Tailor Made Silicon Oxygen Compounds

The title "Tailor-Made Silicon-Oxygen Compounds - From Molecules to Materials" was the topic of a workshop at the Centre of Interdisciplinary Research (ZiF) in Bielefeld, organized by the editors of the monograph. The field of SiO compounds is actually very exciting and rapidly developing. About 25 leading scientists from different areas (molecular chemistry, solid-state chemistry, material science, physical and theoretical chemistry) present newest results and scientific perspectives within the following subdisciplines: Fundamental SiO-systems; siloxenes; silicon monoxide; functionalized siloxanes; silicate assembly; siloxane assembly. Der Titel "Tailor-Made Silicon-Oxygen Compounds - From Molecules to Materials" ist das Thema eines Workshops, der am Zentrum für interdisziplinäre Forschung (ZiF) in Bielefeld stattfand und von den Herausgebern des Buch organisiert wurde. Die Forschung auf dem Gebiet der Silicium-Sauerstoff-Verbindungen ist äußerst aktuell und entwickelt sich rasant. Etwa 25 Wissenschaftler aus verschiedenen Bereichen (Molekülchemie, Festkörperchemie, Materialwissenschaften, Physikalische und Theoretische Chemie) präsentieren neueste Ergebnisse und wissenschaftliche Perspektiven auf den folgenden Teilgebieten: Si-O-Basissysteme, Siloxen, Siliciummonoxid, funktionalisierte Siloxane, komplexe Silikat-Strukturen, komplexe Siloxan-Strukturen

The combined results from an international research project involving 40 interdisciplinary groups, providing the latest knowledge from the past few years. Adopting an application-oriented approach, this handy reference is a must-have for every silicon chemist, whether working in inorganic, organic, physical or polymer chemistry, materials science or physics.

Although ceramics have been known to mankind literally for millennia, research has never ceased. Apart from the classic uses as a bulk material in pottery, construction, and decoration, the latter half of the twentieth century saw an explosive growth of application fields, such as electrical and thermal insulators, wear-resistant bearings, surface coatings, lightweight armour, and aerospace materials. In addition to plain, hard solids, modern ceramics come in many new guises such as fabrics, ultrathin films, microstructures and hybrid composites. Built on the solid foundations laid down by the 20-volume series Materials Science and Technology, Ceramics Science and Technology picks out this exciting material class and illuminates it from all sides. Materials scientists, engineers, chemists, biochemists, physicists and medical researchers alike will fi nd this work a treasure trove for a wide range of ceramics knowledge from theory and fundamentals to practical approaches and problem solutions.

Silicon and silicon compounds have contributed decisively to the technical progress. Technical applications range from mass commodities to highly sophisticated special materials, from ceramics to polymers, from medicine to microelectronics. To keep pace with scientific and technical developments Germany and Austria have established national priority programs, strongly linked to each other as well as to some Swiss groups. At mid-term of the German program and the end of the first funding period of the Austrian program the results are summarized in this special edition of the journal Monatshefte für Chemie/Chemical Monthly, giving an excellent overview of the current chemical (and partly physical) acitivites in the joint Austrian/German/Swiss program. The contributions cover topical and interdisciplinary developments in the following areas: • new phenomena in compounds with Si-Si bonds: transitions between molecular compounds and solids, cyclosilanes, polysilanes, silicides, amorphous hydrogenated silicon, • novel silicon-oxygen systems: functionalized sol-gel compounds, spherosiloxanes, siloxene, • compounds with low- and high-coordinated silicon, • new spectroscopic and analytical techniques for the characterization of molecular and polymeric silicon compounds.

Within this text, for the first time the synthesis, structural characteristics, physical properties, applications and potential applications of polysiloxanes, polycarbosilanes, polysilazanes, polysilanes, and other silicon-containing polymers are detailed. For years to come this book will be the first point of entry for those seeking to learn about the very significant differences that exist between carbon-based polymers and those with silicon in their backbone.

This widely-acclaimed serial contains authoritative reviews that address all aspects of organometallic chemistry, a field which has expanded enormously since the publication of Volume 1 in 1964. Almost all branches of chemistry and material science now interface with organometallic chemistry--the study of compounds containing carbon-metal bonds. Organometallic compounds range from species which are so reactive that they only have a transient existence at ambient temperatures to species which are thermally very stable. Organometallics are used extensively in the synthesis of useful compounds on both large and small scales. Industrial processes involving plastics, polymers, electronic materials, and pharmaceuticals all depend on advancements in organometallic chemistry.

This book presents the foundations of the science of polymer derived ceramics, enriched with many descriptions of applications. Written by a team of selected researchers, the text is a systematic, comprehensive introduction to all phases of polymer derived ceramics from synthesis strategies through properties measurement, and applications. New material is given on the nanolevel structure of PDCs, and it is shown how nano-sized modifications can alter and improve the properties of polymer derived ceramics, including high chemical durability, oxidation resistance, luminescence, and piezo-resistivity. Groundbreaking work is also described on novel precursors such as stoichiometric SiC, BN, and SiBCN ceramics. In terms of technology, this volume explains how PDCs are fabricated and how these novel materials are used in membranes, filters, MEMS, fibers, and micro-components. This book covers: synthesis, structure, properties and applications; strategies for characterizing and synthesizing PDCs; and, original research on pre-ceramic PDC precursors.
