Dynamics of Surfactant Self-Assemblies - Micelles, Microemulsions, Vesicles and Lyotropic Phases (Paperback): Raoul Zana Dynamics of Surfactant Self-Assemblies - Micelles, Microemulsions, Vesicles and Lyotropic Phases (Paperback)
Raoul Zana
R2,057 Discovery Miles 20 570 Ships in 12 - 19 working days

Dynamics of Surfactant Self-Assemblies explains the dynamics of micellar equilibria, tracking surfactant exchange, and micelle formation/breakdown processes. Highlighting the structural similarities of amphiphilic block copolymers to surfactants, this volume elucidates the dynamics of more complex self-assemblies that surfactants and amphiphilic block copolymers form in solutions. The book first discusses self-assembling processes taking place in aqueous surfactant solutions and the dynamic character of surfactant self-assemblies. The next chapter reviews methods that permit the study of the dynamics of self-assemblies. The dynamics of micelles of surfactants and block copolymers, solubilized systems, microemulsions, vesicles, and lyotropic liquid crystals/mesophases are reviewed successively. The authors point out the similarities and differences in the behavior of these different self-assemblies. Much emphasis is put on the processes of surfactant exchange and of micelle formation/breakdown that determine the surfactant residence time in micelles, and the micelle lifetime. The last three chapters cover topics for which the dynamics of surfactant self-assemblies can be important for a better understanding of observed behaviors: dynamics of surfactant adsorption on surfaces, rheology of viscoelastic surfactant solutions, and kinetics of chemical reactions performed in surfactant self-assemblies used as microreactors. Dynamics of Surfactant Self-Assemblies offers a unique and comprehensive review of the literature that exists on the dynamics of the various surfactant self-assemblies and a unified perspective on this topic. It provides researchers with a useful guide for the dynamics of the surfactant systems that they wish to investigate.

Principles of Adsorption and Reaction on Solid Surfaces

As with other books in the field, Principles of Adsorption and Reaction on Solid Surfaces describes what occurs when gases come in contact with various solid surfaces. But, unlike all the others, it also explains why. While the theory of surface reactions is still under active development, the approach Dr. Richard Masel takes in this book is to outline general principles derived from thermodynamics and reaction rate theory that can be applied to reactions on surfaces, and to indicate ways in which these principles may be applied. The book also provides a comprehensive treatment of the latest quantitative surface modeling techniques with numerous examples of their use in the fields of chemical engineering, physical chemistry, and materials science. A valuable working resource and an excellent graduate-level text, Principles of Adsorption and Reaction on Solid Surfaces provides readers with:

  • A detailed look at the latest advances in understanding and quantifying reactions on surfaces
  • In-depth reviews of all crucial background material
  • 40 solved examples illustrating how the methods apply to catalysis, physical vapor deposition, chemical vapor deposition, electrochemistry, and more
  • 340 problems and practice exercises
  • Sample computer programs
  • Universal plots of many key quantities
  • Detailed, class-tested derivations to help clarify key results

The recent development of quantitative techniques for modeling surface reactions has led to a number of exciting breakthroughs in our understanding of what happens when gases come in contact with solid surfaces. While many books have appeared describing various experimental modeling techniques and the results obtained through their application, until now, there has been no single-volume reference devoted to the fundamental principles governing the processes observed.

The first book to focus on governing principles rather than experimental techniques or specific results, Principles of Adsorption and Reaction on Solid Surfaces provides students and professionals with a quantitative treatment of the application of principles derived from the fields of thermodynamics and reaction rate theory to the investigation of gas adsorption and reaction on solid surfaces. Writing for a broad-based audience including, among others, chemical engineers, chemists, and materials scientists, Dr. Richard I. Masel deftly balances basic background in areas such as statistical mechanics and kinetics with more advanced applications in specialized areas.

Principles of Adsorption and Reaction on Solid Surfaces was also designed to provide readers an opportunity to quickly familiarize themselves with all of the important quantitative surface modeling techniques now in use. To that end, the author has included all of the key equations involved as well as numerous real-world illustrations and solved examples that help to illustrate how the equations can be applied. He has also provided computer programs along with universal plots that make it easy for readers to apply results to their own problems with little computational effort.

Principles of Adsorption and Reaction on Solid Surfaces is a valuable working resource for chemical engineers, physical chemists, and materials scientists, and an excellent text for graduate students in those disciplines.

