DOWNLOAD EBOOK"Molecular Gels: Materials with Self-Assembled Fibrillar Networks" is a comprehensive treatise on gelators, especially low molecular-mass gelators and the properties of their gels. The structures and modes of formation of the self-assembled fibrillar networks (SAFINs) that immobilize the liquid components of the gels are discussed experimentally and theoretically. The spectroscopic, rheological, and structural features of the different classes of low molecular-mass gelators are also presented. Many examples of the application of the principal analytical techniques for investigation of molecular gels (including SANS, SAXS, WAXS, UV-vis absorption, fluorescence and CD spectroscopies, scanning electron, transmission electron and optical microscopies, and molecular modeling) are presented didactically and in-depth, as are several of the theories of the stages of aggregation of individual low molecular-mass gelator molecules leading to SAFINs. Several actual and potential applications of molecular gels in disparate fields (from silicate replication of nanostructures to art conservation) are described. Special emphasis is placed on perspectives for future developments. This book is an invaluable resource for researchers and practitioners either already researching self-assembly and soft matter or new to the area. Those who will find the book useful include chemists, engineers, spectroscopists, physicists, biologists, theoreticians, and materials scientists.

DOWNLOAD EBOOKExplains the physics and chemistry of adhesion, surface preparation and testsPresents new strategies for formulating superior strong, weak and pressure-sensitive adhesivesIncludes access to unique electronic apps that enable numerical modeling of adhesives This technical bound book explains the basic principles of adhesion and shows how they are used to formulate and improve adhesives. The volume starts by laying out key physical and chemical concepts underlying adhesion and adhesives, including strong and weak bonds plus pressure-sensitive (PSA) across multiple polymer, metal and ceramic adherends. The ideas are expressed in clear and easily understood mathematical formulas that explain surface properties as well as "good" and "bad" adhesion, with the latter covering multiple types of adhesive failure. In this context, the book presents a detailed explanation of methods to predict, test and formulate adhesives and critically analyzes test results and traditionally accepted rules for adhesive formulation. The eBook version includes online access to a unique set of applied computer programs or "apps" that automate a wide range of adhesive formulas and enable readers to input their own data and numerically model adhesion properties in conjunction with, or prior to, chemical compounding and empirical testing. This volume constitutes a lucid and practical introduction to adhesion and adhesives appropriate for specialists at all levels.

DOWNLOAD EBOOKOrganic solvents represent a class of compounds whose utility is central to industrial and academic chemistry. The impact of solvents in everyday products such as paints, surface coatings, adhesives, pharmaceuticals and cleaning products is enormous, and there is therefore much interest in their use. This volume is divided into two parts. Part 1 provides and authoritative review of the science and technology of solvents and related issues. The topics covered are solvency and its measurement, flammability, health and toxicology, environmental issues, legislative information, transport, storage, recovery and disposal, and a review of solvent applications. Part 2 provides reliable, up- to-date data, based on information provided by manufacturers and suppliers and is presented as a database of over 350 solvent products, subdivided by solvent group. The data are also presented in key parameter tables, covering boiling points, melting points, evaporation information, vapor pressure, flash points, solubility parameters, auto ignition temperatures, and names and addresses of manufacturers, with trade names. In recent years there has been increased interest in health and safety, environmental issues and aspects of the legislative control of chemicals, including solvents, and the choice of a given solvent has therefore become more complex. The Directory of Solvents aims to provide in one place a broad spread of physico-chemical data, together with transport, safety, environmental and classification information provided by major European and U.S. suppliers and manufacturers of industrial organic solvents.
