Boron and Oxygen
The present issue, Volume 2 of "Boron Compounds" 4th Supplement of the Gmelin Hand book, updates the previous issues by reporting the literature on boron-oxygen systems published up to 1988. For some important recent developments literature is covered through mid-1992; this concerns, for example, the compounds ~-Ba3[B306h and U[B305J which became of interest as materials with nonlinear optical properties. The volume directly com plements the earlier "Boron Compounds" 3rd Supplement Volume 2. In the original literature, alternative formulations are frequently used for the same com pound. This is especially true for many borates. Often, these species are neither completely heteropolar nor cova...
B Boron Compounds
The 3rd supplement continues the updating of the original 20 volumes on boron com pounds published between 1974 and 1979. The first supplement to this series brought the literature closing date uniformly to the end of 1977, whereas the two volumes of the 2nd supplement have extended the literature coverage of boron compounds to 1980. Selection and presentation of data parallel the style selected for the two previous supplement volumes, which appeared in 1980/1 and 1982/3, respectively. The Gmelin Principle of the Last Position is largely adhered to, excepting substituted polyboron species containing boron-boron bonds (all of which are found in Chapter 2 within the system boron-hydrogen). Exa...
B Boron Compounds
The 3rd supplement continues the updating of the original 20 volumes on boron compounds published between 1974 and 1979. The first supplement consisting of 3 volumes covered all the literature uniformly up to the end of 1977, whereas the two volumes of the 2nd supplement have extended the literature coverage of boron compounds to 1980 and the four volumes of the 3rd supplement to 1984. The present volume continues the description of boron compounds with halogens, presenting those with chlorine, bromine and iodine. The compounds with chalcogens are completed here along with those of boron with S, Se, Te and Po. The final chapter on carboranes contains the carboranes themselves, together with metallacarboranes, and in the last section a description of carborane-containing polymers, mostly derived from the three isomeric dicarbadodecarboranes. Volume 4 of the 3rd supplement brings this supplement series to an end. It will be supplemented by a separately appearing index volume, which contains all the boron compounds dealt with in volumes 1 - 4 of this supplement series.

New Results in Numerical and Experimental Fluid Mechanics VII
th This volume contains the papers presented at the 16 DGLR/STAB-Symposium held at the Eurogress Aachen and organized by RWTH Aachen University, Germany, November, 3 - 4, 2008. STAB is the German Aerospace Aerodynamics Association, founded towards the end of the 1970's, whereas DGLR is the German Society for Aeronautics and Astronautics (Deutsche Gesellschaft für Luft- und Raumfahrt - Lilienthal Oberth e.V.). The mission of STAB is to foster development and acceptance of the discipline “Aerodynamics” in Germany. One of its general guidelines is to concentrate resources and know-how in the involved institutions and to avoid duplication in research work as much as possible. Nowadays, this...
Boron and Cl, Br, I, S, Se, Te. Carbonares
This volume encompasses the compounds of boron with Cl, Br, I, S, Se, and Te. The large final chapter treats carboranes and metallocarboranes and gives a listing of carborane-containing polymers. Each chapter continues the corresponding chapter of the preceding supplement series, thus keeping information of the desired topics current. Among the wealth of boron compounds two of these may be especially mentioned: BCl3 and carboranes containing five boron atoms. Boron trichloride has become an important chemical agent, and much is known of its preparation, purification, and application. BCl3 is a preferred boron-supplying compound in chemical vapor deposition to prepare boron carbide or boron nitride. BC13 is also frequently used in dry-etching, boriding, and doping processes, and as a polymerization catalyst. Recent interest in the field of C2B5H7 carboranes and their derivatives stems from detailed investigations on a large number of isomerisation reactions and their mechanisms.
