This book offers an explanation of the specific ways that biocatalysis outperforms chemical catalysis by: utilizing ambient temperature and atmospheric pressure to minimize problems of isomerization, racemization, and epimerization; employing microbial cells and enzymes that can be immobilized and reused over many cycles; and overexpressing enzymes for greater economy and efficiency.
Volume three deals specifically with the role of monomers and resins in radiation curing. The nature of the backbone of ologomers leads to the ultimate physical or chemical properties of the UV-cured material. This chapter also covers aspects of the chemistry of these compounds in relation to their end uses.
This thesis presents a novel coarse-grained model of DNA, in which bases are represented as rigid nucleotides. The model is shown to quantitatively reproduce many phenomena, including elastic properties of the double-stranded state, hairpin formation in single strands and hybridization of pairs of strands to form duplexes, the first time such a wide range of properties has been captured by a coarse-grained model. The scope and potential of the model is demonstrated by simulating DNA tweezers, an iconic nanodevice, and a two-footed DNA walker - the first time that coarse-grained modelling has been applied to dynamic DNA nanotechnology.
Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information on it Samuel Johnson, 18 April, 1775* Sterols are among the most studied groups of natural products with interest commencing in the 19th century and running to the present. Investigations have embraced the refinement of separation procedures, the development of new analytical techniques and instrumentation for structure elucidation, the unravelling of biosynthetic mechanisms, the determination of the physiological functions of sterols, and the role they play in health and disease. In the past 20-30 years interest in the medical implications of sterol biochemistry, studies on the sterols of plants, algae and fungi, and the identification of the many unusual sterols from marine organisms have proceeded in parallel and somewhat independently. Although the motiva tion and goals for the various lines of investigation have differed widely the researchers working in each of these areas have contributed a wealth of knowledge to the literature relating to the analysis of sterols and many diverse new sterols have been discovered. We conceived this book as a modest attempt to bring together some of this literature in the hope that it may be helpful to newcomers to sterol research. We had originally intended to produce a 'handbook' outlining in detail the protocols to be followed for sterol extraction, chromatography, NMR analysis, etc. in order to identify the components of a sterol mixture."

describing the synthesis of increasingly important glycosidic
linkage analogs, as well as the oligosaccharides containing
derivatives and analogs of natural sugars are included. While
chemical-synthetic methods constitute the major part of the book,
completing the volume is a section on the rapidly expanding and
important field of enzymatic synthesis, also covering combined
chemical and enzymatic synthesis.
This book presents a detailed examination of the physical properties of proteins and their associations with solvents, ligands, and each other. Incorporating observations from his classic work on the thermodynamics of protein-protein and protein-ligand interactions, the internationally recognized author offers a complete conceptual and quantitative description of proteins and their associations. The book begins with an overview of basic thermodynamic principles and goes on to describe the covalent and noncovalent binding of single and multiple ligands and their effects on protein-protein associations. Discussions of protein-solvent interactions address issues including protein folding, membrane associations, and protein dynamics. Attention is given to the effect of temperature and pressure on protein structure, oligomerization, and ligand binding, as well as to ideas about the basis of biological specificity. Although experimental work is discussed throughout the text, the book is not technique oriented. Its theoretical framework is clear, general and easily understandable, making this an essential textbook for beginning graduate students in biological sciences, as well as a valuable reference for advanced researchers in industry and academia.
Since their first industrial use polymers have gained a tremendous success. The two volumes of "Polymers - Opportunities and Risks" elaborate on both their potentials and on the impact on the environment arising from their production and applications. Volume 11 "Polymers - Opportunities and Risks I: General and Environmental Aspects" is dedicated to the basics of the engineering of polymers - always with a view to possible environmental implications. Topics include: materials, processing, designing, surfaces, the utilization phase, recycling, and depositing. Volume 12 "Polymers - Opportunities and Risks II: Sustainability, Product Design and Processing" highlights raw materials and renewable polymers, sustainability, additives for manufacture and processing, melt modification, biodegradation, adhesive technologies, and solar applications. All contributions were written by leading experts with substantial practical experience in their fields. They are an invaluable source of information not only for scientists, but also for environmental managers and decision makers.
This book describes most recent advances and limitations concerning design of adhesive joints under humid conditions and discusses future trends. It presents new approaches to predict the failure load after exposure to load, temperature and humidity over a long period of time. With the rapid increase in numerical computing power there have been attempts to formalize the different environmental contributions in order to provide a procedure to predict assembly durability, based on an initial identification of diffusion coefficients and mechanical parameters for both the adhesive and the interface. A coupled numerical model for the joint of interest is then constructed and this allows local water content to be defined and resulting changes in adhesive and interface properties to be predicted.
