Investigation of the structure and function of biological molecules through spectroscopic methods is a field rich in revealing, clever techniques and demanding experiments. It is most gratifying to see that the basic concepts are applied to more and more complex systems, making feasible the study of the behaviour of whole systems in relation to molecular disturbances. The analytical potential of spectroscopy and spectroscopic imaging enables species identification of bacteria and tissue recognition. Clear opportunities for in vivo applications become apparent in the medical field. The methods developed in biophysics start to generate spin-off in the direction of biotechnology, where in previous years we have seen this happen for biochemical techniques. New directions are manifest. Tools are being developed to investigate the behaviour of single molecules in interaction with their environment. Individual interactions can now be investigated and individual molecules in complexes can be visualized. Processes that were previously unobservable as a result of ensemble averaging can now be investigated on a single molecule level. Completely new information with regard to molecular behaviour is obtained in this way. The insights amaze us and the prospect that this development will continue is exciting. The 8th European Conference on the Spectroscopy of Biological Molecules is proud to have contributed to the dissemination of these new directions. This proceedings book is an appropriate reflection of the progress obtained so far in the spectroscopy of biological molecules.

The "Gold Standard" in Biochemistry text books. Biochemistry 4e, is a modern classic that has been thoroughly revised. Don and Judy Voet explain biochemical concepts while offering a unified presentation of life and its variation through evolution. It incorporates both classical and current research to illustrate the historical source of much of our biochemical knowledge.

The object ofthis text is to examine, and elaborate on the meaning of the established premise that 'taste is a chemical sense.' In particular, the major effort is directed toward the degree to which chemical principles apply to phenomena associated with the inductive (recognition) phase of taste. A second objective is to describe the structure and properties of compounds with varying taste that allow decisions to be made with respect to the probable nature of the recognition chemistry for the different tastes, and the probable nature of the receptor(s) for those tastes. A final objective is to include appropriate interdisciplinary observations that have application to solving problems related to the chemical nature of taste. Taste is the most easily accessible chemical structure-biological activity relationship, and taste chemistry studies, i.e. the chemistry of sweetness, saltiness, sourness, and bitterness, have application to general biology, physiology, and pharmacology. Because it involves sensory perception, taste is also of interest to psychologists, and has application to the food and agricultural industries. The largest portion of the text is directed toward sweetness as, due to economic and other factors, the majority of the scientific studies are concerned with sweetness. The text begins with a prologue to describe the problems associated with the study of taste chemistry. Then, there is an introductory chapter to serve as an overview of the general interdisciplinary knowledge of the subject. It is followed by a chapter on the fundamental chemical principles that apply to taste induction chemistry.

Observational, experimental and analytical data show that C60, larger fullerenes, and related structures of elemental carbon exist in interstellar space, meteorites, and on Earth and are associated with meteorite in impact events and in carbon-rich environments such as coals (shungite) and bitumen. The existence of natural fullerenes is at best contested and incompletely documented; realistically it is still controversial. Their presence in astronomical environments can be experimentally constrained but observationally they remain elusive. Fullerenes formation in planetary environments is poorly understood. They survived for giga-years when the environmental conditions were exactly right but even then only a fraction of their original abundance survived. Natural fullerenes and related carbon structures are found in interstellar space, in carbonaceous meteorites associated with giant meteorite impacts (including at the Cretaceous-Tertiary boundary) as well as in soot, coal and natural bitumen.
This book provides an up-to-date summary of the state of knowledge on natural fullerenes occurrences and the laboratory techniques used to determine their presence at low concentration in rock samples. It demonstrates that natural fullerenes exist and should be searched for in places not yet considered such as carbon-containing deep-seated crustal rocks.
"Natural Fullerenes and Related Structures of Elemental Carbon" is written for professional astronomers, meteoriticists, earth and planetary scientists, biologists and chemists interested in carbon and hydrocarbon vapor condensation. It is an invaluable resource for practicing research scientists and science teachers in Earth and Planetary Science, Astronomy and Carbon Science.

1 2 Prof. Dr. Vladimir Mikhailovitsh Kolodkin, Prof. Dr.-Ing. Wolfgang Ruck 1 Institute of Natural and Technogenic Disasters, Udmurt State University, Izhevsk (Russia), 2 Institute of Ecology and Environmental Chemistry, University Luneburg (Germany) During the Cold War a whole arsenal of deadly chemical weapons was allowed to build up on both sides of the ideological divide. Happily, today the problems are reversed. Expertise is now required in the field of safe and environment-friendly disposal of chemical weapons and cleaning up of contaminated sites all around the world, but not least in the ex-Soviet-led countries. The participants and speakers to the NATO-Russia advanced research workshop on the "Ecological Risks Associated with the Destruction of nd th Chemical Weapons," hosted by the University of Luneburg on 22 - 26 October, 2003, therefore, came from many different parts of the world. Of the eight countries represented at the workshop, two were ex-Eastern- Block, and six were Western countries. Yet the West was by no means overrepresented. On the contrary, the Russian expert-speaker contingent, with 33 participants, did justice to the size of their country - and to their chemical-weapons problem - and provided the majority of active participants. In all, there were 57 participants, of which 11 dispatched from the TACIS project "The development of the chemical weapons" facility at the detached plant No 4 of OAO Khimprom, Novocheboksarsk."

