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.

Electrochemistry in Colloids and Dispersions. Edited by R. A .

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.

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!
