abstract = {The properties of linear alkane lubricants confined between
two approaching solids are investigated by a model that
accounts for the roughness, curvature and elastic properties
of the solid surfaces. We consider linear alkanes of
different chain lengths from ${{\rm{C}}}_{3}{{\rm{H}}}_{8}$
to ${{\rm{C}}}_{16}{{\rm{H}}}_{34}$, confined between
corrugated solid walls. The pressure necessary to squeeze
out the lubricant increases rapidly with the alkane chain
length, but is always much lower than in the case of smooth
surfaces. The longest alkanes form domains of ordered chains
and the squeeze-out appears to nucleate in the more
disordered regions between these domains. The short alkanes
stay fluid-like during the entire squeeze out process which
result in a very small squeeze-out pressure which is almost
constant during the squeeze-out of the last monolayer of the
fluid. In all cases we observe lubricant trapped in the
valley of the surface roughness, which cannot be removed
independent of the magnitude of the squeezing pressures.},
