Physical Chemistry, Analytical Chemistry, Surface Science, Materials Science, and Environmental Science
The focus of my research program is experimental studies of chemical and physical phenomena at aqueous interfaces. While most of the current knowledge of interfacial physics and chemistry comes from experiments with well defined, static interfaces, a large number of important chemical phenomena occur at surfaces of molecular solids under conditions where such surfaces are dynamic, disordered, and difficult to characterize. A vivid example of such a dynamic interface is the surface of ice at temperatures near 0 ºC. In addition to serving as an excellent model for studies of general properties of molecular solid, ice is also ubiquitous in nature and, therefore, is of great interest for Environmental Science. Over the past four years we have developed of complex research apparatus in our laboratory at the GW. This unique scientific instrument combines such typical high vacuum techniques as Time-of-Flight Mass Spectrometry and Thermal Desorption Spectroscopy with Ultrafast Microcalorimetry and makes it possible to study desorption, phase transitions, transport phenomena, and reactions in thin (1-2 micrometer) vapor-deposited ice films at temperatures up to 00C. Because of the critical role of ice particles in the atmosphere, the results of these experiments are of great interest to environmental chemistry and studies of climate.
