Evolution of shape isotropy in silica microparticles induced by the base

Evolution of shape isotropy in silica microparticles induced by the base Evolution of shape isotropy in silica microparticles synthesized by sol-gel method is examined by varying the concentration of ammonia. The morphology evolved from worm-like structure to monodisperse spheres. The shape evolution is attributed to the “Pearl-necklace” mechanism wherein the worm-like silica particles due to constrain in its mobility, collapse to an energetically favored spherical morphology with intermediate doll/frustum cone-like morphologies. Plausible reason for the collapse in morphology could be the conformational entropy of the worm-like particles to explore various re-arranged morphologies arising due to Rayleigh-Plateau instability. The collapse in morphology is analogous to the coil to globule transition in polymeric systems; however, the length scales explored in the present study are of the order of micrometers, and the collapse depends on the base concentration. The present system will serve as a model for understanding the various re-arrangements undergoing during the compaction of biological moieties. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Colloid Polymer Science Springer Journals
