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 precursor formulation of an energetic composition with improved electrostatic charge dissipation, including an amorphous carbon black having a specific surface area of at least about 1,200 m.sup.2/g, in an amount from about 0.05% by weight to about 0.25% by weight. Also disclosed is a precursor formulation of a propellant composition with improved electrostatic charge dissipation. The amorphous carbon black having a specific surface area of at least about 1,200 m.sup.2/g may enhance electrostatic charge dissipation of the HTPB-based propellant composition, without affecting a breakdown voltage of the propellant composition.
