  • Patent number: 11178758
    Abstract: A wiring substrate at which a metal wire is formed includes a substrate containing a resin as a main component and an organic substance having a hydroxyl group; and a metal plating layer constituting the metal wire. A formation portion of the metal wire at one surface of the substrate is rougher than a non-formation portion of the metal wire at the one surface of the substrate, and has the organic substance in a state of being embedded in the resin, and a catalyst. The wiring substrate with such a configuration can increase the adhesion of the metal wire to the substrate.

  • Patent number: 11111561
    Abstract: The present disclosure relates to a preparation method and use of a thickness-controllable bismuth nanosheet and its alloy, in order to solve the technical problems that the existing metal catalysts for the conversion of carbon dioxide to formic acid exhibit a low efficiency, a high overpotential, a relatively positive hydrogen evolution potential, and a poor stability. In the present disclosure, a bismuth nanosheet of a single atom layer thickness with a thickness of only 0.7 nm is obtained through an aqueous solution reduction method by using a bismuth salt compound as a raw material, using ethylene glycol ethyl ether as a solvent, and using a highly reductive aqueous solution containing NaBH4, LiBH4 or the like as a reducing agent, under a protection atmosphere of an inert gas.

  • Patent number: 11098242
    Abstract: Polymer coated proppants for hydraulic fracturing of oil and gas wells have an outer layer portion that comprises an organofunctional coupling agent, preferably an organofunctional silane coupling agent. The use of an organofunctional silane coupling agent in the outer layer portion of the proppant coating is preferably chosen to expose functionalities that will be reactive towards similar functionalities of adjacent and similarly coated proppants so that, when introduced downhole, these proppants form interparticle bonds at the temperatures and crack closure pressures found downhole in fractured strata. Such enhanced interparticle bonding helps keep the proppant in the fracture and maintains conductivity with reduced flowback. The invention also helps proppants designed for low temperature well to bond more firmly and allows proppants designed for high temperature wells to bond well even at lower downhole temperatures, thereby extending their useful range.
