Modern Aspects Of Electrochemistry 42

This volume analyzes and summarizes recent developments in several key interfacial electrochemical systems in the areas of fuel cell electrocatatalysis, electrosynthesis and electrodeposition. The six Chapters are written by internationally recognized experts in these areas and address both fundamental and practical aspects of several existing or emerging key electrochemical technologies. The Chapter by R. Adzic, N. Marinkovic and M. Vukmirovic provides a lucid and authoritative treatment of the electrochemistry and electrocatalysis of Ruthenium, a key element for the devel- ment of efficient electrodes for polymer electrolyte (PEM) fuel cells. Starting from fundamental surface science studies and interfacial considerations, this up-to-date review by some of the pioneers in this field, provides a deep insight in the complex catalytic-electrocatalytic phenomena occurring at the interfaces of PEM fuel cell electrodes and a comprehensive treatment of recent developments in this extremely important field. Several recent breakthroughs in the design of solid oxide fuel cell (SOFC) anodes and cathodes are described in the Chapter of H. Uchida and M. Watanabe. The authors, who have pioneered several of these developments, provide a lucid presentation d- cribing how careful fundamental investigations of interfacial electrocatalytic anode and cathode phenomena lead to novel electrode compositions and microstructures and to significant practical advances of SOFC anode and cathode stability and enhanced electrocatalysis.

MODERN ASPECTS OF ELECTROCHEMISTRY No. 42 Edited by Constantinos Vayenas University of Patras, Greece Topics in Number 42 include: The electrochemistry and electrocatalysis of Ruthenium in regards to the development of electrodes for Polymer Electrolyte Membrane (PEM) fuel cells Breakthroughs in Solid Oxide Fuel Cell (SOFC) anodes and cathodes leading to improved electrocatalysis Electrocatalysis of the electrochemical reduction of CO2 on numerous metals The interfacial phenomena of electrodeposition and codeposition, and the need for new theoretical analyses of the electrode-electrolyte interface Advantages of scanning tunneling microscopy (STM) in understanding the basics of catalysis, electrocatalysis and electrodeposition The role of electrochemistry in emerging technologies including electrodeposition and electroforming at the micro and nano levels, semiconductor and information storage, including magnetic storage devices, and modern medicine From reviews of previous volumes: "This long-standing series continues its tradition of offering high quality reviews of established and emerging subject areas, together with the less common aspects of electrochemical science ... Deserves a place in electrochemistry libraries and should prove useful to electrochemists and related workers."--Chemistry and Industry "Continues the valuable service that has been rendered by the Modern Aspects series." - Journal of Electroanalytical Chemistry "Will definitely be of much use to researchers in the field of electrochemistry ... The editors of this well-produced volume deserve all appreciation for maintaining the excellent standard of the series." - Bulletin of Electrochemistry "Extremely well-referenced and very readable ... Maintains the overall high standards of the series." - Journal of the American Chemical Society.

Recognized experts present incisive analysis of both fundamental and applied problems in this continuation of a highly-acclaimed series. Topics discussed include: The way in which electrochemical systems may function as on a single electrode; The foundational area of voltaic measurements at liquid interfaces; Direct methanol fuel cells, which would avoid the unpleasant necessity faced by the current general of fuel cells - namely, using hydrogen; Dynamic processes in molten salts; Electrochemical techniques and Microbial Induced Corrosion (MIC).

This volume of Modern Aspects of Electrochemistry contains six chapters. The first four chapters are about phenomena of interest at the microscopic level and the last two are on phenomena at the macroscopic level. In the first chapter, Uosaki and Kita review various theoretical models that have been presented to describe the phenomena that occur at an electrolyte/ semiconductor interface under illumination. In the second chapter, Orazem and Newman discuss the same phenomena from a different point of view. In Chapter 3, Bogus lavsky presents state-of-the-art considerations of transmembrane potentials and other aspects of active transport in biological systems. Next, Burke and Lyons present a survey of both the theoretical and the experimental work that has been done on hydrous oxide films on several metals. The last two chapters cover the topics of the production of chlorine and caustic and the phenomena of electrolytic gas evol ution. In Chapter 5, Hine et al. describe the engineering aspects of the three processes used in the chi or-alkali industry, and in Chapter 6, Sides reviews the macroscopic phenomena of nucleation, growth, and detachment of bubbles, and the effect of bubbles on the conduc tivity of and mass transfer in electrolytes.

No. 29 offers new insights into the energies of activation of electrode reactions and the interfacial behavior of proteins.

In the last decade, the evolution of electrochemistry away from concern with the physical chemistry of solutions to its more fruitful goal in the study of the widespread consequences of the transfer of electric charges across interphases has come to fruition. The turning of technology away from an onward rush, regardless, to progress which takes into account repercussions of techno logical activity on the environment, and the consequent need for a reduction and then termination of the injection of CO into 2 the atmosphere (greenhouse effect), together with a reckoning with air and water pollution in general, ensures a long-term need for advances in a basic knowledge of electrochemical systems, an increased technological use of which seems to arise from the environmental necessities. But a mighty change in attitude needs to spread among electro chemists (indeed, among all surface chemists) concerning the terms and level in which their field is discussed. The treatment of charge transfer reactions has often been made too vaguely, in terms, it seemed, of atom transfer, with the electron-transfer step, the essence of electrochemistry, an implied accompaniment to the transfer of ions across electrical double layers. The treatment has been in terms of classical mechanics, only tenable while inadequate questions were asked concerning the behavior of the electron in the interfacial transfer. No process demands a more exclusively quantal discussion than does electron transfer.
