  • Self-diffusion in Electrolyte Solutions

    A Critical Examination of Data Compiled from the Literature
    • 1 Edición
    • Volumen 36
    • R. Mills + 1 más
    • Inglés
    This compilation - the first of its kind - fills a real gap in the field of electrolyte data. Virtually all self-diffusion data in electrolyte solutions as reported in the literature have been examined and the book contains over 400 tables covering diffusion in binary and ternary aqueous solutions, in mixed solvents, and of non-electrolytes in various solvents.An important feature of the compilation is that all data have been critically examined and their accuracy assessed. Other features are an introductory chapter in which the methods of measurement are reviewed; appendices containing tables of the limiting self-diffusion coefficients of ions; and a list of references to data which have been omitted but where information about the diffusing system is given.This is the only complete compilation of self-diffusion data in electrolyte solutions. It will appeal to electrochemists in general, particularly now that recent developments in the theory of transport processes require these data. It will also have a special appeal to electroanalytical chemists in that the ionic self-diffusion coefficient is an important quantity for the interpretation of electrode reactions. In addition, the book will interest geochemists and environmental chemists because the migration of radioactive ions from nuclear waste in certain aqueous media will be governed by the tracer-diffusion coefficient.

    • 1 Edición
    • Martin J. O'Donnell + 1 más
    • Inglés
    Annual Reports in Organic Synthesis—1983 presents an annual review of synthetically useful information that would prove beneficial to nearly all organic chemists, both specialist and nonspecialist in synthesis. It should help relieve some of the information storage burden of the specialist and should aid the nonspecialist who is seeking help with a specific problem to become rapidly aware of recent synthetic advances. In producing this volume the editors abstracted 47 primary chemistry journals, selecting useful synthetic advances. All reactions and methods which are new, synthetically useful, and reasonably general are included. Each entry is comprised primarily of structures accompanied by very few comments. The purpose of this is to aid the reader in rapidly scanning the book. Chapters I-III are organized by reaction type and constitute the major part of the book. Chapter IV deals with methods of synthesizing heterocyclic systems. Chapter V covers the use of new protecting groups. Chapter VI is divided into three main parts and covers those synthetically useful transformations that do not fit easily into the first three chapters. The first part deals only with functional group synthesis. The second part covers ring expansion and contraction, and the third part involves useful multistep sequences.

  • Viscous Flows

    The Practical Use of Theory
    • 1 Edición
    • Howard Brenner
    • Inglés
    Representing a unique approach to the study of fluid flows, Viscous Flows demonstrates the utility of theoretical concepts and solutions for interpreting and predicting fluid flow in practical applications. By critically comparing all relevant classes of theoretical solutions with experimental data and/or general numerical solutions, it focuses on the range of validity of theoretical expressions rather than on their intrinsic character.This book features extensive use of dimensional analysis on both models and variables, and extensive development of theoretically based correlating equations. The range of applicability of most theoretical solutions is shown to be quite limited; however, in combination they are demonstrated to be more reliable than purely empirical expressions, particularly in novel applications.

  • Through France with Berzelius

    Live Scholars and Dead Volcanoes
    • 1 Edición
    • C. G. Bernhard
    • Inglés
    There are 165 years between Jöns Jacob Berzelius' and Carl Gustaf Bernhard's excursions through the Massif Central in France. In spite of their circumstantial differences, the similarities between the two men of letters is striking. While Berzelius is renowned as one of the founders of modern chemistry and mineralogy, the bulk of Bernhard's achievement has been in the field of neurophysiology--yet both men emerge as having remarkably similar approaches to science and nature. It was as Berzelius' successor to the post of Secretary of the Royal Swedish Academy of Sciences that first gave Bernhard cause to study his literary remains. This was to provide the inspiration for Bernhard, with Berzelius as his guide, to visit the volcanic landscape, in which the remains of Roman columns, mediaeval castles and cathedrals recalled civilizations which have come and gone through the centuries following the geological eruptions. The book is extensively illustrated with sketches of the countryside, portraits of those known by Berzelius as well as colour photographs of the landscape taken by Bernhard, while the narrative alternates between excerpts of Berzelius' letters and writings and Bernhard's own modern travelogue. The result is a fascinating textual and pictorial record of one of the most beautiful regions of France, and of two highly influential Swedish scientists, spanning the last two centuries.

