Research in the SFI group is related to transport phenomena near boundaries. We are currently working along the following lines:

Interfacial flow phenomena

Interfacial flow phenomena

We explore the fluid flow characteristics at interfaces. These interfaces can be reactive, charged, or present heterogeneities. The interplay between the interface characteristics and resulting flow phenomena is explored.

Ion transport at interfaces

Ion transport at interfaces

The transport of ions at ion selective interfaces is crucial for many existing and upcoming separation processes. We explore the transport of ions through perforated graphene membranes, as well as fundamentals of ion transport in confined geometries.

Advanced separations

Advanced separations

We investigate and develop (catalytic) membrane processes for water treatment. Regarding the removal of organic contaminants, we explore (photo)catalytic active membranes as well as liquid infused membranes.
