Mechanochemical Degradation and Fluoride Recovery of Perfluorosulfonic Acid Polymer Membrane.
Article in ChemSusChem, 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
Per- or polyfluoroalkyl substances (PFAS) represent a large family of chemicals, widely used due to their outstanding properties. However, also known as "Forever Chemicals", they are raising attention due to high health and environmental risks. In last years, the elimination, degradation, or recycling of PFAS has become essential. In this work, the degradation of a perfluorosulfonic acid polymer, Nafion, composed of a poly(tetrafluoroethylene) backbone with perfluoroether side chains terminated by sulfonic acid groups, is studied. More precisely, the mechanochemical degradation, previously described for linear fluoropolymers, is reported on branched PFSA polymers in the presence of various activators (such as (pyro)phosphates, 1,8-Diazabicyclo [5.4.0]undec-7-ene (DBU), 1,5,7-Triazabicyclo [4.4.0]dec-5-ene(TBD), KOH) at room temperature. Recovered products were characterized over time by nuclear magnetic resonance and Fourier transformation infrared spectroscopy, scanning electron microscopy-energy dispersive X-ray spectroscopy, and liquid chromatography-mass spectrometry in order to both identify the released products and suggest a degradation pathway. The use of potassium hydroxide, although resulting in a moderate potassium fluoride yield, allowed the determination of fragments produced during the degradation mechanism, while others were ineffective. Phosphate salts have been revealed to be the best candidates enabling the mineralization of PFSA, yielding valuable products and a good fluorine recovery for a further circular economy.
