The effects of two common binders (BR and F binder) on the thermal decomposition HMX molecules during linear heating were studied by molecular dynamics simulation. It was found that both can induce reaction earlier, promote conversion intermediate products to stable products, reduce activation energy potential barrier system. induction binder in composite system makes initial appear at interfac...

Adsorption to GAC is an effective ·method for removing high explosives (HE) compounds from water, but no permanent treatment is achieved. Bioregeneration, which treats adsorbed contaminants by desorption and biodegradation, is being developed as a method for reducing GAC usage rates and permanently degrading RDX and HMX. Because desorption is often the limiting mass transfer mechanism in bioreg...

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 solution, dosag...

Crystals of energetic materials, such as HMX, embedded in plastic binders are the building blocks plastic-bonded explosives. Such heterogeneous materials contain microstructural features sharp corners, interfaces between crystal and binder, intra- extra-granular voids, other defects. Energy localization or hotspots arise during shock interaction with heterogeneities, leading to initiation PBXs....

To improve the safety of cyclotetramethylenetetranitramine (HMX) particles, polymer thermoplastic polyurethane elastomer (TPU) and nitrocellulose (NC) were introduced to coat HMX powder by water-solution suspension method internal solution method, respectively. Scanning electron microscope (SEM) X-ray photo-electron spectrometry (XPS) employed characterize samples role NC TPU in coating process...

We measured the 229 nm absolute ultraviolet (UV) Raman cross-sections of the explosives trinitrotoluene (TNT), pentaerythritol tetranitrate (PETN), cyclotrimethylene-trinitramine (RDX), the chemically related nitroamine explosive HMX, and ammonium nitrate in solution. The 229 nm Raman cross-sections are 1000-fold greater than those excited in the near-infrared and visible spectral regions. Deep...
