Modern Aspects of Electrochemistry, Volume 38 (Modern Aspects of Electrochemistry)

Topics in Number 38 include: -Solid State Electrochemistry encompassing modern equilibria concepts, thermodymanics and kinetics of charge carriers in solids. -Electron transfer processes, with special sections devoted to hydration of the proton and its heterogeneous transfer. -Electrosorption at electrodes and its relevance to electrocatalysis and electrodeposition of metals. -The behavior of Pt and other alloy electrocatalyst crystallites used as the electrode materials for phosphoric acid electrolyte fuel-cells. -Applications of reflexology and electron microscopy to the materials science aspect of metal electrodes. -Electroplating of metal matrix composites by codeposition of suspended particles, a process that has improved physical and electrochemical properties. 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 This volume comprises six chapters on aspects of fundamental and applied electrochemical science that will be of interest both to researchers in the basic areas of the subject and to those involved in aspects of electrochemical technologies. Chapter 1 is the first part of a 2-part, major contribution by Joachim Maier on Solid State Electrochemistry: Thermodynamics and Kinetics of Charge Carriers in Solids. Part 2 will follow in volume 39 to be published in year 2005. This contribution reviews modern concepts of the equilibria involving charge carriers in solids in terms of concentrations of defects in solids and at grain-boundaries, including doping effects. Complementarily, kinetics of charge transfer and ion transfer are treated in some detail in relation to conductance, kinetics of surface processes and electrode-kinetics involving solid-state processes. This chapter will be of major interest to electrochemists and physicists in the semiconductor field and that involving ionic solids. In the second chapter, Appleby presents a detailed discussion and review in modern terms of a central aspect of electrochemistry: Electron Transfer Reactions With and Without Ion Transfer. Electron transfer is the most fundamental aspect of most processes at electrode interfaces and is also involved intimately with the homogeneous chemistry of redox reactions in solutions.
