Trace Detection of RDX, HMX and PETN Explosives Using a Fluorescence Spot Sensor
1,3,5-trinitroperhydro-1,3,5-triazine (RDX), octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), and pentaerythritol tetranitrate (PETN), the major components in plastic explosives, pose a significant threat to public safety. A quick, sensitive, and low-cost detection method for these non-volatile explosives is eagerly demanded. Here we present a fluo-spot approach, which can be employed fo...
متن کاملAnisotropic Constitutive Relationships in Energetic Materials: Petn and Hmx
This paper presents results of first-principles density functional calculations of the equation of state (EOS) of PETN-I and P-HMX. The isotropic EOS for hydrostatic compression has been extended to include uniaxial compressions in the [100], [010], [001], [110], [101], [Oil], and [111] directions up to compression ratio VAAQ = 0.70. Equilibrium properties, including lattice parameters and elas...
متن کاملDecomposition of nitramine energetic materials in excited electronic states: RDX and HMX.
Ultraviolet excitation (8-ns duration) is employed to study the decomposition of RDX (1,3,5-trinitro-1,3,5-triazacyclohexane) and HMX (1,3,5,7-tetranitro-1,3,5,7-tetrazacyclooctane) from their first excited electronic states. Isolated RDX and HMX are generated in the gas phase utilizing a combination of matrix-assisted laser desorption and supersonic jet expansion techniques. The NO molecule is...
متن کاملPhotodegradation of HMX and RDX in the Presence of Nanocatalyst of Zinc Sulfide Doped with Copper
Nanoparticles of zinc sulfide as undoped and doped with copper were used as photocatalyst in the photodegradation of HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) and RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) as nitramine explosives under UV and Vis irradiations. Photoreactivity of doped zinc sulfide was varied with dopant, mole fraction of dopant to zinc ion, pH of solut...
متن کاملThe Fate of Nitroaromatic (tnt) and Nitramine (rdx and Hmx) Explosives in Fractured and Weathered Soils
We investigated the fate of explosives compounds in slurries containing fractured and weathered soil particles. Three soils were crushed with a piston to emulate detonation-induced fracturing. We used X-ray diffraction, scanning electron microscopy and gas adsorption surface area measurements to quantify the mineralogies and surfaces of the weathered and fractured soil particles. Soil batch slu...
