Stop-go-left-right: Nature Communications on Drop Trapping and Steering

Electrically tunable wetting defects enable a detailed study of the interaction of sliding drop on inclined planes with heterogeneities on the surface. Analysis in terms of the dynamics of the center of mass in one dimension shows that the trapping is governed by two non-dimensional parameters, namely the strength of the defect normalized by the driving force and the ratio between an inertial and a viscous time scale in the system. The research was published in Nature Communications,
