17. w of ∼0.04 for drop-like objects would favour a translational movement in which the larger rounded part (b) is in front. Nevertheless, experiments show that the smaller tip section (t) enters the cylinder more frequently. This is because the b-section collides with the wall next to the hole more frequently than does the tip section.
18. The Boltzmann factor results from a minimisation of the free energy F of an adlayer where a small number of dipoles undergo orientational disorder [1]. By this calculation we account only for a change in the attachment energy and for configurational entropy. As derived, Eq. (2) applies to cases where the equilibrium in Eq. (1) is on either side.
