摘要： This invention provides a concept of using porous materials on ceramic substrate planarization. This planarized substrate consists of a ceramic substrate, a buffer layer, and a nanostructure layer. The ceramic substrate provides structural strength and surface-mount capability. The buffer layer provides the adhesion between the substrate and the nanostructure layer. The nanostructure layer provides the required surface smoothness of the ceramic substrates for performing thin-film processing techniques and enhances adhesion for metallization and electronic materials.

摘要： A powdered photocatalyst and manufacturing method thereof are disclosed. The manufacturing method of the photocatalytic nanopowders is achieved by the non-transferred DC plasma apparatus in an atmosphere of nitrogen at around 1 atm. The nitrogen-containing gas is used as the plasma-forming gas. After the generation of the nitrogen-plasma in the non-transferred DC plasma apparatus, a plurality of solid Zn precursors are introduced to the nitrogen-plasma for vaporization and oxidization. The solid Zn precursors are vaporized and oxidized through homogeneous nucleation and are rapidly cooled down by a large amount of cooling gas (i.e. mixture of nitrogen and oxygen). After the cooling process, the tetrapod-shaped and nitrogen-doped photocatalytic ZnO nanopowders having wurtzite structure are formed.

摘要： A method for manufacturing powders of oxides in a nanometer level through a direct current plasma thermal reaction is disclosed. The energy required is provided by the plasma that is generated in the non-transferred DC plasma apparatus. Once the solid precursors are introduced into the plasma, the solid precursors are vaporized and oxidized in the plasma reaction region of the non-transferred DC plasma apparatus continuously. Then, the oxide powders in a nanometer scale can form homogeneously and continuously. By controlling the nozzle size, the speed of the plasma can be adjusted and the coarsening and agglomeration of the nanopowders can be effectively prevented. Finally, oxide nanopowders of high-purity and high-dispersity are obtained by cooling down the plasma gas containing the vaporized and oxidized precursor through a vortical cooling-gas.

摘要： The present invention relates to a nanostructured metal powder and a method of fabricating the same. A twin-wire electric arc process is performed to melt the wire tips, and metal melt is formed. Simultaneously, the metal melt is broken up into melt droplets by an atomizing device. The operating temperature of the electric arc process is controlled between melting point and boiling point of the wire, to avoid vaporization of the melt droplets. Then, a fast cooling is performed to quench the melt droplets. Thus, melt droplets are solidified to μm-scaled, spherical and dense powders comprising nano-grains (d
