Abstract
CONTEXT Explosives have a wide range of applications in many fields due to their high energy and high density. Recently, a new synthesized co-crystal explosive DAF:ADNP presents high detonation performance and low sensitivity. This work is aimed to understand how the structure and intermolecular interactions affect the performance of the DAF:ADNP co-crystal. The results indicate that the formed π-π interactions and stronger hydrogen bonds in the co-crystal enhance its stability and its impact sensitivity is reduced. The strong intralayer H···N and H···O interactions and interlayer π-π stacking are the main driving force for the formation of the co-crystal. Compared with the pure crystals, the detonation performance of the co-crystal slightly decreases, while its sensitivity reduces. METHODS All calculations were used the DFT-PBE-D method with Vanderbilt-type ultrasoft pseudopotentials and plane wave (340.0 eV) in the CASTEP package. Radial distribution function were calculated by NVT-MD simulations for 100 ps with a time step of 1 fs at 298 K. Hirshfeld surfaces were generated by CrystalExplorer 3.0 and reduced density gradient analyses were performed by Multiwfn 3.0.

Abstract
The crystal models of trans-1,4,5,8-tetranitro-1,4,5,8-tetraazadecalin (TNAD), hexanitrohexaazaisowurtzitane (CL-20), and CL-20/TNAD cocrystal explosive with different component ratios were established. Molecular dynamics (MD) method was applied to predict the stability, sensitivity, energetic properties, and mechanical properties. The effect of component ratio on properties of CL-20/TNAD cocrystal explosive was investigated and estimated. Results show that the cocrystal model with component ratio in 1:1 exhibits the highest binding energy and it is more stable. In CL-20/TNAD cocrystal explosive, the interaction energy of trigger bond is increased by 0.8 ~ 15.0 kJ/mol, implying that the mechanical sensitivity of CL-20/TNAD cocrystal explosive is lower than CL-20 and the safety is effectively improved. Compared with raw CL-20, the crystal density of cocrystal explosive is declined by 0.014 ~ 0.193 g/cm3, detonation velocity is declined by 39 ~ 755 m/s, and detonation pressure is declined by 0.95 ~ 11.40 GPa; namely the energy density of CL-20/TNAD cocrystal explosive is lower than CL-20. The cocrystal explosives with component ratio in 10:1 ~ 1:1 still exhibit desirable detonation performance and can be regarded as high energy density explosives. The values of tensile modulus, shear modulus, and bulk modulus of CL-20/TNAD cocrystal explosive are decreased by 0.448 ~ 10.285 GPa, 0.195 ~ 4.189 GPa, and 0.194 ~ 6.292 GPa, respectively, Cauchy pressure is increased by 0.990 ~ 5.704 GPa, meaning that the rigidity, fracture strength, and hardness of cocrystal explosive are declined, while the plastic property and ductility are increased and the mechanical properties are improved. The cocrystal model with component ratio in 1:1 has the best mechanical properties. Consequently, the CL-20/TNAD cocrystal explosive with component ratio in 1:1 is more stable and insensitive; it also has high energy density and the best mechanical properties and may be an attractive candidate for high energy explosives.

Abstract
The influence of temperature and solvent on the solid–liquid ternary phase diagrams of the 2HNIW·HMX cocrystal has been investigated. Ternary phase diagrams were constructed for the 2HNIW·HMX cocrystal in acetonitrile and ethyl acetate at 15 °C and 25 °C. HMX and HNIW showed inconsistent dissolution behavior and congruent dissolution behavior in acetonitrile and ethyl acetate, respectively. In the HMX–HNIW–acetonitrile system, the 2HNIW·HMX cocrystal has a narrow thermodynamically stable region at both temperatures. The cocrystal exhibits a wider thermodynamically stable region in the HMX–HNIW–ethyl acetate system. The results show that the choice of solvent has a crucial influence on the dissolution behavior of the cocrystal and the size and position of each region in the phase diagram, while the temperature has no apparent effect on the overall appearance of the phase diagram. By properly selecting the ratios, the 2HNIW·HMX cocrystal could be prepared by the isothermal slurry conversion crystallization method. The ternary phase diagrams of 2HNIW·HMX cocrystal system in ethyl acetate at 15 °C. In the HMX–HNIW–ethyl acetate system, HMX and HNIW showed congruent dissolution behavior, and the cocrystal exhibits a wider thermodynamically stable region.![]()
