An antimicrobial barrier is created by incorporation of CuQ nanoparticles of an appropriate size and at a concentration necessary and sufficient to create a unique bioelectrical environment. The unique bioelectrical environment results in biocidal effectiveness through a multi-factorial mechanism comprising a combination of the intrinsic quantum flux of copper (Cu0, Cu1+, Cu2+) ions and the high surface-to-volume electron sink facilitated by the nanoparticle. The result is the constant quantum flux of copper which manifests and establishes the antimicrobial environment preventing or inhibiting the growth of bacteria.

  • Patent number: 9034073
    Abstract: A method for making a metal-based nano-composite material is disclosed. In the method, a semi-solid state metal-based material is provided. The semi-solid state metal-based material is stirred and nano-sized reinforcements are added into the semi-solid state metal-based material to obtain a semi-solid state mixture. The semi-solid state mixture is heated to a temperature above a liquidus temperature of the metal-based material, to achieve a liquid-metal-nano-sized reinforcement mixture. The liquid-metal-nano-sized reinforcement mixture is ultrasonically processed at a temperature above the liquidus temperature by conducting ultrasonic vibrations to the liquid-metal-nano-sized reinforcement mixture along different directions at the same time.

  • Patent number: 9023457
    Abstract: Described herein are various methods for making textured articles, textured articles that have improved fingerprint resistance, and methods of using the textured articles. The methods generally make use of masks comprising nanostructured metal-containing features to produce textured surfaces that also comprise nanostructured features. These nanostructured features in the textured surfaces can render the surfaces hydrophobic and oleophobic, thereby beneficially providing the articles with improved fingerprint resistance relative to similar or identical articles that lack the texturing.
