Download or read book Fundamentals of Gas Surface Interactions written by Howard Saltsburg and published by Elsevier. This book was released on 2013-10-22 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The principal mechanisms of energy and momentum transfer between gas atoms and solid surfaces are considered for the range of impact energies encountered in high-speed flight (e.g., up to 10 ev). Included within are (1) introductory discussions of the nature of surfaces, intermolecular potentials, adsorption, and basic gas -surface interaction processes, (2) a critical survey of the definitions of energy and momentum accommodation coefficients, (3) summaries of existing theoretical and experimental results pertaining to the energy accommodation and directional distribution of atoms scattered from a surface, (4) an attempt to formulate the main parameters and regimes of gas-surface interactions, and (5) suggestions concerning future investigations.

Download or read book Interaction of Gases with Surfaces written by Alexander V. Bogdanov and published by Springer Science & Business Media. This book was released on 1995-03-22 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This paper describes some recent findings in the mechanics of gas-surface interaction, and some experimental techniques developed for their laboratory study. It stresses the exchange of energy and momentum at the surface and incidentally suggests some of the molecular interactions which occur at orbital or entry velocities.
Download or read book Surface Science written by John Hudson and published by Elsevier. This book was released on 2013-10-22 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The whole field of surface science is covered in this work. Starting with a description of the structure and thermodynamics of clean surfaces, the book goes on to discuss kinetic theory of gases and molecular beam formation. This is followed by a largesection on gas-surface interactions, and another major section on energetic particle-surface interactions. The final chapter provides the background to crystal nucleation and growth. The approach adopted is interdisciplinary and slanted towards theexperimental side, with practical analytical techniques being used to illustrate general principles.
Download or read book The MEMS Handbook written by Mohamed Gad-el-Hak and published by CRC Press. This book was released on 2001-09-27 with total page 1386 pages. Available in PDF, EPUB and Kindle. Book excerpt: The revolution is well underway. Our understanding and utilization of microelectromechanical systems (MEMS) are growing at an explosive rate with a worldwide market approaching billions of dollars. In time, microdevices will fill the niches of our lives as pervasively as electronics do right now. But if these miniature devices are to fulfill their mammoth potential, today's engineers need a thorough grounding in the underlying physics, modeling techniques, fabrication methods, and materials of MEMS. The MEMS Handbook delivers all of this and more. Its team of authors-unsurpassed in their experience and standing in the scientific community- explore various aspects of MEMS: their design, fabrication, and applications as well as the physical modeling of their operations. Designed for maximum readability without compromising rigor, it provides a current and essential overview of this fledgling discipline.
Download or read book Physics at Surfaces written by Andrew Zangwill and published by Cambridge University Press. This book was released on 1988-03-24 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physics at Surfaces is a unique graduate-level introduction to the physics and chemical physics of solid surfaces, and atoms and molecules that interact with solid surfaces. A subject of keen scientific inquiry since the last century, surface physics emerged as an independent discipline only in the late 1960s as a result of the development of ultra-high vacuum technology and high speed digital computers. With these tools, reliable experimental measurements and theoretical calculations could at last be compared. Progress in the last decade has been truly striking. This volume provides a synthesis of the entire field of surface physics from the perspective of a modern condensed matter physicist with a healthy interest in chemical physics. The exposition intertwines experiment and theory whenever possible, although there is little detailed discussion of technique. This much-needed text will be invaluable to graduate students and researchers in condensed matter physics, physical chemistry and materials science working in, or taking graduate courses in, surface science.

Download or read book Understanding Gas surface Interactions from Direct Force Measurements Using a Specialized Torsion Balance written by and published by . This book was released on 1996 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive measurements of the magnitude and direction of the forces exerted on surfaces by molecular beams are discussed and used to obtain information about the microscopic properties of the gas-surface interactions. This unique approach is not based on microscopic measurements of the scattered molecules. The reduced force coefficients are introduced as a new set of parameters that completely describe the macroscopic average momentum transfer to a surface by an incident molecular beam. By using a specialized torsion balance and molecular beams of N2, CO, CO2, and H2, the reduced force coefficients are determined from direct measurements of the force components exerted on surface of a solar panel array material, Kapton, SiO2-coated Kapton, and Z-93 as a function of the angle of incidence ranging from 0° to 85°. The absolute flux densities of the molecular beams were measured using a different torsion balance with a beam-stop that nullified the force of the scattered molecules. Standard time-of-flight techniques were used to determine the flux-weighted average velocities of the various molecular beams ranging from 1600 m/s to 4600 m/s. The reduced force coefficients can be used to directly obtain macroscopic average properties of the scattered molecules, such as the flux-weighted average velocity and translational energy, that can then be used to determine microscopic details concerning gas-surface interactions without the complications associated with averaging microscopic measurements.
