Nanoporous solids are ubiquitous in chemical, energy, and environmental processes, where
controlled transport of molecules through the pores plays a crucial role. They are used as …

The apparent tortuosity due to adsorption of diffusing tracers in a porous material is
determined by a scaling approach and is used to analyze recent data on LiCl and alkane …

We consider an overdamped Brownian particle subject to an asymptotically flat potential
with a trap of depth U 0 around the origin. When the temperature is small compared to the …

The adsorption-desorption phenomena play a pivotal role in several industrial and scientific
processes, deserving attention from research groups across several fields of knowledge. In …

Anomalous diffusion of an antibiotic (colistin) in a system consisting of packed gel (alginate)
beads immersed in water is studied experimentally and theoretically. The experimental …

The interplay of tracer adsorption, pore bulk diffusion, and surface diffusion is studied in
asimple membrane model with parallel pores, porosity ε, and specific surface area s. For …
