Progress and performance of energetic materials: open dataset, tool, and implications for synthesis

Abstract

During the development of novel energetic materials first analysis of synthesized compound includes both physico-chemical characterization and energetic potential evaluation. Evaluation of energetic performance includes determination of the detonation parameters,...

Novel family of nitrogen-rich energetic (1,2,4-triazolyl) furoxan salts with balanced performance

“…Detonation performance parameters (detonation velocity at maximal density and Chapman-Jouguet pressure) were calculated by recently suggested set of empirical methods from PILEM application ( Muravyev et al, 2022 ). Note, that the accuracy of the utilized in PILEM empirical methods is comparable to benchmark thermodynamic code EXPLO5.…”

Renaissance of dinitroazetidine: novel hybrid energetic boosters and oxidizers

“…All reactions carried out in well-cleaned oven-dried glassware with magnetic stirring. 1 H, 13 C and 14 N NMR spectra were recorded on a Bruker AM-300 (300.13, 75.47 MHz and 21.69 MHz, respectively) spectrometer and referenced to the residual solvent peak. The chemical shifts are reported in ppm (δ).…”

“…13 C{ 1 H} NMR (75.5 MHz, acetone-d 6 ) δ C : 58.5, 59.9, 105.0, 106.7, 152.0, 156.9. 14 3,3-Dinitro-1-(2,2,2-trinitroethyl)azetidine (4). Compound 4 was prepared according to a previously published procedure.…”

“…[5][6][7][8][9][10][11][12] Over the last few decades, search for novel high-energy structures has been focused on HEDMs incorporating various heterocyclic frameworks. 13,14 In contrast to nitroaromatic and carbocyclic explosives, such HEDMs have good ecological profiles and possess high positive enthalpies of formation. 15 In this sense, 1,2,5-oxadiazole N-oxide (furoxan) attracts significant attention due to a high positive enthalpy of formation (198.5 kJ mol −1 ) and a huge nitrogen-oxygen content present within the core.…”

Promising Thermally Stable Energetic Materials with the Combination of Pyrazole–1,3,4-Oxadiazole and Pyrazole–1,2,4-Triazole Backbones: Facile Synthesis and Energetic Performance

“…All the compounds are insensitive to impact (>30 J) and friction (>360 N). In addition, compounds 4,6,10,14,17,21,22,and 23 show high onset decomposition temperature (T d between 238 and 397 °C) than the benchmark energetic materials RDX (T d = 210 °C), HMX (279 °C), and thermally stable HNS (318 °C). It is noteworthy that the pyrazole−oxadiazole and pyrazole− triazole backbones greatly influence their physicochemical and energetic properties.…”
