TL;DR: The time evolution of the potential energy can be described reasonably well with a single exponential function from which an overall characteristic time of decomposition that increases with decreasing density and shows an Arrhenius temperature dependence is obtained.
Abstract: We use the recently developed reactive force field ReaxFF with molecular dynamics to study thermal induced chemistry in RDX [cyclic-[CH2N(NO2)]3] at various temperatures and densities. We find that the time evolution of the potential energy can be described reasonably well with a single exponential function from which we obtain an overall characteristic time of decomposition that increases with decreasing density and shows an Arrhenius temperature dependence. These characteristic timescales are in reasonable quantitative agreement with experimental measurements in a similar energetic material, HMX [cyclic-[CH2N(NO2)]4]. Our simulations show that the equilibrium population of CO and CO2 (as well as their time evolution) depend strongly of density: at low density almost all carbon atoms form CO molecules; as the density increases larger aggregates of carbon appear leading to a C deficient gas phase and the appearance of CO2 molecules. The equilibrium populations of N2 and H2O are more insensitive with respect to density and form in the early stages of the decomposition process with similar timescales.

TL;DR: In this article, a method for estimating critical temperatures (Tb) of thermal explosion for energetic materials is derived from Semenov's thermal explosion theory and the non-isothermal kinetic equation dα/dt = Af(α)e−E/RT using reasonable hypotheses.

TL;DR: The preparation strategies adopted for nanostructured energetic composites and the research achievements thus far are comprehensively discussed in this review.
Abstract: Nanotechnology has stimulated revolutionary advances in many scientific and industrial fields, particularly in energetic materials. Powder mixing is the simplest and most traditional method to prepare nanoenergetic composites, and preliminary findings have shown that these composites perform more effectively than their micro- or macro-sized counterparts in terms of energy release, ignition, and combustion. Powder mixing technology represents only the minimum capability of nanotechnology to boost the development of energetic material research, and it has intrinsic limitations, namely, random distribution of fuel and oxidizer particles, inevitable fuel pre-oxidation, and non-intimate contact between reactants. As an alternative, nanostructured energetic composites can be prepared through a delicately designed process. These composites outperform powder-mixed nanocomposites in numerous ways; therefore, we comprehensively discuss the preparation strategies adopted for nanostructured energetic composites and t...

TL;DR: In this paper, large-scale syntheses of nitrogen-rich 5,5′-hydrazinebistetrazole (HBT) and bis(3,4,5-triamino-1,2,4-triazolium) 5, 5′-azotetrazolate (G2ZT) with high yields and purities on a multigram scale are introduced.
Abstract: Large-scale syntheses of nitrogen-rich 5,5′-hydrazinebistetrazole (HBT) (or 1,2-ditetrazolylhydrazine) and bis(3,4,5-triamino-1,2,4-triazolium) 5,5′-azotetrazolate (G2ZT) with high yields and purities on a multigram scale are introduced. DSC analysis showed good thermal stabilities for both materials (>200 °C) and their long-term stabilities were assessed by TSC (thermal safety calorimetry). Because molecular structures play an important role in the properties of an energetic material, hydrogen bonding in both compounds is described in terms of graph-set analysis. The extensive hydrogen bonding in the structures seems to account for their relatively high densities (HBT, ρ = 1.841 g cm−3; and G2ZT, ρ = 1.708 g cm−3). The heats of combustion of the two compounds were calculated (ΔcU°(HBT) = −2396 cal g−1 and ΔcU°(G2ZT) = −2775 cal g−1) and combined with the experimentally determined densitites (X-ray) and the molecular formulas to calculate the detonation pressures (P) and velocities (D) using the EXPLO5 co...
