    Abstract: A lubricant composition having an enhanced thermal conductivity, up to 80% greater than its conventional analogues, and methods of preparation for these fluids are identified. One preferred composition contains a base oil, nanomaterial, and a dispersing agent or surfactant for the purpose of stabilizing the nanomaterial. One preferred nanomaterial is a high thermal conductivity graphite, exceeding 80W/m-K in thermal conductivity. The graphite is ground, milled, or naturally prepared to obtain a mean particle size less than 500 nm (nanometer) in diameter, and preferably less than 100 nm, and most preferably less than 50 nm. The graphite is dispersed in the fluid by one or more of various methods, including ultrasonication, milling, and chemical dispersion. Carbon nanostructures such as nanotubes, nanofibrils, and nanoparticles are another type of graphitic structure useful in the present invention. Other high thermal conductivity carbon materials are also acceptable. To confer long-term stability, the use of one or more chemical dispersants or surfactants is useful. The thermal conductivity enhancement, compared to the fluid without graphite, is proportional to the amount of nanomaterials added. The graphite nanomaterials contribute to the overall fluid viscosity, partly or completely eliminating the need for viscosity index improvers and providing a very high viscosity index. Particle size and dispersing chemistry is controlled to get the desired combination of viscosity and thermal conductivity increase from the base oil while controlling the amount of temporary viscosity loss in shear fields. The resulting fluids have unique properties due to the high thermal conductivity and high viscosity index of the suspended particles, as well as their small size.

    Abstract: A novel use of nanomaterials as a viscosity modifier and thermal conductivity improver for gear oil and other lubricating oil compositions. The gear oils of the instant invention have a higher viscosity index, higher shear stability, and improved thermal conductivity compared to currently available conventional gear oils. The preferred nanoparticles also impart a reduction in the coefficient of friction, including reduced friction in the boundary lubrication regime. These properties are obtained by replacing part or all of the polymer thickener or viscosity index improver or some other part of the composition normally used in gear oils with nanomaterials of suitable shape, size, and composition.

    Abstract: This invention relates generally to water resistant peelable protective and decorative clear or pigmented foam coating compositions and, more specifically, to aqueous and solvent based, polymeric coating compositions which form a protective and/or decorative coating and is removably adhered to a variety of substrates, including automotive paints, metals, glass, vinyl, plastics, concrete, natural and synthetic elastomers, and ceramics. The coatings present a three-dimensional expandable foamy coating, and can be readily peeled off from the substrate as a whole piece. The coatings may be formulated for temporary or long-term protection depending upon the application. The peelable coatings can be applied as a paint, paste, film, or expandable foam cord whereby the expansion of the foam can be controlled by the formulation and applicator.

    Abstract: An aqueous wheel and/or tire cleaning solution for removing the dirt from the surface of aluminum, chrome, stainless steel, painted steel, painted aluminum, clear coated aluminum, rubber, and plastic wheels and tires without scrubbing by applying the cleaning solution to the wheel and/or tire then rinsing the wheel and/or tire with water. Selected polymers include a polyvinylpyrrolidone, a poly(N-vinylimidazole), a poly(4-vinylpyridine-betaine), and/or a poly(4-vinylpyridine-N-oxide) each one of which can be used with conventional wheel cleaning components such as an acid or alkaline-based cleaning formulation to dramatically improve its cleaning power. These polymers can attach to organic and inorganic dirt particles forming a complex with them for easy removal from the wheel and/or tire during rinsing, leaving the wheel and/or tire clean without scrubbing the wheel or tire surface.
