Download or read book Atom Resolved Surface Reactions written by Philip Rosser Davies and published by Royal Society of Chemistry. This book was released on 2008 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a unique perspective of the impact of scanning probe microscopies on our understanding of the chemistry of the surface at the nanoscale. Research oriented, with the concepts gleaned from Scanning Tunnelling Microscopy being related to the more established and accepted views in surface chemistry and catalysis the authors have addresses the question "How do the models based on classical spectroscopic and kinetic studies stand up to scrutiny at the atom - resolved level?". In taking this approach the reader, new to the field of surface chemistry, should be able to obtain a perspective on how the evidence from STM confirms or questions long standing tenets. An emphasis is given to "how did we get to where we are now" and a large number of figures from the literature are included along with suggestions for further reading. Topics discussed include: - the dynamics of oxygen chemisorption at metal surfaces - control of oxygen states and surface reconstruction - dissociative chemisorption of diatomic and hydrocarbon molecules - nanoparticles and chemical reactivity - STM at high pressures - structural studies of sulfur containing molecules and molecular templating This book will appeal to all those who wish to become familiar with the contribution Scanning Tunnelling Microscopy has made to the understanding of the field of surface chemistry and heterogeneous catalysis and also to those who are new to catalysis, a fascinating and important area of chemistry.
Download or read book Mineral Surface Reactions at the Nanoscale written by Christine V. Putnis and published by MDPI. This book was released on 2019-05-20 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reactions at mineral surfaces are central to all geochemical processes. As minerals comprise the rocks of the Earth, the processes occurring at the mineral–aqueous fluid interface control the evolution of the rocks and hence the structure of the crust of the Earth during processes such as metamorphism, metasomatism, and weathering. In recent years focus has been concentrated on mineral surface reactions made possible through the development of advanced analytical methods such as atomic force microscopy (AFM), advanced electron microscopies (SEM and TEM), phase shift interferometry, confocal Raman spectroscopy, and advanced synchrotron-based applications, to enable mineral surfaces to be imaged and analyzed at the nanoscale. Experiments are increasingly complemented by molecular simulations to confirm or predict the results of these studies. This has enabled new and exciting possibilities to elucidate the mechanisms that govern mineral–fluid reactions. In this Special Issue, “Mineral Surface Reactions at the Nanoscale”, we present 12 contributions that highlight the role and importance of mineral surfaces in varying fields of research.
Download or read book An Introduction to Kinetic Monte Carlo Simulations of Surface Reactions written by A.P.J. Jansen and published by Springer. This book was released on 2012-05-31 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kinetic Monte Carlo (kMC) simulations still represent a quite new area of research, with a rapidly growing number of publications. Broadly speaking, kMC can be applied to any system describable as a set of minima of a potential-energy surface, the evolution of which will then be regarded as hops from one minimum to a neighboring one. The hops in kMC are modeled as stochastic processes and the algorithms use random numbers to determine at which times the hops occur and to which neighboring minimum they go. Sometimes this approach is also called dynamic MC or Stochastic Simulation Algorithm, in particular when it is applied to solving macroscopic rate equations. This book has two objectives. First, it is a primer on the kMC method (predominantly using the lattice-gas model) and thus much of the book will also be useful for applications other than to surface reactions. Second, it is intended to teach the reader what can be learned from kMC simulations of surface reaction kinetics. With these goals in mind, the present text is conceived as a self-contained introduction for students and non-specialist researchers alike who are interested in entering the field and learning about the topic from scratch.

Download or read book Kinetics of Interface Reactions written by Michael Grunze and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the first Workshop on Interface Phenomena, organized jointly by the surface science groups at Dalhousie University and the University of Maine. It was our intention to concentrate on just three topics related to the kinetics of interface reactions which, in our opinion, were frequently obscured unnecessarily in the literature and whose fundamental nature warranted an extensive discussion to help clarify the issues, very much in the spirit of the Discussions of the Faraday Society. Each session (day) saw two principal speakers expounding the different views; the session chairmen were asked to summarize the ensuing discussions. To understand the complexity of interface reactions, paradigms must be formulated to provide a framework for the interpretation of experimen tal data and for the construction of theoretical models. Phenomenological approaches have been based on a small number of rate equations for the concentrations or mole numbers of the various species involved in a par ticular system with the relevant rate constants either fitted (in the form of the Arrheniusparametrization) to experimental data or calculated on the basis of microscopic models. The former procedure can at best serve as a guide to the latter, and is, in most cases, confined to ruling out certain reaction pathways rather than to ascertaining a unique answer.

