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 alpha-alkoxycarboxylic acids
发明人：LAI JOHN T
权利人:GOODRICH CO B F
摘要:Numerous alpha-carboxylic acids are prepared in a liquid medium by the reaction of an organic compound having at least one reactive hydroxyl or thiol group, with a monoketone, and a haloform, in the presence of a phase transfer catalyst and an alkali metal hydroxide. The term 'alpha-alkoxycarboxylic acids' includes alpha-phenoxycarboxylic acids, alpha-thioalkoxycarboxylic acids and alpha-thiophenoxycarboxylic acids. Specific substituents on the beta carbon atom of an alpha-alkoxycarboxylic (or '2-alkoxycarboxylic') acid reaction product formed in this novel synthesis, are introduced by appropriate choice of the ketone reactant; alkoxy and phenoxy substituents on the alpha carbon atom of a 2-alkoxycarboxylic acid are introduced by appropriate choice of the organic compound having a hydroxyl or thiol group. De-alkoxylation of the 2-alkoxycarboxylic acid yields alpha-beta monoolefinically unsaturated carboxylic acids which are necessarily alpha substituted, and may also be beta-substituted. It is now possible to produce, simply and conveniently, numerous substituted alpha-beta monolefinically unsaturated carboxylic acids with a variety of substituents on the alpha carbon atom, and, optionally on the beta carbon atom of these substituted carboxylic acids. Esters may also be conventionally derived from both the 2-alkoxycarboxylic acids, and the unsaturated carboxylic acids. During the phase transfer catalyzed synthesis of this invention, an intermediate acyl halide derivative is formed prior to the formation of the 2-alkoxycarboxylic acid reaction product. The formation of the acyl halide derivative allows the subsequent direct formation, in a modification of the same reaction, of 2-alkoxycarboxylic acid amides (or '2-alkoxycarbamides'), simply by adding a primary or secondary amine to the reaction mass. By dealkoxylation of the 2-alkoxycarbamides, specific, necessarily alpha-substituted and optionally beta-substituted acrylamides are synthesized which previously could be prepared, if at all, only with difficulty.

标 题 :Template-assisted synthesis of 2D nanosheets using nanoparticle templates
发明人：DANIELS STEVEN; PICKETT NIGEL L
权利人:NANOCO TECHNOLOGIES LTD; NANOCO 2D MAT LIMITED
摘要:A template-assisted method for the synthesis of 2D nanosheets comprises growing a 2D material on the surface of a nanoparticle substrate that acts as a template for nanosheet growth. The 2D nanosheets may then be released from the template surface, e.g. via chemical intercalation and exfoliation, purified, and the templates may be reused.
