Abstract: Employing non-energetic MCPs as hosts (fuel) for the adsorption of oxidant molecules enables the intimate and molecular scale mixing of fuel and oxidizer on a level that is not commonly achievable in traditional energetic mixtures. The adsorption of the oxidants into MOF-5 resulted in increased heat released upon decomposition, which shows potential for utilization of this method as a platform to develop high-performance primary energetic materials.

Abstract: A catalyst for decomposing high-concentration hydrogen peroxide comprises an active layer on a carrier comprising gamma-phase alumina. The carrier can also comprise aluminum, with the gamma-phase alumina forming a passivating layer on the surface of the aluminum. The active layer can comprise platinum. Apparatus for decomposing hydrogen peroxide can include the catalyst in a decomposition chamber arranged to receive hydrogen peroxide. The apparatus can be used as a thruster, comprising a nozzle arranged to generate thrust by directing exhaust gases in a specific direction. For example, the thruster can be a monopropellant, bipropellant, or hybrid thruster. In other embodiments, the apparatus can be used as a gas generator or a fuel cell.

Abstract: The present invention is directed to propellant grains having multiple layers consisting of an outer, slow burning, layer composition and an inner, fast burning, layer with desirable progressivity burn rates. The outer, slow burning, layer comprising a first energetic material, a first plasticizer and a first binder and an inner, fast burning, layer comprising a second energetic material, and the same plasticizer as the outer layer, and a second binder. The compositions in the propellant grain provided herein provides for a burn rate energy differential between the outer, slow burning, layer and inner, fast burning, layer of at least 2.

Abstract: The present invention is directed to an explosive composition comprised of heavy ANFO and expanded polymeric beads that have a density that is less than the density of the heavy ANFO. The expanded polymeric beads have a size that is determined or based on the size of ammonium nitrate prills used in the heavy ANFO portion of the composition. In one embodiment, the expanded polymeric beads that are utilized in the composition are at least 70% of the lower limit of the mesh size of the predominant ammonium nitrate prill mesh size. In another embodiment, the expanded polymeric beads are at least 70% of a size that is related to the average mesh size of the ammonium nitrate prills.
