Publication number: 20110053020Abstract: Nanostructured catalysts and related methods are described. The nanostructured catalysts have a hierarchical structure that facilitates modification of the catalysts for use in particular reactions. Methods for generating hydrogen from a hydrogen-containing molecular species using a nanostructured catalyst are described. The hydrogen gas may be collected and stored, or the hydrogen gas may be collected and consumed for the generation of energy. Thus, the methods may be used as part of the operation of an energy-consuming device or system, e.g., an engine or a fuel cell. Methods for storing hydrogen by using a nanostructured catalyst to react a dehydrogenated molecular species with hydrogen gas to form a hydrogen-containing molecular species are also described.Type: ApplicationFiled: November 7, 2008Publication date: March 3, 2011Applicants: WASHINGTON STATE UNIVERSITY RESEARCH FOUNDATION, IDAHO RESEARCH FOUNDATION, INC.Inventors: M.

Publication number: 20100215915Abstract: The synthesis of nanostructures uses a catalyst that may be in the form of a thin film layer on a substrate. Precursor compounds are selected for low boiling point or already exist in gaseous form. Nanostructures are capable of synthesis with a masked substrate to form patterned nanostructure growth. The techniques further include forming metal nanoparticles with sizes <10 nm and with a narrow size distribution. Metallic nanoparticles have been shown to possess enhanced catalytic properties. The process may include plasma enhanced chemical vapor deposition to deposit Ni, Pt, and/or Au nanoparticles onto the surfaces of SiO2, SiC, and GaN nanowires. A nanostructure sample can be coated with metallic nanoparticles in approximately 5-7 minutes. The size of the nanoparticles can be controlled through appropriate control of temperature and pressure during the process. The coated nanowires have application as gas and aqueous sensors and hydrogen storage.Type: ApplicationFiled: June 23, 2006Publication date: August 26, 2010Applicants: Washington State University, Idaho Research Foundation, Inc.Inventors: Grant Norton, David McIlroy

Patent number: 7686865Abstract: Embodiments of a method and a system for recovering a metal, such as uranium, from a metal-containing material are disclosed. The metal-containing material is exposed to an extractant containing a liquid or supercritical-fluid solvent and an acid-base complex including an oxidizing agent and a complexing agent. Batches of the metal-containing material are moved through a series of stations while the extractant is moved through the stations in the opposite direction. After the extraction step, the metal is separated from the solvent, the complexing agent and/or other metals by exposing the extract to a stripping agent in a countercurrent stripping column. The complexing agent and the solvent exit the column and are separated from each other by reducing the pressure. The recovered complexing agent is recharged with fresh oxidizing agent and recombined with fresh or recovered solvent to form a recovered extractant, which is distributed through the extraction stations.Type: GrantFiled: January 12, 2006Date of Patent: March 30, 2010Assignees: Idaho Research Foundation, Inc., Areva NP, Inc.Inventors: Chien M.

Patent number: 7582561Abstract: A method for depositing one or more materials on a substrate, such as for example, a semiconductor substrate that includes providing the substrate; applying a polymer film to at least a portion of a surface of the substrate; and exposing the semiconductor substrate to a supercritical fluid containing at least one reactant for a time sufficient for the supercritical fluid to swell the polymer and for the at least one reactant to penetrate the polymer film. The reactant is reacted to cause the deposition of the material on at least a portion of the substrate. The substrate is removed from the supercritical fluid, and the polymer film is removed. The process permits the precise deposition of materials without the need for removal of excess material using chemical, physical, or a combination of chemical and physical removal techniques.Type: GrantFiled: September 1, 2005Date of Patent: September 1, 2009Assignees: Micron Technology, Inc., Idaho Research Foundation, Inc.Inventors: Chien M.
