Metal-organic framework membranes with scale-like structure for efficient propylene/propane separation.
Article in Nature communications, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
The fabrication of metal-organic framework (MOF) membranes with high propylene/propane selectivity, high mechanical endurance and ease of scaling up always remains a challenge. Inspired by the ubiquitous biological wear-resistant structure, here we show ZIF-67 membranes with a tangential-normal interlaced structure (TN-ZIF-67) for one-step acquisition of polymer-grade propylene, which is endowed with the merits of intergranular defect elimination, partial ZIF-67 lattice flexibility restriction and anti-wear of the membrane surface. The TN-ZIF-67 membrane exhibits an optimal propylene/propane mixture separation factor of 221, and the separation performance remained unchanged after 1.5 years of storage or abrasion by repeated sanding. The distinctive membrane structure can be further scaled up on 4 mm-diameter tubular substrates. This work demonstrates a strategy to extend the rational design of defect-free, anti-wear MOF membranes with superior separation performance and stability that could fulfill future industrial applications.
