Best paper of 2011 in EuroPhysics Letters

The article “Electric field-driven instability on superhydrophobic surfaces” by Jung Min Oh et al. has been selected for the collection of best publications in 2011 in EuroPhysics Letters. The publication describes the physical principles governing the switching of topographically structured surfaces from the superhydrophobic Cassie state to the conventional Wenzel wetting state using electrodes embedded on the substrate below the surface pattern. This work is part of the general research line on electrically switchable smart surfaces in the Physics of Complex Fluids group with various applications in microfluidics and optofluidics.
