  • Patent number: 9254505
    Abstract: A variety of methods, devices, systems and arrangements are implemented involving nanowire meshes. One such method is implemented to include synthesizing metal nanowires in a solution containing a structure-directing agent. The metal nanowires are deposited on a substrate to form a sheet of nanowires. The deposited metal nanowires are heated to a temperature less than about 200 degrees Celsius and for a period of time of about 10 minutes to 60 minutes, thereby removing the structure-directing agent and modifying the electrical conductivity and optical transmittance of the sheet of nanowires.

    Abstract: A method for fabricating nanostructures, which includes the steps of forming a multi-segmented nanowire; and performing a galvanic displacement reaction on the multi-segmented nanowire. The method utilizes template directed electrodeposition to fabricate nanowires with alternating layers of sacrificial/noble metal, enabling a new level of control over particle spacing, aspect ratio, and composition. Moreover, by exploiting the redox potential dependent reaction of galvanic displacement, nanopeapod materials can be extended (semiconductor/metal, p-type/n-type, metal/metal, ferromagnetic/nonmagnetic, etc.) beyond the fundamental metal/metal-oxide nanopeapods synthesized by high temperature techniques. In accordance with an exemplary embodiment. Co/Au and Ni/Au multisegmented nanowires were used to create Te/Au nanopeapods by galvanic displacement, producing Te nanotubes and nanowires with embedded Au particles, respectively.

  • Patent number: 8043719
    Abstract: A metal member is manufactured that has a plating layer of precious metal on the surface of a bare metal portion formed of a predetermined metal. First, a surface layer of the bare metal portion is removed. Then, a plating of precious metal is applied to the portion where the surface layer of the bare metal portion was removed. Then, the metal member is heat treated in an inert atmosphere. As a result, a metal member can be manufactured that has less carbide and hydrogen near a boundary surface of the plating layer and the bare metal portion than it would if the removing step and the heat treating step were not performed. With a metal member manufactured in this way, the plating layer does not easily peel away.

  • Patent number: 7989086
    Abstract: A multi-layer seal arrangement includes a dissolution barrier between a braze alloy and a ceramic component. The inventive seal is useful for joining a ceramic component to another ceramic component or a metal component, for example. In one example, the braze comprises a gold alloy and the dissolution barrier comprises a layer of alumina on the order of 2-3 microns thick. A titanium wetting layer is provided between the alumina layer and the alloy. A metallization layer provided between the dissolution barrier and the ceramic component in one example comprises a layer of gold between two thin layers of titanium. In one particular example, a platinum mesh is included with the gold of the braze alloy to control braze flow during the brazing operation.

  • Patent number: 7985487
    Abstract: Disclosed is a corrosion resistant conductive part, which is made by forming a thin plated gold layer of thickness 100 nm or less on a stainless steel sheet, and for which high corrosion resistance is guaranteed even with a very thin gold layer. The part is characterized in that the maximum value “v” of atomic concentration of gold given by Auger analysis is at least 98% of the total atomic concentrations of all the elements, which is deemed to be 100%, in the thin gold layer ranging from the surface to the interface of the gold layer and the metal substrate, at which the descending curve of gold crosses the ascending curve of the most predominant component of the substrate metal.

  • Publication number: 20110132655
    Abstract: An electronic component device having a first sealing frame formed on a main substrate and a second sealing frame formed on a cover substrate, both of which are composed of a Ni film. A bonding section bonds the first sealing frame to the second sealing frame. For example, a Bi layer is formed on the first sealing frame and an Au layer is formed on the second sealing frame, and then the first sealing frame and the second sealing frame are heated at a temperature of 300° C. for 10 seconds while applying pressure in the direction in which the first sealing frame and the second sealing frame are close contact with each other to form the bonding section. The bonding section is constituted by a mixed layer predominantly composed of a mixed alloy of a Ni—Bi—Au ternary alloy and Au2Bi.
