in these areas. There is a table giving a quick survey of the types of substances that have been separated, with references to the original publications. The final chapter includes a late list of publications that appeared while the book was in preparation. extending the coverage to about the end of March 1992. To summarize, the book offers a detailed and apparently complete survey of the literature on capillary electrophoresis. The information content is greater than that in the usual Arini/cr/ Revicws of Analvfical Ciiernistry. On the other hand, the published work is reviewed in an uncritical way. Consequently. one finds quite contradictory results cited in short succession. and some material is repeated in the individual chapters, thus increasing the length unnecessarily. However. these criticisms should not detract from the author’s achievement in having produced a book of this kind that is so up-to-date (reflecting the state of knowledge at the beginning of 1992). I t should be regarded as a handbook and reference source on CE rather than a textbook. It will be extremely useful to everyone who wishes to have rapid access to the literature on the subject. Heiiir Engeliiardt Angewandte Physikalische Chemie Universitiit des Saarlandes Saarbriicken (FRG) Electrochemistry in Colloids and Dispersions. Edited by R. A . Mort kay and J. Texter. VCH Publishers, New York/VCH Verlagsgesellschaft, Weinheim, 1992. XV, 546 pp., hardcover D M 21 0.00.-ISBN 1-56081 -573-6/3-527-89 573-6 This book contains 36 contributions by 83 authors. Some of the contributions are written in the style of review articles, while others report original research. They are based o n papers presented at the Symposium on Electrochemistry in Microheterogeneous Fluids. which was held in August 1991 in New York under the auspices of the Division of Colloid and Surface Chemistry of the American Chemical Society. The aim of the symposium was to review the current state of knowledge in this rapidly developing interdisciplinary field. which lies between electrochemistry and the physical chemistry of colloidal systems. Studies on biophysical systems were deliberately excluded. The book consists of five sections as follows: 1. Electroanalytical Methods and Applications (6 articles); 2. Transport Phenomena in Micellar Systems, Suspensions of Liposomes, and Microemulusions (9 articles); 3. Polymers and Latices (5 articles); 4. Electrosyntheses and Electrocatalytic Reactions (4 articles); 5. Colloidal Metals and Semiconductors (1 2 articles). Readers with interests in electrochemistry and in the physical chemistry of colloidal systems will probably not find much here that is new. except for the articles in the section on colloidal metals and semiconductors which together present a good picture of current development trends in this area. For those wishing to learn about the electrochemistry of colloidal systems the introductory chapter by one of the editors (J. Texter) will be of particular interest. In about 20 pages (with 252 literature references) Texter gives a comprehensive overview of the background to the individual contributions that follow. with examples taken from important results obtained by leading workers in this field. Although the editors acknowledge the “cheerful and professional assistance” of a number of people at the research laboratories of the Eastman Kodak Company in enabling them to submit the articles to the publishers in camera-ready form, the book is by no means cheap. What, then, makes it particularly useful? Owing to the rising costs of scientific journals and the fact that departmental libraries have had their budgets frozen for several years, they have been forced to cut out more and more titles. The disturbingly impoverished state of such libraries is readily apparent to everyone using them. As a result scientists in Germany find that access to original publications is increasingly laborious and timeconsuming. Copies of articles that seem to be especially important can be obtained from central libraries. but the cost is then charged to the research group’s basic operating budget. which is usually small. In view of this situation it could be worthwhile to buy this volume, provided that the interested reader can persuade the library committee to d o so despite the high price. Dierricii Worrnimn Institut fur Physikalische Chemie der Universitlt Koln ( F R G ) Proton Conductors. Solids, Membranes and Gels-Materials and Devices. (Series: Chemistry of Solid State Materials. Vol. 2, series editors: A . R. West and H . Ba.uter.) Edited by P. Colornban. Cambridge University Press. Cambridge, 1992. XXXII, 581 pp., hardcover L 75.00. ISBN 0-5223831 7-X The second volume of the series “Chemistry of Solid State Materials” is concerned with an aspect of the chemistry of hydrogen that is relatively unpamiliar to the chemist. namely protons in “solids with pathological symptoms”. To qualify as a solid electrol-yte a material must have disorder. which can be induced thermally or chemically. In solids the ions become mobile enough for conduction to occur only at high temperatures. Chemical modifications can be achieved in a multistage synthesis so as to introduce specific structural defects which confer the high temperature conductivity needed for applications in high performance batteries or fuel cells. In Chapter 3 of this book the special characteristics of solid ionic conductors, with the emphasis on proton conductors. are skillfully and concisely presented by the editor, P. Colomban, and A. Novak. From this it already becomes clear that, because of the complicated naturc of most proton conductors, they d o not yet offer the basis for a reliable technology or a large commercial market. Nevertheless, the authors report many novel and exciting results of fundamental research on hydrogen-containing materials, which are seldom adequately covered in conventional textbooks and data complications. One moves on eagerly to the chapters that treat particular groups of materials with special types of defect structures, the effects that these have on proton conduction, and especially the technology of applying them. The chapter on “Hydrogen Bond and Protonic Species” (100 pp.) describes the fundamentals of chemical bonding and proton structure in the compounds formed by hydrogen with the strongly electronegative elements oxygen, fluorine, and nitrogen. The special position of proton conductors compared with other types of solid ionic conductors is emphasized here. This chapter also includes a contribution on hydrogen in metals, by I . Svare. The discussions of adsorption and desorption, diffusion, tunneling, and the structure of metal hydrides go beyond the area defined by the book’s title: here one is not mainly concerned with the proton H + but with the valence states H - and Ho. Nevertheless, the article serves a useful purpose in completing the picture of the behavior of hydrogen in its compounds. and especially the dynamics of the bonding, and at the same time defining a boundary to the subject!
