Physics of Surface, Interface and Cluster Catalysis reviews the fundamental physics of catalysis from simple surface models through to complex cluster and catalytic structures. It is the first book to provide a coherent collection of the physics of catalysis, and shows how physics has provided and continues to provide clarity and insight into many complex catalysis problems, reviewing both recent developments and prospects for future developments in the field.
This graduate-level textbook covers the major developments in surface sciences of recent decades, from experimental tricks and basic techniques to the latest experimental methods and theoretical understanding. It is unique in its attempt to treat the physics of surfaces, thin films and interfaces, surface chemistry, thermodynamics, statistical physics and the physics of the solid/electrolyte interface in an integral manner, rather than in separate compartments. It is designed as a handbook for the researcher as well as a study-text for graduate students. Written explanations are supported by 350 graphs and illustrations.
This book is dedicated to recent advancements in theoretical and computational studies on the interactions of hydrogen and hydrogenated molecules with metal surfaces. These studies are driven by the development of high-performance computers, new experimental findings, and the extensive work of technological applications towards the realization of a sustainable hydrogen economy. Understanding of the elementary processes of physical and chemical reactions on the atomic scale is important in the discovery of new materials with high chemical reactivity and catalytic activity, as well as high stability and durability. From this point of view, the book focuses on the behavior of hydrogen and hydrogenated molecules on flat, stepped, and reconstructed metal surfaces. It also tackles the quantum mechanical properties of hydrogen and related adsorbates; namely, molecular orbital angular momentum (spin) and diffusion along the minimum potential energy landscape on metal surfaces. All of these profoundly influence the outcomes of (1) catalytic reactions that involve hydrogen; (2) hydrogen storage in metals; and (3) hydrogen purification membranes. Lastly, it surveys the current status of the technology, outlook, and challenges for the long-desired sustainable hydrogen economy in relation to the topics covered in the book.

Heterophase polymerization is a century-old technology with a wide range of relevant industrial applications, including coatings, adhesives, rubbers, and many other specialized biomedical and high-performance materials. However, due to its multiscale complexity, it still remains a challenging research topic. It is a broad field covering all heterogeneous polymerization processes that result in polymer dispersions. Its technical realizations comprise emulsion polymerization, dispersion polymerization, suspension polymerization, miniemulsion polymerization, microemulsion polymerization, and others. This book is devoted to the science and technology of heterophase polymerization, considering it a generic term as well as an umbrella expression for all of its technical realizations. It presents, from a modern perspective, the basic concepts and principles required to understand the kinetics and thermodynamics of heterophase polymerization at the atomistic, molecular, macromolecular, supramolecular, colloidal, microscopic, mesoscopic, and macroscopic scales. It critically discusses the important physicochemical mechanisms involved in heterophase polymerization, such as nucleation, particle aggregation, mass transfer, swelling, spontaneous emulsification, and polymerization kinetics, along with the experimental evidences at hand.
of available information. Even more importantly, some authors who have contributed substantially to an area may have been overlooked. For this I apologize. I have, however, not attempted to trace techniques or observa tions historically, so there is no implication (unless specified) that the authors referred to were or were not the originators of a given method or observation. I would like to acknowledge discussions with co-workers at SFU for input relative to their specialties, to acknowledge the help of students who have pointed out errors and difficulties in the earlier presentation, and to acknowledge the infinite patience of my wife Phyllis while I spent my sabbatical and more in libraries and punching computers.

Illustrating developments in electrochemical nanotechnology, heterogeneous catalysis, surface science and theoretical modelling, this reference describes the manipulation, characterization, control, and application of nanoparticles for enhanced catalytic activity and selectivity. It also offers experimental and synthetic strategies in nanoscale surface science. This standard-setting work clariefies several practical methods used to control the size, shape, crystal structure, and composition of nanoparticles; simulate metal-support interactions; predict nanoparticle behavior; enhance catalytic rates in gas phases; and examine catalytic functions on wet and dry surfaces.
* At the present stage of development of surface science, there has seemed to be a need for a book-length review spanning the disciplines of surface physics and surface chemistry-a review to summarize and show the con nection between the observations from each discipline. The various results and theories, derived on the one hand from studies of the physical, electronic, and optical properties of surfaces and on the other hand from studies of the chemical activity of surfaces, supplement each other in the search for a realistic model of the surface. The improved understanding possible with such an interdisciplinary approach has been confirmed by recent develop ments which cannot be classified as either surface chemistry or surface physics. Specifically, recent new experimental techniques and quantum mechanical models have provided a much more accurate picture of the nature of the electronic energy levels (bonding orbitals) present at a solid surface. With this more accurate picture we are now able to reconcile the various chemical and physical models that appeared in the early literature on surfaces. The objective of this work has therefore been to describe the results and current models of surface science spanning a broad gray area between surface physics and surface chemistry with some overlap into each of these disciplines. Relevant aspects of surface chemistry are discussed; we cover chemical interactions where bonding and electronic properties dominate, but stop short of specialized topics such as surfactants or liquid/liquid interfaces.
This book deals with the evolution of the properties of clusters, nanostructures and cluster-based materials, with emphasis on the role of the interface. These materials are characterized by reduced size, dimension and symmetry, and possess many novel properties that are not commonly seen in their bulk phases. The topics include synthesis, nucleation, growth, characterization, atomic and electronic structure, dynamics, ultra-fast spectroscopy, stability; electrical, magnetic, optical, thermodynamic and catalytic properties of clusters (free and supported); cluster materials (self-assembled, ligated and embedded); nanostructures (quantum dots, wells and corrals; nanotubes and wires; colloidal and biological materials) and nano-technology (electronic, magnetic and optical devices). In addition to presenting the current status of the field, the book discusses outstanding problems and future directions.
