Patent number: 6808799Abstract: A thermal barrier coating, or TBC (26), and method for forming the TBC (26). The TBC (26) is formed of a thermal-insulating material that contains yttria-stabilized zirconia (YSZ) alloyed with at least a third oxide. The TBC (26) is formed to also contain elemental carbon, and may potentially contain carbides and/or a carbon-containing gas that forms from the thermal decomposition of carbon.

Patent number: 6242107Abstract: A method for etching selected portions of an aluminum-containing layer of a layer stack that is disposed on a substrate. The aluminum-containing layer is disposed below a photoresist mask having a pattern thereon. The method includes providing a plasma processing chamber and positioning the substrate having thereon the layer stack, including the aluminum containing layer and the photoresist mask, within the plasma processing chamber. The method further includes flowing an etchant source gas that comprises HCl, a chlorine-containing source gas, and an oxygen-containing source gas into the plasma processing chamber. The oxygen-containing source gas is preferably CO2. The flow rate of the oxygen-containing source gas is less than about 20 percent of a total flow rate of the etchant source gas. There is also included striking a plasma out of the etchant source gas, wherein the plasma is employed to etch at least partially through the aluminum-containing layer.Type: GrantFiled: June 24, 1999Date of Patent: June 5, 2001Assignee: Lam Research CorporationInventor: Robert J. O'Donnell

Publication number: 20010001218Abstract: A novel construction board composition is disclosed comprising a unique combination of synthetic binders selected for their ability to establish a strengthened permanent bond in the final dry state for use in a construction board composition comprising primarily gypsum, and in a construction board composition comprising an expanded mineral such as Perlite which largely reduces the amount of gypsum over current gypsum construction board formulations, thus reducing the weight while maintaining the strength of the construction board structure. In a preferred embodiment, the lightweight, strengthened gypsum construction board of the present invention also comprises an optional covering veneer that is applied to provide increased strength, moisture resistance, and fire retardency, and the back paper top ply is treated to provide increased flexural strength.Type: ApplicationFiled: December 8, 2000Publication date: May 17, 2001Inventor: Joseph S.

Patent number: 6221476Abstract: Compositions and methods for selectively binding metal ions from a source solution comprise using a polyhydroxypyridinone-containing ligand covalently bonded to a membrane support having the formula M—A—L(HOPO)n. M is a membrane having a hydrophilic surface, A is a covalent linkage mechanism, L is a ligand carrier, HOPO is a hydroxypyridinone appropriately spaced on the ligand carrier to provide a minimum of six functional coordination metal binding sites, and n is an integer of 3 to 6. The separation is accomplished by passing a source solution containing the ions to be separated through a cartridge containing the membrane-ligand composition, causing the selected ions to be complexed to the HOPO ligands and subsequently removing the selected ions from the cartridge by passing an aqueous receiving solution through the cartridge and quantitatively stripping the selected ions from the HOPO ligand.Type: GrantFiled: June 11, 1999Date of Patent: April 24, 2001Assignees: IBC Advanced Technologies, Inc., Millipore CorporationInventors: Ronald L. Bruening, Krzysztof E. Krakowiak, Anthony J. Dileo, Bipin S. Parekh

Patent number: RE37701Abstract: A composite membrane is provided which includes a base material and an ion exchange resin. The base material has a microstructure characterized by nodes interconnected by fibrils, or a microstructure characterized by fibrils with no nodes present. The ion exchange resin substantially impregnates the membrane such that the membrane is essentially air impermeable.Type: GrantFiled: April 4, 2000Date of Patent: May 14, 2002Assignee: W. L.
