标题 :Synthesis of nanoparticles
发明人：HAUBOLD STEPHAN; HAASE MARKUS; RIWOTZKI KARSTEN; WELLER HORST; MEYSSAMY HEIKE; IBARRA FERNANDO
权利人:CT ANGEWANDTE NANOTECH CAN
摘要:Methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is nartower which renders a subsequent size-selected separation process superfluous.

标 题:In-Situ Synthesis of Multi-Core Core Electoconductive Powders
发明人：MICHAELS EMILY W; MILLIGAN DEANNA; MORRIS DAVID
权利人:MILLIKEN & CO
摘要:This invention relates to the in-situ synthesis of multi-core electroconductive powders. The multi-core ECPs of the present invention are made using an in-situ synthesis method which eliminates the need for combining mixtures of various types of single-core ECPs in order to achieve the desired end-use product. The multi-core ECPs described herein exhibit very little coloration. They also exhibit low electrical resistivity and contain reduced amounts of antimony.

标 题:System and method for large scale synthesis of metal cyanometallates
发明人：LU YUHAO; PAN WEI; VAIL SEAN; LEE JONG-JAN
权利人:SHARP LABORATORIES AMERICA INC
摘要:A system and method are presented for the large scale synthesis of metal cyanometallates (MCMs). First and second precursor solutions are added to a main reactor, where the first precursor includes M1 metal cations. The second precursor solution includes A X′ M2(CN) Z′ , where M1 and M2 are from a first group of metals and A is from a second group of metals including alkali or alkaline earth metals. In response to stirring the first and second precursors, MCM particles are formed with the formula A X M1 N M2 M (CN) Z .d[H 2 O] ZEO .e[H 2 O] BND , in solution. In response to aging in the secondary reactor, the size of the MCM particles is increases. The aged MCM particles in solution are then transferred to a separation tank, where the aged MCM particles are filtered from the solution and collected. The solution reclaimed from the separation tank back is added back into the main reactor.
