Query: Phase diagrams for sticky rods in bulk and in a monolayer from a lattice
  free-energy functional for anisotropic particles with depletion attractions   A density functional of fundamental measure type for a lattice model of
anisotropic particles with hard-core repulsions and effective attractions is
derived in the spirit of the Asakura-Oosawa model. Through polymeric lattice
particles of various size and shape, effective attractions of different
strength and range between the colloids can be generated. The functional is
applied to the determination of phase diagrams for sticky rods of length $L$ in
two dimensions, in three dimensions and in a monolayer system on a neutral
substrate. In all cases, there is a competition between ordering and gas-liquid
transitions. In two dimensions, this gives rise to a tricritical point, whereas
in three dimensions, the isotropic-nematic transition crosses over smoothly to
a gas-nematic liquid transition. The richest phase behavior is found for the
monolayer system. For $L = 2$, two stable critical points are found
corresponding to a standard gas-liquid transition and a nematic liquid-liquid
transition. For $L = 3$, the gas-liquid transition becomes metastable.
