In the course of our individual research programs, we have had occasion to utilize hetero Diels-Alder reactions as pivotal steps in natural product total syntheses. It became clear to us during the early stages of our work that this type of cycloaddition, although a potentially powerful synthetic tool, had found relatively little general use. Moreover, it was also evident that reviews on various aspects of this chemistry were often out-of-date or Read more…

Chlorine is an element of the halogen family, but it is never found uncombined in nature. It is estimated to account for 0.15 percent of the earth’s crust in the form of soluble chlorides, such as common salt (NaCl), carnallite (KMgCl3 · 6H2O), and sylvite (KCl). In nature, therefore, it exists only as the negative chloride ion with a valence of -1. Chlorine is a most unusual and versatile chemical, as its properties differ so widely in the gaseous, Read more…

The challenge of developing energetic materials that are less sensitive to accidental stimuli continues to be of critical importance. This volume opens with discussions of some determinants of sensitivity and its correlations with various molecular and crystal properties. The next several chapters deal in considerable detail with different aspects and mechanisms of the initiation of detonation, and its quantitative description. The second half of Read more…

Chemical Vapor Deposition (CVD) has developed rapidly in recent years as a method to produce metal films for a variety of applications in the electronics and coatings industries. Originally, it was thought that CVD of all materials was limited by incorporation of carbon and, as a result, the primary applications of CVD would be in the coatings industry where purity is often not a major concern. However, advances in CVD of semiconductors showed that Read more…

In our everyday life we are confronted with different aspects of emulsions—-either water- or oil-continuous—- with varying amounts of oil, fat, and water. Margarine, butter, milk, and dressings all represent central food emulsions. In specific cases involving food emulsions, it is beneficial for the customer to control the stability of the product, particularly with regard to flocculation, sedimentation/ creaming, and coalescence. In other branches Read more…

It is with great pleasure that we accepted the offer by CRC Press to assemble and edit this compilation of reviews on flavonoids and their properties and functions for the present volume. We considered the volume timely in that the last book of this general type, The Flavonoids—Advances in Research Since 1986 (edited by Jeffrey B. Harborne), appeared over a decade ago. Since then, advances in the flavonoid field have been nothing short of spectacular. Read more…

This volume gives a comprehensive overview on the most relevant leukocyte and endothelial adhesion molecules.

Adsorption, Ion Exchange and Catalysis is essentially a mixture of environmental science and chemical reactor engineering. More specifically, three important heterogeneous processes, namely, adsorption, ion exchange and catalysis, are analysed, from fundamental kinetics to reactor design with emphasis on their environmental applications. In Chapter 1, the subject of air and water pollution is dealt with. Data about pollutants and emission sources Read more…

Proteins are unique among the biological macromolecules and have attracted active interest from various disciplines. For the physicist it is the structure that has the characteristics of order as well as of disorder. The chemist is attracted by the unique properties that show up in the catalytic activity of enzymes and in the conversion of chemical into mechanical energy in muscle. Biologists tend to put the emphasis on the functional role of proteins. Read more…
