  • Recent Developments and Applications of Modern Density Functional Theory

    • 1 Edición
    • Volumen 4
    • Jorge M. Seminario
    • Inglés
    The present status of Density Functional Theory (DFT), which has evolved as the main technique for the study of matter at the atomistic level, is described in this volume. Knowing the behavior of atoms and molecules provides a sure avenue for the design of new materials with specific features and properties in many areas of science and technology. A technique based on purely first principles allowing large savings in time and money greatly benefits the specialist or designer of new materials.The range of areas where DFT is applied has expanded and continues to do so. Any area where a molecular system is the center of attention can be studied using DFT.The scope of the 22 chapters in this book amply testifies to this.

  • Hypervalent Iodine in Organic Synthesis

    • 1 Edición
    • A. Varvoglis
    • Inglés
    This book describes the fascinating chemistry of the many kinds of organic compounds of hypervalent iodine. Each chapter deals with a particular iodine compound or families of compounds which have been used as reagents in a plethora of useful transformations. These include assorted oxidation, such as with the precious Dess-Martin reagent as well as with a wide range of further reactions. Prominent features of hypervalent iodine reagents derived from iodobenzene are: ready availability, operational simplicity, mild reaction conditions, and high efficiency. They are environmentally safe and can be recycled. New species may be easily prepared by introducing substituents in the benzene ring or changing the ligand attached to iodine. Their combination with other reagents broadens considerably their synthetic potential. Today, no synthetic chemist can afford to ignore the valuable hypervalentiodine reagents.

  • Advanced Thermodynamics for Engineers

    • 1 Edición
    • D. Winterbone + 1 más
    • Inglés
    Although the basic theories of thermodynamics are adequately covered by a number of existing texts, there is little literature that addresses more advanced topics. In this comprehensive work the author redresses this balance, drawing on his twenty-five years of experience of teaching thermodynamics at undergraduate and postgraduate level, to produce a definitive text to cover thoroughly, advanced syllabuses.The book introduces the basic concepts which apply over the whole range of new technologies, considering: a new approach to cycles, enabling their irreversibility to be taken into account; a detailed study of combustion to show how the chemical energy in a fuel is converted into thermal energy and emissions; an analysis of fuel cells to give an understanding of the direct conversion of chemical energy to electrical power; a detailed study of property relationships to enable more sophisticated analyses to be made of both high and low temperature plant and irreversible thermodynamics, whose principles might hold a key to new ways of efficiently covering energy to power (e.g. solar energy, fuel cells). Worked examples are included in most of the chapters, followed by exercises with solutions. By developing thermodynamics from an explicitly equilibrium perspective, showing how all systems attempt to reach a state of equilibrium, and the effects of these systems when they cannot, the result is an unparalleled insight into the more advanced considerations when converting any form of energy into power, that will prove invaluable to students and professional engineers of all disciplines.

  • Modern Aspects of Diffusion-Controlled Reactions

    Cooperative Phenomena in Bimolecular Processes
    • 1 Edición
    • Volumen 34
    • E. Kotomin + 1 más
    • Inglés
    This monograph deals with the effects of reactant spatial correlations arising in the course of basic bimolecular reactions describing defect recombination, energy transfer and exciton annihilation in condensed matter. These effects lead to the kinetics considered abnormal from the standard chemical kinetics point of view. Numerous bimolecular reaction regimes and conditions are analysed in detail. Special attention is paid to the development and numerous applications of a novel, many-point density (MPD) formalism, which is based on Kirkwood's superposition approximation used for decoupling three-particle correlation functions.The book demonstrates that incorporation of the reaction-induced spatial correlations of similar reactants (e.g., vacancy-vacancy) leads to the development of an essentially non-Poisson spectrum of reactant density fluctuations. This can completely change the kinetics at longer times since it no longer obeys the law of mass action. The language of the correlation lengths and critical exponents similar to physics of critical phenomena is used instead. A relation between MPD theory and synergistics is discussed. The validity of the theorem giving a critical complexity for the two-step reactions exhibiting self-organization phenomena is questioned. Theoretical results are illustrated by numerous experimental data.

  • Advances in Organometallic Chemistry

    • 1 Edición
    • Volumen 40
    • Inglés
    This widely acclaimed serial contains authoritative reviews that address all aspects of organometallic chemistry, a field which has expanded enormously since the publication of Volume 1 in 1964. Almost all branches of chemistry and material science now interface with organometallic chemistry - the study of compounds containing carbon-metal bonds. Organometallic compounds range from species which are so reactive that they only have a transient existence at ambient temperatures to species which are thermally very stable. Organometallics are used extensively in the synthesis of useful compounds on both large and small scales. Industrial processes involving plastics, polymers, electronic materials, and pharmaceuticals all depend on advancesments in organometallic chemistry. In basic research, Organometallics have contributed inter alia to metal cluster chemistry, surface chemistry, the stablilization of highly reactive species by metal coordination, chiral synthesis, the formulation of multiple bonds between carbon and the other elements and between the elements themselves. Advances in Organometallic Chemistry is an essential reference work for the academic and industrial chemist and will provide up-to-date material at the cutting edge of chemistry research.

