Transport of penetrants in the macromolecular structure of coals. i. anomalous transport in untreated and pyridine-extracted coals
Nicholas A. Peppas,Lucy M. Lucht +1 more
TL;DR: In this paper, the authors investigated the mechanisms of penetrant transport in coal sections and particles and observed anomalous (non-Fickian) and Case-II transport were observed in much the same way as with glassy polymers.

Transport of penetrants in the macromolecular structure of coals III. Dynamic swelling of stiff polymer networks that simulate the coal structure
TL;DR: In this paper, the structure of three cross-linked polymers containing naphthalenic rings in their backbone structure was investigated by dynamic swelling and thermal analytic techniques, and it was determined that the pyridine and n-proplyamine transport in microparticles (40 μm) of these polymers was non-Fickian, often approaching case II transport and sometimes even supercase II transport.
