Query: Van der Waals interaction between a moving nano-cylinder and a liquid
  thin film   We study the static and dynamic interaction between a horizontal cylindrical
nano-probe and a thin liquid film. The effects of the physical and geometrical
parameters, with a special focus on the film thickness, the probe speed, and
the distance between the probe and the free surface are analyzed. Deformation
profiles have been computed numerically from a Reynolds lubrication equation,
coupled to a modified Young-Laplace equation, which takes into account the
probe/liquid and the liquid/substrate non-retarded van der Waals interactions.
We have found that the film thickness and the probe speed have a significant
effect on the threshold separation distance below which the jump-to-contact
instability is triggered. These results encourage the use of horizontal
cylindrical nano-probes to scan thin liquid films, in order to determine either
the physical or geometrical properties of the latter, through the measurement
of interaction forces.
