Abstract: The present invention provides a metal/metal oxide doped-WO3 flower-like assemblies as a photocatalyst applied to photocatalytic inactivation of influenza virus and bacteria under UV or visible light activation, and further provides a surface-modulator-driven synthesis method for producing WO3 flower-like assemblies, as well as doping methods for doping the metal/metal oxide to the WO3 flower-like assemblies. The metal/metal oxide doped in WO3 flower-like assemblies can further enhance the antiviral and antibacterial performances.

Abstract: A plasma driven catalyst apparatus useful for disinfecting and purifying air. The apparatus has a synergistically favorable effect from plasma and catalyst on high disinfecting and purifying efficiency and efficacy, low by-product formation, and low energy consumption. The plasma combined with catalyst enhances the production of new reactive species, increases the oxidizing power of the plasma discharge, as well as activate the catalyst that additionally contributes towards the disinfection and purification process and the elimination of toxic by-products.

Abstract: An anti-tarnish composition including a polymer resin; a photoinitiator; a coating thickness adjusting agent; and optionally a dye useful for protecting metal substrates from tarnishing and methods of applying the anti-tarnish composition to metal substrates using an electroplating method. The anti-tarnish composition can be selectively applied to the metal surfaces of jewelry containing gemstones.

Abstract: The present invention provides photopolymer compositions for 3D printing which have low viscosity, proper curing rate, low volume shrinkage, and low ash content. Such compositions may be used in 3D printing for direct investment casting of products and rapid prototyping.
