Research and Development of High-performance Explosives
Developmental testing of high explosives for military applications involves small-scale formulation, safety testing, and finally detonation performance tests to verify theoretical calculations. small-scale For newly developed formulations, the process begins with small-scale mixes, thermal testing, and impact and friction sensitivity. Only then do subsequent larger scale formulations proceed to...

Combining ab initio quantum mechanics with a dipole-field model to describe acid dissociation reactions in water: First-principles free energy and entropy calculations Modeling deflagration-to-detonation transition in granular explosive pentaerythritol tetranitrate Simulated thermal decomposition and detonation of nitrogen cubane by molecular dynamics
متن کاملHigh-temperature Explosives for Insensitive-munitions Applications
We are developing new energetic structures expected to have superior insensitivity characteristics and superior performance characteristics relative to currently used insensitive high explosives. The chemical structures proposed herein are a series of zeroto low-hydrogen-content, polynitro, polycyclic heteroaromatic compounds based on novel nitrogenous heterocycles. By analogy to other nitrated...
متن کاملBiodegradation of High Explosives on Granular Activated Carbon: Enhanced Desorption of High Explosives from GAC- Batch Studies
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...
متن کاملF1-A1: Synthetic routes to new and improvised high explosives
The project deals with alternative routes for synthesis of triacetonetriperoxide (TATP) without the use of liquid peroxides. The research aims to explore commonly available chemicals which can be used as precursors along with ‘over the counter’ materials which have the ability to produce TATP. One of the most promising chemicals for the synthesis of TATP are percarbonates giving yields higher t...
