Important advances in a subject are as often promoted by a new technique as by new concepts and theories. In the study of electrode reactions which involve diffusion in a primary or a secondary step, the development and use of techniques involving rotating disc electrodes and derived instrumentation based on ring-disc and split-ring systems has enabled advances of great importance to be made in the quantitative examination of diffusion processes at electrodes and their role in electrode processes generally. The technique allows precisely defined mass-transport conditions to be set up which can be subjected to exact mathe matical analysis so that quantitative treatment of hydrodynamic and diffusion behavior can be made. Of special interest for elec trochemists is the opportunity which the rotating ring-disc system offers for studying solution-soluble intermediates in sequential electrode processes and the kinetics of their reactions in solution. In this book by Pleskov and Filinovskii, both the experimental techniques and the mathematical analysis for the treatments of results for various conditions and types of reaction are described in detail. We believe that presentation of work that has been car ried out by means of rotating electrode techniques, to a large extent by Russian workers, in the form of a concise book will be of great value both to electrochemists and kineticists, and those interested in the physics of fluid motion.

Electrochemistry plays a key role in a broad range of research and applied areas including the exploration of new inorganic and organic compounds, biochemical and biological systems, corrosion, energy applications involving fuel cells and solar cells, and nanoscale investigations. The Handbook of Electrochemistry serves as a source of electrochemical information, providing details of experimental considerations, representative calculations, and illustrations of the possibilities available in electrochemical experimentation. The book is divided into five parts: Fundamentals, Laboratory Practical, Techniques, Applications, and Data. The first section covers the fundamentals of electrochemistry which are essential for everyone working in the field, presenting an overview of electrochemical conventions, terminology, fundamental equations, and electrochemical cells, experiments, literature, textbooks, and specialized books. Part 2 focuses on the different laboratory aspects of electrochemistry which is followed by a review of the various electrochemical techniques ranging from classical experiments to scanning electrochemical microscopy, electrogenerated chemiluminesence and spectroelectrochemistry. Applications of electrochemistry include electrode kinetic determinations, unique aspects of metal deposition, and electrochemistry in small places and at novel interfaces and these are detailed in Part 4. The remaining three chapters provide useful electrochemical data and information involving electrode potentials, diffusion coefficients, and methods used in measuring liquid junction potentials. * serves as a source of electrochemical information * includes useful electrochemical data and information involving electrode potentials, diffusion coefficients, and methods used in measuring liquid junction potentials * reviews electrochemical techniques (incl. scanning electrochemical microscopy, electrogenerated chemiluminesence and spectroelectrochemistry)

The book is devoted to investigation of a series of problems of convective heat and mass transfer in rotating-disk systems. Such systems are widespread in scienti?c and engineering applications. As examples from the practical area, one can mention gas turbine and computer engineering, disk brakes of automobiles, rotating-disk air cleaners, systems of microclimate, extractors, dispensers of liquids, evaporators, c- cular saws, medical equipment, food process engineering, etc. Among the scienti?c applications, it is necessary to point out rotating-disk electrodes used for experim- tal determination of the diffusion coef?cient in electrolytes. The system consisting of a ?xed disk and a rotating cone that touches the disk by its vertex is widely used for measurement of the viscosity coef?cient of liquids. For time being, large volume of experimental and computational data on par- eters of ?uid ?ow, heat and mass transfer in different types of rotating-disk systems have been accumulated, and different theoretical approaches to their simulation have been developed. This obviously causes a need of systematization and generalization of these data in a book form.

It is hard to overstate the importance of electrochemistry in the modern world: the ramifications of the subject extend into areas as diverse as batteries, fuel cells, effluent remediation and re-cycling, clean technology, elect- synthesis of organic and inorganic compounds, conversion and storage of solar energy, semiconductor processing, material corrosion, biological electron transfer processes and a wide range of highly specific analytical techniques. The impact of electrochemistry on the lives of all of us has increased immeas- ably, even in recent years, but this increase has not been reflected in the level or content of courses taught at universities, many of which portray the subject as a collection of arcane recipes and poorly understood formulae of marginal importance to the mainstream of chemistry. This approach reached its nadir with the recent extraordinary furore surrounding the purported discovery of cold fusion, where two electrochemists claimed to have shown that the fusion of deuterium nuclei could be effected under ambient conditions by the electrochemically induced intercalation of deuterium atoms into palladium. Whatever the truth behind such claims, their discussion revealed a lamentable lack of knowledge of modern elect- chemistry, not only among science writers for the popular press, but among many professional chemists and physicists whose acquaintance with the subject seems, for the most part, to have stopped somewhere about the time of Nernst. In a year in which Professor R.

For full market implementation of PEM fuel cells to become a reality, two main limiting technical issues must be overcome- cost and durability. This cutting-edge volume directly addresses the state-of-the-art advances in durability within every fuel cell stack component. [...] chapters on durability in the individual fuel cell components -- membranes, electrodes, diffusion media, and bipolar plates -- highlight specific degradation modes and mitigation strategies.