  • Synthetic and Natural Phenols

    • 1 Edición
    • Volumen 52
    • J.H.P. Tyman
    • Inglés
    The chemistry of phenols tends to be ignored in organic chemical textbooks and to be lost amongst the many classes of functional derivatives. This volume is not intended to provide a textbook approach but rather to give an account of developments in phenol chemistry in the last two decades.Features of this book:• Numerous phenolic systems have been covered in detail, e.g. phenolic propanoids.• The emphasis throughout has been on synthesis, on what can be achieved by the use of phenolic intermediates and in the construction of phenolic end products.• Many chapters enable the reader to refer to the original literature wherever possible.• Various chapters provide a fund of tutorial material and problems for undergraduate studies and further, which will encourage perusal of the literature. Some 2000 references to applied and academic papers are given.Phenols are ubiquitous substances and now it is more widely accepted that there are pros and cons connected with their usage. The pros for compounds are well-known and are illustrated by perennial panaceas such as aspirin, paracetamol, codeine, etc. The cons are less obvious because they are also materials deeply entrenched in our standard of living and in most cases inherent hazards have only recently come to light. The book will be of interest to postgraduate students in academic and industrial work.

  • Signal Treatment and Signal Analysis in NMR

    • 1 Edición
    • Volumen 18
    • D.N. Rutledge
    • Inglés
    Signal analysis and signal treatment are integral parts of all types of Nuclear Magnetic Resonance. In the last ten years, much has been achieved in the development of dimensional spectra. At the same time new NMR techniques such as NMR Imaging and multidimensional spectroscopy have appeared, requiring entirely new methods of signal analysis. Up until now, most NMR texts and reference books limited their presentation of signal processing to a short introduction to the principles of the Fourier Transform, signal convolution, apodisation and noise reduction. To understand the mathematics of the newer signal processing techniques, it was necessary to go back to the primary references in NMR, chemometrics and mathematics journals.The objective of this book is to fill this void by presenting, in a single volume, both the theory and applications of most of these new techniques to Time-Domain, Frequency-Domain and Space-Domain NMR signals. Details are provided on many of the algorithms used and a companion CD-ROM is also included which contains some of the computer programs, either as source code or in executable form. Although it is aimed primarily at NMR users in the medical, industrial and academic fields, it should also interest chemometricians and programmers working with other techniques.

  • Interfacial Tensiometry

    • 1 Edición
    • Volumen 3
    • A.I. Rusanov + 1 más
    • Inglés
    This is the first monograph devoted to interfacial tensiometry and is therefore the definitive source of information on measuring surface tension. More than 40 methods for measuring surface tension both at the liquid-fluid and solid-fluid boundaries are described including methods using computational techniques, tele- and video-apparatus, and laser techniques. A central place in the book has been given to methods based on the investigation of properties of liquid and gaseous menisci both in the presence or absence of a gravitational field and a rotational one. Their description is preceded by a chapter on the theory of menisci including the derivation of various forms of the Laplace formula. The application of the methods for studying the equilibrium and dynamic surface tension has been considered. Dynamic methods used for very small surface life-times are described and a separate chapter is devoted to the theory of surface tension which will ensure a better understanding of the material. A systematic analysis of the material embracing all kinds of interfaces including solid surfaces, the history of each method, its theoretical foundation, characterization of measuring procedures and setups, a large number of numeric tables and plots and representative illustrations make the book encyclopedic in character.

  • Development and Validation of Analytical Methods

    • 1 Edición
    • Volumen 3
    • Christopher M. Riley + 1 más
    • Inglés
    The need to validate an analytical or bioanalytical method is encountered by analysts in the pharmaceutical industry on an almost daily basis, because adequately validated methods are a necessity for approvable regulatory filings. What constitutes a validated method, however, is subject to analyst interpretation because there is no universally accepted industry practice for assay validation. This book is intended to serve as a guide to the analyst in terms of the issues and parameters that must be considered in the development and validation of analytical methods. In addition to the critical issues surrounding method validation, this book also deals with other related factors such as method development, data acquisition, automation, cleaning validation and regulatory considerations. The book is divided into three parts. Part One, comprising two chapters, looks at some of the basic concepts of method validation. Chapter 1 discusses the general concept of validation and its role in the process of transferring methods from laboratory to laboratory. Chapter 2 looks at some of the critical parameters included in a validation program and the various statistical treatments given to these parameters.Part Two (Chapters 3, 4 and 5) of the book focuses on the regulatory perspective of analytical validation. Chapter 3 discusses in some detail how validation is treated by various regulatory agencies around the world, including the United States, Canada, the European Community, Australia and Japan. This chapter also discusses the International Conference on Harmonization (ICH) treatment of assay validation. Chapters 4 and 5 cover the issues and various perspectives of the recent United States vs. Barr Laboratories Inc. case involving the retesting of samples. Part Three (Chapters 6 - 12) covers the development and validation of various analytical components of the pharmaceutical product development process. This part of the book contains specific chapters dedicated to bulk drug substances and finished products, dissolution studies, robotics and automated workstations, biotechnology products, biological samples, analytical methods for cleaning procedures and computer systems and computer-aided validation. Each chapter goes into some detail describing the critical development and related validation considerations for each topic.This book is not intended to be a practical description of the analytical validation process, but more of a guide to the critical parameters and considerations that must be attended to in a pharmaceutical development program. Despite the existence of numerous guidelines including the recent attempts by the ICH to be implemented in 1998, the practical part of assay validation will always remain, to a certain extent, a matter of the personal preference of the analyst or company. Nevertheless, this book brings together the perspectives of several experts having extensive experience in different capacities in the pharmaceutical industry in an attempt to bring some consistency to analytical method development and validation.