  • Graphite Fluorides

    • 1 Edición
    • Volumen 8
    • N. Watanabe + 2 más
    • Inglés
    This volume reviews the preparation, structures, physicochemical properties and applications of graphite fluorides, mainly based on the results obtained by the authors. Their interest in graphite fluorides stemmed from research on the ``anode effect'', in electrolytic production of fluorine gas in KF.2HF melt using carbon electrodes.The formation of a thin graphite fluoride film on carbon anodes made it difficult to continue the electrolysis of KF.2HF at a high current density. To elucidate this phenomenon studies on graphite fluoride were initiated. In the course of these systematic studies, the use of graphite fluoride in high-energy batteries became successful: a new graphite fluoride (C2F)n was found; and another fluorineographite intercalation compound with ionic bonding, CxF, was synthesized. During this research it was established that CxF is closely associated with the ``anode effect''.The book will be of interest to all those involved in the study and research of graphite fluorides, particularly fluorine chemists, electrochemists, and fluorine and battery companies.

  • Organic Chemistry in Action

    The Design of Organic Synthesis
    • 1 Edición
    • Volumen 41
    • F. Serratosa
    • Inglés
    Contrary to all other books in the field of organic synthesis, this volume combines Corey's methodology, which is based on the concept of synthon and retrosynthetic analysis, with Evans' methodology based on the `Lapworth model' of alternating polarities. Using this approach, the formation of carbon-carbon bonds and the manipulation of functional groups are treated together, whereas the stereochemical aspects are considered separately. Emphasis is laid on the importance of rigid structures, whether in the starting materials, the synthetic intermediates or the transition states, as a means of controlling the stereochemistry of the organic compounds.Enclosed with the book is a copy of a miniprogram (CHAOS) for an IBM PC, or fully compatible computers, which is an interactive program, affording the beginner a fast and easy way of learning, exploring and looking for new synthetic schemes of molecules of moderate complexity. As a textbook on organic synthesis, this volume will be of immense value at university level.

  • Pharmaceutical and Biomedical Applications of Liquid Chromatography

    • 1 Edición
    • Volumen 1
    • W.J. Lough + 2 más
    • Inglés
    This volume reflects the changes that have taken place in the pharmaceutical industry over the last ten years, most notably the increased importance attached to the question of chirality, the growing influence of biotechnology and the need for more rigorous documentation and validation of analytical methods and procedures.The first part of this book deals with the application of new technology to pharmaceutical and biomedical analysis, reflecting the present needs for increased speed, sensitivity and selectivity in the analysis of drugs. The second chapter provides an overview of capillary electophoresis, which represents one of the most inportant analytical developments to impact directly on pharmaceutical development in recent years. Although not a chromatographic technique, capillary electrophoresis was considered too important to be ignored.Over the last 25 years, liquid chromatography has grown into a mature analytical technique and many of the fundamental issues concerned with retention and separation are well defined. The practitioners of modern liquid chromatography spend as much time in the development of techniques for sampling handling and automation as they do in the development of the separation. Therefore, Part Two of this book describes some of the recent advances in the areas of sample handling and the isolation of compounds from biological samples, including solid phase extraction, restricted access media for direct injection, coupled column technology and microdialysis. Similarily, Part Three contains two chapters concerned with liquid chromatographic methods for the isolation of drug substances, peptides and proteins from other complex media.The pharmaceutical industry and the process of drug development are highly regulated and the increasing importance that the regulatory authorities attach to validation has had a significant impact on the analytical techniques used for the analysis of drugs. Although this has increased the workload of analysts in the pharmaceutical industry, it has also improved the quality of analytical methods used in the support of investigational and new drug applications as well as the quality of methods published more recently in the literature. Consequently, Part Four of this volume describes approaches to the optimization and validation of liquid chromatography methods for the analysis of drugs in the bulk form, in pharmaceutical formulations and biological fluids.
