Propellants, Explosives, Pyrotechnics, Volume 46, Issue 7, Page 1136-1149, July 2021., 2021 Abstract Concerns surround whether insensitive (or any) energetic materials are more dangerous to handle when exposed to abnormal thermal environments. This study characterizes the residual material remaining after LX‐17 (92.5 % 1,3,5‐triamino 2,4,6‐trinitro benzene (TATB) and 7.5 % Kel‐F) is exposed to various thermal environments in a sealed small ...

Toxicity Assessment of Energetic Materials by Using the Luminescent Bacteria Inhibition Test
Propellants, Explosives, Pyrotechnics, Volume 46, Issue 1, Page 114-123, January 2021., 2021 Abstract The luminescent bacteria inhibition test using Aliivibrio fischeri is a well‐established method to determine the aquatic toxicity of soluble chemicals. More precisely, the effective concentration (EC50) after 15 and 30 min is determined in this test. The inhibition of natural bioluminescence of these bacteria gives a first idea of the toxicity

Crystal Structures of Furazanes [PDF]
Crystals, 2015 Several nitrogen-rich salts of 3-nitramino-4-nitrofurazane and dinitraminoazoxyfurazane were synthesized and characterized by various spectroscopic methods. The crystal structures were determined by low temperature single crystal X-ray diffraction. Moreover the sensitivities toward thermal and mechanical stimuli were determined by differential thermal ...

Propellants, Explosives, Pyrotechnics, EarlyView.Ammonium dinitramide (ADN) and 3,4‐Diaminofurazan (DAF) form a 1:1 energetic cocrystal. We report its crystal structure and spectroscopic signature and evaluate thermal stability, decomposition behavior, hygroscopicity, and combustion properties. Propellant performance calculations benchmark the material against guanylurea dinitramide (GuDN) and ...
