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 method for enhanced validation of an entity associated with a COF token includes: storing at least transaction data, a token requester identifier (TRJD), and a COF token identifier; receiving payment credentials, wherein the payment credentials include at least a COF-specific payment token; generating a transaction message, wherein the transaction message is formatted based on one or more standards and includes at least a plurality of data elements including at least a first data element configured to store the COF-specific payment token, a second data element configured to store the COF token identifier, a third data element configured to store the TRID, and one or more additional data elements configured to store the transaction data; and electronically transmitting the generated transaction message to a financial institution via a payment network.

A controlled portable combustion composition, comprising a carrier, where the carrier functions as a binder and as a fuel for combustion, an oxidizer, and, an auxiliary agent, where the auxiliary agent is a transitional substance and a flame retardant which renders the composition flameless; and where substantially all of the carrier, the oxidizer, and the auxiliary agent are converted to smoke at the end of said combustion.

A method of forming polymer composites includes mixing a transition metal oxide precursor including at least one transition metal, a polymer as a binder, a solvent for the polymer, and water to form a first solution including polymer-transition metal complexes. The polymer-transition metal complexes are hydrolyzed to produce a plurality of transition metal oxide nanoparticles, wherein water is added in the mixing in a stoichiometric excess for the hydrolyzing. The solvent and residual of the water remaining after the hydrolyzing are removed. A polymer composite including the transition metal oxide nanoparticles dispersed in the polymer results after the removing, where some of the polymer is chemically conjugated to a surface of the transition metal oxide nanoparticles.

A method can include forming a mixture of an explosive and a thermally conductive material; disposing at least a portion of the mixture in a chamber of a capsule; and at least partially sealing the chamber.

Explosive compositions for use in high temperature, reactive ground, or both, are disclosed. The explosive compositions can include an emulsion with a continuous organic fuel phase and a discontinuous oxidizer phase. The oxidizer phase can include one or more Group I or Group II nitrates.

An explosive sheet simulant that uses an ethylene vinyl acetate polymer combined with either a mixture of a boron carbide and iron oxide for X-ray attenuating properties or calcium carbonate for millimeter wave properties, wherein the components of the mixture are selected such that the sheet has a predetermined flexural modulus combined with particle density, effective atomic number, x-ray transmission properties, or millimeter wave properties.
