Droplet Migration on Conical Fibers
Clementine Fournier, Carmen Lee, Rafael Schulman +2
The spontaneous migration of droplets on conical fibers is studied experimentally by depositing silicone oil droplets onto conical glass fibers. Their motion is recorded using opti…
Nonlinear amplification of adhesion forces in interleaved books
Raphaelle Taub, Thomas Salez, Hector Alarcon +3
Two interleaved phonebooks are nearly impossible to separate by pulling their spines. The very slight force exerted by the outer sheets of the assembly is amplified as the exponent…
Symmetrization of Thin Free-Standing Liquid Films via Capillary-Driven Flow
Vincent Bertin, John Niven, Howard A. Stone +3
We present experiments to study the relaxation of a nano-scale cylindrical perturbation at one of the two interfaces of a thin viscous free-standing polymeric film. Driven by capil…
Cooperative strings and glassy dynamics in various confined geometries
Maxence Arutkin, Elie Raphaël, James Forrest +1
Previously, we developed a minimal model based on random cooperative strings for the relaxation of supercooled liquids in the bulk and near free interfaces, and we recovered some k…
Rearrangement of 2D aggregates of droplets under compression: signatures of the energy landscape from crystal to glass
Jean-Christophe Ono-dit-Biot, Pierre Soulard, Solomon Barkley +4
We study signatures of the energy landscape's evolution through the crystal-to-glass transition by compressing 2D finite aggregates of oil droplets. Droplets of two distinct sizes…
Direct Measurement of the Elastohydrodynamic Lift Force at the Nanoscale
Zaicheng Zhang, Vincent Bertin, Muhammad Arshad +3
We present the first direct measurement of the elastohydrodynamic lift force acting on a sphere moving within a viscous liquid, near and along a soft substrate under nanometric con…
