Fabrication of carbon-coated silicon nanowires for photoelectrochemical water splitting.
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
Carbon was deposited onto silicon nanowires (SiNWs) via pyrolysis to form a high-performance Carbon/SiNWs photocathode. Compared with pristine SiNWs, the carbon-modified photocathode exhibited substantially enhanced photoelectrochemical performance, achieving a photocurrent density of -13 mA·cm[Formula: see text] at 0 V vs RHE and an onset potential of 0.60 V vs RHE, indicating a 0.42 V positive shift relative to unmodified SiNWs. Electrochemical impedance spectroscopy indicated a reduction in charge transfer resistance ([Formula: see text]) from 1005 Ω (pristine) to 91 Ω (carbon-coated). These results demonstrate that carbon deposition is an effective strategy to enhance the photoelectrochemical performance of silicon-based photocathodes, offering direct relevance for solar energy conversion and water-splitting applications.
