专利号:US-2019134585-A1 优先权日:2016-05-09 标题:Synthesis of oxygen and boron trihalogenide functionalized two-dimensional layered materials in pressurized medium 发明人:NEMETH KAROLY; DANBY ANDREW M; SUBRAMANIAM BALA 权利人:BORON NITRIDE POWER LLC; UNIV KANSAS 摘要:A method that uses a pressurized reactive medium composed of inert solvents such as pressurized liquid or supercritical fluid carbon dioxide (C02), and sulfur hexafluoride (SF6) and reactive dissolved species ozone (03) and/or boron trifluoride (BF3) and general boron trihalogenides (BX3) to react with two-dimensional (2D) layered materials and thereby synthesize covalently oxygen and/or BX3 functionalized exfoliated 2D layered materials. When 2D layered materials are dispersed in these reactive liquids or fluids by ultrasound sonication or high shear mixing, a simultaneous covalent functionalization and exfoliation of the 2D layered materials happens. Following attainment of the required extent of functionalization and exfoliation, the unreacted 03, BX3, SF6 and C02 can be easily removed as gases by decompression leaving behind the solid phase, thereby leading to efficient and economical production of functionalized and exfoliated 2D layered materials.

The resulting flakes can comprise nanofilaments in cross-section, some of which nanofilaments can be few microns long in some instances.

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.
专利号:US-9790093-B2 优先权日:2016-01-19 标题:High-yield synthesis of nanostructured boron phosphide by a pyrotechnic method 发明人:LUAN ZHAOHUA; MORRIS LAUREN A; SHAW ANTHONY P; HAINES CHRISTOPHER D; PORET JAY C 权利人:US ARMY 摘要:A simplified method for synthesizing boron phosphide at high yields. The method requires mixing of boron phosphate and magnesium metal without diluents into a homogenous mixture, loosely packing the mixture at less than 20,000 psi and igniting the mixture using an energy input that is not greater than 20% of the reaction energy output to create a self-propagating high-temperature reaction wherein the boron phosphate and magnesium metal is completely burned during the reaction to synthesize boron phosphide at high yields.
专利号:EP-0322217-B1 优先权日:1987-12-21 标题 :Diamond synthesis 摘要:Large diamond crystals are produced in a reaction vessel which contains a tetrahedrally bonded crystalline non-diamond seed material (30) separated from a source (26) of substantially pure carbon by a mass (24) of metallic catalyst/solvent for diamond synthesis. The arrangement is such that a temperature gradient is created between the seed material (30) and the carbon source (26) under the applied conditions of temperature and pressure such that the seed material is located at a point near the minimum value of temperature for the gradient and the carbon source is located at a point near the maximum value of temperature for the temperature gradient. Examples of suitable non-diamond seed material are cubic boron nitride and alpha -silicon carbide.
专利号:US-8801979-B2 优先权日:2010-06-10 标题:Apparatus and method for continuous production of materials 发明人:CHANG CHIH-HUNG; JIN HYUNGDAE 权利人:CHANG CHIH-HUNG; JIN HYUNGDAE; OREGON STATE 摘要:Embodiments of a continuous-flow injection reactor and a method for continuous material synthesis are disclosed. The reactor includes a mixing zone unit and a residence time unit removably coupled to the mixing zone unit. The mixing zone unit includes at least one top inlet, a side inlet, and a bottom outlet. An injection tube, or plurality of injection tubes, is inserted through the top inlet and extends past the side inlet while terminating above the bottom outlet. A first reactant solution flows in through the side inlet, and a second reactant solution flows in through the injection tube(s). With reference to nanoparticle synthesis, the reactant solutions combine in a mixing zone and form nucleated nanoparticles. The nucleated nanoparticles flow through the residence time unit. The residence time unit may be a single conduit, or it may include an outer housing and a plurality of inner tubes within the outer housing.