  • Indoles

    • 1 Edición
    • Richard J. Sundberg
    • Inglés
    Indoles continue to be of great interest to the pharmaceutical industry and at the current time several thousand specific new derivatives are reported annually. Research has been driven by the wide range of indole derivatives which occur in nature and through the biological activity of many indole derivatives, of both natural and synthetic origin.This book provides a systematic guide to the most useful and important reactions in the field for both synthesis and synthetic modification of the indole ring. While including the most recently developed and promising methods, it also updates informationavailable on classical methods to give the reader an up-to-date and comprehensive view of the subject. The methods are illustrated by procedures drawn from the literature and by tables including examples chosen to indicate both the scope of applicabilityand variations in methodology. The organization of the book is based on the retrosynthetic concept of identifying the bond(s) formed in the reaction, which in turn identifies potential starting materials.

    Based on a concrete set of working MATLAB programs, the book begins with a short program of snippets describing basic principles and proceeds to a complete application program filling a central analytical need: obtaining pure spectra from the observed overlapping spectra, with standard deviations for thesolutions obtained.The strength of the book is the open nature of the programs. All programs can be read, tested and modified by the user. The mathematical principles needed for the proper treatment of experimental data are thoroughly described. The first part of the book describes how data iscollected, converted and prepared for the actual deconvolution. Practical working algorithms such as the Savitzky-Golay smoothing method are emphasized. The reader can see how searches in spectral libraries can be greatly speeded up by proper formulation of the calculation. Basic signal processing is described by illustrative examples.The main part of the book describes the deconvolution of overlapping chromatographic peaks. Principle component analysis is described and used as a useful tool. The main emphasis is a discussion of a deconvolution method, OSCAR (Optimization by Stepwise Constraining of Alternating Regression), developed by the authors. The results can be validated as OSCAR calculates confidence intervals for the spectra and elution curves.For users who do not want to enter the programs by hand a separate CD-ROM is available.

    • Inglés
    In recent years C-glycoside chemistry has been one of the main topics in carbohydrate chemistry, not only because of the synthetic challenges posed, but also because C-glycosides have the potential to serve as carbohydrate analogues resistant to metabolic processes. Consequently, this class of compounds is currently receiving much interest as a potential source of therapeutic agents for clinical use. This book provides a broad coverage of the various synthetic methods available for the preparation of C-glycosides, and illustrates the interesting breadth of connections between carbohydrate chemistry and modern general synthetic organic chemistry by including topics such as transition-metal catalysis, radical chemistry, cycloaddition and rearrangement processes. In addition, in the final chapter of the book, the syntheses of C-di and trisaccharides reported through 1994 are reviewed. This well organised account of the synthetic chemistry in this field will prove to be very valuable to a wide range of researchers and advanced students, both as an introduction to the topic and for reference.

    The series Advances in Dendritic Macromolecules aims to cover the synthetic, as well as chemical, aspects of this expanding field: the chemistry to and supramolecular chemistry of dendritic or cascade supermolecular compounds. In Chapter 1 of this volume, Hawker and Wooley delineate the convergent growth approach to dendrimers, then relate their three-dimensional architectures to different block polymers. In Chapter 2, Moors and Vögtle describe Professor Vögtle's initial cascade molecules via the repetitive strategy, then expand his original concepts of its application by others, and lastly delineate the synthesis of a new series of tosylamide cascades. They also demonstrate the utility of his original Michael addition/reduction procedure by its application to differ cores. Chapter 3, composed by Professor Engel, describes ionic dendrimers which incorporated an internal transition metal center as well as his work based on ammonium and phosphonium centers. In Chapter 4, Mathias and Carothers review recent studies on silicon-based dendrimers and hyperbranched polymers. Chapter 5, by Kim, describes the preparation and utility of hyperbranched aromatic polymers. Lastly in Chapter 6, Escamilla reviews the historical as well as recent examples of ionic and nonionic bolaamphiphiles.
