标题 :Methods for the controlled synthesis of layered lithium and sodium transition metal oxides using electrochemically assisted ion-exchange
发明人：LIU CHONG; HAN YU
权利人:UNIV CHICAGO
摘要:Methods for synthesizing layered lithium transition metal oxides from layered sodium transition metal oxides are provided. Also provided are electrodes for lithium-ion batteries that include the layered lithium transition metal oxides. Similarly, methods for the synthesis of layered sodium transition metal oxides from layered lithium transition metal oxides and electrodes for sodium-ion batteries that include the layered sodium transition metal oxides are provided. The methods couple electrochemical intercalation of alkali ions (Li+ or Na+) with ion-exchange to overcome the kinetic limitation of ion-exchange in the layered alkali transition metal oxides at low vacancy concentrations.

摘要:Methods for forming samples of noble metal bipyramid nanocrystals having very low size and shape polydispersities from samples of mixed noble metal nanocrystals are provided. The samples include those comprising high purity, substantially monodisperse, plasmonic gold bipyramid nanocrystals. Also provided are methods of growing secondary twinned metal nanocrystals using the noble metal bipyramid nanocrystals as seed particles. Like the seed bipyramid nanocrystals from which they are grown, the secondary nanocrystals are twinned nanocrystals and may also be characterized by very low size and shape polydispersities. Secondary twinned nanocrystals grown by these methods include enlarged metal bipyramid nanocrystals and nanocrystals with anisotropic “dumbbellâ€? shapes having a variety of tip geometries. Methods for using noble metal bipyramid nanocrystals as plasmonic heaters to heat reaction solutions via plasmonic-photothermal radiation-to-heat conversion are also provided.

摘要:In one aspect, the present disclosure pertains to methods of making various noble metal nanoprisms, e.g., gold nanoprisms. In various aspects, the methods can comprise incubating, under dark conditions, a growth solution comprising: (a) a plurality of gold seed structures; (b) a gold precursor, and (c) a photocatalytic intermediary, such that during the incubating step multiply-twinned gold seed structures in the growth solution are preferentially enlarged. The disclosed methods can comprise separating the multiply-twinned gold seed structures from the growth solution based upon the size of the gold seed structures to produce an enriched growth solution. In some aspects, the methods comprise irradiating the enriched growth solution to produce the gold nanoprisms. In some aspects, the disclosed nanoprisms comprise silver.

摘要:The present disclosure is related to the development of improved fertilizer for precision and sustainable agriculture. A method was developed wherein efficient NPK nanocomposite for plant nutrition was synthesized in a single step using aerosol science and technology concepts. Further a formulation was prepared by addition of ZnO, TiO 2 and other nanoparticles to the NPK nanocomposite. Also, an aerosol based foliar application technique was developed for the precise delivery of nanoparticles to the plants.
