Download or read book Dynamic Chemical Processes on Solid Surfaces written by Ken-ichi Tanaka and published by Springer. This book was released on 2018-05-04 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the author determines that a surface is itself a new material for chemical reaction, and the reaction of the surface provides additional new materials on that surface. The revelation of that peculiarity is what makes this book different from an ordinary textbook, and this new point of view will help to provide a new impetus when graduate students and researchers consider their results. The reaction of surface atoms provides additional new compounds, but these compounds cannot be detached from the surface. Some compounds are passive, but others work as catalysts. One superior feature of the surface is the dynamic cooperation of two or more different functional materials or sites on the same surface. This fact has been well established in the preferential oxidation of CO on platinum supported on a carbon nanotube with Ni-MgO at its terminal end. The Pt and Ni-MgO are perfectly separated, but these two are indispensable for the selective oxidation of CO in H2, where the H2O molecule plays a key role. The reader will understand that the complexity of catalysis is due to the complexity of the dynamic processes on the surface.
Download or read book Mechanisms in Organic Reactions written by Richard A. Jackson and published by Royal Society of Chemistry. This book was released on 2004 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: An increasing knowledge and understanding of organic reaction mechanisms has been a major factor in the rapid advance of organic chemistry, biochemistry and pharmacology in the last century. It therefore forms a vital part of today's chemistry courses. Mechanisms in Organic Reactions helps students to make sensible proposals for the mechanisms of particular organic reactions, and then how to distinguish between different possible mechanisms. Techniques for this include product studies, kinetics, and the identification of intermediates. Three chapters on intermediates discuss likely points of attack on molecules by anions, radicals and cations, and the important role of acid- and base-catalysed reactions and radical chain reactions. The prediction of reaction rates and the effects of structural changes on reaction rate are also covered. It concludes with a discussion of molecular reactions, both thermal and photochemical - reactions which provide deep and beautiful insights into the reasons why some reactions go and others do not, and why the majority of real-life reactions involve multi-step processes. The book provides both illuminating insights into fundamental chemistry, and also practical value for students who will go on to teach, research, or be involved in other scientific roles (administration, policy making or journalism). Ideal for the needs of undergraduate chemistry students, Tutorial Chemistry Texts is a major series consisting of short, single topic or modular texts concentrating on the fundamental areas of chemistry taught in undergraduate science courses. Each book provides a concise account of the basic principles underlying a given subject, embodying an independent-learning philosophy and including worked examples.
Download or read book Chemical Triggering written by Gebran J. Sabongi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical reactions which can, on demand, be switched on and off are valuable for industrial applications. In order to make the best use ofthese reactions, it is essential to have them readily available for a research chemist. The chemical literature, in general, has not yet identified or grouped such reactions. However, their existence is relatively abundant. This book is meant as a survey ofthose reactions which have potential utility in industrially useful processes. These reactions are grouped under the title ofchemical release reactions which can be triggered by heat, light, electric current, etc., to release a specific compound from, or change in the physical or chemical properties of, a unimolecular reactant. The book is divided into chapters covering ways to trigger the release of certain chemicals. Each chapter is further divided into sections, each beginning with a brief introduction ofanalogies ofthe discussed reactions and of how they were used in reported industrial processes. This survey is not meant to be absolute or exhaustive but rather to be directive, to be as complete as possible, and to provide food for further thought.
Download or read book Misconceptions in Chemistry written by Hans-Dieter Barke and published by Springer Science & Business Media. This book was released on 2008-11-18 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decades several researchers discovered that children, pupils and even young adults develop their own understanding of "how nature really works". These pre-concepts concerning combustion, gases or conservation of mass are brought into lectures and teachers have to diagnose and to reflect on them for better instruction. In addition, there are ‘school-made misconceptions’ concerning equilibrium, acid-base or redox reactions which originate from inappropriate curriculum and instruction materials. The primary goal of this monograph is to help teachers at universities, colleges and schools to diagnose and ‘cure’ the pre-concepts. In case of the school-made misconceptions it will help to prevent them from the very beginning through reflective teaching. The volume includes detailed descriptions of class-room experiments and structural models to cure and to prevent these misconceptions.

Download or read book Electrochemical Reactions and Mechanisms in Organic Chemistry written by J. Grimshaw and published by Elsevier. This book was released on 2000-12-01 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrochemical reactions make significant contributions to organic synthesis either in the laboratory or on an industrial scale. These methods have the potential for developing more "green" chemical synthesis. Over recent years, modern investigations have clarified the mechanisms of important organic electrochemical reactions. Progress has also been made in controlling the reactivity of intermediates through either radical or ionic pathways. Now is the time to gather all the electrochemical work into a textbook. As an essential addition to the armory of synthetic organic chemists, electrochemical reactions give results not easily achieved by many other chemical routes. This book presents a logical development of reactions and mechanisms in organic electrochemistry at a level suited to research scientists and final year graduate students. It forms an excellent starting point from which synthetic organic chemists, in both academia and industry, can appreciate uses for electrochemical methods in their own work. The book is also a reference guide to the literature.

Download or read book Chemical Reactions written by Antonio Laganà and published by Springer. This book was released on 2018-01-17 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This graduate textbook, written by experienced lecturers, features the study and computation of efficient reactive processes. The text begins with the problem of determining the chemical reaction properties by first decomposing complex processes into their elementary components. Next, the problem of two colliding mass points is investigated and relationships between initial conditions and collision outcomes are discussed. The failure of classical approaches to match experimental information is discussed and a quantum formulation of the calculation of the properties of two colliding bodies is provided. The authors go onto describe how the formalism is extended to structured collision partners by discussing the methods used to compute the electronic structure of polyelectronic reactants and products and the formalism of atom diatom reactions. Additionally, the relationships between the features of the potential energy surface and the outcomes of the reactive dynamics, are discussed. Methods for computing quantum, classical, and semi-classical reactive probabilities based on the already discussed concepts and tools are also featured and the resulting main typical reactive behaviors are analyzed. Finally, the possibility of composing the computational tools and technologies needed to tackle more complex simulations as well as the various competences and distributed computing infrastructure needed for developing synergistic approaches to innovation are presented.
