The Tufts University Department of Chemistry continues its dual mission of education and research.

RESEARCHCharles Sykes

In 1983 Heinrich Rohrer and Gerd Binningbecame the first to image individual atoms.Using a home-built apparatus floating on asuperconducting magnet and partially heldtogether with scotch tape they resolved theatoms of a silicon surface. They had just builtthe first Scanning Tunneling Microscope(STM). This instrument operates by scanning a very sharp metal tip biased at around 1 Voltover a conducting surface. With a separationbetween the tip and sample of around 1 nm one would expect classically that no current

should flow, but quantum mechanics tells us that electrons can tunnel from one place to another when the gap is small enough.The magnitude of this tunneling current is exponentially dependent on the distancebetween the tip and sample, and this phenomenon is the origin of the incredible resolution of the technique.

Over the last 25 years the design of STMs has been refined and the scanning probe field has reached the point where one can move single atoms and molecules,measure the vibrational spectrum of a singlebond, and even controllably alter the charge and conformation of individual molecules.The geometry of the microscope tip is crucial for high resolution imaging.

Chair’s CornerM A R Y S H U LT Z

Hello alums and friends of the

department. It has been another

great year for Chemistry at Tufts

University and we have even more

planned for the coming year.

Actually, part of the plans

involves you, our alums. A

Chemistry Alumni Organizing

Committee is being formed with

the initial contacts being Lynn

Batchelder, Roy Desrochers,

Cedric D'Hue and Mark Latina.

The Faculty liaison for the group

is Professor Albert Robbat. The

Organizing Committee will be run

by alumni for alumni.The primary

purpose of the Committee is to

organize events involving our

graduates at various venues

beginning with an event around

reunion weekend on campus this

spring. Professor Robbat is looking

for volunteers to join the four

initial contacts, so please email

him at [email protected]

and let him know of your interest

and suggestions.

Our major news this year is

moving into the newly renovated

east wing and the hiring of

Professor Charles Sykes. Professor

Sykes received his Masters

degree in Chemistry at Oxford

University in England and his

Ph.D. in Chemistry at Cambridge

University also in England. He is

a physical chemist working on

some very fundamental problems

in the field. Here at Tufts, Professor

Sykes is setting up experiments

at 4 K and will scan surfaces with

STM tips we prepared by electrochemicallyetching tungsten wire in concentrated potassiumhydroxide solution. Most of these tips yieldatomically resolved images, which means thatthe tips have a single atom protruding a fractionof a nanometer further than all the other atoms.

My interest in this technique arose during myPh.D. at Cambridge when I had the opportunityto use an STM, and I realized the incredibleopportunities this microscope offered in theunderstanding of chemistry at the single moleculelevel. My group is now focused on using STMto study catalytically relevant systems in anattempt to understand reaction mechanisms byrelating atomic-scale structure to reactivity. Weare also interested in the intrinsic properties ofmetals such as copper, silver and gold and howwe can exploit them in order to position, order,and move molecules with nanometer precision.

We can create regular surface features called“Quantum Corrals” which are single atom highterraces containing between 50-3000 atoms.Electrons are trapped inside these structures and

they form patterns as they bounce off the sidesof the corrals. Quantum mechanics allows us tocalculate the wavefunctions of the electronstrapped in these structures using simple particlein a box equations. The goals of this project areto understand how molecules interact with theelectron density in these systems and to investi-gate how we can tailor these interactions inorder to spontaneously self-assemble moleculesinto new surface architectures.

To date, my most interesting research involvedour discovery at Penn State that individualhydrogen atoms could be moved and positionedjust below a metal surface using the microscopetip. Figure 2 shows an STM image of the word“Sykes” I wrote by placing individual hydrogenatoms in subsurface sites in palladium metal.This type of work has important implications for the chemical and catalysis industries, as manyimportant hydrogenation reactions are thoughtto be driven by this subsurface hydrogen.

Professor Charles Sykes obtained a combinedB.S./M.S. in Chemistry from Oxford University(UK) in 1998 before moving to Cambridge University to start a Ph.D. with ProfessorRichard Lambert in Surface Chemistry. Aftergraduating from Cambridge in 2002 he movedto the US as a postdoctoral fellow in ProfessorPaul Weiss’s group at The Pennsylvania StateUniversity to work on low-temperature scanningtunneling microscopy. After two years at PSU he moved to The University of North Carolinaat Charlotte to work in the OptoelectronicsCenter and specialized in atomic forcemicroscopy research.

