Cascade partial coalescence phenomena at electrolyte-oil interfaces and determination of bounds for the surface potentialElectronic supplementary information (ESI) available: (1) Movies of the cascade partial coalescence for toluene and n-heptane droplets in water (toluene_in_water.mp4 and heptane_in_water.mp4) and in 1 M salt solutions (toluene_in_1MKCl.mp4 and heptane_in_1MKCl.mp4).
