RefComment: XXX, 366 pages. Hardcover
Abstract: In volume III/21 an attempt is made to compile the reported data on superconducting materi-als, from the discovery of this phenomenon to the present day. The data comprise various modifications of a material, e.g. bulk state, thin films,implanted films, filamentary wires and others. Where available,data obtained under high pressure or after high energy particle irradia-tion are also tabulated. The goal of this volume is to establish a complete and reliable compilation of critically reviewed experimental data, excluding pure theoretical work. A particular effort was made to present not only superconducting data for a given substance, but also the complete characterization of the analysed sample. The large number of publications, more than 40,000 since 1913, requires a subdivision of the data in several subvolumes.

Abstract: Photoelectron spectroscopy has matured considerably during the last decade. The experimental techniques were improved markedly. Photon line sources and,in particular, synchrotron radiation sources are now routinely available in many places. The volume summarizes data on the bulk electronic structure of solids. Besides the photoelectron results, a limited set of other data (such as lattice constants and work functions) useful in the context of band structure information is presented.

Abstract: This ninth volume in Group IV of the renowned Landolt-Börnstein series considers and describes the electrochemical processes at the boundaries of electrodes and electrolytes. The book first presents a thorough overview of the field of electrochemistry, to impart a precise understanding of the involved systems, and secondly collects all relevant data of electrochemical systems as reported up to the present time. Phenomena and data are reported and considered from the constitutive viewpoints of electrochemistry, which also form the five chapters of Subvolume A: electrode potentials - cell voltages - electrode potentials of zero charge - free enthalpy of adsorption - exchange current densities. Each chapter opens with an introduction to its particular subject, and then presents the data in concise tables, arranged, as far as possible, according to the examined values.
