Our research activities involve the investigation of electrochemical systems of interest in biochemical redox processes , in energy conversion such as solar to electrical energy ( electrochemical solar cells ) , chemical to electrical energy ( fuel cells), and electrical to chemical energy ( electrosynthesis), and in molecular electronics such as molecules bound to Ag or Au metal clusters.
Electrochemical electron transfer reactions are unique ways to make novel chemical species and to modify metal surfaces with adsorbed layers with unusual properties, e.g., layers of conducting polymers . We investigate the structure and dynamics of adsorbed molecules on metal surfaces using the insitu technique of surface enhanced Raman spectroscopy (SERS). To further this end, we have developed unique single scan and pump-probe time-resolved SERS (TRSERS) methods to investigate transient structural changes for adsorbed molecules undergoing molecular change in the nanosecond, microsecond, and millisecond time domain after an electrode potential pulse or a laser light pulse. Our studies have shown that it is possible to obtain detailed mechanistic information about the structure and dynamics of reacting molecules on metal surfaces. We are also using ab initio molecular orbital calculations to study the properties of individual molecules and of metal cluster/molecule systems.
Another area of interest is in the redox and complexation reactions which take place at the active sites of enzymes, especially those enzymes which contain iron porphyrins and vitamin B12 compounds as prosthetic groups. Our investigations in this area involves the study of the redox and ligand binding reactions of vitamin B12 (cobalamin) compounds in solution and at the active site of vitamin B12 dependent enzymes using Raman and electrochemical techniques. We are especially interested in the reactions of nitric oxide and nitrous oxide with these cobalamin systems. The in vitro studies are designed to help understand reactions which occur at the active site of the enzyme- methionine synthase , which has a methyl-B12 cofactor. We are also using electronic structure calculations to model cobalamin reactions in these enzymes.
