Abstract: Atomic hydrogen, for use as a fuel or as an explosive, is stored in the presence of a strong magnetic field in exfoliated layered compounds such as molybdenum disulfide or an elemental layer material such as graphite. The compound is maintained at liquid helium temperatures and the atomic hydrogen is collected on the surfaces of the layered compound which are exposed during delamination (exfoliation). The strong magnetic field and the low temperature combine to prevent the atoms of hydrogen from recombining to form molecules.

Abstract: A liquid mixture of tetrafluorammonium bifluoride in anhydrous liquid hydrogen fluoride in the liquid and/or gaseous decomposed state serves as an oxidizer for fuels. Tetrafluorammonium bifluoride is present in the liquid in an amount up to about 50 mole percent.
Abstract: A method for increasing the flow of earth strata contained fluid, such as natural gas and oil, to a well shaft from surrounding rock formations by explosive fracturing said rock formations with the substantial elimination of the formation of water in the resulting rock fractures and rock formation adjacent to the fractures.

Abstract: A fuel for rocket motors is provided in the form of a slurry of particulate metal or metalloid particles having a particle size of about 0.1 to 10 microns suspended in an alcohol having from 1 to 3 carbon atoms in the presence of a non-thixotropic amount of high viscosity grade hydroxypropyl cellulose.
Abstract: 1. A storable oxidizing composition consisting essentially of a solution of trifluoramine oxide and chlorine pentafluoride, which contains up to 25 mole % of trifluoramine oxide in liquid phase at 24.degree. C.
Abstract: Chlorine trifluoride dioxide is disclosed for use as an oxidizer in formulating energetic compositions, such as propellants. The stable ClF.sub.3 O.sub.2 is produced by reacting a ClO.sub.2 F.sub.2 .sup.+ salt with a strong Lewis base at -78.degree. C.
Abstract: An aerially delivered fuel-air munition consisting of an impermeable tank filled with a pressurized liquid fuel and joined at its two opposite ends with a nose section and a tail assembly respectively to complete an aerodynamic shape. On impact the tank is explosively ruptured to permit dispersal of the fuel in the form of a fuel-air cloud which is detonated after a preselected time delay by means of high explosive initiators ejected from the tail assembly. The primary component in the fuel is methylacetylene, propadiene, or mixtures thereof to which is added a small mole fraction of a relatively high vapor pressure liquid diluent or a dissolved gas diluent having a low solubility in the primary component.