The goals of this project are to understand how moleculesinteract with the electron density in these systems

and to investigate how we can tailor these interactions in order to spontaneously

self-assemble molecules into new surface architectures.

Manipulation of hydrogen atoms beneath the

surface of palladium using low-temperature

STM produces features that are only 0.03 nm

high and 4 nm wide. These arise from the out-

ward distortion of the surface metal atoms to

accommodate the hydrogen atoms placed in

chemically and technologically important sites

immediately below the surface.

The Chemistry Department recently purchased a new gas chromatography/massspectrometry (GC/MS) instrument fromShimadzu Corporation. The GC hasstate-of-the-art temperature and pressurecontrol technology, while the MS providesunmatched detection sensitivity. The dataanalysis software uses automated searchablelibraries to identify sample unknowns. TheGC/MS will be used to support problem-based lab learning experiments in Chemistry42 (quantitative analysis), Chemistry 141(instrumental analysis), and in a universitysponsored freshman course, Windows onResearch, Environmental Forensics.

Coupling mass spectrometers to gas andliquid chromatography systems, the purposeof the latter is to separate componentspresent in complex mixtures into individualconstituents prior to detection, has madethis instrument the most often used analytical tool in industry. Sophisticated algorithms are used to match each samplecomponent’s mass spectrum against a knowncompound’s mass spectral fingerprint inthe library. When no spectral interferencesexist from other constituents in the sample,compound identification is unambiguous.

Experiments will be developed to teach students how to use GC/MS and LC/MS instruments, apply them to real-worldproblems and, at the same time, learn aboutthe science behind each of the techniques.In one experiment, students are given a soilsample contaminated with fuel and askedto determine the type (e.g., gasoline, dieselfuel, bunker oil, and/or coal tar) and age of contamination. A list of indicator compounds (biomarkers) is provided thatcan be used to differentiate fuel type andrelease age. Since these compounds rangefrom highly volatile (gasoline) to extremelylow volatility organics (coal tar), studentsneed to develop GC separation methodspractical to the boiling range of these compounds. To accomplish this task efficiently, students learn how to use a software tool that calculates optimum GC separation performance based on running extremely slow, faster, and fastestexperiments. From this data, studentslearn about the field of separation scienceby answering questions related to theoryand practice as they relate to why separation

efficiencies change with column temperatureand pressure conditions. Once each tech-nique has been optimized, students learnhow to use the MS library search tools toidentify sample unknowns. They learn, atthe same time, how mass spectrometers work and how to interpret MS data.

Students will have success, but will fail to identify some of the important indicator compounds because they existin low concentrations and are masked byinterferents in the sample. Fresh gasoline,for example, consists of more than 250 different organic compounds.

Failure to identify key constituents is an important problem in the chemicalindustry. The ability to identify unknownsin complex mixtures is equally important in the food, beverage, fragrance, and phar-maceutical industries, where unanticipatedodors, poor taste, or toxic compounds mayresult in unanticipated health problemsand/or damage to the brand. Concentratedoil extracts of lemons and oranges, for example, contain more than one-hundred different organic compounds as do petroleum products. How is it possible to identify low level unknowns in suchcomplicated mixtures? Students will learn

how to use new deconvolution softwaredeveloped at Tufts (Robbat) that is capable of untangling complicated mass spectra so that low-level target compounds and unknowns can be identified. In the process, students will learn about chemometrics (statistical analysis) and the emergence of these tools to solve complex analytical problems.

Problem-based lab learning employsstrategies that mix academic rigor withpractical, hands-on training. It offers students an opportunity to spend more time learning instruments and, at the same time, understanding the strengths and weaknesses of each technique in a particular application. Problem-based labexperiments are not “cook-book” as werelaboratory experiments done in the past.Roy Desrochers, a Tufts graduate and consultant in the beverage industry, hasalready offered to help with the design of a lab that will employ the MS as an electronic nose to “sniff ” differences in the aroma of beer. I welcome your involvement in helping to develop another problem-based lab experiment based on your experiences.

