摘要： The present disclosure includes compositions and methods for controlling a pest population, such as insects, arachnids, and other arthropods. The compositions herein may include mineral particles and at least one organic pesticide associated with the mineral particles, e.g., adsorbed and/or incorporated into portions of the mineral particles. For example, the composition may be applied to a substrate and/or an area having pests, such that the composition attaches to a pest proximate the substrate or in the area to deliver the organic pesticide(s) to the pest.

摘要： Materials comprising minerals having modified surface properties, related methods, and their use in products. Materials for use in products may comprise a mineral and a carbonate, such as a precipitated calcium carbonate. Decorating the mineral with the precipitated calcium carbonate may modify a surface property of the mineral, such as, for example, absorptivity, reactivity, or fluorescence.

摘要： The present disclosure includes compositions and methods for filtering a liquid, e.g., water. The compositions herein may include a filter aid comprising a filter medium and packaging having at least one water-soluble portion. When the filter aid is introduced into the liquid to be filtered, the water-soluble portion(s) may dissolve or otherwise degrade in order to expose the filter medium to the liquid.

摘要： A method may be used for reducing titanium dioxide in a composition for forming decorative paper for use in laminated products. The method may include providing a pigment composition including titanium dioxide, and combining the pigment composition with a titanium dioxide extender including at least two particulate minerals to form a combined pigment composition. The titanium dioxide extender may include diatomaceous earth and at least one of aluminosilicate and talc. Combining the pigment composition with the titanium dioxide extender may result in reducing the titanium dioxide by at least 10% while substantially maintaining at least one of whiteness, wet whiteness, brightness, wet brightness, opacity, wet opacity, and resin impregnation of the decorative paper produced including the titanium dioxide extender relative to the decorative paper produced with the titanium dioxide but without the titanium dioxide extender.
