  • Patent number: 9993804
    Abstract: A catalyst for exhaust gas purification is described which includes a substrate and a catalyst coating layer provided on the substrate. The catalyst coating layer includes first and second metal oxide particles. The first metal oxide particles have a catalyst metal supported thereon, and the second metal oxide particles do not have a catalyst metal supported thereon. The first and second metal oxide particles have a specific particle size. This is because, when the sizes of the particles supporting the catalyst metal remain relatively large but the sizes of the particles not supporting a catalyst metal are minimized, it is possible to decrease the thickness of the catalyst coating layer while maintaining durability and improving gas diffusibility of the coating layer. Therefore, a thickness of the catalyst coating is decreased without decreasing durability, and the catalyst can exhibit high exhaust gas purification performance even under high load conditions.

  • Patent number: 9450239
    Abstract: A method for fabricating intercalated lithium batteries in open air deposits a thin dense layer of amorphous solid-state lithium boride electrolyte directly onto a negative electrode via flame spray pyrolysis. In one embodiment, the negative electrode is attached to a prefabricated positive electrode via hot pressing (embossing), thus forming an intercalated lithium battery. The method significantly improves upon current methods of fabricating thin film solid state batteries by permitting fabrication without the aid of a controlled environment, thereby allowing for significantly cheaper fabrication than prior batch methods.

  • Patent number: 8840863
    Abstract: A method for the synthesis of nano-products, such as atomic titanium oxide wires. The method allows wires of anatase titanium oxide wires to be formed in a range of tunable diameters and aspect ratios in the nanometer and subnanometer size scales. The method also allows the titanium wires to be capped by oleic acid to enhance dispersing and solubility. The method allows the titanium wires to be surface doped with nitrogen species to enhance stability and functionality such as enhanced absorption in the visible wavelength region, which is useful for photodegradation of organic wastes in water by sunlight.

  • Patent number: 8834600
    Abstract: The present invention relates to a zero-waste process for extraction of alumina from different types of bauxite ores and red mud residues and of titanium dioxide from ilmenite. Iron oxide is first reduced to metallic iron above the melting point of C-saturated cast iron alloy which yields a high-C iron alloy and an Al and Ti metal oxide rich slag which is then treated with alkali carbonate to form alkali aluminates and titanates. The alkali aluminates are separated by water leaching from which the hydroxide of alumina is precipitated by bubbling C02. The residue from water leaching is treated with sulphuric acid and Ti02 is precipitated via a hydrolysis route. The process recovers most of the metal values and generates only small quantities of silicious residues at pH 4-5 which can be used for soil conditioning.
