    • Inglés
    The objective in initiating this series in 1980 was to provide an in-depth review of advances made in the understanding key aspects of surface chemistry and physics through the application of new techniques to the study of well-defined surfaces. Since then the field of surface science has greatly matured, and further important techniques, particularly scanning probe microscopies, have been successfully assimilated into the applications armoury of the surface scientist.The present volume is a series of timely reviews by many of the current experts in the field of phase transitions and adsorbate-induced surface restructuring. No aspect of the science of solid surfaces can be fully understood without accounting for the structural diversity of surfaces, now revealed in atomic detail by techniques based on diffraction and scanning probe microscopies. For example, it is now clear to those working in heterogeneous catalysis that adsorbate-induced restructuring of surfaces can play a critical role in phenomena such as bistability, kinetic oscillations, and promotion and poisoning. Structural transitions at surfaces can also play a key role in determining the electronic properties of surfaces, reviewed in volume 5.

  • Multidimensional Pharmacochemistry

    Design of Safer Drugs
    • 1 Edición
    • Peter Mager
    • Inglés
    Multidimensional Pharmacochemistry: Design of Safer Drugs deals with techniques based on the theory of simultaneous statistical inference and the qualitative rules that can be applied in solving problems of high toxicity. This book points out that the multidimensional view of data analysis can be applied to solve problems in medicinal chemistry. Investigators use different approaches; a certain procedure can prove to be the most beneficial for a specific drug design. This text presents the theoretical assumptions that mathematicians make to derive the basis for their multivariate techniques. This book also describes, in nonmathematical terms, a set of methods that are valuable, as well as explain the different designs by using numerical examples. According to E.J. Ariens, drug action involves the pharmaceutical, pharmacokinetic-toxo... and pharmacodynamics-tox... phases. The multivariate structure-activity analysis (MASCA) Model of Pharmacochemistry is a highly unified multivariate approach to drug design. To develop a multidimensionally oriented pharmacology, the book notes that the investigator can use the "dynamic structure-activity analysis." This entails the experimentalist and chemist using quantitative approaches and intuitive elements from a small number of compounds toward larger groups, with successive changes being inputted in the desired biological activity. This book is strongly recommended for toxicologists, pharmacologists, applied mathematicians, medicinal and agricultural chemists.

    • Inglés
    Excited State Lifetime Measurements attempts to assist in clarifying and unifying the many characteristics and definitions of excited state lifetime measurements. The contents of this book are derived from a series of lectures presented to a research group in the University of New Mexico in 1967. The relevance as well as the methods and measurements of data treatment of excited state lifetimes are featured in this book. The first three chapters provide a brief discussion on concepts and applications of excited state lifetime measurements. Experimental methods and systems are also introduced in these chapters. Chapter 4 delves into more complex systems (serial decay kinetics and resonance energy transfer) while Chapter 5 focuses on the method of least squares fitting, its uses, and misuses. Chapters 6 to 8 mainly discuss the convolution integral and its different applications while Chapter 9 gives a more detailed presentation of instrumentation. The last two chapters discuss special errors and approaches to new methodologies regarding the study of the excited state lifetime measurements. The book will be useful to students and scientists including analytical chemists, photochemists, photobiologists, spectroscopists, and physicists.

    • Inglés
    Trace Analysis by Mass Spectrometry deals with trace analysis of solids and liquids by mass spectrometric techniques. Topics include the physics and techniques of electrical discharge ion sources, transmission of ions through double focusing mass spectrometers, and detection and measurement of ions by ion-sensitive plates. The ion sources used are principally electrical discharge type sources. This book is comprised of 14 chapters. The first several chapters focus on the basic physics of electrical discharge ion sources, double focusing mass spectrometry, and the measurement of arrays of mass resolved ion beams by electrical detection methods and with ion sensitive emulsions. The discussion then shifts to the problem of obtaining the chemical composition of the recorded mass resolved ion sample and relating this composition to that of the original sample. The chapters that follow describe specific techniques for analyzing special samples such as insulators, powders, microsamples, biological materials, reactive and low melting point substances, radioactive materials, and gases in solids. The remaining chapters include the use of laser ion sources in the analysis of solids and the analysis of surfaces particularly with sputter ion sources.

  • Stereochemistry of Organometallic and Inorganic Compounds

    • Inglés
    The authors of this fourth volume in the series have reviewed the making and breaking of chemical bonds in a sophisticated manner. In particular, new pressures brought about by environmental concerns, larger demands for the medical and pharmaceutical sectors and economics of the market place are forcing us into demanding greater stereochemical control and better product yields for chemical reactions capable of producing useful products. The chapters are written by leading experts in this area and give excellent overviews of the strengths and weaknesses of the various methodologies.In Chapter 1 newer discoveries in such tried and true methods of C-C bond formation as alkylations and aldol reactions of metal enolates are reviewed. The author of Chapter 2 discusses the ability of ab-initio methods to justify the results of empirical observations in the field of transition metal derivatives of small molecules such as N2, CO2 and similar small molecules. Having established the strengths and weaknesses of the various approaches to such theoretical calculations, a more interesting approach to these methods is pursued, namely, their ability to predict, in those areas in which they are particularly strong and reliable, chemical and stereochemical events and/or results in advance of experiments, later carried out in the laboratory. Finally, Chapter 3 reviews the stereochemical results of electron transfer reactions in mononuclear copper compounds.