Surfactants - In Solution, at Interfaces and in Colloidal Dispersions (Hardcover): Bob Aveyard Surfactants - In Solution, at Interfaces and in Colloidal Dispersions (Hardcover)
Bob Aveyard
R2,302 Discovery Miles 23 020 Ships in 12 - 19 working days

Surfactants... today you have probably eaten some, or rubbed others on your body. Plants, animals (including you) and microorganisms make them, and many everyday products (e.g. detergents, cosmetics, foodstuffs) contain them. Surfactant molecules have one part which is soluble in water and another which is not. This gives surfactant molecules two valuable properties: 1) they adsorb at surfaces (e.g. of an oil droplet in water), and 2) they stick together (aggregate) in water. The aggregates (micelles) are able to dissolve materials not soluble in water alone, and adsorbed surfactant layers, at the surfaces of particles or (say) oil droplets in water, stop the particles or drops sticking together. This is why stable emulsions such as milk do not separate into layers. This book treats the basic physical chemistry and physics underlying the behaviour of surfactant systems. In this book, you will first learn about some background material including hydrophobic hydration, interfacial tension and capillarity (Section I). Discussion of surfactant adsorption at liquid/fluid and solid/liquid interfaces is given in Section II, and includes thermodynamics of adsorption, dynamic and rheological aspects of liquid interfaces and the direct characterisation of surfactant monolayers. In Section III, a description is given of surfactant aggregation to give micelles, lyotropic liquid crystals, microemulsions and Winsor systems. There follows a discussion of surface forces and the way they confer stability on lyophobic colloids and thin liquid films (Section IV). Various dispersions stabilised by adsorbed surfactant or polymer (including solid in liquid dispersions, emulsions and foams) are considered in Section V. The wetting of solids and liquids is explored in Section VI. Like surfactants, small solid particles can adsorb at liquid/fluid interfaces, form monolayers and stabilise emulsions and foams. Such behaviour is covered in Section VII. It is assumed the reader has a knowledge of undergraduate physical chemistry, particularly chemical thermodynamics, and of simple physics. Mathematics (elementary algebra and calculus) is kept at a level consistent with the straightforward derivation of many of the equations presented.

Redouane Borsali, R. Pecora
R5,640 Discovery Miles 56 400 Ships in 10 - 15 working days

This volume is based on lectures given at the NATO-Advanced Study Institute on Structure and Dynamics of Polymer and Colloid Systems held in Les Houches, France from September 14-24, 1999. The meeting arose from a perceived need to bring together scientists studying the polymer and colloid fields. Although these fields are intertwined and share many techniques (e. g. , light, neutron and x-ray scattering), it is remarkable how little the approaches and concepts used by the one field penetrate the other. For instance, the theory of spherical colloids is very highly developed and many of the concepts developed for these systems can be extended to those with non-spherical morphology, such as solutions of rigid rod polymers. In addition, mixtures of polymers and colloids, both in the bulk and at interfaces, are the basis for many industrial products. Methods are now rapidly being developed for understanding the structure and dynamics in polymer/colloid mixtures at the molecular level, but the point of view of the colloid scientist is often rather different from that of the polymer scientist. The NATO-ASI brought together polymer and colloid scientists, including many young researchers, who presented and discussed recent developments in these fields and the possibilities for cross-fertilization This volume contains articles on a wide variety of topics at the research forefront of the polymer and colloid fields by some of the world's foremost experts at a level accessible to graduate students, post-docs and researchers.

R2,979 Discovery Miles 29 790 Ships in 10 - 15 working days

During my professional career, I developed a strong interest in sol-gel technology, and worked on both xerogel and aerogel systems. My fascination with aerogels has driven me to explore their commercial potential, which is currently an important component of my company's business plan. Together with my co-workers, I have also worked on the preparation of controlled PZT and silica xerogels as well as thin film coatings of metals by the sol-gel technology, These experiences convinced me of the tremendous potentials of this technology. A conviction that is shared by many scientists, engineers, and business leaders around the globe. Many sol-gel derived products are already articles of commerce. However, to expand the commercial potential of sol-gel technology, two challenges must be met: (1) the quality of sol-gel derived products must continue to meet or exceed the quality of competing products, (2) the production cost of sol-gel products (specially aerogels) must continued to decline. A key to lowering the costs of sol-gel products is finding inexpensive precursors.

R1,745 Discovery Miles 17 450 Ships in 10 - 15 working days

This book investigates the adsorption dynamics of water, methanol, ethanol, and ammonia vapor on loose and consolidated adsorbent beds, as well as the impact of this aspect on the overall performance of adsorption systems for heat transformation. In particular, it presents the results of kinetic measurements made using the large temperature jump (LTJ) method, the most efficient way to study adsorption dynamics under realistic operating conditions for adsorptive heat transformers. The information provided is especially beneficial for all those working on the development of novel adsorbent materials and advanced adsorbers for heating and cooling applications. Today, technologies and systems based on adsorption heat transformation (AHT) processes offer a fascinating option for meeting the growing worldwide demand for air conditioning and space heating. Nevertheless, considerable efforts must still be made in order to enhance performance so as to effectively compete with commonly used electrical compression and absorption machines. For this purpose, intelligent design for adsorption units should above all focus on finding a convenient choice of adsorbent material by means of a comprehensive analysis that takes into account both thermodynamic and dynamic aspects. While the thermodynamic properties of the AHT cycle have been studied extensively, the dynamic optimization of AHT adsorbers is still an open issue. Several efforts have recently been made in order to analyze AHT dynamics, which greatly influence overall AHT performance.
