A core/shell nanoparticle with enhanced emission comprises a fluorescent conjugated polymer core that is encapsulated by an amphiphilic block copolymer shell. The core/shell nanoparticle structure confines the electronic charge to improve quantum yield and is water soluble to enable low-cost and environmentally friendly processing.

Self-assembly method for core/shell nanoparticles with enhanced emission

A new, rapid and inexpensive synthesis method for monodispersed triaminotrinitrobenzene (TATB) microparticles based on micelle-confined precipitation that enables control of microscopic morphology. The morphology of the TATB microparticles can be tuned between quasi-spherical and faceted by controlling the speed of recrystallization. The method enables improved performance and production consistency of TATB explosives for military grade explosives and propellants

Method for the preparation of uniform triaminotrinitrobenzene microparticles

A surfactant-assisted self-assembly method can be used to crystallize energetic materials with controlled morphology. Microparticles of hexanitrohexaazaisowurtzitane (CL-20) formed by this method may have enhanced functional reproducibility due to their monodisperse nature, and decreased shock sensitivity due to their sub-2 &#x3bc;m particle size.
