The 11th Colloquium on Metallurgical Analysis - a joint venture of the Institute of Analytical Chemistry of the Technical University in Vienna, the Austrian Society for Analytical Chemistry and Microchemistry, the German Metals Society (DGM), and the Society of German Iron and Steel Engineers (VDEh) - was attended by 120 scientists from 12 nations. The major topics covered were surface, micro and trace analysis of materials with a heavy emphasis on metals. According to the strategy of the meeting attention was focussed on an interdisciplinary approach to materials science - combining analytical chemistry, solid state physics and tech nology. Therefore progress reports on analytical techniques (like SIMS, SNMS, Positron Annihilation Spectroscopy, AES, XPS) were given as well as pre sentations on the development of materials (like for the fusion reactor). The majority of the discussion papers centered on the treatment of important technical problems in materials science and technology by a (mostly sophis ticated) combination of physical and chemical analytical techniques. The intensive exchange of ideas and results between the scientists oriented towards basic research and the industrial materials technologists was very fruitful and resulted in the establishment of several scientific cooperations. Major trends in materials analysis were also dealt with in a plenary discussion of which a short summary is contained in this volume. In order to facilitate international communication in the field of materials analysis and in view of the important questions treated in the various contri butions this proceedings volume was edited in English.

Concrete progress deals with the technology that made concrete the most widely used building material in the world in the course of the past hundred years, and the most indispensable for the global socio-economic development in the new millennium. It offers an insight into many people's dedicated, exploratory concrete research, and into strategic planning and management of research and its transfer to engineering practice. This book is introduced by retrospectively highlighting the international history of concrete technology and uses.

Survey of Progress in Chemistry, Volume 9 provides information pertinent to the essential developments in chemistry. This book discusses the several topics related to chemistry, including organic anions, intercalation compounds, water decomposition, and heterocyclic compounds. Organized into four chapters, this volume begins with an overview of the success of two-phase methods, which is illustrated by their general applicability as well as by their simplicity and effectiveness. This text then examines the main characteristic of two-phase methods wherein the reactants are located in two, mutually insoluble phases, an aqueous, and a nonpolar organic phase. Other chapters consider several main variants and terms describing the application of the approach to problems of organic synthesis. This book discusses as well the criteria for the choice of a catalyst in two-phase reactions. The final chapter deals with the major alkaloid structural types derived from plant sources. This book is a valuable resource for organic chemists.
