Probing charge-transfer processes in Pt/TiO
Article in Proceedings of the National Academy of Sciences of the United States of America, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Electrocatalysts in combination with photoelectrodes can provide higher activity and/or lower overpotential for a broad range of photoelectrochemical processes. Although cocatalyst nanoparticles (NPs) on semiconductor surfaces have been extensively studied, spatially resolved kinetic measurements of charge-transfer processes in such systems remain challenging. Here, we introduce a unique approach based on a single setup employing contact amperometric/potentiometric photo-scanning electrochemical microscopy for quantitative, high-resolution measurements of photoelectrochemical processes in nanostructured photocatalysts. Amperometric SECM experiments are coupled with nanoscale local potential measurements made using the same nanotip, which is brought within the tunneling distance from the sample surface.
