Synthesis, characterization and comparative study of Zn, Fe, and Cu MOFs-impregnated polysulfone mixed-matrix membranes for CO
Article in Scientific reports, 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
Decarbonization from fossil-combusted flue gas is crucial for recovering carbon sources and mitigating global warming risks. Composite membranes made of polysulfone (PSF) were created by doping Fe, Cu, and Zn metal-organic frameworks (MOFs). Synthesized MOF nanomaterials and membranes were characterized using advanced techniques to assess their structural, crystalline, morphological, thermal and decarbonization properties. Chemical characteristics of materials assessed through FTIR spectroscopy corroborated formation of MOFs nanocrystals. Crystalline phases of prepared MOF-based materials were established by XRD patterns. SEM-EDX micrographs indicated decent surface topography, uniform nanofiller distribution and compatible filler-matrix adhesion. Characteristic temperatures and improved thermal stability of membranes were inferred by TGA thermograms. Decarbonization efficiency of produced membranes determined by single- and mixed-gas permeation experiments using Gas Permeation rig indicated CO
