  • Patent number: 11764506
    Abstract: A connector pair includes a first connector, and a second connector electrically connected to the first connector. The first connector includes a first electrical contact part provided with a graphene film on a metal base material. The second connector includes a second electrical contact part electrically connected to the first connector via the graphene film. A contact area between the first electrical contact part and the second electrical contact part is smaller than an area of the graphene film coating the metal base material.

  • Publication number: 20230257334
    Abstract: [Solution] The present invention relates to a method for partially oxidizing an alkane, including contacting an alkane with a supported catalyst in a presence of an oxidizer to convert the alkane into an aldehyde, wherein the supported catalyst is composed of a bimetallic oxide and a support carrying the bimetallic oxide, and the bimetallic oxide is represented by the following formula and includes oxygen and two metals selected from metals of groups 8 to 10 of the periodic table: AmBnOx wherein the bimetallic oxide and support are each a metal selected from metallic elements of groups 8 to 10 of the periodic table; the bimetallic oxide and support are not the same metallic element; m, n, and x mean amounts ((mmol)) of the bimetallic oxide, the support, and oxygen, respectively, per 1 g of the supported catalyst; m is more than 0 [mmol/g-cat] and less than 1 [mmol/g-cat]; n is more than 0 [mmol/g-cat] and less than 1 [mmol/g-cat]; and x is a value [mmol/g-cat] satisfying oxidation states of the bimetall

  • Patent number: 11411335
    Abstract: An electrical connection component includes a connecting part that is electrically conductive, and an electrical contact on at least a part of a surface of the connecting part, the electrical contact including a graphene oxide film. The graphene oxide film is graphene oxide or a stack of graphene oxide, and a thickness of the graphene oxide film is 1 nm or more and 50 nm or less. The electrical connection component may be either a male terminal or a female terminal.

  • Publication number: 20210135386
    Abstract: The invention relates to a connector including an electrical contact material which contains a metal base material and a conductive coating layer on a surface of the metal base material, in which the conductive coating layer includes: a matrix phase constituted by a metal other than gold; and a second phase that includes: elongated portions that elongate in a depth direction from a surface of the matrix phase; and enlarged diameter portions that, in the surface of the matrix phase, extend from the elongated portions along the surface, in which the second phase is constituted by gold or a non-metal conductive material that is less oxidizable than the metal constituting the matrix phase.
