摘要:Provided are methods to convert—through a bottom-up approach—binary and ternary titanium carbides, nitrides, borides, phosphides, aluminides, and silicides into lepidocrocitic nanofilaments that in some cases self-assemble into 2D flakes by immersing them in a quaternary ammonium solution at moderate temperatures. The resulting flakes can comprise nanofilaments in cross-section, some of which nanofilaments can be few microns long in some instances.

摘要:A composition includes an aqueous solution including at least one fluorinated organic compound; and a reaction product of a source of iron(II) and a source of sulfite in the presence of water and molecular hydrogen. A method of making a catalyst includes reacting a source of iron(II) and a source of sulfite in the presence of water and molecular hydrogen. The water may include less than or equal to 1 weight percent dissolved molecular oxygen. The catalyst may be used for degrading fluorinated organic chemicals in aqueous media.

摘要:Provided are methods to convert - through a bottom-up approach – binary and ternary titanium carbides, nitrides, borides, phosphides, aluminides, and silicides into nanofilaments that in some cases self-assemble into 2D flakes by immersing them in a quaternary ammonium solution at moderate temperatures. The resulting flakes can be C-containing anatase-based layers that are in turn comprised of nanofilaments in cross-section, some of which nanofilaments can be few microns long in some instances. Electrodes made from these materials performed well in energy systems. The materials also reduce the viability of some cancer cells. Also provided are mesoporous materials, devices, and related methods.

摘要:The invention relates to a continuous process for preparing carbon-coated lithium-iron-phosphate particles, wherein the carbon-coated lithium-iron-phosphate particles have a mean (d 50 ) particle size of 10 to 150 nm, and wherein the carbon-coating is an acetylene-black coating, comprising performing in a reactor a flame-spray pyrolysis step (i) in a particle formation zone of the reactor, and a carbon-coating step (ii) in a carbon-coating zone of the reactor, wherein inn (i) a combustible organic solution containing a mixture of lithium or a lithium compound; iron or an iron compound; and phosphorus or a phosphorous compound in an organic solvent, is fed through at least one nozzle where said organic solution is dispersed, ignited and combusted, to give a flame spray thereby forming an aerosol of lithium iron phosphate particles; (ii) acetylene gas is injected into said aerosol thereby forming an acetylene-black coating on the lithium iron phosphate particles; (iii) the coated particles are cooled by an inert quench gas and collected on a filter.

摘要:Disclosed is a method of manufacturing multilayer graphene, including (a) contacting of a metal substrate with a nonmetal element, (b) reduction through heat treatment, and (c) chemical vapor deposition of a graphene precursor on the metal substrate containing the nonmetal element dissolved therein, thereby manufacturing multilayer graphene that is doped with the nonmetal element on the metal substrate. In the multilayer graphene thus manufactured, the number of graphene layers and the work function are simultaneously adjusted by controlling the concentration of doped nonmetal element in a thickness direction of graphene through interactions related to the reduction of the nonmetal element dissolved in a copper catalyst and the growth of graphene, and moreover, the stacking structure of graphene is maintained and the optoelectronic properties of multilayer graphene can be controlled by simultaneously regulating graphene growth and doping during the synthesis procedure without additional processing.
