  • Patent number: 11524478
    Abstract: A self-cleaning transparent conductive surface includes a hydrophobic film and a metal nano-web coupled to the hydrophobic film. The metal nano-web imparts conductive properties to the surface of the film and texturing formed by either the hydrophobic film, substrate or metal nano-web create a super-hydrophobic surface. This super-hydrophobic and conductive surface may be created by etching and layering a metal nano-web over the surface of a hydrophobic film or a rigid substrate, the metal grid may the hydrophobic film or substrate may also be etched in a moth's eye pattern. Both the hydrophobic film or substrate and metal nano-web may be coated in a layer of hydrophobic material to further increase the hydrophobic effect.

  • Patent number: 11519175
    Abstract: A self-stressing shape memory alloy (SMA)/fiber reinforced polymer (FRP) composite patch is disclosed that can be used to repair cracked steel members or other civil infrastructures. Prestressed carbon FRP (CFRP) patches have emerged as a promising alternative to traditional methods of repair. However, prestressing these patches typically requires heavy and complex fixtures, which is impractical in many applications. This disclosure describes a new approach in which the prestressing force is applied by restraining the shape memory effect of nickel titanium niobium alloy (NiTiNb) SMA wires. The wires are subsequently embedded in an FRP overlay patch. This method overcomes the practical challenges associated with conventional prestressing.

  • Patent number: 11492291
    Abstract: Glasses with compressive stress profiles that allow higher surface compression and deeper depth of layer (DOL) than is allowable in glasses with stress profiles that follow the complementary error function at a given level of stored tension. In some instances, a buried layer or local maximum of increased compression, which can alter the direction of cracking systems, is present within the depth of layer. Theses compressive stress profiles are achieved by a three step process that includes a first ion exchange step to create compressive stress and depth of layer that follows the complimentary error function, a heat treatment at a temperature below the strain point of the glass to partially relax the stresses in the glass and diffuse larger alkali ions to a greater depth, and a re-ion-exchange at short times to re-establish high compressive stress at the surface.
