Chemistry of interfaces and surfaces play a key role in understanding a number of diverse phenomena from wetting, heterogeneous catalysis, biosensing, atmospheric chemical reactions, electrochemical processes and nanoparticle behaviour. Such studies play an important role in properly addressing issues of worldwide relevance. Our department has long-standing research efforts in these areas, including programs to develop better and more efficient fuel cells, provide more effective approaches to extracting feedstocks from oilsands, identify and define atmospheric processes that may pose environmental risk, and generate new approaches to detection of trace species.
