Nuclear magnetic resonance spectroscopy, which has evolved only within the last 20 years, has become one of the very important tools in chemistry and physics. The literature on its theory and application has grown immensely and a comprehensive and adequate treatment of all branches by one author, or even by several, becomes increasingly difficult. This series is planned to present articles written by experts working in various fields of nuclear magnetic resonance spectroscopy, and will contain review articles as well as progress reports and original work. Its main aim, however, is to fill a gap, existing in literature, by publishing articles written by specialists, which take the reader from the introductory stage to the latest development in the field. The editors are grateful to the authors for the time and effort spent in writing the articles, and for their invaluable cooperation. The papers presented here are condensed versions of the main contributions to the 7th Colloquium on Nuclear Magnetic Resonance Spectroscopy, which was made possible by the generous support of the Freunde der Aachener Hoch schule (FAHO). The RWTH is indebted to the FAHO and to all the participants who contributed to the success of the Colloquium.

This sequel to A Prehistory of Polymer Science begins with the Faraday Discussion of 1935 on Polymerization. Patterson then examines the remarkable rise and establishment of polymer science after 1935 from the perspective of the emergence of strong intellectual leaders. While enough biographical detail is presented to gain an appreciation for the role played by each leader, the emphasis of this volume is on the key concepts associated with each individual and how the community embraced these leaders.

The aim of this 1981 book, designed for senior undergraduates, postgradutes and professionals, is to draw together in one unified presentation a number of the phenomena associated with polymer surfaces. The author begins by describing the theory of surface tension in terms of intermolecular forces and then goes on to consider the practical problem of the factors involved when a liquid wets a polymeric surface and forms a bond to it. An account of polymeric adhesives and their different spheres of application follows, and an examination of the mechanism of failure of adhesive joints leads to a discussion of joint design for optimum strength and environmental resistance. A chapter on friction is closely related to that on adhesion, and the final chapter is devoted to specific frictional mechanisms associated with high hysteresis polymers as well as an introductory discussion of wear.

Polymers are substances containing a large number of structural units joined by the same type of linkage. These substances often form into a chain-like structure. Starch, cellulose, and rubber all possess polymeric properties. Today, the polymer industry has grown to be larger than the aluminium, copper and steel industries combined. Polymers already have a range of applications that far exceeds that of any other class of material available to man. Current applications extend from adhesives, coatings, foams, and packaging materials to textile and industrial fibres, elastomers, and structural plastics. Polymers are also used for most composites, electronic devices, biomedical devices, optical devices, and precursors for many newly developed high-tech ceramics. This book presents leading-edge research in this rapidly-changing and evolving field.

International Series of Monographs on Pure and Applied Biology: The Plant Cell Wall, Volume 2 is a four-chapter text that covers the botanical aspects of cell wall. This book specifically discusses the cell types and cell walls in vascular plants, as well as the classification and constitution of cell wall. This book deals first with the fractionation, biosynthesis, components, formation regulation, and breakdown of cell wall. These topics are followed by discussions on cell wall polysaccharides, lignin structures, cell wall changes during cell growth, and the analysis of the wall-lysing enzymes. Other chapters examine the types and chemical components of cell wall carbohydrates and the surface processes in lignin polymer formations. A study of the phylogenetic aspects of lignins and lignin synthesis is presented. A chapter is devoted to the classification and features of plant species. The remaining chapter focuses on the non-vascular plants, protista, and metazoa. The book can provide useful information to scientists, botanists, students, and researchers.

This collection of texts written by well-recognised specialists was constituted having in view these important directions of actual research. Sustainable economical growth requires safe resources of raw materials for the industrial production. Today's most frequently used industrial raw material, petroleum, is neither sustainable, because limited, nor environmentally friendly. While the economy of energy can be based on various alter-native raw materials, such as wind, sun, water, biomass, as well as nuclear fission and fusion, the economy of substances is fundamentally depending on biomass, in particular biomass of plants. In the last decades because of the crude oil and other natural resources crisis, a new alternative has been proposed consisting in utilisation of renewable natural resources as feedstock and fuel, among which the biomass is the most promising.
