César Augusto Correia de Sequeira was born in Peso da Régua, Portugal, in 1943. On graduation in Chemical Engineering from the Technical University of Lisbon in 1968, he joined the staff of Instituto Superior Técnico as lecturer of Electrochemistry, Electrometallurgy and Electrothermy. In 1971 he started high temperature chemistry research in the Nuffield Research Group at Imperial College, obtaining a PhD from London University in October 1974. In the same year he returned to Lisbon and joined the University teaching staff, where he has been teaching and supervising research for more than 30 years. He spent one year (1982) with the Materials Development Division of the Atomic Energy Research Establishment (Harwell, U.K.), where he performed a fruitful research work on the development of all solid state polymer- based rechargeable lithium cells. He spent another year (1985-86) at the University of Utah, where he joined the research group of Prof. J. Janata on ion selective field effect transistors. He has directed several international projects on electrochemistry of hot corrosion, microbial corrosion, metal extraction, conducting polymers, energy storage and conversion. He is author/co-author of over 200 technical papers, editor/ co-editor of 12 books, a frequent lecturer or panellist at scientific meetings, and is a Fellow of the Institute of Materials (U.K.), a Fellow of the Institute of Corrosion (U.K.), an Active Member of the Electrochemical Society (U.S.A.), a Founder Member of the Portuguese Electrochemical Society, the Portuguese Materials Society, and the Moscow International Energy Club. His present research interests include electrical and electrochemical properties of nanomaterials, hydrogen production and storage, and low temperature fuel cells.
