Martin Stein's thesis describes a novel methodology for natural product discovery. Due to its high degree of reproducibility, robustness and sensitivity, the technique can be utilized to detect even trace amounts of bioactive substances in heterogeneous matrices such as fermentation broths or crude organic extracts. This research is thus relevant for a large number of researchers working in natural product discovery. Applications of this novel NMR-based approach include suitable environmental triggers for the induction of biosynthetic machineries. The author demonstrates the extraordinary value of this approach by the successful isolation of two potent inhibitors of the pharmaceutically relevant proteasome core particle from the insect pathogen photorhabdus luminescens. This thesis has led to a number of publications in high-impact journals.

This updated and expanded Second Edition of Dr. Erickson's Analytical Chemistry of PCBs appears a decade after the first and is completely revised and updated.

This book is a comprehensive review of the analytical chemistry of PCBs. It is part history, part annotated bibliography, part comparison, and part guidance. Featuring a new chapter on analyst/customer interactions and several new appendices, the Second Edition is an invaluable resource for both chemists with no experience in PCB analysis and seasoned PCB researchers.
All topics have been more thoroughly treated and updated in this new edition to reflect advances made in the last decade, especially:

Updated and revised throughout. Second Edition explores the chromatographic methods used for the measurement of drugs, impurities, and excipients in pharmaceutical preparations--such as tablets, ointments, and injectables. Contains a 148-page table listing the chromatographic data of over 1300 drugs and related substances--including sample matrix analyzed, sample handling procedures, column packings, mobile phase, mode of detection, and more.

"Comprehensively covers the design, construction, and operation of gas chromatography, liquid chromatography, and thin-layer chromatography detectors--all in one convenient, up-to-date source. Emphasizes the essential use of common specifications to describe all detectors, allowing easy comparison of their attributes."

Practical Thin-Layer Chromatography provides thorough coverage of the principles, practices, and applications of thin-layer chromatography (TLC) for important sample and compound types. This information is directed specifically at workers in the most active scientific fields.

For many years TLC has suffered from the image of being a low sensitivity, low resolution, non-quantitative teehnique, suitable for chemists, but not a tool for real ehromatographers. Whilst perhaps true in the past this attitude no longer ref1eets the eapabi1ities of modern instrumenta1ized TLC in all its many forms. This volume represents the proceedings of a meeting in Brighton in 1987 whieh formed part of a eontinuing series of one and two day events on TLC organized by the Chromatographie Soeiety either alone or, like this one, in eonjunetion with other learned bodies. These meetings are designed to keep ehromatographers up to date with the latest deve10pments and help promote a more positive image of TLC. lan Wilson November 1987 v CONTENTS The Chromatographic Society xi Contemporary Thin-layer Chromatography: An introduction IoD.

Faba bean is a species of flowering plant in the Fabaceae family and the fourth most widely grown winter season legume after pea, chickpea, and lentil. The nutritional profile of faba beans is excellent as they contain an adequate quantity of proteins, carbohydrates, vitamins, minerals and various polyphenols. Faba bean seeds are a rich source of carbohydrates and starch. Because of higher amylose content than cereal starches, legume starches provide distinctive properties such as high gelation temperature, fast retro-gradation, high resistant starch and gel elasticity to food systems. Faba bean has been a beneficial source of protein in food products worldwide for centuries and continues to be highly produced and consumed to this day. Faba bean Chemistry, Properties and Functionality studies the global status and production of faba bean food products plus their agronomy, nutritional value and potential medicinal applications. The agrarian conditions are studied in full, as are postharvest practices. The chemical makeup of faba bean is a major focus, especially in relation to nutrient composition and quality. Chapters in this text focus on anti-nutritional attributes, antioxidants and bioactive compounds plus the effects of processing, storage and cooking on their nutritional value. Starch and its modification, structure, properties and industrial applications are covered, as is protein, genetic improvement and functional product formulation. The text also looks at the future perspectives of this valuable plant and food source. To date, no reference works have exclusively covered faba bean. This book provides a much-needed single source reference point for researchers looking to gain knowledge on this important plant and its use in high protein, health-beneficial food products.

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.

The rapid growth of the subject since the first edition ten years ago has made it necessary to rewrite the greater part of the book. Except for the introductory portion and the section on Mott scattering, the book has been completely revised. In Chap. 3, sections on polarization violating reflection symmetry, on resonance scattering, and on inelastic processes have been added. Chapter 4 has been rewritten, taking account of the numerous novel results obtained in exchange scattering. Chapter 5 includes the recent discoveries on photoelectron polarization produced by unpolarized radiation with unpolarized targets and on Auger-electron polarization. In Chap. 6, a further discussion of relativistic polarization phenomena has been added to the book. The immense growth of polarization studies with solids and surfaces required an extension and new presentation of Chap. 7. All but one section of Chap. 8 has been rewritten and a detailed treatment of polarization analysis has been included. Again, a nearly comprehensive treatment has been attempted. Even so, substantial selectivity among the wide range of available material has been essential in order to accomplish a compact presentation. The reference list, selected along the same lines as in the first edition, is meant to lead the reader through the literature giving a guide for finding further references. I want to express my indebtedness to a number of people whose help has been invaluable.

This thesis presents results from a combined atomic-resolution Z-contrast and annular bright-field imaging and electron energy loss spectroscopy in the Scanning Transmission Electron Microscopy, as well as first principles studies of the interfaces between crystalline " "" "Si3N4 and amorphous (i) CeO2-x as well as (ii) SiO2 intergranular film (IGF). These interfaces are of a great fundamental and technological interest because they play an important role in the microstructural evolution and mechanical properties of Si3N4 ceramics used in many high temperature and pressure applications. The main contribution of this work is its detailed description of the bonding characteristics of "light" atoms, in particular oxygen and nitrogen, at these interfaces, which has not been achieved before. The atomic-scale information on the arrangement of both light and heavy atoms is critical for realistic modeling of interface properties, such as interface strength and ion transport, and will facilitate increased control over the performance of ceramic and semiconductor materials for a wide-range of applications."

This is the first ever comprehensive treatment of NEXAFS spectroscopy.

This biography gives an insider view of 20th century German science in the making. The discovery by Max von Laue in 1912 of interference effects demonstrated the wave-like nature of X-rays and the atomic lattice structure of crystals. This major advance for research on solids earned him the Nobel Prize two years later, the ultimate acclaim as an exceptional theoretician. As an early supporter of Einstein's relativity theory, he published fundamental papers on light scattering as well as on matter waves and superconductivity. Laue may be counted among the few persons of influence in Germany who - as Einstein put it - managed to "stay morally upright" under Nazism. It is thus surprising that this is the first extensive biography of this famous scientist. Jost Lemmerich could hardly have been better equipped to describe German physics and physicists in the 1920s. His copiously illustrated historical account is based as much on scientific material as on private correspondence, creating a fascinating and convincingly detailed portrait.
