Abstract: Disclosed herein are methods of producing a gas at a controlled rate, the methods comprising directing air through a layered bed to produce a gas. The layered bed comprises alternating layers of a layer of dry particles comprising a precursor and a layer of dry particles comprising a proton-generating species. The gas is produced at a rate that is controlled by controlling the presence or absence of air flowing though the layered bed, the amount of time the air flows through the layered bed, the total number of layers in the layered bed, the average thickness of each of the layers of dry particles comprising the precursor in the layered bed, the average thickness of each of the layers of dry particles comprising the proton-generating species in the layered bed, the temperature the method is performed at, or a combination thereof.

Abstract: Disclosed herein are methods of producing a gas at a variable rate, the methods comprising dynamically mixing dry particles comprising a precursor and dry particles comprising a proton-generating species to produce a gas and wherein the gas is produced at a rate that is varied by varying the amount of time the dry particles comprising the precursor and the dry particles comprising the proton-generating species are dynamically mixed, the rate at which the dry particles comprising the precursor and the dry particles comprising the proton-generating species are dynamically mixed, or a combination thereof.

Abstract: A self-contained generator/fumigator and delivery system is described herein that provides for sealed containment to store, isolate and protect two or more solid and/or liquid reactants in separate chambers. Upon activation, the container facilitates robust mixing of the reactants, the containment thereof and allows the release of a pre-determined amount of gaseous products, e.g., chlorine dioxide, carbon dioxide and others, into a targeted volume of water, air or other solution.

Abstract: The invention is a method and composition for producing carbon dioxide that is based on the reaction or activation of at least one carbon-containing compound with protons. The carbon-containing compound can be in the form of a powder, an impregnated carrier (e.g. zeolite crystals) or an aqueous solution and is preferably selected from the group consisting of carbonates, bicarbonates or sesquicarbonates. The protons are preferably provided by a proton-generating species such as an acid or metal salt. The method and composition can further include a water-retaining substance and/or a chlorine dioxide-producing compound in accordance with the invention.

Abstract: The invention is a method for attracting mosquitoes by producing a volatilized acid by combining an acid precursor with water to produce the humidified vapor acid attractant, preferably hydrogen chloride. The humidified volatilized acid can be further combined with carbon dioxide, or carbon dioxide can be simultaneously produced to attract mosquitoes. The acid precursor can be a hydrate of ferric chloride, such as ferric chloride hexahydrate. The acid precursor can be impregnated in a carrier, and can be combined with water through exposure to water vapor in the atmosphere, the intentional addition of water, or water produced by a chemical reaction.

Abstract: The present invention is a method and apparatus that uses microwave energy to produce highly active forms of oxidizing compounds that react with nitric oxide and other lower valence components in gaseous streams to form compounds that can be readily removed by conventional pollution abatement processes. An oxidation chamber is used to simultaneously expose the oxidizing compound to microwave energy and contact it with the gaseous stream. The present invention provides a reliable, cost effective means of oxidizing pollutants into forms that can be effectively removed using existing pollution abatement devices.
