Consecutive equilibrium configurations of a Lennard-Jones fluid in a nano-capillary with hydrophilic bottom and left walls and hydrophobic top wall opening into a reservoir containing vapour of the same fluid. The x- and y-dimensions are in units of molecular diameters. The pressure in the reservoir is being slowly increased, which results in partial filling of the capillary. The result is obtained from a fully microscopic statistical mechanical model.
