Book Synopsis Fundamental Aspects of Plasma Chemical Physics by : Mario Capitelli
Download or read book Fundamental Aspects of Plasma Chemical Physics written by Mario Capitelli and published by Springer Science & Business Media. This book was released on 2015-11-26 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describing non-equilibrium "cold" plasmas through a chemical physics approach, this book uses the state-to-state plasma kinetics, which considers each internal state as a new species with its own cross sections. Extended atomic and molecular master equations are coupled with Boltzmann and Monte Carlo methods to solve the electron energy distribution function. Selected examples in different applied fields, such as microelectronics, fusion, and aerospace, are presented and discussed including the self-consistent kinetics in RF parallel plate reactors, the optimization of negative ion sources and the expansion of high enthalpy flows through nozzles of different geometries. The book will cover the main aspects of the state-to-state kinetic approach for the description of nonequilibrium cold plasmas, illustrating the more recent achievements in the development of kinetic models including the self-consistent coupling of master equations and Boltzmann equation for electron dynamics. To give a complete portrayal, the book will assess fundamental concepts and theoretical formulations, based on a unified methodological approach, and explore the insight in related scientific problems still opened for the research community.
Book Synopsis Kinetics of Nonequilibrium Low-Temperature Plasmas by : Leon Mikhaĭlovich Biberman
Download or read book Kinetics of Nonequilibrium Low-Temperature Plasmas written by Leon Mikhaĭlovich Biberman and published by Springer. This book was released on 1987-09-30 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first research on plasma was done in connection with the study of electrical discharges in gases. The focus of attention for physicists was the partially ionized plasma, the kinetics of which is governed by various collisional and radiative processes. The choice of this area of research was motivated largely by the practical problems of that time the creation of gas-discharge light sources, rectifiers, and inverters. Since the early 1950s interest in plasma physics has risen sharply, particularly in the study of the completely ionized plasma with its various collective phenomena, insta bilities, and the interesting and sometimes unexpected effects attending the propagation of electromagnetic waves in such a plasma and the action on it of external electric and magnetic fields. Interest in hot plasmas has been stimulated not only by the diverse and novel physical phenomena, but also by the problems arising in connection with controlled nuclear fusion. The advent, in the early 1960s, of new technical fields such as gas-discharge lasers, magnetohydrodynamic generators, thermoemission converters, plasma chemistry, plasma propul sion devices, various methods in plasma technology, etc. , has led to increased interest in weakly ionized low-tempera ture plasmas. This is particularly true of nonequilibrium plasmas, which are characterized by an extraordinary diver sity of states and properties.
Book Synopsis Plasma Catalysis by : Annemie Bogaerts
Download or read book Plasma Catalysis written by Annemie Bogaerts and published by MDPI. This book was released on 2019-04-02 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.

Book Synopsis Kinetics and Spectroscopy of Low Temperature Plasmas by : Jorge Loureiro
Download or read book Kinetics and Spectroscopy of Low Temperature Plasmas written by Jorge Loureiro and published by Springer. This book was released on 2016-06-22 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a comprehensive textbook designed for graduate and advanced undergraduate students. Both authors rely on more than 20 years of teaching experience in renowned Physics Engineering courses to write this book addressing the students’ needs. Kinetics and Spectroscopy of Low Temperature Plasmas derives in a full self-consistent way the electron kinetic theory used to describe low temperature plasmas created in the laboratory with an electrical discharge, and presents the main optical spectroscopic diagnostics used to characterize such plasmas. The chapters with the theoretical contents make use of a deductive approach in which the electron kinetic theory applied to plasmas with basis on the electron Boltzmann equation is derived from the basic concepts of Statistical and Plasma Physics. On the other hand, the main optical spectroscopy diagnostics used to characterize experimentally such plasmas are presented and justified from the point of view of the Atomic and Molecular Physics. Low temperature plasmas (LTP) are partially ionized gases with a broad use in many technological applications such as microelectronics, light sources, lasers, biology and medicine. LTPs lead to the production of atomic and molecular excited states, chemically reactive radicals, and activated surface sites, which are in the origin, among others, of the deposition of thin films, advanced nanotechnology products, solar cells, highly efficient combustion motors, and treatment of cancer cells.

Book Synopsis Nonequilibrium Vibrational Kinetics by : Mario Capitelli
Download or read book Nonequilibrium Vibrational Kinetics written by Mario Capitelli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the systematic treatment of nonequi 1 ibrium vibrational kinetics in molecular systems. Particular emphasis is given to the vibrational excitation of diatomic molecules by low-energy electrons in a discharge and by IR photons in laser-pumped systems. The book follows the different steps of the introduction, redistribution, loss, and chemical conversion of the vibrational quanta, from the points of view of the overall kinetics and the dynamics of elementary processes. These two aspects are balanced in a multidisciplinary approach. The different chapters give the basic instruments (theoretical and experimental) which are needed to understand the ki netics of nonequilibrium systems. The book will introduce the reader to different areas such as plasmachemistry, laser chemistry, IR and Raman spectroscopy, and relaxation phenomena, emphasizing how the vibrational energy affects such research fields. The chapters dedicated to collisional dynamics involving vibrational excited molecules provide an introduc tion to the modern techniques uti 1 ized in the scattering theory of inelastic and reactive collisions. The extension of the vibrational kinetics to polyatomic mole cules, discussed in Chap. 10, is the natural bridge between coll ision and coll i sionless regimes. In conclusion, we hope that the approach followed in this book will stimulate the collaboration of researchers coming from different research fields, which are too often completely separate.

Book Synopsis Electron Kinetics and Applications of Glow Discharges by : Uwe Kortshagen
Download or read book Electron Kinetics and Applications of Glow Discharges written by Uwe Kortshagen and published by Springer. This book was released on 2006-04-11 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book resulted from the NATO Advanced Research Workshop on “Electron Kinetics and Applications of Glow Discharges,” held in St. Petersburg, Russia, on May 19-23, 1997. Glow discharges have found widespread applications in many technological processes from the manufacture of semiconductors, to recent developments in na- technology, to the traditional fields of gas lasers, and discharge lamps. Consequently, the interest in the physics of glow discharges has experienced yet another resurgence of interest. While the non-equilibrium character of glow discharges is widely accepted, the opinion still prevails that the main features can be captured by fluid models, and that kinetic treatments are only required for the understanding of subtle details. The erroneousness of this belief is demonstrated by the failure of fluid models to describe many basic features of glow discharges such as, for instance, electrode phenomena, striations, and collisionless heating effects. An adequate description of glow discharges thus has to be of kinetic nature.
