eng	Successful journey in preparation of the energy-safety balanced cocrystals of attractive nitramines via coagglomeration	Co-agglomeration of the co-precipitated micro-particles of nitramines themselves or with polynitroarenes by the slurry method is a unique crystal engineering approach to modify the energetic properties of attractive nitramines like CL20, HMX, BCHMX, RDX etc. The properties and structural modification in the 45+ co-agglomerated crystals (CACs) newly prepared in our laboratory. There are notable variations in the crystal morphologies and packing of crystals, including key properties like relatively high density, melting point, impact sensitivity, and detonation properties. These CACs are in the overwhelming majority showing properties like co-crystals. Apart from these aspects, co-agglomeration provides a huge opportunity to tune the key properties and performance of existing energetic materials and is easy to scale-up for the industrial level. These preliminary results also suggest that chemical engineering factors are involved in the preparation of CACs, as in conventional crystallization. The optimization of them should be a matter of downstream technological research.	Nitramines; Co-agglomeration; Co-crystals; Impact sensitivity; Detonation parameters
