Abstract:Magnetic resonance spectroscopy has been intimately intertwined with fundamentaldevelopments in physics and chemistry during the last century. Without a doubt, NMRspectroscopy is nowadays a major analytical tool for chemists. There are few, if any, majorchemistry research centers that do not own and operate some sort of NMR facility or seekto have magnetic resonance spectroscopy available to their scientists. Yet, the origins ofmagnetic resonance are far removed from the routine analysis of materials arising fromchemical reactions, with which most chemists now associate this technique. Indeed, mag-netic resonance today is far more than simple analysis of materials; it is a lively, evolvingfield of study even sixty years after its discovery.The history of magnetic resonance shows the influence of war, of philosophical upheavalthat resulted in the development of the quantum theory of the world, of petty disagree-ments, of work on teams and in isolation, of the influence of government programs, andof the tug of commercialization of scientific work. In short, it mirrors many pivotal fac-tors that influence a wide variety of endeavors in science.In this history stand the people of magnetic resonance – spectroscopists who have spenttheir lives studying how spins whirl in their unending dance. I shall discuss various con-tributions, including those of scientists at the University of Delaware with whom I havehad the pleasure to associate over the years, which will hopefully put the efforts of mag-netic resonance spectroscopists into the larger context of the flow of ideas and develop-ments that characterized a time of seemingly limitless curiosity and boundless enthusiasmabout physics and chemistry.

UD Chemists Set World RecordChemists from the University of Delawareand coworkers have set a new world recordfor the shortest chemical bond everrecorded between two metals, break-ing a previous chemical record that stoodfor nearly 30 years. The record-breakingmetal-metal bond was achieved by form-ing multiple bonds between two atoms ofchromium. In this latest multiple-bond-ing advance, graduate student Kevin A.Kreisel and chemistry professor KlausH. Theopold of the University of

Delaware and coworkers synthesized a new type of quintuple-bonded dichromium complex,one that surpasses all known compounds for having the shortest measured metal-metal bondlength (J. Am. Chem. Soc., DOI: 10.1021/ja076356t).

In the complex, each chromium atom is coordinated to two nitrogenatoms, one each from two bridging diazadiene ligands containingdiisopropylphenyl groups. The result is a tight Cr2N4 core structure.The most noticeable feature is the very short 1.8028-Å Cr–Cr bond,which is the shortest metal-metal distance reported to date for anisolable compound. In collaboration with Clark R. Landis of theUniversity of Wisconsin, Madison, the researchers supported theirexperimental observations with calculations to confirm the bondingand electronic structure of the complex, including a bond order of 4.28.

Before the UD discovery, the previous record for the shortest metal-metal bond was 1.828-Å,achieved by F. Albert Cotton and coworkers at Texas A&M University in 1978 with a quadruple-bonded dichromium complex (Inorg. Chem. 1978, 17, 2084).

The Delaware Section of the American Chemical Society congratulates Dr. Theopold and hiscoworkers on this historic chemical achievement!

Chemistry students get unique opportunity to interview scientistsLeigh E. Thompson, Science Department, Tower Hill School, Delaware

During National Chemistry Week, chemistry students from Tower Hill School had theunique opportunity to interview scientists from the area to incorporate the theme, “TheMany Faces of Chemistry.” Over fifty scientists from AstraZeneca, DuPont, Agilent, TheUniversity of Delaware, and Colonial Metals participated in the project. The underlyingthemes of team work, communication, and pursuing an enjoyable career were prevalent ineach of the interviews. The students learned how chemistry is used on a daily basis, andthey gained valuable insight into possible careers they had not considered. I would like toextend a special thanks to all the scientists who participated in this project. It was certainlya valuable experience for my students.

CHEMVETSCHEMVETSTOPIC:

SPEAKER: Dr. Parry Norling

DATE: Tuesday, January 22, 2008

PLACE: DuPont, Chestnut Run

TIME: 12:00 Lunch (Admin. Bldg.)1:00 Lecture (Bldg. 713 auditorium)

INFORMATION:George Parshall (658-2066)

BIOGRAPHY:Dr. Parry Norling retired as an R&D planning director at DuPont. He then served as Chair-man of the Industrial Research Institute. Parry has also been an AAAS Fellow at RANDCorporation's Science and Technology Policy Institute and an adjunct visiting professor atGeorgetown University. He is currently a Visiting Fellow at the Chemical Heritage Foun-dation, a convener of Delaware Dialogues on science, ethics, and religion, and an instruc-tor at the Academy of Life Long Learning. Recently he spoke on “In Innovation isPatience a Virtue?” at the YKI’s (Institute for Surface Chemistry’s) 2007 Member Days inStockholm. His chapter “Insights for R&D Managers” was included in Innovation, Sci-ence, and Institutional Change, Oxford University Press 2006.

