1. A method of making RDX nanoparticles, comprising
injecting a RDX/acetone solution having a concentration of RDX in acetone of 0.5-1.0 mg RDX/mL acetone through an inner tube of a turbulent mixer to form an inner flow;
injecting an anti-solvent through an outer tube of said turbulent mixer to form an outer flow, wherein the inner tube is concentric with the outer tube, wherein turbulent mixing of the inner flow and outer flow precipitates a plurality of nanoparticles of RDX having a size range of from 95 nm to 151 nm, an average size of 123 nm and a spherical morphology.
