Title: Binary fluid mixture confined between macroparticles

Abstract: 
        A binary fluid mixture of component 1 and 2, which is confined
        between macroparticles separated by L, is analyzed using the
        RISM theory.
        Hard-sphere interaction is assumed for all the pairs except for
        particles of component 1 interacting through attractive
        potential. Component 2, the minor component, is enriched
        near each macroparticle.When the concentration of
        component 2 in the bulk Y2 is sufficiently high, the following
        is observed. As L decreases component 2 is further enriched
        in the confined domain, and at L=Lt the theory exhibits a
        signal of the surface-induces phase transition. As Y2 increases
        Lt becomes larger.