This monograph deals with the interrelationship between chemistry and physics, and especially the role played by quantum chemistry as a theory in between these two disciplines. The author uses structuralist approach to explore the overlap between the two sciences, looking at their theoretical and ontological borrowings as well as their continuity. The starting point of this book is that there is at least a form of unity between chemistry and physics, where the reduction relation is conceived as a special case of this unity. However, matters are never concluded so simply within philosophy of chemistry, as significant problems exist around a number of core chemical ideas. Specifically, one cannot take the obvious success of quantum theories as outright support for a reductive relationship. Instead, in the context of a suitably adapted Nagelian framework for reduction, modern chemistry's relationship to physics is constitutive. The results provided by quantum chemistry, in partic ular, have significant consequences for chemical ontology. This book is ideal for students, scholars and academics from the field of Philosophy of Science, and particularly for those with an interest in Philosophy of Chemistry and Physics.

Carbohydrate Chemistry provides review coverage of all publications relevant to the chemistry of monosaccharides and oligosaccharides in a given year. The amount of research in this field appearing in the organic chemical literature is increasing because of the enhanced importance of the subject, especially in areas of medicinal chemistry and biology. In no part of the field is this more apparent than in the synthesis of oligosaccharides required by scientists working in glycobiology. Clycomedicinal chemistry and its reliance on carbohydrate synthesis is now very well established, for example, by the preparation of specific carbohydrate- based antigens, especially cancer-specific oligosaccharides and glycoconjugates. Coverage of topics such as nucleosides, amino-sugars, alditols and cyclitols also covers much research of relevance to biological and medicinal chemistry. Each volume of the series brings together references to all published work in given areas of the subject and serves as a comprehensive database for the active research chemist Specialist Periodical Reports provide systematic and detailed review coverage in major areas of chemical research. Compiled by teams of leading authorities in the relevant subject areas, the series creates a unique service for the active research chemist, with regular, in-depth accounts of progress in particular fields of chemistry. Subject coverage within different volumes of a given title is similar and publication is on an annual or biennial basis.
The homogeneous catalytic hydrogenation of CO and the carbonylation and homologation of alcohols and their derivatives emerged nearly 40 years ago, in the U.S.A. and Germany. Since that time, the two topics have generally been reviewed separately, with no concern for their common aspects, in terms of both the chemical transformations involved, nor for the catalytic aspects, until Japanese workers, during the National C1 Chemistry Project, which ran from 1980 to 1987, unified both the scientific and technological approaches in the field. The literature from 1940--1980 has been well reviewed, and so the time is now ripe for a thorough, careful review of work accomplished since then. Under the editorial inspiration of Professor Braca, Oxygenates by Homologation or CO Hydrogenation with Metal Complexes presents an authoritative reconsideration and review of research on oxygenate production by CO hydrogenation, and the homologation of alcohols, aldehydes, ethers and esters in the presence of transition metal complexes. The three chapters of the book, each presenting a masterly overview of its topic, are entitled: Monoalcohols, Glycols and their Ethers and Esters by CO Hydrogenation; Alcohols and Derivatives by Homologation with SynGas; and Hydrocarbonylation of Aldehydes and their Derivatives. The chapters are presented in a common format, presenting the performances of the catalytic systems of different metals, followed by a general discussion of the reaction mechanism along the successive reaction steps, from the activation of the substrates up to their chemical modification and the restoration of the catalysts. Attention is also paid to the problems of stability and deactivation of thecatalytic systems and to the difficulties of the industrial development of the reactions. (2nd text) This volume presents an overview of the current status of research into homogeneous phase catalytic carbon monoxide hydrogenation and the carbonylation and homologation of alcohols and their derivatives, with emphasis on the progress which has been made since 1982. The concents are divided into three major chapters. Chapter 1 deals with monoalcohols, glycols and their ethers and esters by carbon monoxide hydrogenation. Chapter 2 discusses alcohols and their derivatives by homologation with syngas. Chapter 3 considers the hydrocarbonylation of aldehydes and their derivatives. The organization of the material in each of these chapters follows a common scheme. The performance of catalytic systems of different metals is presented and then reaction mechanisms are discussed for successive reaction steps, from the activation of substrates to their chemical modifications and the restoration of catalysts. Attention is also paid to problems of stability and deactivation of catalytic systems. The difficulties associated with the industrial development of the various reactions is also considered. For research organic chemists in academia and industry whose work involves catalysis.
