Surface chemistry and adsorption Books

Book SynopsisPart of the new Ladybird Expert series, Bubbles is a clear, surprising and entertaining introduction to the science of bubbles. Bubbles are beautiful, ephemeral, fun, fragile, jolly and slightly unpredictable. We''re all familiar with them, but we don''t often ask what they actually are. The great scientists of the Western world - Robert Hooke, Isaac Newton, Lord Rayleigh and more - studied bubbles seriously. They recognised that they had a lot to say about the nature of the physical world, and they poked, prodded and listened to find out what it was. In the years since, we''ve learned that this bulbous arrangement of liquid and gas does things that neither the gas or the liquid could do by itself. Written by the celebrated physicist and oceanographer Helen Czerski, Bubbles explores how everything from the way drinks taste to the Earth''s temperature are influenced by bubbles. This book has a message: never underestimate a bubble!Written by the leading lights and most outstanding communicators in their fields, the Ladybird Expert books provide clear, accessible and authoritative introductions to subjects drawn from science, history and culture.For an adult readership, the Ladybird Expert series is produced in the same iconic small hardback format pioneered by the original Ladybirds. Each beautifully illustrated book features the first new illustrations produced in the original Ladybird style for nearly forty years.Trade ReviewThe artwork is gloriously retro, echoing the original Ladybird house style but containing completely up to date information. * Shiny New Books *

Book SynopsisAn introductory review of the various theoretical and practical aspects of adsorption by powders and porous solids with particular reference to materials of technological importance. It includes chapters dealing with experimental methodology and the interpretation of adsorption data obtained with porous oxides, carbons and zeolites.Trade Review"An introductory chapter summarizes relevance, history, and terminology of adsorption, including chemisorption vs. physisorption, and discusses energetics, molecular modeling, and diffusion. The following chapters treat thermodynamics at a gas/solid and solid/liquid interfaces, measurement and monitoring technique, isotherm theory and interpretation, mathematical modeling of adsorption processes, and use of adsorption to measure surface area and porosity of materials." --ProtoView.com, January 2014 Review of first edition: "A long-awaited but worthy successor to the book considered by many to be the bible of porous materials characterization: ‘Gregg & Sing’ (2nd Edition, 1982). This collaboration between the Rouquerols and Ken Sing has created a detailed handbook covering not only important theoretical aspects, but copious experimental and application information too. Adsorption calorimetry gets more attention than before (not surprising given the Rouquerols' affiliation), as do ‘new’ materials such as MCM's and ‘new’ calculation models like DFT (Density Functional Theory) and Monte Carlo simulation. Importantly, there is a great deal of coverage given to adsorptives other than nitrogen (the most common but not necessarily the most appropriate in all cases). Hundreds of references are given for follow-up reading in areas of special interest. Anyone seeking a reliable, broad, yet highly informative coverage of adsorption methodology for porous materials characterization should invest in this title." --Worthy Successor by "thomasetc" (USA), June 2000, Amazon.comTable of ContentsPreface List of main symbols 1.

Book SynopsisPhotoalignment possesses significant advantages in comparison with the usual rubbing' treatment of the substrates of liquid crystal display (LCD) cells as it is a non-contact method with a high resolution. A new technique recently pioneered by the authors of this book, namely the photo-induced diffusion reorientation of azodyes, does not involve any photochemical or structural transformations of the molecules. This results in photoaligning films which are robust and possess good aligning properties making them particularly suitable for the new generation of liquid crystal devices. Photoalignment of Liquid Crystalline Materials covers state-of-the-art techniques and key applications, as well as the authors' own diffusion model for photoalignment. The book aims to stimulate new research and development in the field of liquid crystalline photoalignment and in so doing, enable the technology to be used in large scale LCD production.

Book SynopsisCovers the latest developments in modeling elastohydrodynamic lubrication (EHL) problems using the finite element method (FEM) This comprehensive guide introduces readers to a powerful technology being used today in the modeling of elastohydrodynamic lubrication (EHL) problems. It provides a general framework based on the finite element method (FEM) for dealing with multi-physical problems of complex nature (such as the EHL problem) and is accompanied by a website hosting a user-friendly FEM software for the treatment of EHL problems, based on the methodology described in the book. Finite Element Modeling of Elastohydrodynamic Lubrication Problems begins with an introduction to both the EHL and FEM fields. It then covers Standard FEM modeling of EHL problems, before going over more advanced techniques that employ model order reduction to allow significant savings in computational overhead. Finally, the book looks at applications that show how the developed modeling framework could be uTable of ContentsPreface xiii Nomenclature xvii About the CompanionWebsite xxv Part I Introduction 1 1

Book SynopsisVolume 3 of Annual Surfactants Review focuses on the diversity of surfactants, both in terms of chemical structure and physico-chemical / surface active properties. These properties may be predictable for simple molecules, but for most commercial surfactants (which may be regarded as multi-component blends) this is not so easy. In the first chapter of this volume, detailed consideration is given to surfactant applications in the context of structure-performance relationships. The end uses of surface active agents are classified by industrial sector and the surfactant properties required for each application are presented in detail. The result is a unique guide to the influence of chemical structure on performance in end use. Many applications of surfactants feature formulations which incorporate polymeric materials. The topic of surfactant-polymer interactions is receiving considerable attention at present and so a chapter has been included on this area. In an attempt to illustrate the diversity of surfactant uses and focus on some of the latest developments in application technology, five areas of application are presented: natural surfactants for drug delivery systems, surfactants used in the construction industry, preparation and end uses of inverse emulsions (for example, as flocculants), the use of surfactants in plastics flotation (part of the plastics recycling process) and the role of surfactants in 'dynamic wetting'.Trade Review"A fine book with excellent information presented in a pleasant form. I recommend it for purchase as both a 'technology update' book and as a 'reference' book" - Journal of Surfactants and DetergentsTable of ContentsSurfactant applications in the context of structure-performance relationships; Surfactants in inverse (water-in-oil) emulsion polymers of acrylamide; Inter-actions between polymers and surfactants; Use of surfactants in plastic flotation; Surface-active agents in the construction industry; The role of surfactants in dynamic wetting; Interfacial properties of natural surfactants and their application in drug delivery systems; References; Index.
