Available in PDF, EPUB and Kindle. Book excerpt: * At the present stage of development of surface science, there has seemed to be a need for a book-length review spanning the disciplines of surface physics and surface chemistry-a review to summarize and show the con nection between the observations from each discipline. The various results and theories, derived on the one hand from studies of the physical, electronic, and optical properties of surfaces and on the other hand from studies of the chemical activity of surfaces, supplement each other in the search for a realistic model of the surface. The improved understanding possible with such an interdisciplinary approach has been confirmed by recent develop ments which cannot be classified as either surface chemistry or surface physics. Specifically, recent new experimental techniques and quantum mechanical models have provided a much more accurate picture of the nature of the electronic energy levels (bonding orbitals) present at a solid surface. With this more accurate picture we are now able to reconcile the various chemical and physical models that appeared in the early literature on surfaces. The objective of this work has therefore been to describe the results and current models of surface science spanning a broad gray area between surface physics and surface chemistry with some overlap into each of these disciplines. Relevant aspects of surface chemistry are discussed; we cover chemical interactions where bonding and electronic properties dominate, but stop short of specialized topics such as surfactants or liquid/liquid interfaces.

Book Synopsis Catalysis Progress in Research by : Fred Basolo
Download or read book Catalysis Progress in Research written by Fred Basolo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This conference on Catalysis was held under the auspices ofthe NATO Science Committee as part of its continuing effort to promote the useful progress of science through international cooperation. The Science Committee Conferences are deliberately designed and struc tured to focus expert attention on what is not known, rather than what is known. The participants are carefully selected to bring together a variety of complementary viewpoints. Through intensive group discussion, they seek to reach agreement on conclusions and recommendations for future research which will be of value to the scientific community. We believe that the endeavour has been particularly successful in the pre sent case. Some twenty-five papers, either in the form of reprints or specially written reviews were contributed by the participants for advance circulation, to outline the state-of-the art in the three areas ofheterogeneous, homogeneous and metalloenzyme catalysis and to focus attention on key problems. The availability of this background material precluded the need for lengthy intro ductory presentations and permitted rapid initiation of interdisciplinary discussions. All participants gave generously and enthusiastically of their expertise and effort during the week of the meeting, of ten long past normal bedtime hours, and we extend to them our deep gratitude.

Book Synopsis Semiconductor Catalysis by : Robert P. Merrill
Download or read book Semiconductor Catalysis written by Robert P. Merrill and published by . This book was released on 1964 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretically and experimentally the relationship between the surface electrical properties of a semiconductor catalyst and its catalytic activity was explored. A program was proposed for the measurement of surface conductivity and recombination velocity on germanium simultaneously with the measurement of reaction kinetics of the decomposition of ethanol. The equipment to carry out these measurements included a system to operate a unique radio-frequency mass spectrometer, which was used to analyze the decomposition products. Key experiments to demonstrate the facility of the design, including measurements of ethanol decomposition on vacuum cleaved germanium and surface electrical properties of etched germanium wafers were made. In the kinetic experiments it was found that the catalysts produced by vacuum cleavage are much more active than catalysts produced by crushing in air and subsequent reduction in hydrogen, though the activation energies are similar. Treating the vacuum crushed catalyst with hydrogen lowers both the activation energy and the rate. Evidence is presented for the possible formation of a germanium hydride on the clean surfaces and the formation of an oxy-hydrogen complex on aircrushed catalysts.

This book was released on 2012-12-06 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Hands are useless if there are no eyes to see what is obvious." -M. V. Lomonosov Dear Reader, I invite you to open this book and step on the semiconductor surface, where the processes that form the subject of the book come into play. The surface of the semiconductor is attracting more and more interest among researchers, in fact researchers in two different fields. These are notably the physicists and engineers engaged in research in semi conductor physics and the making of semiconductor devices. The entire industry of semiconductor instruments hinges on the problem of the surface. The quality of semiconductor devices, whose use is growing steadily, depends essentially on the properties of the surface. The instability of these properties and their uncon trollable alterations with temperature and under the influence of environmental conditions result in a lack of stability in the performance of semiconductor devices, hence the high percentage of waste in their industrial production. The methods used in factory laboratories to prevent such waste are largely empirical. The properties of the surface, the nature of the physicochemical processes that take place on it, and the role of environmental factors still remain obscure. A major task of the semiconductor industry is to learn to control the properties of the surface.
