The significance of organometallic chemistry has constantly increased during the second half of this century. The Gmelin Institute recognizes this fact in publishing an entire series on organometallic compounds. This series has now started with the description of the organogermanium compounds. The present second volume in the organogermanium series continues the description of Ge(CH3)3R compounds, beginning with R=alkenyl and concluding with R=heterocycle. The remaining part of the volume covers completely the type Ge(C2H5)3R, which is the most voluminous of the GeR3R compounds. The volume concludes with an empirical formula index.
This book lays out a vision for a coherent framework for understanding complex systems. By developing the genuine idea of Brownian agents, the author combines concepts from informatics, such as multiagent systems, with approaches of statistical many-particle physics. It demonstrates that Brownian agent models can be successfully applied in many different contexts, ranging from physicochemical pattern formation to swarming in biological systems.

The present volume opens the Gmelin series on organogermanium compounds, that is, those compounds containing at least one germanium-to-carbon bond. This whole series is being coordinated by Professor J. Satge of the Universite Paul Sabatier in Toulouse. Germanium is of historical interest because its existence was predicted by Newlands in 1864 and by Mendeleeff in 1871 although it was not isolated until1887 by Winkler. Mendeleeff's predictions of the properties of germanium and its compounds by comparison with what was known of the chemistry of its neighbors, silicon and tin, proved remarkably accurate and included predictions of the existence of organic derivatives GeR and of their properties. 4 Although significant applications are as yet lacking for organogermanium compounds in contrast to organo-silicon, -tin, and -lead compounds there has been considerable interest in the parallel development of its chemistry. Up to 1983 about 1500 publications have appeared on organogermanium chemistry. The material of the present series will be grouped in a similar way as for the organotin series beginning with compounds containing only one germanium atom (mononuclear com pounds) and continuing with binuclear up to polynuclear compounds. Within each group the compounds are arranged by the kind of non-carbon substituents rather than by following the usual Gmelin principle of the last position using the Gmelin system of elements.
Plasma Atomic Physics

2021 · Springer Nature
Plasma Atomic Physics provides an overview of the elementary processes within atoms and ions in plasmas, and introduces readers to the language of atomic spectra and light emission, allowing them to explore the various and fascinating radiative properties of matter. The book familiarizes readers with the complex quantum-mechanical descriptions of electromagnetic and collisional processes, while also developing a number of effective qualitative models that will allow them to obtain adequately comprehensive descriptions of collisional-radiative processes in dense plasmas, dielectronic satellite emissions and autoionizing states, hollow ion X-ray emissions, polarized atoms and ions, hot electrons, charge exchange, atomic population kinetics, and radiation transport. Numerous applications to plasma spectroscopy and experimental data are presented, which concern magnetic confinement fusion, inertial fusion, laser-produced plasmas, and X-ray free-electron lasers’ interaction with matter. Particular highlights include the development of quantum kinetics to a level surpassing the almost exclusively used quasi-classical approach in atomic population kinetics, the introduction of the recently developed Quantum-F-Matrix-Theory (QFMT) to study the impact of plasma microfields on atomic populations, and the Enrico Fermi equivalent photon method to develop the “Plasma Atom”, where the response properties and oscillator strength distribution are represented with the help of a local plasma frequency of the atomic electron density. Based on courses held by the authors, this material will assist students and scientists studying the complex processes within atoms and ions in different kinds of plasmas by developing relatively simple but highly effective models. Considerable attention is paid to a number of qualitative models that deliver physical transparency, while extensive tables and formulas promote the practical and useful application of complex theories and provide effective tools for non-specialist readers.

W Tungsten
by Gerhard Czack, Gerhard Kirschstein, Wolfgang Kurtz, Frank Stein
2013 · Springer Science & Business Media
The volume describes physical properties of tungsten metal and covers specifically surface properties, electron emission, and field evaporation. Tungsten surfaces are probably the most extensively studied metal surfaces. Recently, experimentalists and theorists have focussed their interest on the atomic structure, lattice dynamics, and electronic properties of the W(100) surface. While the structure of the reconstructed low-temperature surface is well established, there are still unresolved problems concerning the structure at and above room temperature, the nature of the phase transition, and the driving force for the reconstruction. There are numerous and partly conflicting data on the surface energy, the self-diffusion parameters, and the work function of single-crystal and polycrystal tungsten surfaces. Electron emission, which is of fundamental importance for many applications, comprises thermionic, field, photofield, and photoelectric emission as well as emission induced by impinging electrons, atoms, or ions. Pioneering work in areas like thermionic or field emission is comprehensively discussed. Very recent studies of valence-band and core-level spectra moreover provide detailed information on intrinsic surface properties.
