TLDR
This article used total internal reflection (TIR•FRAP) to probe the velocity of a liquid near a wall with a resolution of the order of 100 nm and showed that simple Newtonian fluids can develop slip at the wall.Abstract:
We report a novel experimental technique using total internal reflection – fluorescence recovery after photobleaching (TIR‐FRAP) to probe the velocity of a liquid near a wall with a resolution of the order of 100 nm As an example of use, we have investigated the boundary condition of the liquid velocity during lubricated friction and studied the influence of a classical additive (stearic acid) in a base oil (hexadecane), and demonstrate that simple Newtonian fluids can develop slip at the wallread more

TL;DR: A review of recent experimental, numerical and theoretical investigations on the subject can be found in this article, where the authors present a complex behavior at a liquid/solid interface involving an interplay of many physico-chemical parameters, including wetting, shear rate, pressure, surface charge, surface roughness, impurities and dissolved gas.

The friction and lubrication of solids
Frank Philip Bowden,David Tabor +1 more
TL;DR: Tabor and Bowden as mentioned in this paper reviewed the many advances made in this field during the past 36 years and outlined the achievements of Frank Philip Bowden, and reviewed the behavior of non-metals, especially elastomers; elastohydrodynamic lubrication; and the wear of sliding surfaces.

A general boundary condition for liquid flow at solid surfaces
TL;DR: In this paper, the authors present results from molecular dynamics simulations of newtonian liquids under shear which indicate that there exists a general nonlinear relationship between the amount of slip and the local shear rate at a solid surface.

Motions and relaxations of confined liquids
TL;DR: When a liquid is confined in a narrow gap, the effective shear viscosity is enhanced compared to the bulk, relaxation times are prolonged, and nonlinear responses set in at lower shear rates.

Shear flow near solids: Epitaxial order and flow boundary conditions.
TL;DR: In this article, the authors report on molecular-dynamics simulations of Lennard-Jones liquids sheared between two solid walls and show that the degree of slip is directly related to the amount of structure induced in the fluid by the periodic potential from the solid walls.

UV/ozone cleaning of surfaces
TL;DR: The ultraviolet (UV)/ozone surface cleaning method is reviewed in this article, which is an effective method of removing a variety of contaminants from surfaces and can rapidly produce clean surfaces, in air or in a vacuum system, at ambient temperatures.
