A method of colorizing stainless steel strip involves the continuous surface treatment of stainless steel strip with aqueous suspensions of rare earth oxide nano or micro particles or aqueous rare earth nitrate solutions of nano or micro particles. The surface treatment can be applied by roll coating, spraying or other conventional application techniques. The coated strip is then continuously annealed. The surface treatment can provide a variety of colors. It also improves corrosion resistance of the processed stainless steel strip. Steel strip treated in this manner is suitable for a variety of applications in the building systems, automotive and appliance markets.

An electrode for gas evolution in electrolytic processes having a metal substrate and a coating formed on the substrate, the coating having at least a catalytic porous outer layer containing regions of porous nickel oxide dispersed within a solid nickel oxide binder, and a method for the production of the electrode from preformed nickel vanadium oxide particles.

Methods are provided for selectively depositing a material on a first surface of a substrate relative to a second, different surface of the substrate. The selectively deposited material can be, for example, a metal, metal oxide, or dielectric material.

The invention relates to a method for producing a glass coating on a substrate, comprising the following steps: applying a liquid sol to at least one surface of the substrate, allowing the sol to react to form a gel, and briefly treating the gel on the at least one surface outside a furnace in the presence of water vapour at a temperature of at least 700 C. The method according to the invention makes the coated surface dirt-repellent, electrically insulating, non-combustible, easy to clean and resistant to ageing, corrosion and chemicals. A particular advantage of the method according to the invention is that it can be carried out outside a furnace and nevertheless makes glass coatings possible.

A process of forming a mixed metal oxide solid is provided. The process includes the steps of obtaining a precursor composition comprising at least two metal or metalloid-containing compounds, the metal or metalloid of the at least two compounds being different, one from the other; and allowing the at least two metal or metalloid-containing compounds of the precursor composition to at least partially react by hydrolysis and/or condensation. The at least two metal or metalloid-containing compounds may have different points of zero charge (PZC). Further material or articles comprising a substrate or material coated with or otherwise in physical connection to the mixed metal oxide solid formed according to the process are also provided.

A corrosion-resistant coating on an aluminum-containing substrate such as an aluminum substrate, an aluminum alloy substrate (e.g., AA 2024, AA 6061, or AA7075), or other aluminum-containing substrate includes a corrosion inhibitor-incorporated ZnAl layered double hydroxide (LDH) layer and a sol-gel layer. A zinc salt and a corrosion inhibitor (e.g., a salt of an oxyanion of a transition metal such as a vanadate) is dissolved to form a zinc-corrosion inhibitor solution, and the substrate is immersed in or otherwise contacted with the solution to form the corrosion inhibitor-incorporated ZnAl LDH layer on the substrate. A sol-gel composition is applied on the corrosion inhibitor-incorporated ZnAl LDH layer of the substrate to form a sol-gel layer, and the sol-gel layer is cured.

The present invention generally relates to a method for forming a light extraction layer comprising nanostructures, the method comprising: providing a substrate, the substrate being at least partially transparent to UV light; forming a non-aqueous precursor solution comprising fluorine and an alkaline earth metal to form alkaline earth metal difluoride particles; applying the precursor solution on at least a first side of the substrate; drying the substrate at a first temperature for a first period of time; and baking the substrate at a second temperature, higher than the first temperature, for a second period of time, thereby forming a light extraction nanostructure layer comprising alkaline earth metal difluoride nanostructures on the substrate. The present invention also relates to a light extraction structure and to a UV lamp comprising such an extraction structure.

A coating composition including an inorganic sol material and an organic colorant is applied to mineral particles and cured at a temperature less than 200 degrees Celsius provides roofing granules with improved luster.

Coated articles are described herein that include a surface-modifying layer that is fluorine-free. In aspects, the surface-modifying layer comprises a partial silica-like network having a ratio of SiOSi bonds to Si atoms in the anti-fingerprint coating from about 2 to about 3. Additionally or alternatively, the surface-modifying layer further comprises an alkyl silane at the exterior surface and bonded to a SiO group in the silica-like network. Methods include evaporating a functionalized polyhedral oligomeric silsesquioxane onto a first major surface. Methods include impinging an ion beam on the first major surface. Alternatively, methods include disposing and heating a solution comprising a polysilazane or a polyhedral oligomeric silsesquioxane on a first major surface. In aspects, methods include reacting material at the first major surface with a alkyl silane.
