents (J. Ren and Y. Mu Chem. Enterp. Manag. 16, 28–31; 2015; in Chinese), calling into question the adequacy and enforcement of national regulations for the safe management of hazardous chemicals. China needs better legislation and more detailed regulations for controlling risk at different stages in the life cycle of hazardous chemicals. Safety supervision must be made more effective, for example by drawing up regulations modelled on the European Union’s Seveso Directive for industrial accidents (see go.nature. com/zyjp85). Supervision is currently disorderly, overseen by a fragmented and overlapping structure of multiple agencies, including the State Administration of Work Safety and the ministries of transport, public security, environmental protection, agriculture and health. Effective enforcement of China’s safety management of hazardous chemicals may be foiled by the limited expertise of company front-line managers (M. Liu et al. Contemp. Chem. Ind. 43, 2661–2662; 2014; in Chinese). More data are needed on the nature, handling and storage of the chemicals themselves so that risks can be properly assessed and managed (see go.nature.com/bzsydq).

Evaporation: Evaluate risks of coating reservoirs

Guohe Huang, North China Electric Power University 能源与环境研究中心主任 黄国和Yao Ya, University of Regina, Saskatchewan, Canada

Nature 520, 33 (02 April 2015); doi:10.1038/520033c; Published online 01 April 2015

Full text: The environmental effects of chemical films that reduce evaporation of water from reservoirs should be properly evaluated before the films are applied on a large scale (Nature 519, 18–19; 2015). For example, when these films are driven by waves towards the shoreline (F. R. Crow and A. L. Mitchell Water Resources Res. 11, 493–495; 1975), they could accumulate in soils and sediments and then enter biological concentration processes, disrupting ecosystems (C. Franke et al. Chemosphere 29, 1501–1514; 1994). The film coating reduces the water’s surface tension, interfering with floating plants, pollen transport and insect egg-laying. It has a heating effect that could alter flux between water layers, disturbing solutes and habitats. Hydrophobic airborne pollutants, including particles of black carbon, will be attracted to the films, potentially changing the surface’s reflectivity (albedo) and contributing to climate change. We should learn from previous ill-judged large-scale chemical applications and ensure that the necessary safety tests and regulatory measures are in place first.

Mesoporous TiO2 Yolk-Shell Microspheres for Dye-sensitized Solar Cells with a High Efficiency Exceeding 11%

Song-Yuan Dai, North China Electric Power University 可再生能源学院 戴松元Zhao-Qian Li, Wang-Chao Chen, Fu-Ling Guo, Li-E Mo, Lin-Hua Hu & Song-Yuan Dai, Hefei Institutes of Physical Science, Chinese Academy of Science

Scientific Reports 5, Article number: 14178 (2015); doi: 10.1038/srep14178; Published online 18 September 2015

Abstract: Yolk-shell TiO2 microspheres were synthesized via a one-pot template-free solvothermal method building on the aldol condensation reaction of acetylacetone. This unique structure shows superior light scattering ability resulting in power conversion efficiency as high as 11%. This work provided a new synthesis system for TiO2 microspheres from solid to hollow and a novel material platform for high performance solar cells.

Explosive or Continuous: Incoherent state determines the route to synchronization

Xia Huang, North China Electric Power University 数理学院 黄霞Can Xu, Jian Gao, Yuting Sun & Zhigang Zheng, Beijing Normal UniversityScientific Reports 5, Article number: 12039 (2015); doi: 10.1038/srep12039; Published online 10 July 2015

Abstract: Abrupt and continuous spontaneous emergence of collective synchronization of coupled oscillators have attracted much attention. In this paper, we propose a dynamical ensemble order parameter equation that enables us to grasp the essential low-dimensional dynamical mechanism of synchronization in networks of coupled oscillators. Different solutions of the dynamical ensemble order parameter equation build correspondences with diverse collective states, and different bifurcations reveal various transitions among these collective states. The structural relationship between the incoherent state and the synchronous state leads to different routes of transitions to synchronization, either continuous or discontinuous. The explosive synchronization is determined by the bistable state where the measure of each state and the critical points are obtained analytically by using the dynamical ensemble order parameter equation. Our method and results hold for heterogeneous networks with star graph motifs such as scale-free networks, and hence, provide an effective approach in understanding the routes to synchronization in more general complex networks.

