Crumpled graphene-encapsulated Si nanoparticles. (A) Schematic drawing illustrating aerosol-assisted capillary assembly of crumpled-graphene-wrapped Si nanoparticles. Aqueous dispersion of GO and Si particles was nebulized to create a mist of aerosol droplets, which were passed through a preheated tube furnace. During evaporation, GO sheets first migrated to the surface of the droplets and then tightly wrapped the Si particles upon complete evaporation.
