Abstract: A composition for energy-controlled generation and release of at least one gas, which includes an energy-activated catalyst capable of being activated by electromagnetic energy, and a solid or a liquid containing anions capable of being oxidized by the activated catalyst or reacted with species generated during activation of the catalyst to generate at least one gas. The composition, when exposed to electromagnetic energy, is capable of generating and releasing the gas after activation of the catalyst and oxidation or reaction of the anions.

Abstract: A polymeric body covering article that generates and releases gas upon activation by electromagnetic energy and/or moisture. The gas provides antimicrobial and/or antiodor protection to objects in contact or in proximity to the interior surface of the article and/or to objects in contact or in proximity to the exterior surface of the article.

Abstract: A liner for placement in a container holding perishable food products to inhibit decay. The liner is a generally flat mat having a plurality of compartments containing two substances which generate antimicrobial gases. The liner has holes in the mat to facilitate drainage of liquid water past the liner for removal from the container.

Abstract: A particle including anions dispersed throughout an amorohous, paracrystalline or crystalline solid solution, the anions being capable of reacting with hydronioum ions to generated a gas. The particle can be incorporated into a power capable of generating and releasing a gas after hydrolysis of an acid releasing agent.

Abstract: A particle including anions dispersed throughout an amorphous, paracrystalline or crystalline solid solution, the anions being capable of reacting with hydronium ions to generate a gas. The particle can be incorporated into a powder capable of generating and releasing a gas after hydrolysis of an acid releasing agent.

Abstract: Method for reducing normal concentrations of hydrogen cyanide and/or nitrogen oxide by-products in cigarette smoke, by using, as garniture feed for a cigarette filter rod-making apparatus, one or more substrates, one or more surfaces thereof being treated by applying thereto an effective amount of at least one of(A) a solution, emulsion or dispersion of at least one of sodium bicarbonate, sodium carbonate, potassium permanganate, manganese dioxide in a nonionic spin solution;(B) glycerol triacetate;and corresponding filter element and cigarette utilizing a filter formed of such substrate(s).
