Electrowetting-Induced Oil Film Entrapment and Instability [PDF]
Physical Review Letters, 2006 We investigate the spreading at variable rate of a water drop on a smooth hydrophobic substrate in an ambient oil bath driven by electrowetting. We find that a thin film of oil is entrapped under the drop. Its thickness is described by an extension of the Landau-Levich law of dip coating that includes the electrostatic pressure contribution.

Oil Film Formation of Reciprocating Seals Observed by Interferometry
Tribology Online, 2014 Oil film thickness in rubber piston seals is measured by interferometry. Optimized optics and fluids enable clear interferograms. The oil film thickness on the contact area is measured during reciprocating motion.

Study of Flow between Non-Isothermal Disks in Hydro-Viscous Drive
Tribology Online, 2018 The film flow between the disks is the critical factor in the design of hydro-viscous drive. In the previous work dealing with the flow in the gap, few authors considered the effect of non-isothermal interface on the flow.

Diffusion of Oil Films over Insects [PDF]
Nature, 1962 CONTACT insecticides are often formulated as solutions in oil and presented as deposits sprayed on to surfaces. The spread of oil on to insects walking over superficial films is an essential process in the action of such a deposit, though the quantities of oil involved are extremely small.