In Memoriam

It is with great sadness that we report on the passing of Grant Urry.Professor Urry was chairman of the department from 1968-1973 and was named the Robinson Professor of Chemistry in 1971,a chair he held until his retirement in 1992. Those of you who remember Professor Urry will appreciate the following:At his passing he requested no service, but rather to remember him by voting democratic.

Dr. Charles Sykes recentlyjoined the faculty as a physicalchemist. Charlie received hisMaster’s Degree in Chemistry at Oxford University in Englandand his Ph.D. in Chemistry atCambridge University in England. Prior to Tufts, Charlieworked as a research associateat University of North Carolina at Charlotte.

Justin Cronin is the most recentaddition to the office staff. Justinpreviously worked as a buyer atJoseph’s Gourmet Pasta & SaucesCompany. Justin majored ineconomics at the University ofMassachusetts.


Tufts Chemistry Journal ClubNick Yoder

For the past few years, a newarena for communicating anddiscussing scientific ideas hasbeen quietly growing in theChemistry Department. SinceSpring Semester of 2003, a fewgrad students have been organizing biweekly JournalClub meetings. Students, faculty,and postdocs gather to hearexciting, freshly publishedresults from the chemical literature presented by one oftheir own number. Althoughattendance was sometimeserratic in the beginning, thegroup is now firmly established in Department culture andattracts 15-20 attendees permeeting. An even surer sign ofthe original group’s success isthe establishment of a secondJournal Club with a different scientific focus in Spring 2005.(see accompanying article on the Physical/Analytical Journal Club)

The older group, known as theTufts Chemistry Journal Club,began as a group dedicated to discussing biologically oriented literature. The decisionto narrow the scientific topicswas not easy, but was intendedto keep the nascent groupgoing. Comments grad studentNick Yoder, one of the original organizers:“Our goal was to onlymeet every few weeks, but toattract a core group that attendsevery meeting. We felt that if thescience was too general, wemight not get that core.”Theplan has worked out well, and

the scientific focus has evenbroadened somewhat. Recentpresentations have addressedthe characterization of themolybdenum-iron cofactor of anitrogen-fixing enzyme, theacceleration of organic reactionsin combinations of immisciblesolvents and, in a guest lecturefrom Chemical Engineering’s Professor Blaine Pfeifer, the large-scale production of organic chemicals by bacteria.One particularly memorable discussion considered basic scientific philosophy and howbest to study complex biologicalsystems.

Each meeting focuses on a particular paper, which is distributed electronically theweek before the meeting.The presenter makes an informal presentation duringwhich audience questions areencouraged, and more discus-sion follows the end of the talk. Refreshments are provided,thanks to the kind support ofthe Department, the GraduateStudent Council, and the Graduate School of Arts and Sciences.

The Club provides many bene-fits. For starters, students getsome help keeping up with thefast pace of scientific researchand also benefit from havingfaculty to provide backgroundand insight.“The journal club isvery useful to follow currenttrends in science and, mostimportantly, talk about themwith people who are interestedin it” comments graduate student Ivan Korendovych.Beyond that, students get

some insight into how to keep up with literature andwhat constitutes an interestingpaper. They can also hone theirpresenting skills, a significantand under-emphasized part ofboth academic and industrial science. Many more studentshave realized this chance, as the number of volunteers ready to present has grownsteadily.

Beyond these, however, theJournal Club provides an

opportunity to get away from the daily grind of theirexperiments and consider exciting new research. As Professor Marc d’Alarcao says:“The intellectual environment of our department dependsheavily on events outside theclassroom and lab, includingseminars, journal clubs, and even the ‘problem of the day’posted in the graduate studentlounge. These extracurricularactivities provide a forum for all of us to take a break from

Physical Chemistry Journal ClubDan Killelea

Public speaking is one of the most important skills a chemist canpossess. No matter what aspect of chemistry a student enters afterleaving Tufts, it will be of utmost importance that graduates be able to communicate clearly to an audience. Public speaking skills are emphasized by the degree requirements; however, theopportunities to present are among the most stressful aspects ofthe graduate program!

The success of the biochemistry journal club inspired a group of students in the physical chemistry groups to start a comple-mentary journal club, the Physical Chemistry Journal Club (PCJC).Dan Killelea typically recruits speakers and with help from Irene Li and Tory Campbell gets refreshments, and sets up for the meetings. The meetings are held alternating Friday afternoons and are intended to be an informal forum for discussion of current research.

