Electrospun aggregation-induced emission (AIE)-active polyhedral oligomeric silsesquioxane (POSS)-based copolymer films exhibit an approximately 9-fold increase in response to explosive vapors compared to dense films although porous copolymer films have a thickness as high as 560 ± 60 nm.

Improvised explosive devises (IEDs) represent the greatest threat to personnel deployed to combat zones. Improvements in the capacity to detect and neutralize these threats are therefore a crucial concern. Although technology can provide better protection against explosions and, perhaps, improve detection, IED detection will for the foreseeable future be dependent on the capacity of mounted and...

Extended multireference configuration interaction with singles and doubles (MR-CISD) calculations of nitroethylene (H2C═CHNO2) were carried out to investigate the photodynamical deactivation paths to the ground state. The ground (S0) and the first five valence excited electronic states (S1-S5) were investigated. In the first step, vertical excitations and potential energy curves for CH2 and NO2...

The detection of explosives and explosive-related compounds has become a heightened priority in recent years for homeland security and counter-terrorism applications. There has been a huge increase in research within this area-through both the development of new, innovative detection approaches and the improvement of existing techniques. Developments for miniaturisation, portability, field-rugg...

This review discusses the recent advances in the syntheses of high explosive energetic materials. Syntheses of some relevant modern primary explosives and secondary high explosives, and the sensitivities and properties of these molecules are provided. In addition to the synthesis of such materials, processing improvement and formulating aspects using these ingredients, where applicable, are dis...
