Diffusion, that is, the Brownian motion of guest molecules, is often decisive in the performance of nanoporous host materials in their technological applications. In general, different techniques with differing length scales of observation yield notably differing diffusivities as a consequence of the existence of additional transport resistances acting in addition to the diffusional resistance of the pore space. These resistances are avoided in specially prepared nanoporous glasses, yielding coinciding diffusivities in macroscopic and microscopic measurements, as shown by J. Kärger et al. on p. 1130.
