Professor Richard Lambert

In September 2010 I moved my research laboratory to the University of Seville, where I spend half my time at fortnightly intervals. Current research includes development of new heterogeneously-catalyzed routes relevant to organic synthesis especially with respect to the production of fine chemicals and pharmaceuticals. Energy-related applications of catalysis, including high temperature fuel cells. Molecular self-assembly, chiral systems and enantioselective catalysis. Plasma-driven catalysis, nanoarchitectures for sensing and catalytic applications. New materials for hydrogen storage. Studies of high-energy helium and hydrogen ion implantation in alloys relevant to the operation of thermonuclear reactors. A wide range of experimental conditions are used ranging from single crystal surfaces in ultra high vacuum to nanoparticle systems in liquids under high pressure. Some of these projects involve collaboration with professors Steve Ley and Dominic Wright in Cambridge.
