An aqueous electrohydrodynamic (EHD) floating liquid bridge is a unique environment for studying the influence of protonic currents (mA cm

Phys Rev E Stat Nonlin Soft Matter Phys. 2015 Sep;92(3):031003. doi: 10.1103/PhysRevE.92.031003. Epub 2015 Sep 08.

We investigate the coupled dynamics of the local hydrodynamics and global electric response of an electrodialysis system, which consists of an electrolyte solution adjacent to a charge selective membrane under electric forcing. Under a dc electric current, counterions transport...

Confined Electroconvective Vortices at Structured Ion Exchange Membranes.

Langmuir. 2018 Feb 20;34(7):2455-2463. doi: 10.1021/acs.langmuir.7b04135. Epub 2018 Feb 05.

In this paper, we investigate electroconvective ion transport at cation exchange membranes with different geometry square-wave structures (line undulations) experimentally and numerically. Electroconvective microvortices are induced by strong concentration polarization once a threshold potential difference is applied. The applied...

Visualizing the hydrodynamics in sieve-based lateral displacement systems.

Sci Rep. 2018 Aug 27;8(1):12861. doi: 10.1038/s41598-018-31104-2.

Deterministic lateral displacement (DLD) systems structure suspension flow in so called flow lanes. The width of these flow lanes is crucial for separation of particles and determines whether particles with certain size are displaced or not. In previous research,...
