Abstract: A method, in certain embodiments, includes providing a metal alloy, annealing the metal alloy, and contacting the metal alloy with vapors of selenium, or sulfur, or a combination thereof. The metal alloy having a uniform first bulk composition and a first surface composition on annealing provides an annealed metal alloy having a non uniform second bulk composition and a second surface composition which on being contacted vapors of selenium, or sulfur, or a combination thereof, produces a selenized or a sulfurized metal alloy. Further the metal alloy may have a layer formed in situ from a low melting point metal within the alloy via diffusion rather than sequential deposition and co-evaporation.

Abstract: Ceramic HID lamps with improved thermal management having an adherent infrared reflective coating layer located on the outer surface of the vessel are described. They include a coating of a nonmetallic material proximate the first and second end portions of the vessel. Such coatings can minimize temperature gradients during lamp operation. Methods for preparing such lamps with improved thermal management are described as well.

Abstract: Low band gap semiconductor oxides include nanocrystalline porous particles doped with an anion selected from the group consisting of carbon, nitrogen, fluorine, and combinations thereof, wherein the doped nanocrystalline porous semiconductor oxide has a lower band gap energy relative to undoped semiconductor oxides. A combustion synthesis process is used to fabricate the low bang gap materials. Also disclosed herein are dye sensitized solar cells containing the doped semiconductor oxides.

Abstract: A wafer processing apparatus, including a heater apparatus, is provided. The heater apparatus includes a coating layer; and a seal structure in contact with the coating layer. The seal structure is formed from a seal formable material. The seal formable material includes at least one of a YASB glassy composition, a CGYP glassy composition, or a combination of the YASB glassy composition and the CGYP glassy composition. A method and device are also included.

Abstract: A composition is provided that is capable of forming an NZP or an NZP-type coating. The composition includes a first composition, a second composition, and a metal cation. The first composition and the second composition form a crystalline structure with three-dimensional network of octahedra and tetrahedra linked by one or more shared atoms. The first composition comprises one or more of Zr, V, Ta, Nb, Hf, Ti, Al, Cr, or a metal of the Lanthanide series. The second composition comprises at least one of phosphorus, silicon, boron, vanadium or aluminum. The one or more shared atoms comprise at least one of oxygen, nitrogen, or carbon. The first composition and the second composition are related as shown by the formula (first composition)2 (second composition)x (shared atom)12?x. The metal cation is disposed within an interstitial site defined by the crystalline structure.
