Revealing Phase-Dependent Catalytic Behavior of Ru Nanoparticles via Operando TEM.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The crystal phase of metal nanocatalysts plays a critical role in determining their catalytic performance, yet the atomic-scale mechanisms underlying their phase-dependent reactivity remain poorly understood. Here, using operando gas-cell transmission electron microscopy (TEM), we directly correlate the crystal structures of Ru nanoparticles (NPs) with their catalytic behavior during CO oxidation. We find that face-centered cubic (fcc) Ru exhibits high catalytic activity and structural stability, whereas hexagonal close-packed (hcp) Ru deactivates rapidly because of its pronounced susceptibility to oxidation. Furthermore, the transformation of fcc Ru NPs to hcp phase results in a marked loss of catalytic activity, underscoring the detrimental impact of phase instability under reaction conditions. These findings highlight the importance of direct observation of catalysts in reactive environments and provide mechanistic insights crucial for the rational design of phase-engineered nanocatalysts.
