The interface engine: Experimental consequences

A light microscopy study confirms spontaneous emulsification at the quiescent, thermally equilibrated interface between pure oil and pure water during the chemical equilibration period. The process is qualitatively explained within the frame of the classical nucleation theory assuming a mixed interface layer between the two liquids in contact allowing supersaturation.
