Query: First-order phase transitions in lattice bilayers of Janus-like
  particles: Monte Carlo simulations   The first-order phase transitions in the lattice model of Janus-like
particles confined in slit-like pores are studied. We assume a cubic lattice
with molecules that can freely change their orientation on a lattice site.
Moreover, the molecules can interact with the pore walls with
orientation-dependent forces. The performed calculations are limited to the
cases of bilayers. Our emphasis is on the competition between the fluid-wall
and fluid-fluid interactions. The oriented structures formed in the systems in
which the fluid-wall interactions acting contrary to the fluid-fluid
interactions differ from those appearing in the systems with neutral walls or
with walls attracting the repulsive parts of fluid molecules.
