The combustion of a well-stirred system of gases which result from the decomposition of cyclotrimethylenetrinitramine (RDX), a common solid explosive, is studied using the technique of intrinsic low-dimensional manifolds (ILDM). The method provides a systematic way to overcome the severe stiffness which is associated with full models of gas phase RDX combustion, and thus significantly improve c...

A compact membrane-based displacement immunoassay has been designed for rapid detection of explosive compounds 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) at high femtomole levels. The system consists of activated porous membranes, onto which either TNT or RDX antibodies are immobilized, that are inserted into microreactor columns, incorporated into a flow syst...

Abstract Reactive force fields have enabled an atomic level description of a wide range phenomena, from chemistry at extreme conditions to the operation electrochemical devices and catalysis. While significant insight semi-quantitative understanding been drawn such work, accuracy reactive limits quantitative predictions. We developed neural network field (NNRF) for CHNO systems describe decompo...

Abstract A new energetic cocrystal of 2,4,6,8,10,12‐hexanitrohexaazaisowurtzitane (CL‐20) and 1,4‐dinitropyrazole (1,4‐DNP) with a 1 : molar ratio was prepared by slow solvent evaporation. This belongs to monoclinic system P 2 / c space group formed mainly the CH−O, CH−N, NO −π interactions through analyzing structures interactions. CL‐20/1,4‐DNP has melting point 132 °C decomposition temperatu...

Abstract The introduction of carbon nanotubes (CNTs) in the preparation nano-lead oxide (PbO) can effectively solve problem easy agglomeration oxide. This study used concentrated nitric acid and sulfuric mixed (volume ratio 1:3) to oxidize at 90 °C temperature for 0.5 h. Using oxidized CNTs as carriers, Pb(OAc) 2 · 3H O precursor, ammonia a precipitator, PbO/CNTs complexes were prepared by chem...

The feasibility of exploiting plasma chemistry to study the chemical reactions between metallic nanoparticles and molecular explosives such as cyclotrimethylenetrinitramine (RDX) has been demonstrated. This method, based on laser-induced breakdown spectroscopy, involves the production of nanoparticles in a laser-induced plasma and the simultaneous observation of time-resolved atomic and molecul...

Cylotrimethylenetrinitramine (RDX), with the chemical formula C3H6N6O6,is an energetic organic molecule used widely in military and industrial commodities ofexplosives. By stimulating RDX through exerting temperature or mechanical conditionssuch as impact or friction, decomposition reaction occurs at a very high rate. Moleculardynamics techniques and LAMMPS code with Rea...

The absorption spectrum of the explosive 1,3,5-trinitro-1,3,5-triazacyclohexane sRDXd has been measured using a conventional Fourier transform infrared spectroscopy and by terahertz pulsed spectroscopy. Seven absorption features in the spectral range of 5–120 cm−1 have been observed and identified as the fingerprint of RDX. Furthermore, the spatial distribution of individual chemical substances...
