| Outline of Final Research Achievements |
The present work eludicated the microscopic mechanisms of ion transfer through liquid-liquid interfaces. It has been predicted by MD simulation that the ion transfer could induce transient interfacial structure, called "water finger". This work defined a proper coordinate w to describe the structure of water finger formation, and thereby revealed free energy profiles of ion transport using the newly defined coordinate w. We revealed that the structural transition associated to the water finger formation/break has a hidden barrier of free energy. By considering the hidden barrier, we have successfully elucidated the experimentally observed rate constants of interfacial ion tranport, which are significantly smaller than that of the diffusion-limited process.
