摘要： Layers of a passivating material and/or containing luminescent centers are deposited on phosphor particles or particles that contain a host material that is capable of capturing an excitation energy and transferring it to a luminescent center or layer. The layers are formed in an ALD process. The ALD process permits the formation of very thin layers. Coated phosphors have good resistance to ambient moisture and oxygen, and/or can be designed to emit a distribution of desired light wavelengths.

摘要： In an embodiment, a method of conducting a high temperature chemical reaction that produces hydrogen or synthesis gas is described. The high temperature chemical reaction is conducted in a reactor having at least two reactor shells, including an inner shell and an outer shell. Heat absorbing particles are included in a gas stream flowing in the inner shell. The reactor is heated at least in part by a source of concentrated sunlight. The inner shell is heated by the concentrated sunlight. The inner shell re-radiates from the inner wall and heats the heat absorbing particles in the gas stream flowing through the inner shell, and heat transfers from the heat absorbing particles to the first gas stream, thereby heating the reactants in the gas stream to a sufficiently high temperature so that the first gas stream undergoes the desired reaction(s), thereby producing hydrogen or synthesis gas in the gas stream.

摘要： Titanium dioxide particles are coated first with an interstitial coating and then with silicon dioxide or alumina. The coatings are suitably applied via an atomic layer deposition process. The interstitial coating preserves the bright white coloration of the particles after they are coated. The particles therefore can be used as pigments and white fillers in polymers, paints, paper and other applications.

摘要： Molten salt reactions are performed by supporting the molten salt on a particulate support and forming a fluidized bed of the supported salt particles. The method is particularly suitable for combusting hydrocarbon fuels at reduced temperatures, so that the formation NOx species is reduced. When certain preferred salts are used, such as alkali metal carbonates, sulfur and halide species can be captured by the molten salt, thereby reducing SOx and HCl emissions.

摘要： A transition metal carbide is formed from a precursor mixture comprising at least one of the group consisting of: a transition metal, a transition metal carbide and a transition metal oxide. The precursor mixture may contain the desired transition metal carbide (e.g., WC), but if the desired transition metal carbide is present in the precursor mixture, there is necessarily a significant amount of another compound such as a transition metal oxide, undesired carbide (e.g., W2C) or transition metal. The method involves forming an admixture by mixing the precursor mixture with a sufficient amount of carbon to carburize the precursor mixture to the transition metal carbide and reacting the admixture in an inert or reducing atmosphere at a temperature for a time sufficient to convert the admixture to the transition metal carbide, wherein the admixture is reacted in the presence of a means to enhance transfer of heat into the admixture, an inert or reducing gas flowing through at least a portion of the admixture or combination thereof.

摘要： A submicrometer transition metal carbonitride is produced having the formula: M.sub.a M'.sub.b M".sub.(1-a-b) (C.sub.1-x) N.sub.x).sub.z wherein M is Ti, Zr or Hf; M' is V, Nb or Ta; M" is Cr, Mo or W; a ranges from 0 to 1; b ranges from 0 to 1 with the proviso that (a +b) is less than or equal to 1; x ranges from about 0.02 to about 0.95 and z ranges from about 0.9 to about 2. The transition metal carbonitride is produced by mixing (a) a transition metal oxide source of a transition metal in the above formula and (b) a carbon source such as carbon black. This mixture is heated at a rate of between about 100K/sec to about 100,000,000K/sec in a nitrogen containing non-oxidizing gas such as nitrogen or nitrogen mixed with argon to an elevated temperature that makes carbothermal reduction of the transition metal oxide source thermodynamically favorable for a residence time sufficient to convert the transition metal oxide source into at least one product selected from the group consisting of (i) a transition metal carbonitride and (ii) a transition metal carbonitride precursor. The product may be exposed to a finishing step involving heating the product to a temperature less than the elevated temperature in a finishing atmosphere such as nitrogen, hydrogen, inert gas or combinations thereof to form submicrometer carbonitrides of higher purity or different stoichiometry.