Agrochemical products and adjuvants are of vital importance in agriculture, to protect food and fibre crops from weeds, insect pests and diseases, in order to feed and clothe the growing world population. In recent years there have been increasing pressures to produce agrochemical formulations which have a lower environmental impact and are safer in use. Enormous changes have taken place in the chemistry and technology of agrochemicals over the last twenty years or so and this book provides a timely review of the most important area of technology in the development of new products. This book covers issues around international product quality and safety standards and describes the current and likely future trends which will carry the industry forward into the next millennium. It brings together well known international experts with many years of practical experience from agrochemical companies, consultancies, academic institutions and regulatory bodies. Chemists and technologists involved in developing new or improved agrochemical formulations will find this book an essential reference in the course of their work. The book will also be of interest to those working in research and development departments of raw material suppliers, as a concise review of this important field.

It was the objective of the ASI on "Advances in High Pressure Studies of Chemical and Biochemical Systems" to present the current status of such studies and to emphasize the advances achieved during the nine years since the previous ASI on "High Pressure Chemistry." These advances are partly due to the improved instrumentation enabling static and dynamic measurements at pressures several orders of magnitude higher than before, and partly due to the more general availability of high pressure equipment. This has led to a remarkable development in various areas of physics and chemistry, and especially in biochemistry. Throughout the presentation of this Advanced Study Institute the emphasis fell on the teaching character of such a summer school, and the contributions in this volume are of such a nature. Following a general introduction to modern high pressure research, a series of chapters on theoretical and experimental studies of gases, fluids and solids at high temperatures and pressures are presented with special emphasis on the physical aspects involved. Instrumentation used in such studies, viz. shock compression, NMR spectroscopy, laser scattering, x-ray and neutron scattering, and vibrational spectroscopy are treated in detail. The subsequent chapters are devoted to the application of high pressure techniques in the broad areas of organic, inorganic and biochemistry_ The formal lectures were supplemented by 29 contributed papers, for which a list of titles is included.

This book presents a thorough and updated treatment of food chemistry based on modern concepts.

The material presented in this book deals with basic mechanisms of free radical reactions in autoxidation processes and anitoxidant suppression of autoxidation of foods, biochemical models and biologi cal systems. Autoxidation in foods and corresponding biological effects are usually approached separately although recent mechanistic developments in the biochemistry and free radical chemistry of per oxides and their precursors tend to bring these two fields closer. Apparent ability of antioxidants in diets to reduce the inci dence of cancer has resulted in scrutiny of autoxidized products and their precursors as possibly toxic, mutagenic and carcinogenic agents. Mechanisms of any of these effects have been barely ad dressed. Yet we know now that free radicals, as esoteric as they were only a few decades ago, are being discovered in foods, biochem ical and biological systems and do play a role in the above-mentioned causalities. The purpose of the Workshop and the resulting book was to give a unifying approach towards study of beneficial and deleterious effects of autoxidation, based on rigorous scientific considerations. It is our hope that the material presented in this book will not only provide a review of the "state of the art" of autoxidation and anti oxidants, but also reflect the interaction which occurred during the Workshop between workers using model sytems, and food and biological systems."

This book contains the lecture notes for the NATO Advanced Research Workshop on th Green Industrial Applications of Ionic Liquids held April 12th_16 , 2000 in Heraklion, Crete, Greece. This was the fIrst international meeting devoted to research in the area of ionic liquids (salts with melting points below 100 0c), and was intended to explore the promise of ionic liquids as well as to set a research agenda for the fIeld. It was the fIrst international meeting dedicated to the study and application of ionic liquids as solvents, and forty-one scientists and engineers from academia, industry, and government research laboratories (as well as six industry observers and four student assistants) met to discuss the current and future status of the application of ionic liquids to new green industrial technologies. It was immediately clear that the number of organic chemists and engineers working in the fIeld needed to be increased. It was also clear that the declining interest in high temperature molten salts and subsequent increase in low melting ionic liquid solvents had not yet taken hold in Eastern Europe. Participants from NATO Partner Countries contributed signifIcant expertise in high temperature molten salts and were able to take back a new awareness and interest in ionic liquid solvents.

During the past few years there has been a marked increase in the use of advanced chemical methods in studies of soil and clay mineral systems, but only a relatively small number of soil and clay scientists have become intimately associ ated and acquainted with these new techniques. Perhaps the most important obstacles to technology transfer in this area are: 1) many soil and clay chemists have had insufficient opportunities to explore in depth the working principles of more recent spectroscopic developments, and therefore are unable to exploit the vast wealth of information that is available through the application of such ad vanced technology to soil chemical research; and 2) the necessary equipment gen erally is unavailable unless collaborative projects are undertaken with chemists and physicists who already have the instruments. The objective of the NATO Advanced Study Institute held at the University of Illinois from July 23 to August 4, 1979, was to partially alleviate these obstacles. This volume, which is an extensively edited and reviewed version of the proceedings of that Advanced Study Institute, is an essential aspect of that purpose. Herein are summarized the theory and most current applications of six different spectroscopic methods to soil and/or clay mineral systems. The instrumental methods examined are Mossbauer, neutron scattering, x-ray photoelectron (XPS, ESCA), nuclear magnetic resonance (NMR), electron spin resonance (ESR, EPR), and photoacoustic spectroscopy. Contributing authors were also lecturers at the Advanced Study Institute, and are each well known and respected authorities in their respective disciplines."
