标题 :Synthesis of nanoparticles

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.

发明人：BLUMBERG SHAWN T; DORSEY CHRISTOPHER L
权利人:SOUTHWEST RES INST
摘要:A synthesis of bis-oxime heterocycles via reaction of 2,4-dimethyl pyridine or 2,4-dimethylpyrimidine in the presence of a phase transfer catalyst. Such bis-oxime heterocycles provide a more direct route to the synthesis of bis-quaternary pyridinium compounds and their analogs as nerve agent antidotes.
