Sulfur-Induced Shape Compliance Modulates Fe Catalyst Agglomeration in Carbon Nanotube Growth.
Article in Nano letters, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Large-scale carbon nanotube (CNT) synthesis based on floating catalyst chemical vapor deposition (FC-CVD), unlike conventional CVD, utilizes a growth promoter, commonly a sulfur-containing species, whose role in the overall growth process is still poorly understood, hindering more efficient reactor design and a better quality CNT product. By developing a machine-learning interatomic potential here, we conduct atomistic molecular dynamics collision simulations for pure Fe and Fe-S clusters that allow us to directly quantify their sticking probability. Sulfur is found to reduce the intrinsic sticking for small clusters, instead strongly enhancing it for larger sizes. We demonstrate that this crossover is driven by S-induced shape compliance, a mechanism where surface passivation leads to large shape fluctuations that efficiently absorb collision energy. These insights may help rationalize the diverse and sometimes conflicting experimental outcomes reported for S-assisted FC-CVD synthesis of CNTs.
