Die Stille-Reaktion ist eine der sehr wenigen Reaktionen, in denen unter milden Bedingungen Kohlenstoff-Kohlenstoff-Bindungen geknüpft werden können. Man verwendet die Reaktion häufig in der Synthese komplizierter Moleküle zur Verknüpfung größerer Molekülbausteine. Die Autoren diskutieren vom präparativen Standpunkt aus Grenzen, Einflüsse, strukturelle Effekte und die Wahl der geeigneten Reaktionsbedingungen. Mit ausführlichen Vorschriften und vielen Beispielen. (11/98)

Here, the editors Rolf Gleiter and Henning Hopf present an excellent overview of all the important aspects and latest results in cyclophane chemistry. Clearly structured and covering the entire range, the book introduces readers to the most recent research in the field. Twenty chapters, written by well-known scientists, cover in particular: - synthesis of carbo- and heterocyclic cyclophanes and metallocenophanes, - structural and spectroscopic properties of cyclophanes, - current and future applications in synthesis and material science, - novel reactions of cyclophanes, - use of cyclophanes as building blocks in supramolecular chemistry for this fascinating class of compounds. Thus, this is not only an extremely valuable source of information for synthetic organic chemists, but also a ready reference for scientists working in related fields of arene chemistry, stereoselective synthesis, material science, and bioorganic chemistry.

Municipal and industrial wastewaters contain a wide spectrum of pollutants. Their effective removal presents a challenge for water treatment technology. Biosorption of nutrients and pollutants has been used in sewage treatment since the discovery of the activated sludge process. It is a passive uptake process by which pollutants are adsorbed on the surface of cell walls and/or dissolved in structures of microorganism cells that are present in sludge. Sorbed pollutants remain in the sludge and can be potentially released back into the environment depending on their condition and the reversibility of the pollutant-sludge interaction. An overview of typical biosorption applications for the removal of nutrients, organic pollutants, and metals in wastewater treatment is provided in different areas of their use for the protection of aquatic ecosystems and human health. This book will be of interest to operators of wastewater treatment plants and sludge treatment and disposal facilities as well as to researchers and university students in the field of environmental engineering.

This new edition includes an update on HIV disease/AIDS, recently developed HIV rapid tests to diagnose HIV infection and screen donor blood, and current information on antiretroviral drugs and the laboratory monitoring of antiretroviral therapy. Information on the epidemiology and laboratory investigation of other pathogens has also been brought up to date. Several new, rapid, simple to perform immunochromatographic tests to assist in the diagnosis of infectious diseases are described, including those for brucellosis, cholera, dengue, leptospirosis, syphilis and hepatitis. Recently developed lgM antibody tests to investigate typhoid fever are also described. The new classification of salmonellae has been introduced. Details of manufacturers and suppliers now include website information and e-mail addresses. The haematology and blood transfusion chapters have been updated, including a review of haemoglobin measurement methods in consideration of the high prevalence of anaemia in developing countries.

This exceptionally well-illustrated book at a high scientific level describes mud volcanism as a complex, multidimensional phenomenon requiring multidisciplinary study. Mud volcanoes can be used as “cheap windows” to search for gas-hydrates and other mineral resources in the Black Sea region. Nothing similar has been published before, and as one of its unique features the book includes a vast amount of new data unavailable so far to the western reader. The book includes new data on driving forces, mechanisms, origin, geological and geomorphological features of mud volcanoes as well as new data on composition of solid, gaseous, and liquid components of erupted material. It covers a wide geographic region, and its subjects range from geological to environmental to industrial applications.

Photochromism is the reversible phototransformation of a chemical species between two forms having different absorption spectra. During the phototransformation not only the absorption spectra but also various physicochemical properties change, such as the refractive index, dielectric constant, oxidation/reduction potential, and geometrical structure. The property changes can be applied to photonic equipment such as erasable memory media, photo-optical switch components, and display devices. This book compiles the accomplishments of the research project titled “New Frontiers in Photochromism” supported by the Ministry of Education, Culture, Sports, Science and Technology of Japan. The project focused not only on the above-mentioned classical subjects in photochromism, such as color changes, optical memory, and optical switches, but also on fundamental physicochemical studies and unprecedented application fields that have not yet been explored in photochromism. The latter topics include light-driven mechanical motion, photocontrol of surface wettability, metal deposition on solid materials, photocontrol of chiral properties, ultrafast decoloration dyes, and femtosecond laser experiments, among others.
