abstract = {The dynamics of squeeze-out of thin liquid films between
two solids is perhaps the most central topic in tribology.
It is directly relevant for wear and indirectly involved in
many other important processes, e.g., adhesion and friction.
In this review we present a broad overview of the basic
principles of squeeze-out, and present a number of
applications to adhesion, friction and wear. We first
describe the squeezing of 'thick' liquid films (thickness
larger than similar to100 Angstrom), which can be described
using the Navier-Stokes equations of hydrodynamics, and
present experimental illustrations for soft solids (rubber)
and hard solids (mica). Next we consider molecularly thin
liquid films. Here the squeeze-out occurs in a quantized
manner involving a monolayer at each step. We discuss the
nature of the nucleation of n --> n - 1 monolayer
squeeze-out, where n is the number of trapped monolayers. We
consider in detail the nature of the spreading which follows
the nucleation and show that the boundary line may exhibit
instabilities. Sometimes the squeeze-out is incomplete,
resulting in trapped islands. These islands may be pinned,
or else they drift slowly to the periphery of the contact
area where they get squeezed out through narrow liquid
channels. We consider also dewetting at soft interfaces and
present an application to the adhesion of soft objects on
wet substrates. Finally, we present molecular dynamics and
kinetic Monte Carlo simulation results on various aspects of
squeeze-out for liquid-like and solid-like lubrication
films, and discuss the implications for wear.},
