title: Photoisomerisation behaviour of azobenzene crystals hybridised with silica nanoparticles by dry grinding.
abstract: The dry grinding of azobenzene crystals with silica nanoparticles gave nanohybrids, which exhibited reversible photoisomerisation in water through linearly consecutive processes. The hybrids mill-dispersed in an aqueous PVA solution displayed different spectral changes due to the partial dissolution of azobenzene in PVA coils in water.
