Ultra-fine particle formation using principle of rapid expansion of supercritical solutions`
… industries that the reduction in size of a crystalline particle can lead to better performance of the drug compound, particularly for water insoluble drugs, in the final dosage form. Many particle formation techniques have been investigated in recent years by researchers to obtain …

Production and characterization of composite nano/micro sized particles by rapid expansion of supercritical solutions (ress) co-precipitation
Nanoscale composites of hexahydro-1, 3, 5-trinitro-1, 3, 5-triazine (RDX) and polymer binders were produced by co-precipitation using rapid expansion of supercritical solutions (RESS). The binders used in this study are poly (vinylidene fluoride-co-hexafluoropropylene) (VDF-HFP22), polystyrene (PS) …

Production of nanocrystalline rdx by ress : development and material characterization
The aim of the present work was to address the hazardous vulnerability of energetic materials to accidental initiation. An improved form of the explosive RDX with a significantly reduced sensitivity to stimuli including shock and impact was sought. The direction of this research was to investigate …

Formation of RDX nanoparticles by rapid expansion of supercritical solution : in situ characterization by laser scattering
… material, is highly explosive. Reduction of the sensitivity of RDX is desired for safe handling and storage in military applications. Data on the sensitivity of RDX in the 10-1000 um crystal size range suggested that the impact sensitivity could be further reduced by reduction of the …
