Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The present volume completes the description of the interactions and chemical reactions of elemental tungsten with metallic elements, treating its reactions with antimony, bismuth, and the alkali and alkaline earth metals. The reactions of tungsten with these elements are in most cases confined to surface regions. Corrosion of tungsten and mutual solubility are usually very low. An exception is the W - Be system, in which several intermetallic phases are formed. The surface processes in some of the other systems covered in the present volume evoked considerable scientific and practical interest, documented by the large number of publications. This holds particularly for the Cs-on-W and Ba-on-W surface systems. Cs- and Ba-activated tungsten electrodes were and are used in many technical and laboratory appliances. One example is the Cs diode device for thermionic energy conversion. Surface ionization of Cs and W is widely applied in ion sources and for some time attracted great attention with respect to its potential use in ion rocket propulsion engines. Cs-on-W is also a logical system for basic research on chemisorption due to the propitious chemical, crystallographic, and atomic properties of adsorbent and adsorbate. The majority of existing models for the chemisorption bond has been experimentally checked on this system. The particular interest in the W - Cs and W - Ba systems is reflected in the large portion of the text (256 pages) devoted to these systems.

This book was released on 2024-09-25 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to be the preeminent university chemistry textbook for environmental engineers. It provides undergraduate and graduate environmental engineering students with basic concepts and practical knowledge about chemistry that they would need in their professional careers. It focuses on the fundamental concepts of chemistry and its practical applications (e.g., understanding fate and transport of chemicals/pollutants in the environmental as well as the chemical/physicochemical processes applied in environmental engineering industry). This book also serves as a valuable resource for entry-level professionals to solidify their fundamental knowledge in environmental engineering chemistry. This book Presents the fundamentals of chemistry with focus on the needs of environmental engineers. Explains how an understanding of chemistry allows readers a better understanding of the fate and transport of chemicals in the environment as well as various treatment processes. Examines the fundamentals of chemical reaction equilibrium from learning the basics of thermodynamics. Presents the basic types and designs of reactors as well as reaction kinetics.
