Research Interests
|
|
The keyword is the behaviour of fluids at nano-scale. I study the transfers of ions and water molecules through nano-metric (tens of nanometers) barrier layers of composite nanofiltration membranes. The latter are used, for example, to remove hardness from seawater, which works very well but it is not, yet, really clear why. Another example is the transfer of ions and water through nano-porous track-etched membranes, which have identical straight cylindrical pores. They are very good for the studies of fundamentals of nano-fluidics.
I also study theoretically and experimentally the processes of current-induced concentration polarization of nano-/micro-interfaces. Here, the concentration-polarization phenomena are strongly-coupled to electroosmotic circulation. This gives rise to the appearance of desalination “shocks” moving away from the polarized interface, which can be useful for the pre-concentration of charged analytes via electrical stacking in micro-analytical systems.
