Title: | Diffusion of Interacting Particles in Discrete Geometries | Authors: | BECKER, Thijs NELISSEN, Kwinten CLEUREN, Bart PARTOENS, Bart VAN DEN BROECK, Christian |
Issue Date: | 2013 | Source: | PHYSICAL REVIEW LETTERS, 111 (11) | Abstract: | We evaluate the self-diffusion and transport diffusion of interacting particles in a discrete geometry consisting of a linear chain of cavities, with interactions within a cavity described by a free-energy function. Exact analytical expressions are obtained in the absence of correlations, showing that the self- diffusion can exceed the transport diffusion if the free-energy function is concave. The effect of correlations is elucidated by comparison with numerical results. Quantitative agreement is obtained with recent experimental data for diffusion in a nanoporous zeolitic imidazolate framework material, ZIF-8. | Notes: | [Becker, T.; Nelissen, K.; Cleuren, B.; Van den Broeck, C.] Hasselt Univ, B-3590 Diepenbeek, Belgium.
