Book Description
The report summarizes work done in the field of rarefied gas dynamics. The main emphasis was on an aspect which is beginning to receive much more attention than in the past, i.e. the mutual relationships between the fields of gas surface interactions and kinetic theory. The recent work done in this area is reviewed and possible developments are pointed out. (Author).

Book Description
Interface phenomena are most fascinating because of the mixing of different scales and the interference of diverse physical processes. This makes it necessary to use different levels of description: microscopic, kinetic, and gas-dynamical. A unified quasiclassical approach is used to answer practical questions dealing with inelastic gas-surface scattering, the kinetics of adsorption layers, the evolution of inhomogeneities and defects at the surface, the Knudsen layer, the development of boundary conditions on the kinetic and gas-dynamical levels, the determination of exchange and slip coefficients, and so on.

Book Description
This book gives a representative survey of the state of the art of research on gas-surface interactions. It provides an overview of the current understanding of gas surface dynamics and, in particular, of the reactive and non-reactive processes of atoms and small molecules at surfaces. Leading scientists in the field, both from the theoretical and the experimental sides, write in this book about their most recent advances. Surface science grew as an interdisciplinary research area over the last decades, mostly because of new experimental technologies (ultra-high vacuum, for instance), as well as because of a novel paradigm, the ‘surface science’ approach. The book describes the second transformation which is now taking place pushed by the availability of powerful quantum-mechanical theoretical methods implemented numerically. In the book, experiment and theory progress hand in hand with an unprecedented degree of accuracy and control. The book presents how modern surface science targets the atomic-level understanding of physical and chemical processes at surfaces, with particular emphasis on dynamical aspects. This book is a reference in the field.

Book Description
Fundamentals of Gas–Surface Interactions presents the study of the surface itself and the study of the gas phase partner of the interaction in which physical or chemical transformation of the gas resulted from that interaction. This book discusses the study of the energy and momentum exchanges resulting from the gas–solid physical interaction in which either gas or solid phase properties can be measured. Organized into three parts encompassing 33 chapters, this book begins with an overview of the different sensitive physical methods for the study of surface topography, surface defects, and surface irregularities to an accuracy of a few Angstroms. This text then reviews the adsorption at very low coverage that has yielded to equilibrium analysis. Other chapters consider the measurement of surface area by adsorption and optical techniques. The final chapter deals with scattering processes including momentum and energy transfer. This book is a valuable resource for engineers.

Book Description
The roles played by kinetic theory and gas-surface interactions in the interpretation of measurements made by mass spectrometers, pressure gauges, and satellite drag are discussed. The effect of adsorption is analyzed in detail. A resolution of the discrepancies between drag and instrumental measurements is proposed, taking into account the corrections for adsorption, gauge calibration, and chemical reactions of atomic oxygen.

Book Description
This book provides a comprehensive overview of what is currently one of the most active areas within chemical physics. It presents the history, status and future direction of the broad field of dynamical studies of gas-surface collisions, with an emphasis on problems of a chemical nature. Dynamics of Gas-Surface Interactions discusses a selection of important topics and provides a balanced picture of the whole field. It is written by experts in the respective subjects and no previous volume has offered such detailed coverage. This book will provide a valuable introduction to the subject for final year undergraduates and graduate students, as well as an important reference work for all those involved in this exciting area.

Book Description
Dynamics of Gas-Surface Scattering deals with the dynamics of scattering as inferred from known properties of gases and solids. This book discusses measurements of spatial distributions of scattered atomic and molecular streams, and of the energy and momentum which gas particles exchange at solid surfaces. It also considers two regimes of scattering, both of which are associated with a lower range of incident gas energies: the thermal and structure scattering regimes. Comprised of 10 chapters, this book opens with a brief historical overview of the early experiments that investigated the dynamics of scattering of gases by surfaces. The discussion then turns to some elements of the kinetic theory of gases; intermodular potentials and interaction regimes; and classical-mechanical lattice models used in gas-surface scattering theory. The applications of molecular beams to the study of gas-surface scattering phenomena are also described. The remaining chapters focus on experiments and theories on scattering of molecular streams by surfaces of solids, with emphasis on thermal and structure regimes of inelastic scattering; quantum theory of gas-surface scattering; and quantum mechanical scattering phenomena. This text concludes with an analysis of energy exchange processes that may occur when a solid surface is completely immersed in a still gas. This monograph will be a valuable resource for students and practitioners of physics, chemistry, and applied mathematics.

Book Description
The book contains papers presented at the 24th International Symposium on Rarefied Gas Dynamics, a conference that is recognized as the principal forum for the presentation of recent advances in the field of rarefied gas dynamics. The topics include fundamental aspects of Boltzmann and related equations, transport theory, Monte Carlo methods, kinetic theory, gas phase molecular collision dynamics, gas surface interaction, state to state kinetics, rarefied plasmas, and non-equilibrium plasma kinetics. Applications in the fields of internal flows, vacuum systems, rarefied jets, plumes, molecular beams, scamjets and hypersonics, microflows, granular gases, electrical thrusters are discussed. Researchers in the fields of mathematics, physics, chemistry and engineering can strongly benefit from the interdisciplinary nature of the book.
