Abstract: The remaining dynamical degrees of freedom of molecular fluids confined into capillaries of nano to sub-nanometre diameter are of fundamental relevance for future developments in the field of nanofluidics. These properties cannot be simply deduced from the bulk one since the derivation of macroscopic hydrodynamics most usually breaks down in nanoporous channels and additional effects have to be considered. In the present contribution, we review some general phenomena, which are expected to occur when manipulating fluids under confinement and ultraconfinement conditions.

Keywords: confinement; mesoporous; fluidics; nanotubes; quenched disorder; incommensurability; sliding; translational diffusion; molecular fluids; nanotechnology; nanofluidics.
