The venerable theory of electrokinetic phenomena rests on the hypothesis of a dilute
solution of point-like ions in quasi-equilibrium with a weakly charged surface, whose …

Usually in electrochemical systems, the direct current densities not exceeding the limiting
current density are applied. However, the recent practice of electrodialysis evidences the …

For about 60 years, it is known that “limiting current” density does not really limit the current
density in electrodialysis (ED). The use of intensive currents allows one to decrease the area …

In this review, we tried to qualify different types and mechanisms of wall slip phenomenon,
paying particular attention to the most recent publications and issues. The review covers all …

Mechanisms for overlimiting current and concentration polarization in electrodialysis (ED)
with ion-exchange membranes are not yet well understood despite its half-century history. A …

Electroosmosis is a fascinating effect where liquid motion is induced by an applied electric
field. Counter ions accumulate in the vicinity of charged surfaces, triggering a coupling …

We discuss how the wettability and roughness of a solid impacts its hydrodynamic
properties. We see in particular that hydrophobic slippage can be dramatically affected by …

Colloidal particles in a liquid crystal (LC) behave very differently from their counterparts in
isotropic fluids. Elastic nature of the orientational order and surface anchoring of the director …

A super-hydrophobic array of grooves containing trapped gas (stripes) has the potential to
greatly reduce drag and enhance mixing phenomena in microfluidic devices. Recent work …

Devising effective methods to reduce drag forces is of great interest as these methods could
prevent the wastage of fuel and decrease carbon emission and the global warming rate …
