Accelerated Dissolution of Fatty Acid Particles at the Oil-Water Interface

摘要

We found self-motion and accelerated dissolution of a fatty acid particle at the oil-water interface. The dissolution time at the interface was 15-20 times shorter than that in the oil phase. The driving force of the self-motion and the accelerated dissolution is the Marangoni flow induced by the spatial heterogeneity of a fatty acid layer at the oil-water interface.