ABSTRACT:Dr, Norling will discuss some aspects of Science and Religion:• To what extent is each of our theologies, religious beliefs, or worldviews being shaped

as scientific discoveries change our understanding of our world?• Will some discoveries destroy religious faith?• Do some discoveries neglect or dismiss the spirit?• Can new discoveries undermine or support human morality?• Will science turn out to be inadequate and arrogant in its limited picture of what

is true?• Can it be said that “evolution has hardwired mankind for a belief in or yearning for a

higher power and in turn that belief leads to a disbelief in evolution”?

He will draw from talks and presentations in the Delaware Dialogues on Science Ethicsand Religion series (www.cil-de.org), which has been supported in part by the MetanexusInstitute. The discussion may touch upon: Evolution vs. Intelligent Design, Stem Cells, theunholy alliance of Medical practice and Religion, neuroscience and the soul, Daoism andthe parallels with modern science, and spirituality and health

NEXT MEETING:Tuesday, February 19, 2008. George Parshall will speak on “The Dilemma of DualUse Chemicals.”

COMBINED MEETINGProcess Spectroscopy Topical Group/Society for Applied Spectroscopy

From Miniaturized Infrared Sensors to Multifunctional Scanning Probes:Combined Techniques for Enhanced Information

Boris Mizaikoff and Christine Kranz, Georgia Institute of Technology

Date: Friday, February 1, 11:30-2:00; presentation begins at 12:15 PM

Location: Agilent Little Falls Site, 2850 Centerville Rd., Wilmington, DE

Cost: We will use the Agilent cafeteria – typical lunches cost $5-10

Reservations/questions: Call Lois Weyer at 410-392-1273 or email: [email protected]. We need to have guestnames by close of business Thursday, January 31.

AbstractOptical chemical sensor technology in the mid-infrared (MIR) spectral range (3-20 µm) is gaining importancein process monitoring, environmental analysis, security/surveillance applications, and the biomedical field, dueto the increasing demand for robust sensor technology with inherent molecular specificity. Interfacing IR-trans-ducers with continuous measurement situations in the gas and liquid phase becomes increasingly feasible withthe advent of appropriate waveguide technology (e.g., MIR transparent optical fibers and planar waveguides),protective surface coatings (e.g. diamond-like carbon, sol-gels, polymers, etc.), and the availability of advancedlight sources such as room-temperature operated quantum cascade lasers (QCLs) leading to miniaturized IRdiagnostics. Selected examples will highlight recent advances in miniaturizing IR sensor technologies alongwith application examples including extreme environments (e.g., deep sea), and biomedical analysis (e.g., in-vivo surgical monitoring). Recent developments in scanning probe microscopy (SPM) are focusing on the combination of individual SPMtechniques, or on the combination with optical techniques to expand the information content accessible at thenanoscale. In particular, combined AFM-SECM (Atomic Force-Scanning Electrochemical Microscopy) probeshave gained considerable interest for simultaneously providing topographical and laterally resolved electro-chemical information during AFM imaging. Combined SPM probes with an electroactive area integrated intothe AFM probe enable applying a potential to the integrated electrode and recording Faradaic currents resultingfrom electroactive surface processes, such as e.g., corrosion or biological redox activity. These processes can be(electro)chemically detected with spatial resolution, and directly correlated to the topographical informationobtained by the AFM measurement.Consequently, the next-generation of multi-functional analytical platforms ideally combines the benefits of scan-ning probe techniques, electrochemistry, and IR spectroscopy into a unique analytical tool, which will be dis-cussed for the first combination of MIR attenuated total reflection (ATR) spectroscopy with AFM enabling mon-itoring the sample topology at nanometer scales, while simultaneously probing bulk spectroscopic properties.

