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.

Book excerpt: The first Workshop of Interface Phenomena concentrated on just three topics related to the kinetics of interface reactions: (1) adsorption-desorption kinetics, (2) precursors, (3) kinetics and phase transitions. The adsorption and desorption processes themselves are to be understood as surface bond making and breaking mechanisms, respectively. If the energy transfer is fast enough, then these processes can be understood in terms of thermodynamic arguments such as formulated in transition state theory. However, in most situations such as simple treatment is not sufficient and the details of the microscopic dynamics must be invoked. Unfortunately, this point is very frequently overlooked in the analysis of kinetic data of gas-surface reactions, leading to rather murky discussions in the literature. The phenomenological analysis of surface reactions in terms of kinetic rate equations quite often has to invoke precursor states as reaction intermediates to fit experimental data. However, because such an analysis rarely leads to a unique answer, independent evidence must be brought forward if precursors in a given reaction are to be accepted as more than just mythical mis-fits. The equilibrium properties of surface phase transitions have been studied for many decades, and they exhibit a wealth of fascinating detail. The exploration of their kinetics, on the other hand, had to await the advent of time resolved surface analysis techniques. In particular, video-LEED has made it possible to study kinetics of surface reconstruction.

Book excerpt: "Adhesion and Friction: Microscopic Concepts" was the theme of the third workshop on interface phenomena organized jointly by the surface science groups at Dalhousie University and the University of Maine. The first two workshops were dedicated to the discussion of elementary processes governing the reaction rates at surfaces and in bulk materials, i. e. adsorption, desorption and diffusion. In this third year a step towards the understanding of complicated (but practical) issues such as adhesion and friction between different materials was undertaken. The presentations and discussions focused on elementary chemical and physical processes at surfaces and interfaces relevant to adhesion, lubrication and friction and gave an account of the application of surface science methods and techniques to relevant model systems. Clearly, at the time of the conference and the publication of the proceedings the understanding of the chemical and physical mechanisms determining the interaction between two solids is still rudimentary, but the issues involved are attracting the attention of more and more scientists and are now regularly represented at scientific meetings. The conference was held at Dalhousie University in Halifax, Nova Scotia, Canada. The facilities provided an ideal setting for the meeting and lively discussions. On behalf of the participants, we would like to express our grat itude to the staff at Dalhousie University for making our stay so pleasant and memorable.

Book excerpt: Interfacial Phenomena examines the fundamental properties of various liquid interfaces. This book discusses the physics of surfaces; electrostatic and electrokinetic phenomena; and adsorption at liquid interfaces. The properties of monolayers; reactions at liquid surfaces; diffusion through interfaces; and disperse systems and adhesion are also deliberated. Other topics include the vapor pressures over curved surfaces; electrical capacity of the double layer; applications of electrophoresis; and thermodynamics of adsorption and desorption. The experimental methods of spreading films at the oil-water interface; penetration into monolayers; experiments on dynamic systems; and spontaneous emulsification are likewise covered in this text. This book is beneficial to chemical engineers and students concerned with interfacial phenomena.
