  • Publication number: 20110086165
    Abstract: A porous silicon zone is metallized by performing in situ reduction of metallic ions dissolved in an aqueous solution and fixing of the metallic particles obtained on said zone in a single step. This step consists in particular in bringing the solution containing the metallic ions into contact with the zone to be metallized, the surface whereof has previously been functionalized to enable in situ reduction of the metallic ions and fixing of the metallic particles. Functionalization of the porous silicon zone is achieved by grafting two particular and distinct types of chemical functions. The first function used is a chelating chemical function for the metallic ions and/or for the metal corresponding to the metallic ions, whereas the second function is a reducing chemical function for the metallic ions. Such a metallization can be used for producing an electrically conducting porous diffusion layer of a fuel cell.

    Abstract: To make a metal feature, a non-plateable layer is applied to a workpiece surface and then patterned to form a first plating region and a first non-plating region. Then, metal is deposited on the workpiece to form a raised field region in said first plating region and a recessed region in said first non-plating region. Then, an accelerator film is applied globally on the workpiece. A portion of the accelerator film is selectively removed from the field region, and another portion of the accelerator film remains in the recessed acceleration region. Then, metal is deposited onto the workpiece, and the metal deposits at an accelerated rate in the acceleration region, resulting in a greater thickness of metal in the acceleration region compared to metal in the non-activated field region. Then, metal is completely removed from the field region, thereby forming the metal feature.

An average pore diameter at the first surface of the porous substrate is 0.02 to 0.5 ?m, a thickness of the hydrogen-separating layer is 1 to 5 ?m, and a penetration depth of the penetrated portion is 0.05 to 1 ?m, is at least equal to the average pore diameter at the one surface of the porous substrate, and is not larger than one half of the thickness of the hydrogen-separating layer. The hydrogen separator hardly generates defects such as cracks, peeling and the like in the hydrogen-separating layer, is superior in durability, and provides both good hydrogen-separating ability and good hydrogen permeability.

  • Patent number: 7537799
    Abstract: An ink-jettable composition including a palladium aliphatic amine complex solvated in a liquid vehicle can be used in formation of electronic devices. The ink-jettable composition containing a palladium aliphatic amine complex can be jetted onto a substrate in a predetermined pattern. A second composition can also be applied to the substrate using ink-jet printing or other printing techniques, wherein the second composition is applied onto at least a portion of the predetermined pattern. The second composition can include a reducing agent which is capable of reducing the palladium aliphatic amine complex to palladium metal, typically upon the application of heat. The described ink-jettable palladium complex compositions can be stable over a wide range of conditions and allow for the formation electronic devices on a variety of substrates.

  • Publication number: 20090130339
    Abstract: The present invention relates to a method of producing electroconductive electroless plating powder having excellent dispersibility and adherence, and, more particularly, to a method of producing electroconductive electroless plating powder having excellent dispersibility and adherence, using an electroless plating method of forming a metal plating layer on the surface of a base material made of resin powder in an electroless plating solution, wherein an ultrasonic treatment is performed at the time of forming the plating layer. The present invention has advantages in that an aggregation phenomenon, which is generated when the base material made of the resin powder is plated using an electroless plating method, does not occur and a plating reaction can be performed at low temperature, so that it is possible to obtain a compact plating layer and plating powder having improved uniformity and adherence with respect to resin powder.

  • Patent number: 7531215
    Abstract: A method of forming a hydrogen transport membrane to separate hydrogen from a hydrogen containing feed in which a porous ceramic support is formed to support a dense layer of palladium or an alloy of palladium serving as a hydrogen transport material. Isolated deposits of palladium, a palladium alloy or a component of such alloy are produced on a surface of the porous ceramic support that bridge pores within the porous ceramic support without penetrating the pores and without bridging regions of the surface defined between the pores. The isolated deposits of the metal are produced by an electroless plating process.
