  • Patent number: 10036833
    Abstract: A superhydrophilic coating on a substrate can be antireflective and antifogging. The coating can remain antireflective and antifogging for extended periods. The coating can include oppositely charge inorganic nanoparticles, and can be substantially free of an organic polymer. The coating can be made mechanically robust by a hydrothermal calcination.

  • Publication number: 20180002550
    Abstract: A simple spray coating process can be utilized to create epoxy/HNT nanocomposites with vertically aligned nanotubes. Important mechanical properties such as modulus and hardness values can be optimized and enhanced by controlling the level of nanotube dispersion during processing and the final orientation of the nanotubes. Thus, a technologically relevant processing scheme can be used to fabricate HNT nanocomposites with a high level of control over nanotube alignment and the resulting mechanical properties.

  • Publication number: 20170266317
    Abstract: Uniform, functional polymer patches can be attached to a fraction of the surface area of living individual cells. These surface-modified cells can cross the blood-brain barrier while remaining viable after attachment of the functional patch. Functional payloads carried by the patch can include a drug. The patch can include one or more polyelectrolyte multilayers (PEMs).

  • Publication number: 20150315562
    Abstract: Uniform, functional polymer patches can be attached to a fraction of the surface area of living individual cells. These surface-modified cells remain viable after attachment of the functional patch. The patch does not completely occlude the cellular surface from the surrounding environment. Functional payloads carried by the patch may include, for example, drugs or other small molecules, peptides, proteins, thermally responsive polymers, and nanoparticles, or any other material that can be incorporated in a polymer patch of subcellular dimensions. The patch can include one or more polyelectrolyte multilayers (PEMs).

  • Publication number: 20140336039
    Abstract: Titania-based porous nanoparticle coatings are mechanically robust, with low haze, which exhibit short time scales for decomposition of fingerprint oils under ultraviolet light. The mechanism by which a typical dactylogram is consumed combines wicking of the sebum into the nanoporous titania structure followed by photocatalytic degradation. These TiO2 nanostructured surfaces are also anti-fogging, anti-bacterial, and compatible with flexible glass substrates and remain photocatalytically active in natural sunlight.

  • Patent number: 8701927
    Abstract: A superhydrophilic thin film is formed on a metal surface of a boiler vessel to alter the wettability and roughness of the surface, which, in turn, changes the boiling behavior at the surface. The superhydrophilic film is formed by depositing a layer of a first ionic species on the surface from a solution. A second ionic species having a charge opposite to the that of the first ionic species is then deposited from solution onto the surface to produce a bilayer of the first ionic species and the oppositely charged second ionic species. The depositions are then repeated to form a plurality of bilayers, on top of the preceding bilayer. The bilayers are then heated, leaving the second ionic species on the metal surface to form a superhydrophilic film.
