标 题 :Method for synthesizing nanoparticles of metal sulfides
发明人：HYEON TAEGWHAN
摘要:A synthetic method of fabricating highly crystalline and uniform nanoparticles of metal sulfides, doped metal sulfides, and multi-metallic sulfides disclosed, using no-toxic and inexpensive reagents. A typical synthetic method comprises the steps of, synthesis of metal-surfactant complexes from the reaction of metal precursors and surfactant, addition of sulfur reagent to the solution containing said metal-surfactant complexes followed by heating to high temperature, aging at that temperature to produce metal sulfide nanoparticles and completing the formation of synthesis of nanoparticles metal sulfides and multi-metallic sulfides by adding a poor solvent followed by centrifuging.

标题 :Melt impregnation of mixed metal oxide

摘要:The present invention is directed to a process for preparing a cathode active material consisting of a single phase of mixed metal oxide, such as a single phase silver vanadium oxide. The synthesis technique involves first heating the starting materials to melt a decomposable starting constituent. This first heating temperature is held for a period of time sufficient to enable the decomposable starting constituent to melt and completely flow throughout and within the other starting materials. Then, the thusly produced melt impregnated reaction admixture is preferably ground to ensure complete homogeneity of the starting materials, followed by heating to the decomposition temperature of the decomposable starting constituent. To finish the synthesis, the decomposed admixture is heated to an elevated temperature above the decomposition temperature to provide the single phase mixed metal oxide.

摘要:The anionic manganese oxide nanoparticle nucleic acid scavengers are biodegradable anionic scavengers with low cytotoxicity, which are able to scavenge (bind) cell-free nucleic acids (e.g., extracellular ssRNA, dsRNA, and unmethylated DNA), providing treatment for various medical conditions. The main component of the scavenger is manganese oxide, which may be synthesized by using a manganese compound (e.g., manganese acetate) and an acid (e.g., tannic acid) at high temperature (e.g., 100-150°C). Synthesis may be performed by mixing a manganese compound and an acid in water forming a mixture, which is stirred, heated, and allowed to cool. The anionic manganese oxide nanoparticles are extracted from the cooled mixture. The typical size of the resultant nanomaterials ranges from 30 to 100 nm; the zeta potential of the as-prepared nanomaterials is about -20 mV. The nanoparticles have various uses, including administration to a subject to treat inflammation or to treat cancer.
