The ability of ruminal microorganisms to degrade octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (high melting explosive, HMX) as consortia from whole rumen fluid (WRF), and individually as 23 commercially available ruminal strains, was compared under anaerobic conditions. Compound degradation was monitored by high-performance liquid chromatography, followed by liquid chromatography-tandem mas...

HMX decomposition kinetics are usually calibrated in the temperature range around 200 °C. This leads to an underestimation of several orders magnitude thermal explosion times during impacts compared measurements collected Henson and Smilowitz, Non-shock initiation explosives, Shock wave science technology reference library, 2010. It highlights incomplete physics used single- or multi-stage mode...

To p robe the microstructures of ni trate est er pla sticized p olyether (NEPE) composite propellants and observe th e morphology of each constit ute in the propellant, the microstructure and elemental constitutes of NEPE propellants were investigated using scanning electron microscopy and energy dispersive X-ray spectroscopy. The ammonium perchlorate (AP) grains had a scraggy surface and were ...

The effect of replacing hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) by octahydro-1,3,5,7-tetranitro-1,3,5,7tetrazocine (HMX) in HTPB-binder on the performance, sensitivity, thermal, and mechanical properties of the sheet explosive formulation has been studied. The maximum loading of HMX was achieved up to 78 per cent in HTPB-binder system. The velocity of detonation (VOD) of HMX-based sheet e...

with HMX, performed with a simultaneous thermogravimetric modulated beam mass spectrometry (STMBMS) apparatus, and have created a reaction cycle that captures the physical processes and chemical reactions that control its decomposition. The reaction cycle is based on 9 different physical processes and 7 general chemical reactions that play a significant role in controlling the decomposition of ...

Organic mulch is a complex organic material that is typically populated with its own consortium of microorganisms. The organisms in mulch breakdown complex organics to soluble carbon, which can then be used by these and other microorganisms as an electron donor for treating RDX and HMX via reductive pathways. A bench-scale treatability study with organic mulch was conducted for the treatment of...

A continuum thermomechanochemical model of the behavior of a plastic-bonded explosive PBX 9501 formulation consisting of the energetic crystal octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine HMX embedded in a polymeric binder is developed. Our main focus is on the study of the ↔ phase transformations PTs in crystalline HMX under a complex pressure-temperature path. To reproduce the pressure-te...

We introduce a melded chemical and computational approach for probing and modeling higher-order intramolecular tertiary interactions in RNA. 2'-Hydroxyl molecular interference (HMX) identifies nucleotides in highly packed regions of an RNA by exploiting the ability of bulky adducts at the 2'-hydroxyl position to disrupt overall RNA structure. HMX was found to be exceptionally selective for quan...
