Publication number: 20100227187Abstract: A novel solution route has been developed that after heat-treatment to 500-600° C. under inert atmosphere, yields highly porous composites of nano-sized metal (Ni) particle inclusions in ceramics (Al2O3). Metal loadings could be made from <1% to >95% Ni. The metal inclusion sizes in the Ni—Al2O3 system with the 10 atom % Ni sample were 4-7 nm, while for the 75 atom % Ni sample they were 5-8 nm. It was shown that the 10 atom % Ni sample could be used as a catalyst for the conversion of CO2 and CH4 in the temperature range 550-700° C., while higher temperatures led to growth of the Ni particles and carbon poisoning over time. The solution routes could also be deposited as thin dense films containing <10 nm Ni particles. Such films with high Ni-particle loadings deposited on aluminium substrates have shown very good solar heat absorber proficiency and provide good substrates for carbon tube growth.Type: ApplicationFiled: May 21, 2010Publication date: September 9, 2010Applicant: SUNSTRIP ABInventors: GUNNAR WESTIN, Annika Pohl, Asa Ekstrand

Publication number: 20040084112Abstract: Ferromagnetic particles with a high-temperature and thermally stable insulating coating are described. The ferromagnetic particles are first coated with a thin layer of a high permeability metal (nickel) by an electroless plating process. The deposited metal layer is then oxidized by controlling the time and temperature while heating the coated particles in an oxygen atmosphere. This process develops a thin and uniform layer of metal oxide on the ferromagnetic particles. The controlled oxidation of the coating helps encapsulate the particles with a thermally stable and electrically non-conducting layer. These particles can then be compacted and then annealed above 500 degrees Celsius to relieve the stresses introduced in the shaping, thereby obtaining articles with a high permeability and low magnetic loss.Type: ApplicationFiled: November 5, 2002Publication date: May 6, 2004Applicant: General Electric CompanyInventors: Amitabh Verma, Luana Emiliana Iorio, K.

Patent number: 6670049Abstract: An environmental coating is applied to the surface of a titanium-base alloy substrate to protect the surface from oxidation, corrosion, erosion, and other damage. The coating is a mixture of a metal and a ceramic, each selected to contribute to the protective function. The proportions of the metal and the ceramic in the coating are selected such that the coefficient of thermal expansion of the coating is about the same as the coefficient of thermal expansion of the substrate.Type: GrantFiled: May 5, 1995Date of Patent: December 30, 2003Assignee: General Electric CompanyInventors: Jon C.

Patent number: 6667112Abstract: Dental restorations are fabricated using metal powder. Preferably, the metal powder is a high fusing metal and preferably, the metal powder comprises a non-oxidizing metal. The metal powder is applied to a die and is covered with a covering material such as a refractory die material preferably in the form of a flowable paste. A second covering material may be sprinkled or dusted onto the paste. The model is then dried prior to firing. After drying, the model is sintered to provide a high strength metal restoration. After sintering, the outer shell can be broken off easily with one's hand to expose the sintered coping.Type: GrantFiled: July 24, 2001Date of Patent: December 23, 2003Assignee: Pentron Laboratory Technologies, LLCInventors: Arun Prasad, Gregg Daskalon

Patent number: 6569529Abstract: Interference pigment flakes and foils are provided which have color shifting properties. The pigment flakes can have a symmetrical coating structure on opposing sides of a reflector layer, can have an asymmetrical coating structure with all of the layers on one side of the reflector layer, or can be formed with encapsulating coatings around a core reflector layer. The coating structure of the flakes and foils includes a reflector layer, a dielectric layer on the reflector layer, and a titanium-containing absorber layer on the dielectric layer. The pigment flakes and foils exhibit a discrete color shift so as to have a first color at a first angle of incident light or viewing and a second color different from the first color at a second angle of incident light or viewing. The pigment flakes can be interspersed into liquid media such as paints or inks to produce colorant compositions for subsequent application to objects or papers.Type: GrantFiled: October 10, 2000Date of Patent: May 27, 2003Assignee: Flex Product, Inc.Inventors: Roger W.
