Superharmonic proton motion in high-energy-density organic electrodes for aqueous zinc batteries.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 limited proton transfer kinetics within organic positive electrodes restricts the proton storage capacity and hinders achieving high energy density in aqueous zinc-organic batteries. Herein, we obtain superharmonic motion of proton by crosslinking short hydrogen-bonds network within the positive electrode matrix to achieve fast proton transfer. Specifically, the pyrazino[2, 3-g]quinoxaline-5, 10-dione owing strong electrostatic and hydrogen-bond interactions with hydrogen ions is synthesized, which could attract concentrated hydronium and trigger local proton enrichment. Spatially confined water-hydronium domains are therefore formed to generate short hydrogen bonds around pyrazino[2, 3-g]quinoxaline-5, 10-dione molecules. Moreover, the 4,4'-diaminodiphenylamine and polytetrafluoroethylene binder exhibits a mutual affinity with pyrazino[2, 3-g]quinoxaline-5, 10-dione due to the strong hydrogen-bond interactions of them, which reduce the intermolecular distance within positive electrode and construct a highly interconnected state of water-hydronium domains, thereby establishing the short hydrogen bonds network throughout the electrode matrix. The rapid proton transport through short hydrogen bonds consequently reduces the polarization of aqueous zinc-organic batteries (1.47 × 10
