Thermodynamics Of Non Equilibrium Processes For Chemists With A Particular Application To Catalysis

Thermodynamics of Non-Equilibrium Processes for Chemists with a Particular Application to Catalysis consists of materials adapted from lectures on the thermodynamics of nonequilibrium processes that have been taught at the Department of Natural Sciences of Novosibirsk State University since 1995. The thermodynamics of nonequilibrium processes traditionally required students to have a strong background in physics. However, the materials featured in this volume allow anyone with knowledge in classical thermodynamics of equilibrium processes and traditional chemical kinetics to understand the subject. Topics discussed include systems in the thermodynamics of irreversible processes; thermodynamics of systems that are close to and far from equilibrium; thermodynamics of catalysts; the application of nonequilibrium thermodynamics to material science; and the relationship between entropy and information. This book will be helpful for research into complex chemical transformations, particularly catalytic transformations. Applies simple approaches of non-equilibrium thermodynamics to analyzing properties of chemically reactive systems Covers systems far from equilibrium, allowing the consideration of most chemically reactive systems of a chemical or biological nature This approach resolves many complicated problems in the teaching of chemical kinetics

Nonequilibrium Processes in Catalysis presents modern ideas and experimental data (e.g., molecular beams, laser technique) on adsorption and catalysis, the mechanism of energy exchange in the processes of particles interaction with a surface, and the lifetimes of excited particles on a surface. Previously unpublished theoretical information regarding the principle of chemoenergetical stimulation accounting for the acceleration of one reaction at the expense of reactant excitation in another is provided, and new ideas about nonequilibrium surface diffusion are explored. Examples of the formation of nonequilibrium dissipative structures in catalysis are presented, including auto-oscillations, auto-waves, multiplicity of kinetic regimes, nonequilibrium phase transition, and decelerated electron exchange between solid and adsorbed species. The book also describes new experimental methods for studying nonequilibrium and quick processes in catalysis. Nonequilibrium Processes in Catalysis will benefit physicists involved with surface science, chemists involved with adsorption and catalysis, engineers, vacuum scientists, physical chemists, materials chemists, students, and others interested in these processes.

This book is devoted to the problems of oxidation chemical reactions and addresses bimodal reaction sequences. Chemical reactions of oxidation, occurring under certain conditions and in multicomponent systems are complex processes. The process of the oxidation essentially changes in the presence and contact of the solid substances with reactants. The role of solid substances and the appearance of this phenomenon in oxidation reaction are discussed. The reader will understand the "driving forces" of this phenomenon and apply it in practice. Written for chemists, physicists, biologists and engineers working in the domain of oxidation reactions. Key Selling Features: Covers the historical background, modern state of the art, and perspectives in investigations of the coupling between heterogeneous and homogeneous reactions Discusses the feasible pathways of the coupling of heterogeneous and homogeneous reactions in oxidation in man-made and natural chemical systems Addresses the abundance, peculiarities and mechanisms of the bimodal reaction sequences in oxidation with dioxygen in recent decades Discusses the existence of the bimodal reaction sequences in chemical systems investigations in atmospheric chemistry and heterogeneous photocatalysis Presented in a simple concise style, accessible for both specialists and non-specialists

This book focuses on the triboemission of low-energy electrons from the freshly generated surface. These electrons play the most crucial role in the chemical reactions at the tribological interface. New models and TIP (thermodymanics of irreversible processes) describe in detail the behavior of emitted electrons which lower the activation energy of the chemical reactions. This book also highlights tribocatalysis phenomena as examples of the lowering of the activation energy. A book titled Tribocatalysis has never been published before this.

There is an increasing need to find cost-effective and environmentally sound methods of converting natural resources into fuels, chemicals and energy; catalysts are pivotal to such processes. Catalysis highlights major developments in this area. Coverage of this Specialist Periodical Report includes all major areas of heterogeneous catalysis. n each volume, specific areas of current interest are reviewed. Examples of topics include experimental methods, acid/base catalysis, materials synthesis, environmental catalysis, and syngas conversion.

He shows direct and inverse links between foundations of science and new theories and empirical facts evolved from those, how among many potentially possible histories of science a culture selects just those directions which become a real history of science. The author analyses mechanisms of the generation of scientific theories and shows that those are changed in the process of historical development of science. He displays three historical types of scientific rationality (classical, non-classical and post-non-classical, which appears in modern science) and shows features of their coexistence and interplay. It is shown that along with the emerging of post-non-classical rationality science increases the sphere of its worldview applications. Science begins to correlate not only with the basic values of technogenic civilization but also with some values and patterns of traditional cultures.

The purpose of this book is to encourage the use of non-equilibrium thermodynamics to describe transport in complex, heterogeneous media. With large coupling effects between the transport of heat, mass, charge and chemical reactions at surfaces, it is important to know how one should properly integrate across systems where different phases are in contact. No other book gives a prescription of how to set up flux equations for transports across heterogeneous systems.The authors apply the thermodynamic description in terms of excess densities, developed by Gibbs for equilibrium, to non-equilibrium systems. The treatment is restricted to transport into and through the surface. Using local equilibrium together with the balance equations for the surface, expressions for the excess entropy production of the surface and of the contact line are derived. Many examples are given to illustrate how the theory can be applied to coupled transport of mass, heat, charge and chemical reactions; in phase transitions, at electrode surfaces and in fuel cells. Molecular simulations and analytical studies are used to add insight.

This book gathers perspectives, applications, and developments in the extensively researched fields of chemical kinetics and catalysis. Catalysis is a key component of modern industry advancements ranging from production to energy and environmental sustainability, and chemical kinetics offers important information about a reaction. In addition to discussing redox processes, kinetics, and density functional theory, this book bridges the gap between the worlds of enzymes and electric fields and focuses on the shortcomings of transition state theory (TST).

Any good text book,particularly that in the fast changing fields such as engineering & technology,is not only expected to cater to the current curricular requirments of various institutions but also should provied a glimplse towards the latest developments in the concerned subject and the relevant disciplines.It should guide the periodic review and updating of the curriculum.
