This book was released on 2012-12-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is no doubt about the importance of hydration in many areas of every day life, technology, biology, medicine, science etc. During the last years many investigations have been carried out upon problems of hydration and a large amount of experimental and theoretical data has been obtained by the application of different methods. One effi cient possibility to stimulate progress in scientific problems is to come together and discuss existing results and ideas. This was the aim of the 35th Bunsenkolloquium and a subsequent seminar held in Marburg, FRG from April 2 -4, 1987 with respect to the "Interaction of Water in Ionic and Nonionic Hydrates". The meeting was attended by more than one hundred participants from 25 countries. It will be seen from the content of the chapters in this book, which comprises the introductory papers and more or less extended abstracts of research seminars, that it was possible not only to stress the advantages and disadvantages of each method, but also to show how information gained by one method can complement the results of another one in order to increase our overall understanding of hydration pheno mena. The papers are divided into sections concerning the hydration of: ions, nonionic substances, biological and macromolecular substances, surfactants as well as a section containing methods, models and theo ries, which may stimulate investigations on hydrations.

Book excerpt: There is no doubt about the importance of hydration in many areas of technology, biology, medicine, science, etc. During the last years many investigations have been carried out on problems of hydration and a large amount of experimental and theoretical data has been obtained from the application of different methods. The papers presented at the symposium Interactions of Water in Ionic and Nonionic Hydrates (Marburg/FRG, 2.-3.4.1987) are divided into sections concerning the hydration of: ions, nonionic substances, biological and macromolecular substances, and surfactants. There is also a section containing methods, models and theories, which may stimulate investigations on hydrations. The success of the meeting may be due to the very different fields of interest of the participants. Thus this volume is a snapshot of the course of research in the large area of hydration. It is hoped that not only readers who are active in the research of interactions of water but also those who are involved in another scientific field and have the impression that hydration may be of importance for the interpretation of their results, will profit from this book.

Download or read book Handbook of Clay Science written by Faïza Bergaya and published by Elsevier. This book was released on 2011-09-14 with total page 1248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first general texts on clay mineralogy and the practical applications of clay, written by R.E. Grim, were published some 40-50 years ago. Since then, a vast literature has accumulated but this information is scattered and not always accessible. The Handbook of Clay Science aims at assembling the scattered literature on the varied and diverse aspects that make up the discipline of clay science. The topics covered range from the fundamental structures (including textures) and properties of clays and clay minerals, through their environmental, health and industrial applications, to their analysis and characterization by modern instrumental techniques. Also included are the clay-microbe interaction, layered double hydroxides, zeolites, cement hydrates, genesis of clay minerals as well as the history and teaching of clay science. No modern book in the English language is available that is as comprehensive and wide-ranging in coverage as the Handbook of Clay Science. In providing a critical and up-to-date assessment of the accumulated information, this will serve as the first point of entry into the literature for both newcomers and graduate students, while for research scientists, university teachers, industrial chemists, and environmental engineers the book will become a standard reference text. * Presents contributions from 66 authors from 18 different countries who have come together to produce the most comprehensive modern handbook on clay science* Provides up-to-date concepts, properties, and reactivity of clays and clay minerals in a one-stop source of information* Covers classical and new environmental, industrial, and health applications of clays, as well as the instrumental techniques for clay mineral analysis* Combines geology, mineralogy, crystallography with physics, geotechnology, and soil mechanics together with inorganic, organic, physical, and colloid chemistry for a truly multidisciplinary approach

Download or read book Intermolecular Forces written by Pierre L. Huyskens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of intermolecular forces began over one hundred years ago in 1873 with the famous thesis of van der Waals. In recent decades, knowledge of this field has expanded due to intensive research into both its theoretical and the experimental aspects. This is particularly true for the type of very strong cohesive force stressed in 1920 by Latimer and Rodebush: the hydrogen bond, a phenomenon already outlined in 1912 by Moore and Winemill. Hydrogen bonds exert a profound influence on most of the physical and chemical properties of the materials in which they are formed. Not only do they govern viscosity and electrical conductivity, they also intervene in the chemical reaction path which determines the kinetics of chemical processes. The properties of chemical substances depend to a large extent on intermolecular forces. In spite of this fundamental fact, too little attention is given to these properties both in research and in university teaching. For instance, in the field of pharmaceutical research, about 13000 compounds need to be studied in order to find a single new product that can be successfully marketed. The recognition of the need to optimize industrial research efficiency has led to a growing interest in promoting the study of inter molecular forces. Rising salary costs in industry have encou raged an interest in theoretical ideas which will lead to tailor made materials.

