Nanoscale Degradation Study of a Commercial Pt-Co/C Fuel-Cell Electrocatalyst at Elevated Temperature Utilizing Identical-Location Scanning Transmission Electron Microscopy.
Article in The journal of physical chemistry. C, Nanomaterials and interfaces, 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
Understanding the degradation mechanisms of Pt-based alloy electrocatalysts under realistic operating conditions, such as elevated temperature, is essential for improving the durability of proton exchange membrane fuel cells (PEMFCs). This study investigates the degradation behavior of a commercial PEMFC Pt-Co/C electrocatalyst on the individual nanoparticle scale, employing identical location scanning transmission electron microscopy (IL-STEM), in combination with electrochemical methods. The catalyst was subjected to the modified US Department of Energy protocol at an elevated temperature (fast potential cycling between 0.6 and 0.95 V
