Of course, the area of research connected with interface transport phenomena is still at its infancy. Thus, the role of surface conductance just started to be probed. Besides that, many assumptions exploited above should obviously be relaxed. For example, in the future, we suggest as a fruitful direction to consider electro-osmotic flow in a thin gap and to assume a partial slip at the gas sectors. It will be very important to investigate transverse electrokinetic phenomena, which could be greatly amplified by using striped superhydrophobic surfaces. Note that if the charge is varied along the direction of the electric field, the fluid close to a superhydrophobic wall is pulled periodically in opposite directions. As a result, the recirculation rolls should develop on a scale proportional to the texture size, L. This should provide an additional opportunity for mixing, similar to that described in but hopefully much faster.
