Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive account of the phenomena that occur when simple gases interact with surfaces, this text takes a fundamental perspective. Physical adsorption involves atomic or molecular films bound to surfaces by less than 0.5 eV per particle. Physically absorbed thin films exhibit remarkably diverse properties and behave in a manner characteristic of two-dimensional matter. This exploration focuses on monolayer physics, emphasizing atomic rather than molecular adsorption. The phase diagrams of physically absorbed films are diverse and rich in structure because of the subtle and varied competition between the two interactions: the mutual interaction between adsorbed molecules, and the force binding each molecule to the surface. The authors explain the microscopic origin of these forces in terms of constituent electrons and nuclei. They then examine the structural and dynamical properties of these films in the context of atomic and solid-state physics, statistical mechanics, and computer simulations. This text will be of interest to research chemists, physicists, and engineers alike, as well as students in these fields. Key literature citations allow readers to trace important developments, and thought-provoking problems are addressed in detail.

Download or read book Concepts in Surface Physics written by M-C. Desjonqueres and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook is intended as an introduction to surface science for graduate students. It began as a course of lectures that we gave at the University of Paris (Orsay). Its main objectives are twofold: to provide the reader with a compre hensive presentation of the basic principles and concepts of surface physics and to show the usefulness of these concepts in the real world by referring to experiments. It starts at a rather elementary level since it only requires a knowledge of solid state physics, quantum mechanics, thermodynamics and statistical physics which does not exceed the background usually taught to students early in their university courses. However, since it finally reaches an advanced level, we have tried to render it as self-contained as possible so that it remains accessible even to an unexperienced reader. Furthermore, the emphasis has been put on a pedagogical level rather than on a technical level. In this spirit, whenever possible, models which are simplified, but which contain the features that are essential to the appearance of the phenomena, have been set up and solved in a completely analytical way. The logic should be transparent enough for the reader although, most often, a more rigorous solution would need the use of a computer. To conclude, we have tried to give an account of surface physics which should be of use to the theoretician as well as to the experimentalist. The following comments can be made on the contents of this book.

Download or read book Fundamentals of Adsorption written by M. Douglas LeVan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1080 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Adsorption is the proceedings of the fifth International Conference on the Fundamentals of Adsorption, which was held on May 13-18, 1995 at the Asilomar Conference Center, Pacific Grove, California. This conference was organized completely under the auspices of the International Adsorption Society. It was attended by 196 participants from 24 countries. Members of the Scientific Advisory Board, together with the Conference Committee, selected papers for presentation from a large number of proposals involving an especially high level of international participation. The fundamental aspects of adsorption is a subject which has grown rapidly in recent years, drawing researchers from many disciplines including materials science, chemistry, physics, biochemistry and biotechnology, and chemical, civil, mechanical and environmental engineering. Fundamentals of Adsorption serves as an excellent reference and may be used as a primary text for a graduate level course on adsorption research or as a secondary text for a course on any of the disciplines mentioned above.
Download or read book Dynamics of Adsorption at Liquid Interfaces written by S.S. Dukhin and published by Elsevier. This book was released on 1995-04-11 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the first of its kind, this book provides a valuable introduction for scientists and engineers interested in liquid/fluid interfaces and disperse systems to the rapidly developing area of adsorption dynamics. It is the first extensive review available on the subject of dynamics of adsorption and gives a general summary of the current state of adsorption kinetics theory and experiments. Current progress in recently designed set-ups and improved and generalised known methods for studying interfacial relaxations is reviewed. In addition, the role of the electric charge of surfactants in the adsorption process is discussed in terms of a non-equilibrium distribution of adsorbing ions in the diffuse layer. Present theories of the effect of dynamic adsorption layers on mobile surfaces, such as moving drops and bubbles, based on both diffusion and kinetic controlled adsorption models are described and efficient approximate analytical methods to solve the mathematical problem of coupling surfactant transport and hydrodynamics are introduced. The role of a dynamic adsorption layer in bubble rising, film drainage and film stabilisation and in complex processes such as flotation and microflotation is discussed. Containing more than 1100 references, the book is essential reading for industrial scientists and graduate and post-graduate students in physical, surface and colloid chemistry, physico-chemical hydrodynamics, water purification and mineral processing.
Download or read book Gas Adsorption Equilibria written by Jürgen U. Keller and published by Springer Science & Business Media. This book was released on 2006-06-23 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is intended to present for the first time experimental methods to measure equilibria states of pure and mixed gases being adsorbed on the surface of solid materials. It has been written for engineers and scientists from industry and academia who are interested in adsorption based gas separation processes and/or in using gas adsorption for characterization of the porosity of solid materials. This book is the result of a fruitful collaboration of a theoretician (JUK) and an experimentalist (RS) over more than twelve years in the field of gas adsorption systems at the Institute of Fluid- and Thermodynamics (IFT) at the University of Siegen, Siegen, Germany. This collaboration resulted in the development of several new methods to measure not only pure gas adsorption, but gas mixture or coadsorption equilibria on inert porous solids. Also several new theoretical results could be achieved leading to new types of so-called adsorption isotherms based on the concepts of molecular association and – phenomenologically speaking – on that of thermodynamic phases of fractal dimension. Naturally, results of international collaboration of the authors over the years (1980-2000) also are included.

Book excerpt: The Collected Works of Irving Langmuir, Volume 1: Low-Pressure Phenomena is a 16-chapter text that covers the early work of Irving Langmuir, beginning with his doctoral thesis written in 1906, focusing on the chemical and physical aspects of low-pressure phenomena. The first chapters deal with the dissociation of various gases produced by hot platinum wires and the convection and conduction of gases at high temperatures. The subsequent chapters consider the velocity of reactions in gases, the chemically active modification of hydrogen, and the dissociation of hydrogen into atoms. Considerable chapters are devoted to chemical reactions at very low pressures. The final chapters discuss the radiation as an important factor in chemical action and the mechanism of the catalytic action of platinum in the reactions between hydrogen and oxygen. This book is of value to physical chemists and physical chemistry researchers.
