Temperature induced formation of particle coated non-spherical droplets

► Non-spherical emulsion droplets could be obtained by aging spherical emulsion droplets stabilized by freshly precipitated magnesium hydroxide nanoparticles at certain temperature. ► Particle concentration, oil/water ratio, aging temperature and aging time remarkably influence the formation of non-spherical emulsion droplets. ► The decrease of particle coverage on the droplet surface is the origin of non-spherical emulsion droplet formation.
