Prof. Rory Waterman receives an NSF award for a new X-ray diffractometer
Prof. Rory Waterman was awarded about $300,000 to purchase a new X-ray diffractometer (XRD) from the National Science Foundation (NSF). The award comes from the Major Research Instrumentation (MRI) grant program at the NSF through the Division of Chemistry. The award is to support the research of Prof. Waterman, other professors and students in Chemistry and in other departments on campus (e.g. Geology and Physics) who have a demonstrated need for a single crystal XRD to collect structural data on crystalline solids at UVM for the first time in more than a decade.
The photo shows Prof. Waterman standing next to the Bruker Smart Apex II XRD instrument that was installed early summer 2011. Since the instrument was installed several UVM research groups as well as collaborations off campus has already been collected a myriad of crystal structure data, and the first publications with data from the new instrument having already been submitted.
A diffractometer provides students a direct link between the physical phenomena students learn in the class room (here, the interaction of light and solids) to determine molecular structure. X-ray diffraction is an ideal technique to visualize molecules, and a number of graduate and undergraduate students are already using this instrument to do exactly that.
Matthias Brewer is promoted to Associate Professor of Chemistry and awarded tenure
Matthias Brewer, Ph.D., arrived at UVM in the fall of 2005 to begin his career as an Assistant Professor of Chemistry. In May 2011, he was promoted to Associate Professor of Chemistry and awarded tenure. Prof. Brewer has been a rising star in the Department of Chemistry (see his research page) and has increased the profile of UVM Chemistry nationally.
Prof. William E. Geiger, Jr. will become Emeritus Professor of Chemistry after the May 22nd, 2011 UVM Commencement
“When Camus said ‘To think is to re-think,’ he was not likely to be reflecting on a chemistry professorship. But his thought describes the challenge and the wonder of preparing course material, considering research pathways, and learning of new experimental results by one’s students and colleagues. It is a gift to have a profession that is also a dear hobby.”
—William E. Geiger, Jr.
Prof. Bill Geiger who is also the Pomeroy Professor of Chemistry began at UVM in 1974 and has had a long and illustrious career. He will become an Emeritus Professor, but will not retire. Bill will continue his research and supervise his graduate students and postdoctoral fellow through his continued funding by the National Science Foundation (NSF). Bill will also continue to teach our key CHEM 202 Advanced Chemistry Laboratory course for chemistry majors offered every fall. If you visit the Department of Chemistry, please stop by to see Bill in his office and laboratory.
See the UVM Commencement website for details about Prof. Geiger
Proclamation read at the May 22nd, 2011 UVM Commencement:
William E. Geiger, Jr., you arrived in Vermont in 1974 after receiving your Ph.D. from Cornell University and serving as an assistant professor at Southern Illinois University. Your internationally recognized scholarship in Analytical and Inorganic Chemistry and your continuous contributions to the teaching and service missions of the university resulted in your appointment as the Pomeroy Professor of Chemistry in 1997. You are in continual demand as a lecturer having given over 150 presentations at professional meetings and at other institutions. You have been a visiting faculty member at institutions in the United States, United Kingdom, France, Germany, New Zealand and South Africa. Your many graduate students and post doctoral research associates have gone on to distinguished careers in both academia and the private sector at home and abroad.
Your research, while varied, has always centered on the most fundamental question of chemical reactivity, electron transfer. You have developed and brought to bear several forefront techniques and approaches to these studies, and your pioneering methodologies have been adopted by many laboratories worldwide. This work, which has received continuous support from the National Science Foundation, has resulted in over two hundred peer reviewed publications, many of which are foundational documents in the field. One publication has been cited over one thousand times in the chemical literature.
You are a person of the highest intellectual and personal standards, a generous collaborator, a caring and dedicated teacher, and a colleague whom one can trust to always put the good of the department and the university above any short-term gains for yourself. The university is a better place thanks to your presence and contributions. You deserve and have our respect, gratitude and affection.
—proclamation written by Emeritus Professor of Chemistry Christopher W. Allen

Prof. Matthews publishes Volume 5 of the Encyclopedia of Mass Spectrometry: Elemental and Isotope Ratio Mass Spectrometry
Prof. Dwight Matthews and Prof. Diane Beauchemin (Queen' University, Kingston, Canada) have completed and published the 5th volume of the Encyclopedia of Mass Spectrometry. The Encyclopedia is a ten-volume project by the series editors Prof. Michael Gross (Washington Univ. in St. Louis) and Prof. Richard Caprioli (Vanderbilt Univ.) to produce an exhaustive set of information on mass spectrometry.
Volume 5 is devoted to elemental and isotope ratio mass spectrometry, is 1,088 pages, contains fourteen chapters and 97 contributions by a range of authors, including the volume editors, Profs. Beauchemin and Matthews.
Volume 5 of the Encyclopedia of Mass Spectrometry can be purchased directly from the publisher, Elsevier, or from Amazon and focuses on (1) the plethora of atomic ionization techniques that have been coupled to MS for elemental analysis, the measurement of isotope ratios, and even the determination of inorganic compounds and (2) the precise measurement of isotope ratios of organic elements as small gas molecules by isotope ratio mass spectrometry (IRMS).
Chapter 1 contains a description of inductively coupled plasma (ICP) MS, its requirements for sample preparation and introduction. The chapter also covers argon ICP, ion extraction, various mass analyzers, and the numerous application areas including environmental, geochemical, biomedical, nuclear, semiconductor, and speciation. Other atomic sources include the microwave plasma, which can be used as either an atomic ionization source or as a soft molecular ionization source, flames, spark sources, and glow discharges, including the types of mass spectrometers and separation approaches to which interfaces can be made.
Chapter 2 discusses the application of electrospray ionization MS to inorganic analysis. Secondary ion and neutral MS (Chapter 3) can be used to determine trace elements in solids, particularly on their surface, with high spatial resolution. Atmospheric aerosols can also be studied using laser(s) for desorption and ionization of analytes in solids (Chapter 4). Thermal ionization MS, where sample atoms or molecules are ionized as they evaporate from the surface of a hot filament, is the focus of Chapter 5. Special applications are in Chapter 6, which covers accelerator MS, and Chapter 7, where large calutrons can be contrasted to the small analyzers that are taken aboard spacecraft, for example.
Chapter 8 focuses on IRMS for precise isotope ratio measurements. The highest level of precision can only be accomplished through use of a mass spectrometer specifically designed for the purpose of making differential measurements. A key advance is direct conversion of organic compounds into small gas molecules for measurement, leading to important uses ranging from geology to biomedical sciences.
