摘要： A touch screen display that includes a touch screen user interface having a plurality of layers that includes a top surface layer. The display includes a coating composition coating the top surface layer. The coating composition includes metal-modified cerium oxide nanoparticles (mCNPs) having a predominantly 3+ cerium surface charge and in a range of about 3-30 nm in size and in an amount that is in a range of about 1 weight percentage of a mixture having a binder and the mCNPs and m is an antimicrobial promoting metal that is non-ionizing. The touch screen display is incorporated into various machines or electronic devices. The coating composition forms a self-disinfecting surface that is optically transparent.

摘要： In view of the problem with the prior art, the present invention addresses the following problems: providing a method that can suppress the generation of fine silver particles in a silver nanowire dispersion better than prior methods; and inhibiting, by a convenient method, particulation of silver nanowires on the anode side. A solution is a silver nanowire dispersion that contains silver nanowires, a dispersion solvent, and a chelating agent with the average diameter of the silver nanowires being not more than 100 nm, the silver nanowire dispersion being characterized in that the chelating agent content is 0.1 to 1,000 μmol/g with reference to the silver nanowire content, and the chelating agent is a prescribed aromatic heterocyclic compound having at least one imine skeleton in the molecule.

摘要： A coating for vehicle components, such as frame assemblies and cradle assemblies formed of steel, is provided. The coating includes a first layer including a high phosphate composition applied to the substrate, and a second layer including wax applied to the first layer. For example, the first layer can include a first inorganic acid, an inorganic salt, a second inorganic acid, nickel salt, and ammonium bifluoride; and the second layer can include petroleum, carbon black pigment, and a corrosion inhibitor, the corrosion inhibitor including magnesium. The coating has been found to improve corrosion resistance when applied to steel substrates, compared to wax coatings which are currently applied to steel substrates.

摘要： A coating composition, a method for manufacturing a substrate using the same, and an optical device are provided. The method for manufacturing the substrate provides the substrate having excellent performance, as the substrate has fixed spacers on its surface by using a single layer in which nanoparticles and spacers are dispersed in an alignment film to reduce processes and cost. The optical device may be manufactured by such method.
