The present invention relates to metal oxide nanoparticles, a method for their production, a coating, or printing composition, comprising the metal oxide nanoparticles and the use of the composition for coating of surface relief micro- and nanostructures (e.g. holograms), manufacturing of optical waveguides, solar panels, light outcoupling layers for display and lighting devices and anti-reflection coatings. Holograms are bright and visible from any angle, when coated, or printed with the composition, comprising the metal oxide nanoparticles.

Particle removal systems and methods are provided. The systems and methods utilize flexible wires to collect solid particles and remove them from a carrier liquid in which they are suspended. The solid particles, the wires, or both the solid particles and the wires are coated by a liquid. As the carrier liquid containing the particles passes through the particle removal system, the liquid coatings on the solid particles and/or the flexible wires selectively adhere the solid particles to the flexible wires.

Disclosed is an infill for an artificial turf field, the infill comprising: from about 40 wt. % to about 60 wt. % of a polyvinyl chloride resin; from about 5 wt. % to about 30 wt. % of a plasticizer derived from a naturally occurring source; from about 2 wt. % to about 10 wt. % of a reflective pigment; from about 0.01 wt. % to about 0.1 wt. % of a blowing agent; and from about 5 wt. % to about 30 wt. % of a filler. The infill is pelletized and maintains the temperature of an artificial turf field, when disposed throughout the artificial turf field, at a temperature about 15° F. to about 25° F. less than a temperature of a comparative artificial turf under substantially similar ambient and environmental conditions, wherein a comparative infill of the comparative artificial turf consists essentially of crumbed rubber infill.

An actinic radiation-curable inkjet ink contains an actinic radiation-polymerizable compound, surface-treated titanium oxide, and a wax. The surface-treated titanium oxide contains carbon atoms in an amount of 0.31 mass % to 2.0 mass % based on the total mass thereof.

The present invention relates to a pigment for a black electrophoretic display having high electrical insulation and excellent dispersibility in the visible region. An objective of the present invention is to provide black titanium dioxide as a pigment for an electrophoretic display. In addition, another objective of the present invention is to provide an ink composition for an electrophoretic display comprising a black titanium dioxide pigment, and an electrophoretic display.

The present invention is a composition comprising an aqueous dispersion of metal oxide pigment particles coated with an organosilane polymer comprising structural units of an alkyltrihydroxysilane or a salt thereof, a dialkyldihydroxysilane or a salt thereof, and an ancillary alkylsilane triol. The composition of the present invention provides hydrophobicity to pigment particles, thereby imparting water resistance, and allows for high loadings of pigment in water without increased viscosity. The dispersion is further useful for providing stain and corrosion resistance in coatings arising from paints.
