| Research Abstract |
Nanoscopic interfacial equilibrium condition of binary Lennard-Jones liquid phases, capillary phase separation of binary Lennard-Jones liquids in nanopores, and mass transfer phenomenon caused by capillary phase separation in nanopores are examined. The larger the value of T^* or ε(AB), the larger is Tolman's length, the smaller is the interfacial tension, and the larger is the equilibrium bulk concentration. Moreover, in nanopores, the relation between the bulk concentration and rate of mass transfer was clarified. Curvature radius of the meniscus is smaller, the inner pressure of condensed liquid in pore is lower by stronger Laplace effect. Therefore, amplified pressure difference should be occurred in condensed phase nestled between the two different bulk conditions.
