Biography

Janusz Nowotny earned his Ph.D. in solid state chemistry at the Institute of Physical Chemistry, Polish Academy of Sciences, 1967, and obtained Sc.D. degree (habilitation) from the AGH University of Science and Technology, Krakow, in materials science. His research is focused on mass and charge transport in ionic solids. His work aims at the development of photosensitive oxide semiconductors for solar energy conversion and electrochemical gas sensors. He has been visiting professor at University of Bourgogne, Max-Planck-Institute for Solid State Research, University of Nancy, University of Marseille and Tokyo Institute of Technology. He obtained the US NSF award to support a major international project on oxide semiconductors (1974-78) and was a research coordinator of the international project on zirconia supported by the New Energy Development Organization, NEDO (1994-97). He was the director of NATO Advanced Research Workshop on Nonstoichiometric Compounds, 1988. He received the award of the International Association for Hydrogen Energy, 2008, for outstanding research contributions in the development of TiO2-based systems for solar hydrogen production. He published over 460 refereed papers and 17 books in the area of solid state electrochemistry
