Iontrovoltaic effect based on triboelectrically induced ion polarization at semiconductor-liquid interfaces.
Article in Nature communications, 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
Controlling interfacial energy levels at semiconductor-liquid interfaces is critical yet challenging because charge separation is dictated by coupled semiconductor band bending and electrical double layers. Existing chemical and electrical regulation strategies inevitably require invasive treatments or external energy input. Here, we propose an iontrovoltaic mechanism, in which asymmetric electrical double layers establish ionic concentration gradients driving ionic directional migration. Triboelectrically induced ionic polarization simultaneously modulates electrical double layers and semiconductor band bending, enhancing the coupled electrical double layer-space charge region field to promote photocarrier separation. Coupled interfacial oxidation and ionic migration enable efficient ionic-electronic transport in iontrovoltaic nanogenerators. Local pH mapping, Kelvin probe measurements, and Mott-Schottky analysis confirm coupled ionic redistribution and band modulation. Integrating alkaline oxidation and infrared photothermal activation yields redox-coupled iontrovoltaic nanogenerators with a peak power density of 541 W m
