Editorial Reviews

The new volume of the Modern Aspects of Electrochemistry series proceeds as in the past with five chapters covering both the electrolyte solution and the interfacial electrode process sides of the field. Applications of the electrode processes involving hydrogen are, especially the behavior of underpotential-deposited H, sorption of H into metals, and the kinetics and mechanisms of cathodic evolution of H2. Electroless metal deposition is reviewed. The development of computational electrochemistry and its applications to problems in electrochemical kinetics is examined. The properties of electrolyte solutions at high concentrations are studied. Finally, applications of the Born theory to solvent polarization by ions are critically reexamined. Annotation c.

A collection of international studies that describe progress in both fundamental and applied aspects of electrochemical science. The five chapters address ultrahigh-vacuum surface analytical methods in electrochemical studies of single-crystal surfaces; potential- modulated reflectance spectroscopy studies of the electronic transitions of chemisorbed carbon monoxide; low-temperature electrochemistry at high-Tc superconductor/ionic conductor interfaces; quantum theory of charge-transfer processes in condensed media; and a modern approach to surface roughness applied to electrochemical systems.
