Biography

Janusz Nowotny is a professor of solar energy technologies at the University of Western Sydney. He has been a recipient of the Sir William Grove Award of the International Association for Hydrogen Energy and the Pfeil Award of the Institute of Materials, Minerals and Mining in London. Dr. Nowotny was the director of a NATO Advanced Research Workshop on Nonstoichiometric Compounds — Surfaces, Grain Boundaries and Structural Defects. He was also the founder and co-organizer of two series of International Workshops: Nonstoichiometric Compounds and Ceramic Interfaces.

… first comprehensive view on all the diverse properties of this material. … It is of invaluable importance for the entire materials science community. The book may be used as textbook for academic classes and researchers interested in the application of titania and titania-based materials. … The readers may find a wide range of materials data on mass and charge transport kinetics, segregation as well as a wide range of alternative defect-related properties of TiO₂. Since assignable problems are given for each chapter, the book is also very useful for graduate classes in Materials Science and Engineering. It is a must for a wide community of researchers and developers.
—Werner Weppner, International Journal of Hydrogen Energy 37, 2012

The present book provides a comprehensive survey of defect chemistry and defect-related properties of oxides, including electronic structure, charge transport, diffusion, and segregation. … [This] book is probably the only survey on semiconducting and photocatalytic properties of TiO₂ at present, particularly with respect to inclusion of the importance of defect chemistry. The research of the author in this area has attracted the prestigious award of the International Association for Hydrogen Energy. This book should be welcomed by the large research community interested in oxide semiconductors in general and TiO₂ in particular, as well as the growing community interested in photocatalysis.
—Professor Eric D. Wachsman, University of Maryland

This book of Prof. Nowotny is addressing the increasingly urgent need for a treatise on oxide semiconductors in general and TiO₂-based semiconductors in particular. … This book, which is the first extensive survey on the science of TiO₂, will be of great help to the research community involved in the studies of the properties of TiO₂.
