摘要: Diffusion in nanoporous host-guest systems is often considered to be too complicated comply with such "simple" relationships as Fick's first and second law of diffusion. However, it shown herein that the microscopic techniques diffusion measurement, notably pulsed field gradient (PFG) technique NMR spectroscopy microimaging by interference microscopy (IFM) IR (IRM), provide direct experimental evidence applicability laws systems. This remains true many situations, even when detailed mechanism complex. The limitations model are also discussed reference extensive literature on this subject.
