SoUd State Gas Sensors By P. T. Moeeley and 8. C. Tofield (eds.), publiabed by Adam Hi&m, Bristol/ Philadelphia, 1987,245 pp., 135.00, ISBN 0-85274-514-1.
The book is composed of 10 papers and reviews, which are derived from a symposium held in Oxford in 1985 for a group of companies working in the solid-state gas sensor field. The contents follows a more or less chronological sequence, dealing with galvanic oxygen sensors (Ch. l), catalytic gas sensors (Chs. 2 and 3) and the characterization (Ch. 4), response mechanisms (Ch. 5) and selectivity-promoting modifications (Ch. 6) as well as new device concepts (Ch. 7) of semiconductors. Basic scientific concepts of gas sensor materials are treated in Chs. 8 and 9. Chapter 10 deals with the state of the art and future prospects for solid-state gas sensors. The editors have tried to h&&light areas that are important in new device development and evaluation. The emphasis lies on catalytic gas sensors and semiconductors, because, according to the Preface, these subjects are underemphasixed in many scientific or technical reviews. As a results, the book does not cover the broad area of solid-state gas sensors that is suggested by its title. Only the final chapter pays minor attention to important new developments. Therefore, the book does not satisfy the need for a comprehensive overview of somebody wanting to enter the very interesting solidstate gas sensor field. On the other hand, the scientific level and the good lay-out will catalyse the introduction to the specific subjects treated and will present a well documented review for insiders. Gas sensor research is preeminently a multidisciplinary approach. This prerequisite is well reflected in the book. M. S. NIEUWEEiHUIZEN