BiographiesDr. Boris Mizaikoff received his Ph.D. in Analytical Chemistry at the Vienna University of Technology in 1996.Since fall 2000 he has been a faculty member at the Georgia Institute of Technology, School of Chemistry andBiochemistry, heading the Applied Sensors Laboratory (ASL). Today, his research interests focus on opticalsensors, biosensors and biomimetic sensors operating in the mid-infrared spectral range, novel IR light sources(e.g. quantum cascade lasers), system miniaturization and integration based on micro- and nanofabrication,multifunctional scanning nanoprobes (e.g. combination AFM-SECM, NSOM-SECM), scanning probe tip inte-grated nano(bio)sensors, focused ion beam techniques, development of chemical recognition layers for separa-tion and sensing applications (e.g. molecularly templated materials, functionalized sol-gels), chemometric dataevaluation, advanced vibrational spectroscopic techniques including SEIRA and SERS, environmental analyti-cal chemistry, process analytical chemistry, and biomedical diagnostics. Dr. Christine Kranz received her M.S. and Ph.D. degrees in chemistry from Ludwig-Maximilians University inMunich (1992) and Technical University of Munich (1996), Munich, Germany, respectively. After spending ayear as a postdoctoral fellow at Vienna University of Technology, Institute of Analytical Chemistry (Austria),she accepted a position at the School of Chemistry and Biochemistry, Georgia Institute of Technology, Atlanta,where she is currently appointed as senior research scientist.

Another Year Already?Another Year Already?Al Denio, Section Councilor

National Chemistry Week Open HouseWe held this annual outreach event on

November 10 at The Independence School.As President of the Delaware Academy ofChemical Sciences, I organized a displaytable on DuPont’s super strong fiberKevlar. This is the fiber used in bulletproofgarments used to protect our police andmilitary members. It is truly a life savingproduct of DuPont research.The basic discovery was made by

Stephanie L. Kwolek at the PioneeringResearch Laboratory of the Textile FibersDepartment at the Experimental Station.After this event in 1965, it took anotherfive years and the work of many chemistsand engineers before Kevlar was availablecommercially.I called Stephanie and asked if she

would help at our table from noon until 3pm. She graciously agreed to come. Infact, she was the “star of the show.” Shebrought some Kevlar fabric which was cutinto small swatches and then autographedusing a felt-tip pen. This was provided toyoung people along with a single pagehandout on Kevlar.Norm Henry, our Vice President, assist-

ed Stephanie by preparing the fabricswatches. Martha Hollomon arranged forthe loan of a Kevlar vest and Solito Sumu-long provided some Kevlar gloves.Most of the young students who visited

our Kevlar table were in awe to meet thewoman whose great discovery is savinglives every day. I wonder how many ofthese students will be the chemists oftomorrow.

Save The DateThe Delaware Academy of Chemical

Sciences will hold “The Three LegendsLuncheon” on April 3 at the DuPont Coun-try Club. All three “legends” are fromDuPont’s former Textile Fibers Departmentof the last century: Stephanie L. Kwolek,Joe Labovsky and Russ Peterson. Detailswill follow soon.

ACS Government Affairs Committee SummitMartha Hollomon and I represented the

Delaware Section at this event on Novem-ber 12 and 13 in Washington. She alsogave a presentation as part of the trainingprogram. On the 13th we were paired witha member from Michigan and another fromSouth Carolina for a series of visits tooffices in the House and Senate. Ourschedule included the offices of SenatorsBiden, Carper and DeMint (S. Carolina)plus Representatives Castle, Upton (Michi-gan) and Inglis (S. Carolina).We urged support of “robust funding

measures” for NSF, NIST, DOE Scienceand NSF’s educational programs. I’d liketo think we made a favorable impressionbut time will tell.In February we have our annual “Contact

Congress Week” when I organize visits tothe offices of Biden, Carper and Castle.Please contact me if you would like to par-ticipate.

Chemistry and Falling LeavesAs I write this in late November, I pon-

der the problem of falling leaves and myefforts to remove them from our lawn. Yes,the exercise (work) is good for me but myback hurts. We need to quickly solve theproblem of converting this cellulosic mat-ter into ethanol. The leaves in our yard,with the proper chemistry, could make fora hell of a party. I’d prefer a still in our yardrather than a compost pile.

Thank YouMy thanks go to Narmada, John, Sujata,

Josh and Bill for a good 2007 for theDelaware Section, and to all the others whohelped in a variety of ways with our pro-grams and special events. Good luck toSujata as she leads us into the New Year. Ihope to see you all at the January meeting.
