  Various group photos 2010-2020

The group transport in permeable media of department of applied physics of Eindhoven University of Technology focuses mainly on the study of moisture, ions transport and phase changes in technological porous materials, e.g., fired-clay brick, mortar, sludge, concrete and clay. For the measurement of the transport in porous media various specialized NMR scanners are used.
