Abstract: A method for protecting a plant from an arthropod may include applying an amount of a repellant composition including diatomaceous earth to a plant. According to some aspects, the repellent composition may render the plant unpalatable to the arthropod, resulting in death of the arthropod by starvation. A method for protecting a plant from an arthropod may include applying an amount of a repellant composition including diatomaceous earth to a plant. The arthropod may not include an exoskeleton, and the repellent composition may render the plant unpalatable to the arthropod, resulting in death of the arthropod by starvation.

Abstract: Compositions comprising synthetic rock, e.g., aggregate, and methods of producing and using them are provided. The rock, e.g., aggregate, contains CO2 and/or other components of an industrial waste stream. The CO2 may be in the form of divalent cation carbonates, e.g., magnesium and calcium carbonates. Aspects of the invention include contacting a CO2 containing gaseous stream with a water to dissolve CO2, and placing the water under precipitation conditions sufficient to produce a carbonate containing precipitate product, e.g., a divalent cation carbonate.

Abstract: A method for making a photonic structure, including creating a first vapor stream of a first vapor material, the first vapor stream having a first non-uniform flux in at least one direction; and moving a substrate in at least a portion of the vapor stream. In addition, the method includes depositing the first vapor material on a first major surface of said substrate, and forming a first layer and a density gradient in the first layer during deposition. The first layer is disposed on and the density gradient is in a direction perpendicular to the first major surface.

Abstract: A method for making a porous film includes the steps of forming a cermet film and/or a ceramic film by depositing or co-depositing suitable materials on a substrate, and causing metal in the material(s) to reduce and/or to diffuse to the cermet film surface and/or the ceramic film surface to render the porous film.

Abstract: This invention relates to a protected organotin-based catalyst system for polyurethane synthesis that is useful in coatings applications. The catalyst has low activity in the absence of oxygen. When a coating mixture comprising the catalyst is sprayed and/or applied to a substrate as a thin film in air, the catalyst is activated. For solvent-based refinish systems comprising hydroxyl and isocyanate species at high solids levels, the catalyst system therefore provides extended viscosity stability, i.e., pot life.
