A liquid/liquid interface excited by stimulation with water

Abstract. An immiscible interface, which was composed of CaCl2 aqueous and ester phases, was excited by the addition of a small amount of water. The excitation, i.e., burst and flow at the interface, was observed above a critical concentration of CaCl2 in the aqueous phase. The critical concentration and degree of excitation depended on the kind of ester. The mechanism of excitation is disc…
