  • Advances in Molecular Structure Research

    • 1 Edición
    • Volumen 1
    • Inglés
    Progress in molecular structure research reflects progress in chemistry in many ways. Much of it is thus blended inseparably with the rest of chemistry. It appears to be prudent, however, to review the frontiers of this field from time to time. This may help the structural chemist to delineate the main thrusts of advances in this area of research. What is even more important though, these efforts may assist the rest of the chemists to learn about new possibilities in structural studies, both methodological and interpretation. The aim is to make this a user-oriented series. Structural chemists of excellence will be critically evaluating a field or direction including their own achievements, and charting expected developments.

Have written just such a book, intended both as a textbook and as a reference.The authors begin by providing a brief description of the nature of light, how it affects matter, and the means and methods of measuring it. A major section of the book is devoted to how light influences living systems, including discussions of photosynthesis, bioluminescence, regulatory mechanisms, and visual transduction of light. The last half of the book is devoted to the biomedical aspects of light, including photoimmunology, photoallergic reactions and other forms of light sensitivity, the optical properties of skin, and various ways that light can be used in therapy treatments.Useful to photobiologists as a comprehensive overview, this book should also appeal to biomedical researchers and advanced students of photobiology.

  • Adaption of Simulated Annealing to Chemical Optimization Problems

    • 1 Edición
    • Volumen 15
    • J.H. Kalivas
    • Inglés
    Optimization problems occurring regularly in chemistry, vary from selecting the best wavelength design for optimal spectroscopic concentration predictions to geometry optimization of atomic clusters and protein folding. Numerous optimization tactics have been explored to solve these problems. While most optimizers maintain the ability to locate global optima for simple problems, few are robust against local optima convergence with regard to difficult or large scale optimization problems. Simulated annealing (SA) has shown a great tolerance to local optima convergence and is often called a global optimizer. The optimizaton algorithm has found wide use in numerous areas such as engineering, computer science, communication, image recognition, operation research, physics, and biology. Recently, SA and variations thereof have shown considerable success in solving numerous chemical optimization problems. The main thrust of this book is to demonstrate the use of SA in a wide range of chemical problems.The potentiality of SA, GSA and other modifications of SA to serve specific needs in a variety of chemical disciplines are covered. A detailed discussion on SA and GSA is given in Chapter 1, presenting the theoretical framework from which a computer program can be written by the reader. The remainder of the book describes applications of SA type algorithms to a diverse set of chemical problems. The final chapter contains an algorithm for GSA written in the MatLab programming environment. This program can be easily adapted to any optimization problem and with only slight modifications, can be altered to perform SA. A general flowchart is also given.

  • Retention and Selectivity in Liquid Chromatography

    Prediction, Standardisation and Phase Comparisons
    • 1 Edición
    • Volumen 57
    • R.M. Smith
    • Inglés
    This book brings together a number of studies which examine the ways in which the retention and selectivity of separations in high-performance liquid chromatography are dependent on the chemical structure of the analytes and the properties of the stationary and mobile phases. Although previous authors have described the optimisation of separations by alteration of the mobile phase, little emphasis has previously been reported of the influence of the structure and properties of the analyte.The initial chapters describe methods based on retention index group increments and log P increments for the prediction of the retention of analytes and the ways in which these factors are influenced by mobile phases and intramolecular interactions. The values of a wide range of group increments in different eluents are tabulated.Different scales of retention indices in liquid chromatography are described for the comparison of separations, the identification of analytes and the comparison of stationary phases. Applications of these methods in the pharmaceutical, toxicology, forensic, metabolism, environmental, food and other fields are reviewed. The effects of different mobile phases on the selectivity of the retention indices are reported. A compilation of sources of reported retention index values are given.Methods for the comparison of stationary phases based on the interactions of different analytes are covered, including lipophilic and polar indices, shape selectivity comparisons, their application to novel stationary phases, and chemometric methods for column comparisons.

  • Advances in Organobromine Chemistry II

    • 1 Edición
    • Volumen 7
    • J.-R. Desmurs + 2 más
    • Inglés
    The organic molecules that are used, particularly in the areas of pharmacy and agrochemicals, are becoming more and more complex both in their chemical nature and spacial configuration. A complex molecular structure is inevitably fragile; it cannot be produced under severe conditions (in particular high pressure and temperature). In addition there is a problem of the scale-up of a product from the laboratory to the industrial scale. The control of the reactivity, selectivity, and yield and the use of sufficiently mild industrial conditions are all factors that must be taken into account by industrial chemists. Amongst the tools giving controllable reactivity, selectivity, and relatively mild reaction conditions is bromine. The organic chemistry of bromine sometimes gives surprising selectivities compared to those of chlorine.This volume which is based on Orgabrom '93, brings together the main contributions presented at this event.

