Abstract: Dispersed powders are disclosed that comprise fine nanoscale powders dispersed on coarser carrier powders. The composition of the dispersed fine powders may be oxides, carbides, nitrides, borides, chalcogenides, metals, and alloys. Fine powders discussed are of sizes less than 100 microns, preferably less than 10 micron, more preferably less than 1 micron, and most preferably less than 100 nanometers. Methods for producing such powders in high volume, low-cost, and reproducible quality are also outlined. Such powders are useful in various applications such as catalysts, sensor, electronic, electrical, photonic, thermal, biomedical, piezo, magnetic, catalytic and electrochemical products.

Abstract: A thermally conductive polymer sheet includes a polymer matrix and graphitized carbon fibers as a thermally conductive filler. The graphitized carbon fibers are formed by spinning, infusibilization, carbonization, pulverized mesophase pitch before graphitizing the mesophase pitch. The graphitized carbon fibers have a coating layer of ferromagnetic material on their surface. The application of magnetic field to the coating layer allows the fibers to be oriented to be perpendicular to the sheet. Preferably, by X-ray diffractometry, the graphitized carbon fibers have an interplanar spacing (d 002 ) of graphite planes of less than 0.3370 nm and a ratio (P 101 /P 100 ) of diffraction peak ( 101 ) to diffraction peak ( 100 ) of at least 1.15. The ferromagnetic material is preferably at least one of a metal, an alloy, or a compound selected from the group consisting of nickel, cobalt and iron.

Abstract: An electron-emitting source includes a substrate and a coating film. The substrate is made of a material containing a metal serving as a growth nucleus for nanotube fibers as a main component, and has a plurality of through holes. The coating film is constituted by nanotube fibers formed on a surface of the substrate and wall surfaces of the through holes. A method of manufacturing an electron-emitting source is also disclosed.

Abstract: The electron-source array of the present invention is provided with cathode electrodes placed on an insulation substrate in the form of lines; and gate electrodes that are placed face to face with the cathode electrodes with the insulation film being interpolated in between. In this arrangement, the cathode electrodes and the gate electrodes are arranged so as to intersect each other with a pore being formed at an intersecting portion between each cathode electrode and each gate electrode in a manner so as to penetrate the insulation film, and the pore is filled with a conductive material or a semiconductive material with the material being electrically connected to the corresponding cathode electrode, and is formed in a manner so as to separate from the gate electrodes with a space in between. Thus, it becomes possible to form very fine emitters uniformly without the need for a high-precision patterning technique and consequently to provide an electron-source array that enables an X-Y matrix driving process.
