This invention relates to a thermal hydrogen generator and a process and system for generating hydrogen gas, more specifically to a process and system for generating hydrogen gas by thermally decomposing a metal hydride.

An explosive composition for use in telescopically expanding non-lethal training ammunition comprises tetrazene and paraffin wax. The explosive composition can be used as a primer and/or as a source of energetic material in a telescopically expanding non-lethal training cartridge; it can be used to propel a projectile from a telescopically expanding non-lethal training cartridge; and/or it can be used to expand telescopically a non-lethal training cartridge within a host gun.

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.

A discrete gradient charge that has a discrete first hollow cylindrical layer of a solid first fuel, which is about 85% by weight fine aluminum powder having a median diameter of about 3.5 microns. There is a discrete second hollow cylindrical layer of a solid second fuel that is about 80% by weight coarse aluminum powder with a median diameter of about 31.0 microns. The fuels have a cured HTPB binder. A pellet of an explosive positioned within the first hollow cylindrical layer provides ignition. The fuel in the charge reacts with the surrounding air or with a hollow cylindrical oxidizer layer, or a combination thereof.