Download or read book Organic Reactions in Water written by U. Marcus Lindstrom and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volatile organic solvents are the normal media used in both research scale and industrial scale synthesis of organic chemicals. Their environmental impact is significant, however, and so the development of alternative reaction media has become of great interest. Developments in the use of water as a solvent for organic synthesis have reached the point where it could now be considered a viable solvent for many organic reactions. Organic Reactions in Water demonstrates the underlying principles of using water as a reaction solvent and, by reference to a range of reaction types and systems, it’s effective use in synthetic organic chemistry. Written by an internationally respected team of contributors, and with a strong focus on the practical use of water as a reaction medium, this book illustrates the enormous potential of water for the development of new and unique chemistries and synthetic strategies, while at the same time offering a much reduced environmental impact.

Download or read book Modern NMR Techniques for Synthetic Chemistry written by Julie Fisher and published by CRC Press. This book was released on 2014-10-13 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: A blend of theory and practical advice, Modern NMR Techniques for Synthetic Chemistry illustrates how NMR spectroscopy can be used to determine the abundance, size, shape, and function of organic molecules. It provides you with a description the NMR technique used (more pictorial than mathematical), indicating the most common pulse sequences, some practical information as appropriate, followed by illustrative examples. This format is followed for each chapter so you can skip the more theoretical details if the practical aspects are what interest you. Following a discussion of basic parameters, the book describes the utility of NMR in detecting and quantifying dynamic processes, with particular emphasis on the usefulness of saturation-transfer (STD) techniques. It details pulsed–field gradient approaches to diffusion measurement, diffusion models, and approaches to ‘inorganic’ nuclei detection, important as many synthetic pathways to new organics involve heavier elements. The text concludes with coverage of applications of NMR to the analysis of complex mixtures, natural products, carbohydrates, and nucleic acids—all areas of activity for researchers working at the chemistry-life sciences interface. The book’s unique format provides some theoretical insight into the NMR technique used, indicating the most common pulse sequences. The book draws upon several NMR methods that are resurging or currently hot in the field and indicates the specific pulse sequence used by various spectrometer manufacturers for each technique. It examines the analysis of complex mixtures, a feature not found in most books on this topic.

Donald England's review of water-soluble polymers highlights those areas that show unique solution properties or where there is contention as to the explanation for the behavior. The final review by Kenneth Newman addresses the hydration of surfaces, a topic of profound scientific and technological importance. Post-graduate researchers interested in topical, critical reviews will benefit from this volume.

Download or read book The Properties of Water and their Role in Colloidal and Biological Systems written by Carel Jan van Oss and published by Academic Press. This book was released on 2008-09-16 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book treats the different current as well as unusual and hitherto often unstudied physico-chemical and surface-thermodynamic properties of water that govern all polar interactions occurring in it. These properties include the hyper-hydrophobicity of the water-air interface, the cluster formation of water molecules in the liquid state and the concomitant variability of the ratio of the electron-accepticity to electron-donicity of liquid water as a function of temperature, T. The increase of that ratio with T is the cause of the increase in hydration repulsion (“hydration pressure ) between polar surfaces upon heating, when they are immersed in water. The book also treats the surface properties of apolar and polar molecules, polymers, particles and cells, as well as their mutual interaction energies, when immersed in water, under the influence of the three prevailing non-covalent forces, i.e., Lewis acid-base (AB), Lifshitz-van der Waals (LW) and electrical double layer (EL) interactions. The polar AB interactions, be they attractive or repulsive, typically represent up to 90% of the total interaction energies occurring in water. Thus the addition of AB energies to the LW + EL energies of the classical DLVO theory of energy vs. distance analysis makes this powerful tool (the Extended DLVO theory) applicable to the quantitative study of the stability of particle suspensions in water. The influence of AB forces on the interfacial tension between water and other condensed-phase materials is stressed and serves, inter alia, to explain, measure and calculate the driving force of the hydrophobic attraction between such materials (the “hydrophobic effect ), when immersed in water. These phenomena, which are typical for liquid water, influence all polar interactions that take place in it. All of these are treated from the viewpoint of the properties of liquid water itself, including the properties of advancing freezing fronts and the surface properties of ice at 0o C. Explains and allows the quantitative measurement of hydrophobic attraction and hydrophilic repulsion in water Measures the degree of cluster formation of water molecules Discusses the influence of temperature on the cluster size of water molecules Treats the multitudinous effects of the hyper-hydrophobicity of the water-air interface
