This work investigates the stability of trace (tens of nanograms) deposits of six explosives: erythritol tetranitrate (ETN), pentaerythritol tetranitrate (PETN), cyclotrimethylenetrinitramine (RDX), cyclotetramethylenetetranitramine (HMX), 2,4,6-trinitrotoluene (TNT), and 2,4,6-trinitrophenylmethylnitramine (tetryl) to determine environmental stabilities and lifetimes of trace level materials. ...

This research was performed using Becke’s three-parameter hybrid functional approach with non-local correlation provided by Lee, Yang, and Parr the cc-pVTZ basis set. The geometry, total energy, heat of formation most stable conformers nitramines under study were obtained to obtain density, resistance shock stimuli, detonation pressure, velocity materials study. results allow us predict new mul...

Enterobacter cloacae NAD(P)H:nitroreductase (NR; EC 1.6.99.7) catalyzes the reduction of a series of nitroaromatic compounds with steady-state bimolecular rate constants (kcat/Km) ranging from 10(4) to 10(7) M(-1) s(-1). In agreement with a previously proposed scheme of two-step four-electron reduction of nitroaromatics by NR (Koder, R. L., and Miller, A.-F. (1998) Biochim. Biophys. Acta 1387, ...

Do you want to prepare a transition metal complex having tridentate PEP (E=Si, Ge, Sn) tetryl ligand? This review by Cabeza and García-Álvarez shows how this synthetic problem has been addressed in the past, systematically describing currently known types of ligand frameworks heavier group 14 atom (E) compounds that have used as metal-free precursors.

Abstract The electrochemical reduction of four organic explosive compounds, 1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocane (HMX), 1,3,5‐trinitro‐1,3,5‐triazinane (RDX), pentaerythritol tetranitrate (PETN) and 2,4,6‐trinitrophenylmethylnitramine (tetryl), is studied in eight room temperature ionic liquids (RTILs). In all RTILs, the peaks were highly complicated, but much better resolved than previous st...

A polyethylenimine polymer derivatized with pyrene moieties suitable for the fluorescence-based detection of nitroaromatic explosives (NAC) in aqueous systems is described. The system exhibits an exceptionally wide dynamic sensing range of 7 orders of magnitude (from 33 ppt to 225 ppm TNT or Tetryl). This broad range was achieved by the combination of FRET and PET sensing mechanisms in a single...

In this report we present the synthesis and the detailed electron paramagnetic resonance (EPR) spectroscopic characterization of novel trivalent lead- and tin-based radicals comprising sterically demanding germyl substituents. The investigated radicals are derived from the recently reported trihypersilyl-substituted tetryl radicals *PbHyp3 and *SnHyp3. The tetryl radicals *Pb(Ge(SiMe3)3)3 (8), ...
