Abstract: A method of making a superfine alloy comprises: incorporating a grain growth inhibitor polymeric precursor into a composition for synthesis of a superfine material; synthesizing the superfine material from the composition comprising the incorporated precursor; incorporating an alloy additive into the composition for synthesis of the superfine material before synthesizing the superfine material, or alternatively, into the as-synthesized superfine material to produce a superfine alloy-grain growth inhibitor polymeric precursor composite; and treating the superfine alloy-grain growth inhibitor polymeric precursor composite to convert the grain growth inhibitor polymeric precursor to a grain growth inhibitor.

Abstract: Thick film magnetic/insulating nanocomposite materials, with significantly reduced core loss, and their manufacture are described. The insulator coated magnetic nanocomposite comprises one or more magnetic components, and an insulating component. The magnetic component comprises nanometer scale particles (about 1 to about 100 nanometers) coated by a thin-layered insulating phase. While the intergrain interaction between the immediate neighboring magnetic nanoparticles separated by the insulating phase provides the desired soft magnetic properties, the insulating material provides high resistivity, which reduces eddy current loss.

Abstract: A superfine material made by incorporation of an inorganic polymer precursor of a grain growth inhibitor into intermediates useful for the production of superfine materials. The precursor/nanostructured material composite is optionally heat treated at a temperature below the grain growth temperature of the superfine material in order to more effectively disperse the precursor. The composites are then heat treated at a temperature effective to decompose the precursor and to form superfine materials having grain growth inhibitors uniformly distributed at the grain boundaries. Synthesis of the inorganic polymer solution comprises forming an inorganic polymer from a solution of metal salts, filtering the polymer, and drying. Alloying additives as well as grain growth inhibitors may be incorporated into the superfine materials.

Abstract: A solid oxide fuel cell comprises a dense electrolyte disposed between a porous anode and a porous cathode wherein the dense electrolyte comprises doped lanthanum gallate or yttria stabilized zirconia, the porous anode comprises yttrium-doped strontium titanate, yttrium-doped strontium titanate and nickel, lanthanum-doped ceria and nickel or yttria stabilized zirconia and nickel and the porous cathode comprises doped lanthanum ferrite or strontium-doped lanthanum manganite. The fuel cell may further comprise an interlayer(s) comprising lanthanum-doped ceria disposed between an electrode (anode, cathode or both) and the electrolyte. An interconnect layer comprising doped lanthanum chromate may be disposed between the anode of a first single fuel cell and the cathode of a second single fuel cell. The anode, cathode, electrolyte and optional interlayer(s) are produced by thermal spray.
