Experimental progress in the pulsed field gradient technique of NMR and introduction of interference microscopy and IR micro-imaging are used to probe the transport properties of nanoporous materials. The accessible diffusion path lengths are shown to cover the range of particular relevance for the technological applications of these materials in heterogeneous catalysis, adsorption and separation.
