One of the few textbooks in the field, this volume deals with several aspects of the dynamics of colloids. A self-contained treatise, it fills the gap between research literature and existing books for graduate students and researchers. For readers with a background in chemistry, the first chapter contains a section on frequently used mathematical techniques, as well as statistical mechanics. Some of the topics covered include: • diffusion of free particles on the basis of the Langevin equation •the separation of time, length and angular scales; • the fundamental Fokker-Planck and Smoluchowski equations derived for interacting particles • friction of spheres and rods, and hydrodynamic interaction of spheres (including three body interactions) • diffusion, sedimentation, critical phenomena and phase separation kinetics • experimental light scattering results. For universities and research departments in industry this textbook makes vital reading.

Interfacial Separation of Particles is concerned with the processing and separation of fine solid particles in liquid solutions using interfacial technology. Interfacial separation has been finding wide application in many industrial fields, such as pigment and filler production, mineral processing, environmental protection, hydrometallurgy, bioengineering, food and beverage industry and chemical industry. This book describes all interfacial separation techniques and discusses the general and specific fundamentals of the techniques. The book intends to promote theoretical understanding and the more promising developments of interfacial separation technology whilst broadening the reader's background knowledge of industrial suspensions. * Is clearly written based on strong systematic science fundamentals * Provides comprehensive coverage on particle technology, mineral processing and water treatment * Includes practical examples from the different industrial fields
Integrating fundamental research with the technical applications of this rapidly evolving field, Structure and Functional Properties of Colloidal Systems clearly presents the connections between structure and functional aspects in colloid and interface science. It explores the physical fundamentals of colloid science, new developments of synthesis and conditioning, and many possible applications. Theory Divided into three parts, the book begins with a discussion of the theoretical side of colloid dynamics. It then transitions to dynamically arrested states and capillary forces in colloidal systems at fluid interfaces. Structure Covering the structural aspects of different colloidal systems, the second section examines electric double layers and effective interactions as well as the structure of extremely bimodal suspensions and filaments made up of microsized magnetic particles. The contributors analyze the role played by the attractive interaction, confinement, and external fields on the structure of colloidal systems. They also discuss structural aspects in food emulsions and the rheological properties of structured fluids. Functional Materials The last part focuses on examples of functional colloids. These include polymer colloids, protein-functionalized colloidal particles, magnetic particles, metallic nanoparticles, micro- and nanogels, responsive microgels, colloidal photonic crystals, microfluidics, gel-glass dispersed liquid crystals (GDLCs) devices, and nanoemulsions. This volume provides a sound understanding of the link between the structure and functional properties in two- and three-dimensional colloidal systems. It describes techniques to functionalize colloids, characterization methods, the physical fundamentals of structure formation, diffusion dynamics, transport properties in equilibrium, the physical fundamentals of nonequilibrium systems, the measuring principles to exploit properties in applications, the differences in designing lab experiments and devices, and several application examples.
This book describes in detail the scientific philosophy of the formation and stabilization-destabilization of foams. It presents all hierarchical steps of a foam, starting from the properties of adsorption layers formed by foaming agents, discussing the properties of foam films as the building blocks of a foam, and then describing details of real foams, including many fields of application. The information presented in the book is useful to people working on the formulation of foams or attempting to avoid or destruct foams in unwanted situations.

In 1976, on the occasion of the Centennial of the Ameri can Chemical Society, H. A. RESrnG and C. G. WADE organized an international symposium on magnetic resonance in collo1d and in terface science which brought together a large number of scien tists from the United States and from abroad. The aim of this symposium was to include all experimental inorganic, organic and biochemical systems in which molecules are bound to interfaces and to show the contribution of various techniques based on ma gnetic resonance to the knowledge of these systems. This ambi tious program resulted into a very interesting gathering that initiated a more interdisciplinary approach to the problem of interfaces. Because of the success of this symposium it was sug gested that a similar meeting should be organized in Europe within the next three years. Professor J. FRAISSARD accepted this task but, conside ring the rapid developments in the theory and in the applica tions of the magnetic resonance spectroscopies, the organ1z1ng committee decided to arrange the meeting to be held in MENTON (France) in two parts, the first being a School and the second the Symposium proper. The former was' intended to review and to teach theoretical aspects as well as to discuss the experimental results derived from these advanced methods; the Symposium was to be for the discussion of the latest results at the highest level.
As the first of its kind, this book provides a valuable introduction for scientists and engineers interested in liquid/fluid interfaces and disperse systems to the rapidly developing area of adsorption dynamics. It is the first extensive review available on the subject of dynamics of adsorption and gives a general summary of the current state of adsorption kinetics theory and experiments. Current progress in recently designed set-ups and improved and generalised known methods for studying interfacial relaxations is reviewed. In addition, the role of the electric charge of surfactants in the adsorption process is discussed in terms of a non-equilibrium distribution of adsorbing ions in the diffuse layer. Present theories of the effect of dynamic adsorption layers on mobile surfaces, such as moving drops and bubbles, based on both diffusion and kinetic controlled adsorption models are described and efficient approximate analytical methods to solve the mathematical problem of coupling surfactant transport and hydrodynamics are introduced. The role of a dynamic adsorption layer in bubble rising, film drainage and film stabilisation and in complex processes such as flotation and microflotation is discussed. Containing more than 1100 references, the book is essential reading for industrial scientists and graduate and post-graduate students in physical, surface and colloid chemistry, physico-chemical hydrodynamics, water purification and mineral processing.
