Quantum/classical mechanics with applications to nanostructures, clusters, complexes and compounds

In computational chemistry, my research focus is on the chemical and physical properties of metallic nanostructures, clusters, complexes and compounds. In particular, I am interested in gold and silver nanorods and clusters that have unusual geometries or stabilities. These species may be bare metal atoms or, because the metal-sulphur bond is strong, they may be protected by sulphur-containing molecules. Some of these species have special optoelectronic properties and could be used as components of nanostructured devices. I also do calculations on complexes of mercury and arsenic which, due to their toxicity, are of interest in environmental chemistry. The mercury species are modeled under conditions approximating flue gases in coal-fired power plants while the arsenic species are modeled under conditions approximating aqueous solution. I plan to do calculations for hydrogen-bonded complexes of arsenic species with water molecules. I also plan to do calculations on hydrogen-bonded or proton-transfer complexes of interest in atmospheric chemistry.
