Looking into the crystallites: diffusion studies by interference microscopy
Application of Interference Microscopy to monitor transient concentration profiles in nanoporous crystals is shown to provide a unique and unprecedented option for exploring their transport properties. We present three most recent implementations of this technique, namely the discovery of one-dimensional diffusion following the patterns of site-to-site hopping in MOF manganese formate, the exploration of diffusivities in the two-dimensional channel network of Ferrierite over two orders of magnitude and the direct diffusion measurement in the three principal directions of zeolite STA-7. Special emphasis is given on the problem-related procedure for deducing the relevant micro-physical information from the primary data.
