In order to participate in the seminar, a few minutes prior to the beginning of the seminar you should connect to the Zoom conference via the following link or manually using the Zoom conference ID 897 7646 2466 and password 549526. If you have problems logging into Zoom, you can connect to the YouTube livestream of the seminarThe transfer of charged particle-ions in electrolyte solutions is a fundamental object of research in modern physical chemistry and electrochemistry. In our report, we will focus on one of the most interesting and difficult situations — the transfer of ions across a surface separating a liquid electrolyte and a charged solid (for example, an electrode or a polymer membrane). In this case, the leading characteristics and parameters of the phenomenon under study depend on physicochemical processes occurring on a wide range of spatial scales — from interatomic distances (nanometers) to macroscopic scales (millimeters and centimeters). In recent decades, this area of ​​electrochemistry and related applied mathematical research have acquired particular importance in connection with the rapid development of nanotechnology and, in particular, micro- and nano-fluidics, — a sub-area of ​​nanotechnology that studies the processes of fluid flow and related processes. transfer in micro- and nano-channels.