A comparison of light-harvesting performance of silicon nanocones and nanowires for radial-junction solar cells

Yingfeng Li, Meicheng Li, Pengfei Fu, Ruike Li & Dandan Song, North China Electric Power University可再生能源学院 李英峰 李美成 付鹏飞 李瑞科 宋丹丹Meicheng Li, Chao Shen & Yan Zhao, Chongqing Materials Research InstituteScientific Reports 5, Article number: 11532 (2015); doi: 10.1038/srep11532; Published online 26 June 2015

Abstract: Silicon nanorod based radial-junction solar cells are competitive alternatives to traditional planar silicon solar cells. In various silicon nanorods, nanocone is always considered to be better than nanowire in light-absorption. Nevertheless, we find that this notion isn’t absolutely correct. Silicon nanocone is indeed significantly superior over nanowire in light-concentration due to its continuous diameters, and thus resonant wavelengths excited. However, the concentrated light can’t be effectively absorbed and converted to photogenerated carriers, since its propagation path in silicon nanocone is shorter than that in nanowire. The results provide critical clues for the design of silicon nanorod based radial-junction solar cells.

Ordering Ag nanowire arrays by spontaneous spreading of volatile droplet on solid surface

Han Dai, Ruiqiang Ding, Meicheng Li, Yingfeng Li & Mwenya Trevor, North China Electric Power University丁瑞强 李美成 李英峰Jinjer Huang, Harbin University of Science and TechnologyScientific Reports 4, Article number: 6742 (2014); doi: 10.1038/srep06742; Published online 23 October 2014

Abstract: Large-area Ag nanowires are ordered by spontaneous spreading of volatile droplet on a wettable solid surface. Compared with other nanowires orientation methods, radial shaped oriented Ag nanowires in a large ring region are obtained in an extremely short time. Furthermore, the radial shaped oriented Ag nanowires are transferred and aligned into one direction. Based on the hydrodynamics, the coactions among the microfluid, gravity effect and the adhesion of substrate on the orientation of the Ag nanowires are clearly revealed. This spreading method opens an efficient way for extreme economic, efficient and “green” way for commercial producing ordered nanowire arrays.

High performance polymer solar cells with as-prepared zirconium acetylacetonate film as cathode buffer layer

Zhan'ao Tan, Shusheng Li, Fuzhi Wang, Deping Qian & Jun Lin, North China Electric Power University 可再生能源学院 谭占鳌 林俊Jianhui Hou & Yongfang Li, Institute of Chemistry, Chinese Academy of SciencesScientific Reports 4, Article number: 4691 (2014); doi: 10.1038/srep04691; Published online 15 April 2014

Abstract: Low-work-function active metals are commonly used as cathode in polymer solar cells (PSCs), but sensitivity of the active metals towards moisture and oxygen results in poor stability of the devices. Therefore, solution-proceessable and stable cathode buffer layer is of great importance for the application of PSCs. Here we demonstrate high performance PSCs by employing as-prepared zirconium acetylacetonate (a-ZrAcac) film spin-cast from its ethanol solution as cathode buffer layer. The PSCs based on a low bandgap polymer PBDTBDD as donor and PC60BM as acceptor with a-ZrAcac/Al cathode demonstrated an average power conversion efficiency (PCE) of 8.75% which is significantly improved than that of the devices with traditional Ca/Al cathode. The improved photovoltaic performance is benefitted from the decreased series resistance and enhanced light harvest of the PSCs with the a-ZrAcac/Al cathode. The results indicate that a-ZrAcac is a promising high performance cathode buffer layer for fabricating large area flexible PSCs.
