Effects of Pore Connectivity on Water Adsorption in Metal-Organic Frameworks.
Article in Langmuir : the ACS journal of surfaces and colloids, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Atmospheric water harvesting (AWH) has emerged as a promising solution to help address global freshwater scarcity. Metal-organic frameworks (MOFs) are premier adsorbent candidates for their highly tunable nature through combinations of metal nodes and organic linkers. Ideally, they should exhibit an "S-shaped" isotherm, featuring large water uptake that can be released within a narrow humidity range. While the effects of pore dimension and chemical affinity on their adsorption properties have been studied, the influence of spatial pore connectivity remains largely unexplored. To this end, this study investigates the role of topological connectivity in their water adsorption properties using flat-histogram Monte Carlo simulations. Specifically, two representative types of MOFs (i.e., one with connected cages and another with individual channels) are studied. Moreover, a strategic pore-blocking approach is employed to systematically modulate their structural connectivity without altering local host-adsorbate interactions. Simulation results show that enhanced spatial connectivity fundamentally promotes cooperative adsorption, notably shifting the step pressure toward a lower value. Grand potential free energy and configurational analyses further reveal that interconnected pores facilitate the formation of a more stable condensed phase with extended hydrogen-bonding networks. Interestingly, in MOFs with effectively isolated one-dimensional channels, minor interpore associative behaviors through long-range Coulombic interactions can still persist, exerting a non-negligible influence on their water adsorption behavior. Comparative simulations for nonpolar gases also confirm that this connectivity-driven step shift is a unique characteristic of strongly associated molecules like water. Overall, this work demonstrates that pore connectivity is a critical structural parameter dictating water phase behavior, offering key insights into the rational design of highly efficient AWH adsorbents.
