Ion-engine hydrogel based solar desalination for water-electricity cogeneration with milliampere level current.
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
Seawater evaporation-induced electricity generation (SEG) holds potential in alleviating global energy and freshwater demands. However, conventional SEGs suffer from non-selective ion transport in seawater, leading to severe Debye screening effect and low output current (<10 µA). To overcome this bottleneck, we develop an ion-engine hydrogel based solar-powered SEG (SSEG), achieving milliampere level peak current of 1.2 mA from seawater due to molecular-level ion control, surpassing previously reported SEGs by 1 to 2 orders of magnitude. Molecular dynamics simulations and Hittorf's method confirm that the hydrogel dramatically enhances anion transference number (~0.83) while suppresses cation-induced Debye screening via chemical gating, which is attributed to synergistic effect of metal-polymer coordination and ion-preferential association. The integrated SSEG system operating outdoors can generate power up to 24 mW, sufficient to charge small electronics, while producing freshwater at a high-yield over 2.0 kg m
