… 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, 2012The 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 MarylandThis 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.—Professor Sebastian Fiechter, Helmholtz-Centre Berlin for Materials and Energy
