Abstract: Methods of making unique water treatment compositions are provided. In one embodiment, a method of making a doped metal oxide or hydroxide for treating water comprises: disposing a metal precursor solution and a dopant precursor solution in a reaction vessel comprising water to form a slurry; and precipitating the doped metal oxide or hydroxide from the slurry.

Abstract: A water treatment composition includes an oxidizing component and an adsorbing component, wherein one or both of the oxidizing component and adsorbing component comprise nanostructured materials. The water treatment compositions are useful in at least partially removing contaminants such as metallic or cationic arsenic, lead, chromium, and/or mercury from water.

Abstract: Methods for the production of monometal carbides are disclosed. A metal source and a carbon source are reacted under conditions suitable to produce a reaction product. The reaction product may comprise fully carburized monometal carbide and excess carbon, or an intermediate product comprising partially carburized monometal carbide in the presence or absence of excess carbon. The carbon content in the reaction product may then be adjusted in a controlled removal or addition process to produce a product the fully carburized monometal carbide having near stoichiometric carbon.

Abstract: Anti-fouling coating compositions and methods of making and using those compositions are provided. In an embodiment, a coating composition comprises ceramic nanoparticles, wherein the coating composition is capable of inhibiting contaminants from adhering to a solid surface.

Abstract: Cored wires having a core comprising agglomerates of superfine particles and/or nanoparticles for thermal spray or overlay weld applications and methods of making the same are provided. Methods of coating a substrate by thermal spraying such as electric arc spraying with such cored wires are also provided. In an embodiment, a cored wire comprises a metallic sheath at least partially surrounding a core comprising agglomerates of superfine particles, nanoparticles, or a combination comprising at least one of the foregoing particles.

Abstract: An antimicrobial composite is provided, comprising a catalyst capable of promoting oxidation of organic molecules incorporated in a carrier, for example a hydrophilic or water-based material, the catalyst configured such that it will not discolor surrounding material under the influence of oxidative conditions

Abstract: A water treatment composition includes an oxidizing component and an absorbing component, wherein one or both of the oxidizing component and absorbing component comprise nanostructured materials. The water treatment compositions are useful in at least partially removing contaminants such as metallic or cationic arsenic, lead, chromium, and/or mercury from water.
