Interplay between hydrophilicity and surface barriers on water transport in zeolite membranes
Open accessAbstract
A comprehensive understanding of molecular transport within nanoporous materials remains elusive in a broad variety of engineering and biomedical applications. Here, experiments and atomistic simulations are synergically used to elucidate the non-trivial interplay between nanopore hydrophilicity and surface barriers on the overall water transport through zeolite crystals. At these nanometre-length scales, these results highlight the dominating effect of surface imperfections with reduced permeability on the overall water transport. A simple diffusion resistance model is shown to be sufficient to capture the effects of both intracrystalline and surface diffusion resistances, thus properly linking simulation to experimental evidence. This work suggests that future experimental work should focus on eliminating/overcoming these surface imperfections, which promise an order of magnitude improvement in permeability.

The interaction between BAS zeolites and water governs water mobility and clustering in zeolite pores.
“(iii) water mobility and clustering in zeolite pores10”
From A reactive neural network framework for water-loaded acidic zeolites (2024) · cites this paper as [10]
The Results section (‘Intracrystalline diffusion in zeolites’; page not specified) reports that water–zeolite interactions affect water mobility in MFI pores at low hydration, while water–water interactions predominate at higher hydration. It examines water–water hydrogen bonds but does not establish that Brønsted acid sites govern water clustering. (LLM, conf=0.86)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
