Inside Cover: Ensemble Measurement of Diffusion: Novel Beauty and Evidence (ChemPhysChem 15/2009)
With interference microscopy and infrared micro-imaging, recently introduced into the investigation of mass transfer phenomena in nanoporous materials, unprecedented details on molecular diffusion are accessible, as shown by J. Kärger et al. on p. 2623. The picture shows the evolution of intracrystalline guest concentration after a pressure step in the surrounding atmosphere.
