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

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.
