Book Description
Chemisorption and Reactions on Metallic Films, Volume 2 is a four-chapter text that describes the role of evaporated metal films in advancing the understanding of the metal-gas interface chemistry and in understanding of adsorption and catalysis at metal surfaces. This volume first describes film structure and properties, particularly of random polycrystalline films, as well as the concepts of the adsorption and kinetic phenomena. The topic is followed by an overview of the main classes of catalytic reactions that have been studied over evaporated metal film catalysts. A chapter explores the preparation, characterization, structure, and surface properties of alloy films. The theory of the oxidation of metals and the advantages and disadvantages of using thin metal films in oxidation work are considered in the concluding chapter, along with a brief discussion on their use in kinetic and mechanistic studies. Research scientists and graduate students who are interested in the fundamentals of adsorption and catalysis will find this volume invaluable.

Book Description
Principles of Adsorption and Reaction on Solid Surfaces As with other books in the field, Principles of Adsorption and Reaction on Solid Surfaces describes what occurs when gases come in contact with various solid surfaces. But, unlike all the others, it also explains why. While the theory of surface reactions is still under active development, the approach Dr. Richard Masel takes in this book is to outline general principles derived from thermodynamics and reaction rate theory that can be applied to reactions on surfaces, and to indicate ways in which these principles may be applied. The book also provides a comprehensive treatment of the latest quantitative surface modeling techniques with numerous examples of their use in the fields of chemical engineering, physical chemistry, and materials science. A valuable working resource and an excellent graduate-level text, Principles of Adsorption and Reaction on Solid Surfaces provides readers with: * A detailed look at the latest advances in understanding and quantifying reactions on surfaces * In-depth reviews of all crucial background material * 40 solved examples illustrating how the methods apply to catalysis, physical vapor deposition, chemical vapor deposition, electrochemistry, and more * 340 problems and practice exercises * Sample computer programs * Universal plots of many key quantities * Detailed, class-tested derivations to help clarify key results The recent development of quantitative techniques for modeling surface reactions has led to a number of exciting breakthroughs in our understanding of what happens when gases come in contact with solid surfaces. While many books have appeared describing various experimental modeling techniques and the results obtained through their application, until now, there has been no single-volume reference devoted to the fundamental principles governing the processes observed. The first book to focus on governing principles rather than experimental techniques or specific results, Principles of Adsorption and Reaction on Solid Surfaces provides students and professionals with a quantitative treatment of the application of principles derived from the fields of thermodynamics and reaction rate theory to the investigation of gas adsorption and reaction on solid surfaces. Writing for a broad-based audience including, among others, chemical engineers, chemists, and materials scientists, Dr. Richard I. Masel deftly balances basic background in areas such as statistical mechanics and kinetics with more advanced applications in specialized areas. Principles of Adsorption and Reaction on Solid Surfaces was also designed to provide readers an opportunity to quickly familiarize themselves with all of the important quantitative surface modeling techniques now in use. To that end, the author has included all of the key equations involved as well as numerous real-world illustrations and solved examples that help to illustrate how the equations can be applied. He has also provided computer programs along with universal plots that make it easy for readers to apply results to their own problems with little computational effort. Principles of Adsorption and Reaction on Solid Surfaces is a valuable working resource for chemical engineers, physical chemists, and materials scientists, and an excellent text for graduate students in those disciplines.

Book Description
This book offers a unique perspective of the impact of scanning probe microscopies on our understanding of the chemistry of the surface at the nanoscale. Research oriented, with the concepts gleaned from Scanning Tunnelling Microscopy being related to the more established and accepted views in surface chemistry and catalysis the authors have addresses the question "How do the models based on classical spectroscopic and kinetic studies stand up to scrutiny at the atom - resolved level?". In taking this approach the reader, new to the field of surface chemistry, should be able to obtain a perspective on how the evidence from STM confirms or questions long standing tenets. An emphasis is given to "how did we get to where we are now" and a large number of figures from the literature are included along with suggestions for further reading. Topics discussed include: - the dynamics of oxygen chemisorption at metal surfaces - control of oxygen states and surface reconstruction - dissociative chemisorption of diatomic and hydrocarbon molecules - nanoparticles and chemical reactivity - STM at high pressures - structural studies of sulfur containing molecules and molecular templating This book will appeal to all those who wish to become familiar with the contribution Scanning Tunnelling Microscopy has made to the understanding of the field of surface chemistry and heterogeneous catalysis and also to those who are new to catalysis, a fascinating and important area of chemistry.

Book Description
This book presents experimental data and recent results of model calculations on the formation of natural oxide film on metal surfaces and of metal hydride formation. Such films are responsible for corrosion, friction, and wear of metallic materials. Describing mostly the authors own research, this monograph gives an overview of models suitable for metal-gas reactions and demonstrates how complex metal-gas interactions can be analyzed by standard procedures of chemical kinetics. The book, and the data and equations it contains, will be useful to researchers in surface science, condensed-matter physics, and materials science.

Book Description
High-strength steels are susceptible to delayed cracking under suitable conditions. Frequently such a brittle failure occurs at a stress that is only a fraction of the nominal yield strength. Considerable controversy exists over whether such failures result from two separate and distinct phenomena or whether there is but one mechanism called by two different names. Stress-corrosion cracking is the process in which a crack propagates, at least partially, by the stress induced corrosion of a susceptible metal at the advancing tip of the stress-corrosion crack. There is considerable evidence that this cracking results from the electrtrochemical corrosion of a metal subjected to tensile stresses, either residual or externally applied. Hydrogen-stress cracking is cracking which occurs as the result of hydrogen in the metal lattice in combination with tensile stresses. Hydrogen-stress cracking cannot occur if hydrogen is prevented from entering the steel, or if hydrogen that has entered during processing or service is removed before permanent damage has occurred. It is generally agreed that corrosion plays no part in the actual fracture mechanism. This report was prepared to point out wherein the two fracture mechanisms under consideration are similar and wherein they differ. From the evidence available today, the present authors have concluded that there are two distinct mechansims of delayed failure. (Author).
