Energetic cocrystals (ECCs), as a promising alternative to new energetic materials, are attracting increasing attention. However, it is challenge accurately describe their structural and properties using quantum chemistry approaches. In this work, 13 dispersion-corrected density function theory potentials, well the original PBE functional, adopted evaluate accuracy efficiency in describing lattice parameters energy of 53 ECCs. These ECCs classified into three categories terms characteristics intermolecular interactions therein; that is, C-ECCs, T-ECCs, H-ECCs feature common weak interaction, π-stacking, rather strong hydrogen bonds (HBs), respectively. Generally, PBE-D3(0), PBE-D3(BJ), PBE-TS, PBE-TS(HI), optPBE-vdW, vdW-DF2 methods provide good description for all ECCs, these somewhat dependent on type ECCs; PBE-D3(BJ) best H-ECCs, contrast, most reliable prediction among six accurate potentials parameters. Accounting both time consumption, PBE-D2, recommended dominated by interactions, HBs, This work provides guidelines select appropriate molecular crystals.

In order to reduce the hygroscopicity of ammonium dinitramide (ADN), four different ADN/nitrocellulose (NC) samples were prepared from acetone solutions using electrostatic spraying, with concentrations 2.5, 5, 7.5, and 10 mg ml−1. The morphology was analyzed by scanning electron microscopy, regular uniform size examined x-ray powder diffraction differential calorimetry investigate crystal structure obtain their thermal decomposition properties. Additionally, mechanical sensitivity microspheres also obtained these studies. ADN/NC energetic complexes at a concentration 5 ml−1 found be spherical, in shape, size. apparent activation energy critical temperature for explosion reduced. impact sensitivities comparable those raw material, whereas friction enhanced. Water absorption tests showed that moisture ADN 32.12%, sample after coating 3.75%. significantly

Abstract CL‐20/4,5‐MDNI exists in two cocrystal forms with different stoichiometric ratios of 1:1 and 1:3. The properties (such as blast performance, thermal sensitivity, density) the cocrystals are significantly different, but both expected to become new high‐energy insensitive explosives have good applications. AE model molecular dynamics were used simulate crystal morphology important planes 1:3 under vacuum conditions, well five solvents temperatures. has main growth (002), (102), (111), (020) (021), which (002) largest proportion. six (001), (010), (011), (100), (101) (001) accounts for aspect ratio acetonitrile methanol 1.936 1.680, respectively. results consistent experiments, certain guiding significance obtain a closer spherical shape.
