Book Description
The purpose of this book is to discuss the phenomena associated with the segregation of one element in a multicomponent material. It describes the kinetics of segregation and contains a tabular summary of the pros and cons of the various models. The easy-to-read chapters outline in detail the macroscopic approach and provide an in-depth review of broken-bond models. This comprehensive informative resource also addresses important multicomponent systems. These systems include metals with non-metallic constituents, semiconductor-metal interfaces, steels and steel-related alloys, and real catalysts. Readers of this text will gain a good fundamental understanding and overview of surface, interfacial, and selvedge segregation. Those who have an interest in physics, vacuum science, material science, and chemical, mechanical, and electrical engineering will benefit from this imperative work.

Book Description
The book presents the fundamental aspects of surface segregation theory. The material is presented in a self-contained manner and mathematical procedures are worked through in some cases in order to provide the reader with the necessary opportunity to realize the restrictions under which the expressions are valid.

Book Description
DescriptionSurface Alloys and Alloy Surfaces is concerned with the structural, compositional, electronic and chemical properties of the surfaces of solids in which the surface layers, at least are alloyed. Two different categories of system are covered - the surfaces of bulk alloys (alloy surfaces) and surface phases in which one or more outermost atomic layers are alloyed, while the underlying bulk involves no such intermixing (surface alloys).Importance of TopicThe surfaces of bulk alloys have long been known to be of practical interest for their chemical properties. It has also long been known that the surface composition of such alloys commonly differs from that of the underlying bulk. However, our understanding of these chemical and physical phenomena is far from complete and the application of surface science methods to investigate these phenomena is a manifestation of a general trend to study the surfaces of increasing complexity. Surface alloy formation, as a much more recently recognized phenomenon deserves more attention.Why This TitleThis title is important as it provides new insights into a mixture of new and old problems. It is the first to cover the important mixture of material on surface alloys and alloy surfaces. Each chapter is written by experts in different areas of these two interrelated topics, covering theory and experiment, physics and chemistry, geometrical and electronic structure. The coverage of the surface alloy topic is especially novel as it is relatively newly-recognised as quite a common phenomenon.

Book Description
Bimetallic nanoparticles, also called nanoalloys, are at the heart of nanoscience because of their ability to tune together composition and size for specific purposes. By approaching both their physical and chemical properties, Nanoalloys: Synthesis, Structure & Properties provides a comprehensive reference to this research field in nanoscience by addressing the subject from both experimental and theoretical points of view, providing chapters across three main topics: Growth and structural properties Thermodynamics and electronic structure of nanoalloys Magnetic, optic and catalytic properties The growth and elaboration processes which are the necessary and crucial part of any experimental approach are detailed in the first chapter. Three chapters are focused on the widely used characterization techniques sensitive to both the structural arrangements and chemistry of nanoalloys. The electronic structure of nanoalloys is described as a guide of useful concepts and theoretical tools. Chapters covering thermodynamics begin with bulk alloys, going to nanoalloys via surfaces in order to describe chemical order/disorder, segregation and phase transitions in reduced dimension. Finally, the optical, magnetic and catalytic properties are discussed by focusing on nanoparticles formed with one element to track the modifications which occur when forming nanoalloys. The range and detail of Nanoalloys: Synthesis, Structure & Properties makes it an ideal resource for postgraduates and researchers working in the field of nanoscience looking to expand and support their knowledge of nanoalloys.

Book Description
High-temperature corrosion is a major problem affecting sectors such as the power generation, aerospace and metal-working industries. This important book summarises a wide range of research on ways of dealing with this important problem. The first part of the book reviews ways of modifying alloys to improve high-temperature corrosion resistance. The second part discusses surface treatments such as pre-treatments and coatings. The third part of the book summarises research on testing for high-temperature corrosion resistance and the development of common testing standards. It also reviews research on the behaviour of alloys in a wide range of service conditions such as furnace and boiler environments. The final part of the book discusses ways of modelling high-temperature corrosion processes to improve material performance and service life.With its distinguished editors and team of contributors drawn from some of the leading centres of research in the field, Novel approaches to improving high-temperature corrosion resistance is a standard reference for all those studying and dealing with high-temperature corrosion. - Summarises a wide range of research on ways of dealing with high-temperature corrosion - Discusses ways of modelling high-temperature corrosion processes to improve material performance and service life - A standard reference for all those studying and dealing with high-temperature corrosion

Book Description
The 17th University Conference on Ceramics, which also was the 7th LBL/MMRD International Materials Symposium, was held on the campus of the University of California at Berkeley from July 28 to August 1, 1980. It was devoted to the subject of surfaces and interfaces in ceramic and ceramic-metal systems. The program was timely and of great interest, as indicated by the large number of contributed papers, which included contributions from ten foreign countries. These proceedings are divided into the following categories dealing with the chemistry and physics of interfaces: calculations of interface/surface states, characterization of surfaces and inter faces, thermodynamics of interfaces, influence of surface and inter faces on selected ceramic processes, grain boundary structures, effects of grain boundaries on deformation and fracture, interfacial phenomena, formation of interfaces, development of adhesion, and reactions at interfaces. A number of papers deal specifically with the Si-Si02 interface, which probably has received more attention than any other because of its importance in the electronics industry. This coverage fulfills the principal objective of the symposium which was to explore and assess the current fundamental understand ing of interfaces and surfaces. A parallel objective of the symposium was fulfilled by a group of papers dealing with the correlation of interfacial characteris tics with mechanical behavior. This group includes papers dealing with the adherence of dissimilar materials at interfaces.

Book Description
For catalytic practitioners who are concerned with laboratory studies of reaction mechanisins, as often as not catalyst deactivation is· treated as a nuisance to be ignored or factored out of the experimental results. How ever, the engineer concerned with the design and opera tion of real catalysts and processes cannot afford this luxury: for him deactivation and the need for regenera tion are inevitable facts of life which need to be treated as quantified design parameters. The first chapter in this volume by Prof. J. B. Butt deals with catalyst deactivation and regeneration as processes in their own right, and shows how they are to be approached from kinetic and design points of view. Catalytic olefin polymerization spans a very wide field in catalytic process chemistry and technology. Processes of this sort range from the generation of high volume products such as polyethylene and polypropylene, through more specialized commercial products, to con versions that still remain laboratory curiosities. The reaction chemistry is, in detail, often very complex. However, because of the insight provided by organo metallic reaction chemistry, many of the polymerization mechanisms are reasonably well understood, and the way in which product stereospecificity may be obtained is also understood in considerable detail. This highly complex subject is reviewed in detail in the second chapter of this volume by Prof. I. Pasquon and Dr. G. Giannini.