  • Quality Assurance for Environmental Analysis

    Method Evaluation within the Measurements and Testing Programme (BCR)
    • 1 Edición
    • Volumen 17
    • E.A. Maier + 2 más
    • Inglés
    Quality assurance (QA) for environmental analysis is a growing feature of the nineties as is illustrated by the number of QA guidelines and systems which are being implemented nowadays. There is, however, often a huge gap between the implementation and respect of QA guidelines and the technical approach undertaken to improve and validate new analytical methods. This is particularly true for complex determinations involving multi-step methodologies such as those used in speciation and organic analyses.Quality assurance may also be considered from the technical point of view, which is the focus of this book. The techniques used in different analytical fields (inorganic, speciation and organic analysis) are critically reviewed (i.e. discussion of advantages and limitations) and existing tools for evaluating their performance are described (e.g. interlaboratory studies, use of certified reference materials). Particular reference is made to the activities of the Measurements and Testing Programme (BCR) of the European Commission towards the improvement of quality control of environmental analysis.The book has been written by experienced practitioners. By its nature, it serves as a practical reference for postgraduate students and environmental chemists who need a wide overview of the techniques used in environmental analysis and existing ways of evaluating the performance of relevant analytical methods. The critical discussions of the methods described, as well as the development of quality assurance aspects, makes it unique.

  • Quantitative Treatments of Solute/Solvent Interactions

    • 1 Edición
    • Volumen 1
    • P. Politzer + 1 más
    • Inglés
    The primary objective of this volume, the first in a new series entitled Theoretical and Computational Chemistry, is to survey some effective approaches to understanding, describing and predicting ways in which solutes and solvents interact and the effects they have upon each other. The treatment of solute/solvent interactions that is presented emphasizes a synergism between theory and experiment. Data obtained experimentally are used as a basis for developing quantitative theoretical models that permit the correlation and interpretation of the data, and also provide a predictive capability. The latter being of course a key motivation for these efforts. Linear solvation energy relationships have been quite successful in this respect and accordingly receive considerable attention. Other effective approaches, including computational ones, are also being pursued, and are discussed in several chapters. This is an area that is continually evolving, and it is hoped that the present volume will convey a sense of its dynamic nature.

  • Carbohydrate Analysis

    High Performance Liquid Chromatography and Capillary Electrophoresis
    • 1 Edición
    • Volumen 58
    • Z. El Rassi
    • Inglés
    Carbohydrates and glycoconjugates play an important role in several life processes. The wide variety of carbohydrate species and their inherent polydispersity and heterogeneity require separation techniques of high resolving power and high selectivity such as high performance liquid chromatography (HPLC) and capillary electrophoresis (HPCE). In the last decade HPLC, and recently HPCE methods have been developed for the high resolution and reproducible quantitation of carbohydrates. Despite the importance of these two column separation technologies in the area of carbohydrates, no previous book describes specialized methods for the separation, purification and detection of carbohydrates and glycoconjugates by HPLC and HPCE.Therefore, the objective of the present book is to provide a comprehensive review of carbohydrate analysis by HPLC and HPCE by covering analytical and preparative separation techniques for all classes of carbohydrates including mono- and disaccharides; linear and cyclic oligosaccharides; branched heterooligosaccharid... (e.g., glycans, plant-derived oligosaccharides); glycoconjugates (e.g., glycolipids, glycoproteins); carbohydrates in food and beverage; compositional carbohydrates of polysaccharides; carbohydrates in biomass degradation; etc.The book will be of interest to a wide audience, including analytical chemists and biochemists, carbohydrate, glycoprotein and glycolipid chemists, molecular biologists, biotechnologists, etc. It will also be a useful reference work for both the experienced analyst and the newcomer as well as for users of HPLC and HPCE, graduates and postdoctoral students.

  • Multidimensional Solid-State NMR and Polymers

    • 1 Edición
    • Klaus Schmidt-Rohr + 1 más
    • Inglés
    NMR spectroscopy is the most valuable and versatile analytical tool in chemistry. While excellent monographs exist on high-resolution NMR in liquids and solids, this is the first book to address multidimensional solid-state NMR. Multidimensional techniques enable researchers to obtain detailed information about the structure, dynamics, orientation, and phase separation of solids, which provides the basis of a better understanding of materials properties on the molecular level.Dramatic progress-much of it pioneered by the authors-has been achieved in this area, especially in synthetic polymers. Solid-state NMR now favorably competes with well-established techniques, such as light, x-ray, or neutron scattering, electron microscopy, and dielectric and mechanical relaxation.The application of multidimensional solid-state NMR inevitably involves use of concepts from different fields of science. This book also provides the first comprehensive treatment of both the new experimental techniques and the theoretical concepts needed in more complex data analysis. The text addresses spectroscopists and polymer scientists by treating the subject on different levels; descriptive, technical, and mathematical approaches are used when appropriate. It presents an overview of new developments with numerous experimental examples and illustrations, which will appeal to readers interested in both the information content as well as the potential of solid-state NMR. The book also contains many previously unpublished details that will be appreciated by those who want to perform the experiments. The techniques described are applicable not only to the study of synthetic polymers but to numerous problems in solid-state physics, chemistry, materials science, and biophysics.

