**About the Editors**

**Victor V. Nikonenko** Professor of Physical Chemistry at the Kuban State University, Krasnodar, Russia.

Victor Nikonenko graduated from the Mathematical Faculty of the Kuban State University; defended his Doctor of science thesis at the A.N. Frumkin Institute of Electrochemistry of Russian Academy of Sciences (1996) and his HDR thesis at the Paris-Est University (2001). He is working in the field of transport phenomena in membrane systems including 'membrane structure - properties' relationships, coupling between ion and water transport as well as coupling between ion/molecule transport and chemical reactions. He is Russian co-director of the French-Russian International Associated Laboratory "Ion-exchange membranes and related processes". Member of the editorial board of "Russian Journal of Electrochemistry" and "Membranes and Membrane Technologies" journal (published in Russian and English). Member of the editorial board and guest editor of the "International Journal of Molecular Sciences" (MDPI) journal and "Membranes" (MDPI) journal. Doctor Honoris Causa at the University of Montpellier, France; associated professor at the Laval University, Quebec, Canada. ´

**Natalia D. Pismenskaya** Professor of Physical Chemistry at the Kuban State University, Krasnodar, Russia.

Natalia Pismenskaya graduated from the Chemical Faculty of the Kuban State University; defended her Ph. D. thesis (1989) at the Kuban Polytechnic State University and her Doctor of Science thesis (2004) at the Kuban State University. She is working in the field of ion-exchange membranes and processes; transport phenomena in membrane systems; concentration polarization and coupled phenomena of concentration polarization (water splitting, electroconvection, gravitation convection, etc.); chemical reactions coupled with ions transfer; fouling; ion exchange membrane modification and characterization; experimental techniques for the investigation of membrane system.
