  • Nanowire article and processes for making and using same
    Patent number: 9460921
    Abstract: A nanowire article includes a substrate; a plurality of nanowires disposed on the substrate, the nanowires comprising a semiconductor nitride, the semiconductor comprising an element selected from group 3 of the periodic table; and a superlattice layer interposed between the substrate and the plurality of gallium nitride nanowires. A process for producing a nanowire article includes disposing a superlattice layer on a substrate; disposing a first buffer layer on the superlattice layer; contacting the first buffer layer with a precursor; and forming a plurality of nanowires from the precursor on the first buffer layer to form the nanowire article, the nanowires comprising a semiconductor nitride, the semiconductor comprising an element selected from group 3 of the periodic table.

  • Lyotropic liquid crystal nanofiltration membranes
    Patent number: 7604129
    Abstract: The invention provides composite nanofiltration membranes (FIG. 5) with lyotropic liquid crystal (LLC) polymer porous membranes (30) attached to a porous support (20). The LLC membranes are prepared from LLC monomers which form the inverted hexagonal or bicontinuous cubic phase. The arrangement, size, and chemical properties of the pores can be tailored on the molecular level. The composite membrane of the invention is useful for separation processes involving aqueous and nonaqueous solutions as well as gases. Methods for making and using the composite nanofiltration membranes of the inventions are also provided.
