The group transport in permeable media of department of applied physics Eindhoven focuses mainly on the study of 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 NMR scanners are used.

    Announcement: Cryspom III  will be from 4-7 sept 2012 in Tróia Portugal (offical website)
