Swimming droplet in 1D geometries, an active Bretherton problem
Charlotte de Blois, Vincent Bertin, Saori Suda +3
We investigate experimentally the behavior of self-propelled water-in-oil droplets, confined in capillaries of different square and circular cross-sections. The droplet's activity…
Capillary Levelling of Immiscible Bilayer Films
Vincent Bertin, Carmen Lee, Thomas Salez +2
Flow in thin films is highly dependent on the boundary conditions. Here, we study the capillary levelling of thin bilayer films composed of two immiscible liquids. Specifically, a…
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…
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…
