- Particles with improved solubilization capacity
-
A particle is disclosed that comprises a first volume of hydrophobe-rich material with tunable dissolution and solubilization characteristics and a distinct second volume of nanostructured nonlamellar liquid crystalline material, said second volume containing said first domain and being capable of being in equilibrium with said first volume. Preferably, the nanostructured nonlamellar liquid crystalline material is capable of being in equilibrium with a polar solvent or a water-immiscible solvent or both.

- Process for the production of high energy materials
-
A process for the production of a high energy nitrate ester involves reacting, in an inert organic solvent, a heterocyclic compound, selected from oxiranes, oxetanes, N-substituted aziridines and N-substituted azetidines, with either N2 O4 or N2 O5, and when the compound is reacted with N2 O4, oxidizing the O- or N-nitrate substituents or substituent in the product to O- or N-nitrate substituent or substituents. The remaining ring carbon atoms on the heterocyclic compound may be substituted or unsubstituted. Preferred substituent groups for the C and/or N ring atoms on the compound include alkyl, cyanoalkyl, haloalkyl, nitroalkyl, and substituted aryl. Several novel nitrate ester are also provided, including nitrated derivatives of polybutadiene, in which between 1% and 25% of the carbon atoms in the polymer are substituted by vicinal nitrate ester (--ONO2) groups.
