Abstract: The present invention provides improved sorbents and corresponding device(s) and uses thereof for the capture of contaminants from breathable air in an enclosed habitable space. The sorbents are capable of rapid and high adsorption of moisture, carbon dioxide and other contaminants from forced air and provide quantitative release of the sorbates when exposed to vacuum. The sorbents may be included in air treatment systems, such as portable life support systems (trace contaminant control systems), to maintain a breathable atmosphere in spacecraft, watercraft, or landcraft having enclosed habitable spaces and also in space suits.

Abstract: The present invention provides an improved sorbent and corresponding device(s) and uses thereof for the capture and stabilization of volatile organic compounds (VOC) or semi-volatile organic compounds (SVOC) from a gaseous atmosphere. The sorbent is capable of rapid and high uptake of one or more compounds and provides quantitative release (recovery) of the compound(s) when exposed to elevated temperature and/or organic solvent. Uses of particular improved grades of mesoporous silica are disclosed.

Abstract: A method and system of extracting iron oxide from ore is provided, which may include adding a chelating agent to an iron ore to form an iron ore and chelating agent solution, heating the solution to reflux in water, and filtering the solution to yield an extraction residue and a chelated iron solution. The chelated iron solution may be treated with a potassium hydroxide and water solution to yield iron hydroxide.

Abstract: A training aid for use in training canines to detect an explosive material includes an explosive material adsorbed in the pores of a high surface area mesoporous or nanoporous host material. By adjusting the surfaces of the pores of the substrate material, the substrate can accommodate various types of explosive materials in a non-detonable and non-flammable manner, including nitroaromatics, nitroamines, nitrate-based explosives, and peroxide-based explosives. When the training aid is in an unsealed condition, a continuous flux of explosive material is released without providing any explosive or flame hazard to the trainer and canine.

Abstract: A passive wireless corrosion sensor is disclosed. A circuit is configured to provide a signal response when energized. An antenna is configured to wirelessly receive energy for energizing the circuit and to receive the signal response from the circuit and transmit the signal response. A corrosion sensitive connector interposes the circuit and the antenna. The corrosion sensitive connector conducts the energy from the antenna to the circuit and conducts the signal response from the circuit to the antenna when in a substantially non-corroded state. The corrosion sensitive connector creates an effectively non conducting link between the antenna and the circuit when in a substantially corroded state.
