Resistances along the CO2 diffusion pathway inside leaves [PDF]
Journal of Experimental Botany, 2009 CO(2) faces a series of resistances while diffusing between the substomatal cavities and the sites of carboxylation within chloroplasts. The absence of techniques to measure the resistance of individual steps makes it difficult to define their relative importance.

Study on the Adsorption, Diffusion and Permeation Selectivity of Shale Gas in Organics
Energies, 2017 As kerogen is the main organic component in shale, the adsorption capacity, diffusion and permeability of the gas in kerogen plays an important role in shale gas production. Based on the molecular model of type II kerogen, an organic nanoporous structure
