摘要： An object of the invention is to provide titanium dioxide coloring particles capable of developing colors other than red and yellow while maintaining non-toxicity of titanium dioxide and a titanium dioxide particle mixture containing the titanium dioxide coloring particles, and to provide a method capable of producing the titanium dioxide coloring particles exhibiting the excellent properties by a simple process with a small environmental load. The invention relates to titanium dioxide coloring particles having a brookite type or rutile type crystal structure and co-doped with at least nitrogen and boron, a titanium dioxide particle mixture containing the titanium dioxide coloring particles, and a method for producing the titanium dioxide coloring particles in which a hydrothermal reaction of titanium diboride is caused in presence of an acid or urea, and then a nitriding treatment is performed in an ammonia gas atmosphere or by mixing with urea or carbon nitride.

摘要： Methods and apparatuses for making nanomaterials are disclosed. The methods involve passing one or more source materials through a high pressure and high temperature chamber with an open throat, and then allowing the reactants to expand into a lower pressure, lower temperature zone. The source material is non-stoichiometric and fuel-rich so that excess un-combusted primary source material can form the nanomaterials. In some cases, the apparatus may be in the form of a modified rocket engine. The methods may be used to make various materials including: carbon nanotubes, boron nitride nanomaterials, titanium dioxide, and any materials that are currently produced by flame synthesis, including but not limited to electrocatalysts. The methods may also be used to make nanomaterials outside the Earth's atmosphere. The methods can include making, coating, or repairing structures in space, such as antennae.

摘要： Methods are provided herein for forming transition metal oxide thin films, preferably Group IVB metal oxide thin films, by atomic layer deposition. The metal oxide thin films can be deposited at high temperatures using metalorganic reactants. Metalorganic reactants comprising two ligands, at least one of which is a cycloheptatriene or cycloheptatrienyl (CHT) ligand are used in some embodiments. The metal oxide thin films can be used, for example, as dielectric oxides in transistors, flash devices, capacitors, integrated circuits, and other semiconductor applications.

摘要： Disclosed is a method/system for the production of titanium dioxide particles. The titanium dioxide particles are produced by oxidizing titanium tetrachloride in the presence of an agent which includes ultrafine titanium dioxide particles, and optionally, the presence of a Group 1a metal compound. The presence of the agent, with or without the optional Group 1a metal compound, also serves to control the particle size of the produced titanium dioxide particles.