Download or read book Kinetics of Multistep Reactions written by Friedrich G. Helfferich and published by Elsevier. This book was released on 2004-09-15 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses primarily the engineer in industrial process development, the research chemist in academia and industry, and the graduate student intending to become a reaction engineer. In industry, competitive pressures put a premium on scale-up by large factors to cut development time. To be safe, such development should be based on "fundamental" kinetics that reflect the elementary steps of which the reaction consists. The book forges fundamental kinetics into a practical tool by presenting new, effective methods for elucidation of mechanisms and reduction of complexity without unacceptable sacrifice in accuracy: fewer equations (lesser computational load), fewer coefficients (fewer experiment to determine them). For network elucidation, new rules relating network configurations to observable kinetic behaviour allow incorrect networks to be ruled out by whole classes instead of one by one. For modelling, general equations and algorithms are given from which equations for specific networks can be recovered by simple substitutions. The procedures are illustrated with examples of industrial reactions including, among others, paraffin oxidation, ethoxylation, hydroformylation, hydrocyanation, shape-selective catalysis, ethane pyrolysis, styrene polymerization, and ethene oligomerization. Many of the rate equations have not been published before. The expanded edition of the 2001 title, Kinetics of Homogeneous Multistep Reactions includes new chapters on heterogeneous catalysis and periodic and chaotic re-actions; new sections on adsorption, statistical methods, and lumping; and other new detail. Contains new chapters on heterogeneous catalysis, oscillations and chaos Includes new sections on statistical methods, lumping adsorption and software and databases Provides a better understanding of complex reaction mechanisms

Book excerpt: Adverse immune reactions to biomaterials are important bottlenecks for translation of novel biomaterials for clinical use. Moreover, recent advances in highthrough-put biomaterial discovery and synthetic biology, while providing exciting new veues, also significantly increases potential risks related to the in vivo reactions to these new materials. For example, the novel materials might have unintended biological activities due to their natural building blocks. In this perspective, biomaterial field needs i) better understanding of cell/biomaterial interactions at systems level; ii) development of new analysis and testing tools for advanced risk assessment iii) tools and technologies for modulating reactions to biomaterials and iv) advanced in vitro models for understanding and testing of reactions to biomaterials. In the following collection of articles you will find examples of such systems,together with comprehensive reviews of current developments in in vitro model systems. The collection also contains articles that elucidate the immune reaction to biomaterials in vitro and in vitro.

The topic is followed by an overview of the main classes of catalytic reactions that have been studied over evaporated metal film catalysts. A chapter explores the preparation, characterization, structure, and surface properties of alloy films. The theory of the oxidation of metals and the advantages and disadvantages of using thin metal films in oxidation work are considered in the concluding chapter, along with a brief discussion on their use in kinetic and mechanistic studies. Research scientists and graduate students who are interested in the fundamentals of adsorption and catalysis will find this volume invaluable.
Download or read book Feldspars and their Reactions written by Ian Parsons and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feldspar minerals make up 60% of the crust of the Earth. They are stable in the upper mantle, and are so abundant in the crust that they form the basis of the classification of igneous rocks. At the surface, feldspars weather to form clay minerals which are the most important mineral constituent of soils. The articles in this book review the chemical reactions of feldspars over the whole sweep of pressure and temperature regimes in the outer Earth, and describe the fundamental aspects of crystal structure which underlie their properties. The book covers intracrystalline reactions, such as order-disorder transformations and exsolution, and transfer of stable and radiogenic isotopes, which can be interpreted to provide insights into the thermal history of rocks. It is suitable for final year undergraduates or research workers.
