Giant Slip at Liquid-Liquid Interfaces Using Hydrophobic Ball Bearings
Q Ehlinger and L Joly and O Pierre-Louis, PHYSICAL REVIEW LETTERS, 110, 104504 (2013).
Liquid-gas-liquid interfaces stabilized by hydrophobic beads behave as ball bearings under shear and exhibit a giant slip. Using a scaling analysis and molecular dynamics simulations we predict that, when the contact angle theta between the beads and the liquid is large, the slip length diverges as R rho(-1) (pi -theta)(-3) where R is the bead radius, and theta is the bead density.
