Capillary-Induced Motion of Particles Bridging Interfaces of a Free-Standing Thin Liquid Film

We demonstrate a new form of capillary force experienced by neutrally buoyant spherical particles adsorbed simultaneously at both interfaces of a thin liquid film of spatially varying thickness. The force is proportional to the slope of the interface and the difference between the local contact angl...