The PCJC gives the department a chance to step out of their specialty and look at a different problem.Topics covered over thepast year have included multiple quantum coherences of nuclearspins in a nanometer-scale device, sequence-specific molecularlithography on single DNA molecules and single-molecule optoelectronics. The PCJC looks forward to our second year, and a new slate of presentations from both faculty and students!

A list of past and future presenters can be found athttp://chem.tufts.edu/PhysChem.html. If you are interested in attending or presenting, please email Dan Killelea at [email protected].

Younger Chemists CommitteeIvan Korendovych

This year three of Tufts Chemistry graduate students,Ginevra Clark, Laila Dafik andDan Killelea were selected for a weeklong German ExchangeProgram. This program is anexchange program betweenthe German Chemical Society(GDCh-JCF) and the Northeast-ern Section of the AmericanChemical Society (NESACS)Younger Chemists Committee(YCC). Each year since the program's conception, a groupof twelve younger chemists has traveled across the AtlanticOcean to participate in a weeklong program.The programusually consists of visits to local laboratories, tours of local companies, presentationsat a regional student research conference, networking eventsand, of course, sightseeing.Foreign career and educationalopportunities are especiallyemphasized throughout theweek. The students that partici-pated in the program wereselected by a selection commit-tee in a highly competitive two-step process that consisted ofapplication screening followedby an interview.

CGSC News

The 2005-2006 members of

the CGSC (Timothy Blicharz,

Tory Campbell, Ryan

Hayman, Subrahmanian

Tarakkad Krishnaji, and

Deniz Yuksel) have been

busy organizing fun and

stimulating social events for

the department this year.

With the conclusion of the

Tufts Intramural Summer

Softball League, a cookout

was held to celebrate another playoff con-

tending Chemistry Department ‘Isotopes.’

The annual September rafting trip saw its

biggest turnout yet, with 16 people partici-

pating, including several from the incoming

first year graduate student class. Many first

year graduate students also took advantage

of the Q&A session sponsored by the CGSC

in October, where they could bring forth

questions regarding classes, choosing a

research group, or any other aspect of

graduate student life at Tufts. Plans for

the winter months include movie night

and other popular New England activities,

such as ice skating and skiing trips. Once

spring and summer roll around, there will

surely be more interesting and exciting

activities in store for the department, too!

and Dr. Blaine PfeiferIt seems that a good portion of the graduate students in

the chemistry department have been leading double lives.

Aside from their work in chemistry, they also seem to be

football players. A group of about 20 students meets on

Saturday mornings for a game of tag-football. The weather

does not stop the game. So far, they have played in bitter

cold, almost a foot of snow, and the infamous mud bowl on

an unseasonably warm January morning. Despite the rumors,

Bill Belichick and Rodney Harrison have not agreed to play,

at least not yet!

Continued from page 1 STM. The combination of STM

and low temperature produces

some stunning and compelling

images of electron waves and

molecules assembled on surfaces.

He is currently setting up his lab

on the ground floor of the newly

renovated east wing. The space

has certainly transformed with this

cutting edge instrumentation.

We also welcomed one of our

largest classes of graduate students

this fall – a full seventeen strong.

Graduate students are, in many

ways, the lifeblood of the depart-

ment and we welcome these new

recruits to our professional ranks.

Two graduate students: Nicholas

Yoder and Yina Kuang, received the

graduate student excellence award.

The award carries with it an expense

paid trip back to the graduate

student’s undergraduate school

where they present a seminar

about their research at Tufts.

This year we had our first winner

in the Gladys Anderson Emerson

Scholarship competition. Mimi Cho

received this award in recognition

of her outstanding performance,

including research, in chemistry.

The scholarship is sponsored by

Iota Sigma Pi (ISP).

On the faculty front, this year

we are searching for a lecturer in

chemistry. The lecturer will take

major responsibility for the main-

stream introductory program and

is expected to play an integral role

in ongoing efforts to ensure that

all students achieve their potential

in chemistry.

With the completion of the East

Wing renovation, only the center

of the building remains to complete

the phased renovation plan. The

center of the building houses the

organic chemistry teaching labora-

tory that many of you remember

well. We are looking to our alums

to help us renovate this space.
