    摘要： The present invention discloses metallic fiber boards having catalytic functionality and processes for producing the same. The boards are formed from a mesh of metallic fibers, each fiber having a first layer of an oxide and a second layer of a porous oxide. A catalyst, either disposed on the surface of the second layer, or dispersed within the second layer, provides catalytic functionality to the fiber board. The first layer is produced by thermal oxidation of the metallic fibers, while the second layer and catalyst are produced by thermal decomposition of precursor materials applied to the fiber board while in solution, typically as a spray of atomized droplets. The resulting boards are used to catalyze the combustion of hydrocarbons, especially methane, and particularly in household boilers.

    摘要： A process for producing a field emitter flat display includes providing a supported porous layer of a non-evaporable getter material by depositing the non-evaporable getter material on a substrate followed by sintering the deposited material. The substrate having the porous layer of non-evaporable getter material thereon is then housed in an inner space defined by opposing plates. The inner space is then evacuated and hermetically sealed. The non-evaporable getter material is preferably deposited by preparing a suspension of non-evaporable getter material particles in a suspending medium, coating a surface of a substrate with the suspension by, e.g., spraying, and sintering the coating.

    摘要： A powder of a composite material comprising a non-evaporable getter material with a palladium coating continuously sorbs hydrogen. Embodiments in which the coverage of the palladium coating over the particles of the NEG material is complete can sorb hydrogen without the need for an activation treatment. Other embodiments in which the palladium coverage is less than total but greater than about 10% can also sorb gaseous species other than hydrogen. Loose powders, pressed powders, and sintered powders of the composite material are incorporated into getter devices and into the evacuated spaces of double-walled pipes, dewars, and thermal bottles. Methods for preparing powders of these composite materials utilize evaporative, sputter, and CVD deposition techniques. Another method prepares powders of the composite material by a liquid phase impregnation process.
