标题 :Method for synthesis of colloidal nanoparticles
发明人：STROUSE GEOFFREY FIELDING; GERBEC JEFFREY A; MAGANA DONNY
权利人:UNIV CALIFORNIA
摘要:A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.

标 题:Synthesis of germanium sulphide and related compounds

摘要:The invention relates to synthesis of germanium sulphide glasses and optical devices formed therefrom. In a chemical vapour deposition process, germanium tetrachloride is reacted with hydrogen sulphide at temperatures in the range 450-700° C. to form germanium sulphide. Lower temperatures within this range of 450-550° C. directly produce a glass, whereas higher temperatures within the range of 600-700° C. produce a crystalline powder which can then be reduced to a glass by subsequent melting and annealing. The reaction is preferably carried out at atmospheric pressure or slightly higher. Thin films and bulk glasses suitable for optical waveguides can be formed directly in one processing step as can powders and microspheres. The materials synthesised are of a high purity with low oxide impurities and only trace levels of transition metal ions.

标 题 :Process for the synthesis of ziegler-type catalytic solids or solid constituents of the same
发明人：BRUN CLAUDE
权利人:ATOCHEM ELF SA
摘要:A process is provided for the synthesis of a solid Ziegler catalyst or of a transition metal solid constituent thereof, which entails preparing the solid catalyst or constituent thereof as a suspension in an inert liquid medium by contacting precursors or ingredients of the catalyst or of the constituent in the inert liquid medium in one or more steps, and drying the suspension, and collecting the catalyst or constituent thereof; and wherein the process is conducted in a single multi-function reactor having a longitudinal axis and which can pivot around an axis which intersects perpendicularly with this axis.

摘要:A process for the preparation of polyphosphazenes is provided that includes the cationic solution polymerization reaction of a phosphoranimine, using a main group or transition metal halide, or other appropriate halide salt, including a linear phosphazene salt of any chain length, or a preformed non-phosphazene polymer containing a main or transition metal chloride, as an initiator. In a preferred embodiment, triarmed-star polyphosphazenes having the formula N{RN(H)R'2P-(N=PR'2)n}3 are prepared via this method. Also, a methods for synthesis of the monomer Cl3P=NSiMe3 and cyclic trimer N3P3X6 from the reactants N(SiR3)3 and PX5 are also described.