    Catalyst Deactivation 1994 was an expansion of earlier, highly successful symposia. The objective of the symposium was to promote a scientific approach of the phenomenon of catalyst deactivation which will contribute to the development of catalysts which are less subject to structural transformations and more resistant to poisons and coke formation. These aspects are dealt with in 12 plenary lectures, 48 oral presentations and 35 poster papers, which were critically selected from an impressive response from some 30 countries.Both fundamental and applied aspects were covered. The deactivation of catalysts in important industrial processes like fluid bed catalytic cracking hydrotreatment, hydrodesulfurization... catalytic reforming, hydrodenitrogenation... steam reforming, hydrodemetallization... hydrocracking, Fischer-Tropsch synthesis, propane dehydrogenation, phthalic anhydride synthesis received considerable attention. Mechanisms of poisoning, sintering and coking were further investigated and modelled and new experimental techniques for the characterization and the quantification of deactivation were also introduced.

    • Inglés
    This Symposium provided the opportunity to review progress after more than 10 years of research and development in the field of natural gas conversion. Oxidative coupling of methane as a route to higher value fuels or feedstock was a major part of the program. The advances in understanding of reaction mechanisms and catalyst structure were discussed in a Plenary paper and in many of the contributed papers.The homogeneous gas phase chemistry involved in methane oxidation is relevant not only to oxidative coupling but also to synthesis gas and methanol production via partial oxidation. This field is reviewed in a Plenary paper and contributed papers describe developments in catalysts and technology for partial oxidation to synthesis gas and to methanol. An alternative route to synthesis gas from methane currently receiving attention is carbon dioxide reforming. This technology is reviewed in a Plenary paper and recent advances are described in contributed papers. The first detailed account of the Shell SMDS Fischer-Tropsch process for production of transport fuels from natural gas recently commercialised in Malaysia is given in this book. Papers discuss structural aspects of Fischer-Tropsch catalysts, modifications of Fischer-Tropsch catalysts to produce light olefins, and the possibilities of operating a Fischer-Tropsch process off-shore. Methanol as an intermediate in natural gas conversion continues to attract attention, and methanol synthesis and conversion are discussed in contributed papers. The possibilities of finding new uses for methane are treated in a Plenary paper and arguments for using methane as a fuel rather than a feedstock are also presented. Among the new uses of methane considered are the generation of electricity in fuel cells and the use of methane as a reductant for NOx emissions.The papers will be of interest to scientists and engineers working in the field of gas conversion, transportation fuels, primary petrochemicals and catalysis.

    The major theme of this book is analytical approaches to trace metal and speciation analysis in biological specimens. The emphasis is on the reliable determination of a number of toxicologically and environmentally important metals. It is essentially a handbook based on the practical experience of each individual author. The scope ranges from sampling and sample preparation to the application of various modern and well-documented methods, including quality assessment and control and statistical treatment of data. Practical advice on avoiding sample contamination is included.In the first part, the reader is offered an introduction into the basic principles and methods, starting with sampling, sample storage and sample treatment, with the emphasis on sample decomposition. This is followed by a description of the potential of atomic absorption spectrometry, atomic emission spectrometry, voltammetry, neutron activation analysis, isotope dilution analysis, and the possibilities for metal speciation in biological specimens. Quality control and all approaches to achieve reliable data are treated in chapters about interlaboratory and intralaboratory surveys and reference methods, reference materials and statistics and data evaluation.The chapters of the second part provide detailed information on the analysis of thirteen trace metals in the most important biological specimens. The following metals are treated in great detail: Aluminium, arsenic, cadmium, chromium, copper, lead, selenium, manganese, nickel, mercury, thallium, vanadium and zinc.The book will serve as a valuable aid for practical analysis in biomedical laboratories and for researchers involved with trace metal and species analysis in clinical, biochemical and environmental research.

    Flow-through sensors are more suitable than classical probe-type sensors for addressing real (non-academic) problems. The external shape and operation of flow-through (bio)chemical sensors are of great practical significance as they facilitate sample transport and conditioning, as well as calibration and sensor preparation, maintenance and regeneration, all of which result in enhanced analytical features and a wider scope of application. This is a systematic presentation of flow-through chemical and biochemical sensors based on the permanent or transient immobilization of any of the ingredients of a (bio)chemical reaction (i.e. the analyte, reagent, catalyst or product) where detection is integrated with the analytical reaction, a separation process (dialysis, gas diffusion, sorption, etc.) or both.The introductory chapter provides an overview of (bio)chemical sensors and their impact on analytical chemistry. Essential concepts of flow-through (bio)chemical sensors including their definition, classification, the types of flow-cells where the sensing microzone can be accommodated, continuous-flow configurations to which they can be coupled, the measurement modes available and the types of transient signals obtained, among others, are the subject of Chapter 2. The remaining chapters classify the most relevant types of flow-through (bio)chemical sensors according to the processes taking place at the sensing (recognition) microzone, as well as their position in space and time.The book deals critically with most types of flow-through sensors, discussing their possibilities and shortcomings to provide a realistic view of the state-of-the-art in the field. The large numbers of figures, the wealth of literature references and the extensive subject index complement the text.
