Energetic properties of new nanothermites based on in situ MgWO4-rGO, CoWO4-rGO and Bi2WO6-rGO

We report the synthesis of Zn(C6H4N5)N3, a new three-dimensional metal-organic framework (MOF) that exhibits strong energetic properties with high thermostability. The compound is synthesized by the hydrothermal method with in situ ligand formation under controlled pH. Structural characterization is carried out by single-crystal XRD, elemental analysis and FTIR. Energetic properties are obtained from TGA and DSC measurements. This novel MOF structure is thermally stable up to 345 C and its heat of detonation is -400$ kJ/g. The measured velocity and pressure of detonation are 4.66 km/s and 9.99 GPa, respectively.

Saturn's Rings

ABSTRACTA mission to rendezvous with the rings of Saturn is studied with regard to science rationale and instrumentation and engineering feasibility and design. Future detailedin situexploration of the rings of Saturn will require spacecraft systems with enormous propulsive capability. NASA is currently studying the critical technologies for just such a system, called Nuclear Electric Propulsion (NEP). Electric propulsion is the only technology which can effectively provide the required total impulse for this demanding mission. Furthermore, the power source must be nuclear because the solar energy reaching Saturn is only 1% of that at the Earth. An important aspect of this mission is the ability of the low thrust propulsion system to continuously boost the spacecraft above the ring plane as it spirals in toward Saturn, thus enabling scientific measurements of ring particles from only a few kilometers.
