Enhancing contact electrification using nanofluids during liquid intrusion and extrusion in nanoporous materials.
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
Solid-liquid triboelectrification is of paramount importance for a wide range of processes. In this study, we demonstrate that a small addition of nanoparticles into water significantly enhances contact electrification in both intrusion–extrusion and immersion–emersion processes. In particular, fullerenol nanoparticles were applied as an aqueous nanofluid to intrusion–extrusion triboelectric nanogenerators. The results demonstrated more than one order of magnitude increase in energy output during intrusion–extrusion using two nanoporous materials with distinct porosities, mesoporous silica WC8 and the microporous MOF ZIF-8. These results suggest that even a minor presence of solid particles in a liquid plays a significant role in the process of solid-liquid contact electrification. This paves the way for efficient solid-liquid triboelectric generators based on nanofluids instead of simple liquids.
