Query: Wall adsorption of a colloidal particle moving in a quiescent partially
  wetting fluid   In thermal equilibrium, a colloidal particle between two parallel plates
immersed in a fluid which partially wets both the particle and the plates, is
attracted by the walls. However, if the particle moves parallel to the plates,
a hydrodynamic lift force away from the plates arises in the limit of low
Reynolds number. We study theoretically the competition of these two effects
and identify the range of velocity in which the velocity may serve as a
parameter controlling the adsorption in microflows.
