My interrelated research interests are interdisciplinary studies of corrosion, electrochemistry and surface science. Necessarilly, we investigate materials at the nano scale, and develop methods for production of nano-materials. My research activities involve both fundamental studies of phenomena related to development of designed new materials, electrochemical conversions, and development research directed to providing solutions to problems of significance to power generation, natural resource conversion and transportation industries. Solid oxide fuel cells (SOFC) require stable and active electrodes, and stable and conductive electrolytes. We invented several such materials, which enabled development of SOFC for use of non-conventional fuels such as H2S and industrial syngas (H2, CO, plus smaller amounts of contaminants). These new materials and processes enable economic use of what is otherwise considered waste or pollution. Thus these technologies are very “green” in their applications. We are developing new technology for manufacture of ethylene and electrical power, more selectively than present processes. A series of new batteries is being developed that proffer high-power density and stable performance. We investigate electrochemical behaviour of materials, develop models and apply them in design of materials for power generation, e.g. nuclear plants, to reduce stress corrosion cracking of materials. We create protocols to reduce costs and improve safety of Canadian industries. We also develop new surface modification methods for biomaterials such as dental implants and joint replacement structures, to improve their biocompatibility.
