The development of microfluidic devices has recently revived the interest in "old" problems associated with transport at, or across, interfaces. As the characteristic sizes are decreased, the use of pressure gradients to transport fluids becomes problematic, and new, interface driven, methods must be considered. This has lead to new investigations of flow near interfaces, and to the conception of interfaces engineered at various scales to reduce flow friction. In this review, we discuss the present theoretical understanding of flow past solid interfaces at different length scales. We also briefly discuss the corresponding phenomenon of heat transport, and the influence of surface slip on interface driven ( electro-osmotic) flows.

Towards an understanding of induced-charge electrokinetics at large applied voltages in concentrated solutions. (2009, background): “As in the case of effective hydrodynamic slip (d<0) over hydrophobic surfaces [263,264] the slip-plane concept, although useful, obscures the true physics of the interface.”
Friction and energy dissipation mechanisms in adsorbed molecules and molecularly thin films (2012, background): “Barrat, Bocquet, and coworkers have 199–202 demonstrated that although it is well known that, at a macroscopic level, the boundary condition for a viscous fluid at a solid wall is one of “no slip” (i.”
Effective slip in pressure-driven flow past super-hydrophobic stripes (2009, background): “…fluid in a tiny channel is to exploit hydrodynamic slip, which can be generated at hydrophobic surfaces and is quantified by the slip length b (the distance within the solid at which the flow profile extrapolates to zero) (Vinogradova 1999; Bocquet & Barrat 2007; Lauga, Brenner & Stone 2007).”
Water in nonpolar confinement: from nanotubes to proteins and beyond. (2008, neutral): “With the advent of experimental methods of CNT synthesis (141, 142) and functionalization (131, 132, 143), and an improved understanding of micro- and nanofluidics (144), it is not difficult to imagine the development of nanofluidic networks to transport small quantities of fluid molecules from one ”
Superhydrophobic drag reduction in laminar flows: a critical review (2016, background): “The rapid development of nano- and microfluidic systems brought a renewed attention to the solid–liquid boundary condition during the last decade (Neto et al. 2005; Bocquet and Barrat 2007).”
Tensorial hydrodynamic slip (2008, background): “…dynamics simulations have shown that (2.1) with constant M is more robust than (1.1) with constant b, since the fluctuating slip velocity correlates better with the shear stress (normal forces) than with velocity gradients very close to the surface (Hess & Loose 1989; Bocquet & Barrat 2007).”
