METHOD FOR FABRICATING ELECTRONIC COMPONENT
A method for fabricating an electronic component includes the steps of: forming a base material layer of, for example, nickel on a base material of copper, copper alloy, aluminium, or aluminium alloy; applying, as a catalyst, one or more metals selected from the group consisting of gold, palladium, platinum, silver, rhodium, cobalt, tin, copper, iridium, osmium, and ruthenium, on the base material layer; and forming a surface layer by an electroless tin plating bath including trivalent titanium as an reducing agent and pyrophosphate salt as a complexing agent. The surface layer has a thickness of 0.5 μm or more.
Self-cleanable transparent conductive surface/film
A self-cleaning transparent conductive surface includes a hydrophobic film and a metal nano-web coupled to the hydrophobic film. The metal nano-web imparts conductive properties to the surface of the film and texturing formed by either the hydrophobic film, substrate or metal nano-web create a super-hydrophobic surface. This super-hydrophobic and conductive surface may be created by etching and layering a metal nano-web over the surface of a hydrophobic film or a rigid substrate, the metal grid may the hydrophobic film or substrate may also be etched in a moth's eye pattern. Both the hydrophobic film or substrate and metal nano-web may be coated in a layer of hydrophobic material to further increase the hydrophobic effect.
Method of Making Copper Foam Ball
A metal foam ball, several millimeters in diameter, is manufactured to have an open-pore structure to absorb fluid (e.g., gas and liquid) such as water or lubricant. As an example, a copper foam ball is manufactured via a freeze casting method using prepared oxide powder slurry where a spherical silica gel mold is used to freeze the slurry, which is subsequently dried at low temperature in vacuum and then sintered at high temperature. For improved oxidation, copper alloy foam ball or copper foam ball coated with tin can also be manufactured through the same method. For improved strength, steel, copper-nickel alloy, or titanium foam ball can also be manufactured through the same method.
Plating method and recording medium
A plating apparatus, a plating method and a recording medium can allow a temperature of a wafer to be uniform within a surface thereof. A plating apparatus 1 includes a substrate holding unit 52 configured to hold a substrate W; a plating liquid supply unit 53 configured to supply a plating liquid M1 to the substrate W; and a solvent supply unit 55a configured to supply a solvent N1 having a different temperature from a temperature of the plating liquid M1 to the substrate W. The solvent N1 is supplied to a preset position on the substrate W from the solvent supply unit 55a after the plating liquid M1 is supplied to the substrate W from the plating liquid supply unit 53.
Bathless metal-composite electroplating
A bathless plating for a conductive material with composite particles or with high surface coverage. The setup for the bathless electro-plating includes a cathode, a composite mixture, a membrane, and an anode. The cathode is a conductive material. The composite mixture comprises a metal salt, an acid, and a composite material. The composite mixture is applied to the cathode. A hydrophilic membrane is applied to the composite mixture. An anode, with oxidizing properties, is applied to the membrane. A current is applied to the bathless setup. Upon removing the current and composite mixture from the cathode, a metal-based composite coating remains on the cathode.

METAL-CNT COMPOSITE, PRODUCTION METHOD AND MATERIALS THEREFOR
According to a first aspect of the invention, a method for producing a metal-CNT composite material is proposed. The method includes providing a layer of CNT by depositing CNT coated with a polyphenol or poly(catecholamine) coating and filling the interstices of the carbon nanotubes layer with a metal so as to form a metal matrix, in which CNT are embedded. The filling is effected by electrode position or by electroless deposition. The polyphenol or poly(catecholamine) coating is crosslinked by metal ions, the metal ions promoting, as metal seeds, adhesion and/or growth of the metal matrix during the filling step. A further aspect of the invention relates to the metal-CNT composite obtainable by the method.
