Abstract: Described are processes and equipment that are useful to remove hydrogen peroxide from a gas, for example from a hospital room as a step of sterilizing the room using hydrogen peroxide, or from a flow of exhaust air that is produced by sterilization equipment that uses hydrogen peroxide as a sterilizing agent.

Abstract: An air filtration system includes a photocatalytic reactor and a first air filter upstream of the photocatalytic reactor. The photocatalytic reactor includes a photocatalyst composition and a lamp configured to irradiate the photocatalyst composition. The photocatalyst composition is configured to decompose one or more volatile organic compounds in the air. The first air filter configured to filter one or more deactivating compounds from the air. A method of filtering air in an air filtration system includes passing air through a photocatalytic reactor and passing the air through a first filter prior to the passing of the air through the photocatalytic reactor. The passing of the air through the photocatalytic reactor includes a photocatalyst composition decomposing one or more volatile organic compounds in the air.

Abstract: Provided are certain activated carbonaceous materials which have been treated with dilute mineral acids to modify their surface chemistry and morphology. The modified activated carbonaceous materials of the disclosure are useful in removing certain contaminants from gaseous streams. In one embodiment, the contaminants are compounds containing silicon and oxygen moieties, such as alkyl silanols and alkyl siloxanes. The modified activated carbonaceous materials can be incorporated into filters and filter systems.

Abstract: A method of manufacturing an article is provided. The method includes applying a coating onto a fabric layer, wherein the coating absorbs solar energy and converts solar energy into electrical energy. Moreover, the method includes applying a membrane onto the fabric layer. An insulation layer is applied onto the membrane. Further, a heat conductive coating is applied onto at least one of the membrane and the insulation layer.

Abstract: A system, in certain embodiments, includes a protective membrane having first and second layers. The first layer is air permeable, vapor breathable, and liquid repellant. The second layer is vapor breathable, liquid repellant, and adsorptive of chemical and/or biological agents.
