Green Synthesis of Nitrogen-Doped Carbon Dots from Fresh Tea Leaves for Selective Fe
Article in Nanomaterials (Basel, Switzerland), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
In this research, we successfully developed a green, economical and effective one-step hydrothermal method for the synthesis of fluorescent nitrogen-doped carbon dots (N-CDs) by utilizing fresh tea leaves and urea as the carbon and nitrogen sources, respectively. The obtained N-CDs were characterized by TEM, XPS and FT-IR. We found that the N-CDs were near-spherical with an average size of about 2.32 nm, and contained abundant oxygen and nitrogen functional groups. The N-CDs exhibited bright blue fluorescence under ultraviolet illumination, with the maximum emission at 455 nm. Meanwhile, the as-prepared N-CDs could be selectively quenched by Fe
