Sulfur-mediated transformation from osmium nanocrystals to single atoms for efficient alkaline hydrogen evolution reaction.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Osmium (Os)-based catalysts, recognized for their unique chemical and electronic properties along with cost-effectiveness, hold great potential for the hydrogen evolution reaction (HER). However, their practical application has long been limited because pure Os exhibits excessively strong adsorption of intermediates and suffers from stability issues. Herein, we report the development of a highly stable catalyst achieved by implanting the sulfur (S) atom into the matrix, facilitating the transformation of Os nanocrystals into Os single atoms. The prepared atomically dispersed Os catalyst (Os-SA@SNC) demonstrates outstanding catalytic activity, requiring only a 13 mV overpotential to achieve a current density of 10 mA cm
