Rapid fragmentation contributing to the low heat resistance of energetic materials
Heat resistance is a basic and crucial characteristic of energetic materials (EMs), and always accounted in development and application. Compared with the clear origin of the high heat resistance of EMs, the mechanism for the low heat resistance remains ...

Expression of a Drosophila glutathione transferase in Arabidopsis confers ability to detoxify the environmental pollutant, and explosive, 2,4,6-trinitrotoluene [PDF]
The explosive 2,4,6-trinitrotoluene (TNT) is a significant, global environmental pollutant that is both toxic and recalcitrant to degradation. Given the sheer scale and inaccessible nature of contaminated areas, phytoremediation may be a viable clean-up ...

Supramolecular Gels as Active Tools for Reaction Engineering
The unique combination of environments within gels, self‐assembled from low‐molecular‐weight gelators, offers the ability to control reactivity in new ways, achieving unique reaction outcomes, leading to the emerging concept of supramolecular gels as nanoreactors. Smart chemical engineering methods enable the use of such gels to fabricate materials and

Explanation of the colossal detonation sensitivity of silicon pentaerythritol tetranitrate (Si-PETN) explosive [PDF]
DFT calculations have identified the novel rearrangement shown here for decomposition of the Si derivative of the PETN explosive [pentaerythritol tetranitrate (PETN), C(CH_2ONO_2)_4] that explains the very dramatic increase in sensitivity observed ...

Characterization of Ultrafast Decomposition Dynamics in Nitrate Esters
ABSTRACT Ignition of energetic materials initiates chemical reactions on atomic length scales within femtoseconds, making these reactions difficult to investigate experimentally. The technique of femtosecond time‐resolved mass spectrometry (FTRMS) can capture molecular rearrangement and bond‐breaking events in isolated molecules with sub‐50 femtosecond

Reactive Molecular Dynamics Simulations of Shock Through a Single Crystal of Pentaerythritol Tetranitrate [PDF]
Large-scale molecular dynamics simulations and the reactive force field ReaxFF were used to study shock-induced initiation in crystalline pentaerythritol tetranitrate (PETN). In the calculations, a PETN single crystal was impacted against a wall, driving
