1 · What the graph read from it

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.

2 · The registry

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

High-entropy alloy nanostructures (HEA-NSs) hold promise in advanced catalysis and materials science, but lack a robust and universal synthetic strategy designed at an atomic level. Here, femtosecond lasers are used to prepare HEA-NSs, from single atoms to 100 nm nanoparticles, either free-standing or supported on a variety of substrates. Ultrafast excitation enables precise control over electron dynamics and instantaneously formed solvated electrons induce rapid, nonselective ion reduction ∼100 picoseconds post-irradiation, followed by stochastic atom nucleation and formation of atomically dispersed HEA-NSs through diffusion-controlled dynamics beyond nanoseconds. These processes are governed by the spatiotemporal confinement effect (STCE), with atomic diffusion restricted within nanoseconds, thereby enabling kinetic trapping of metastable nanoclusters with strict atomic-level dispersity. As a demonstration, FeCoNiRuPt achieved a peak power density of 2.1 W cm
