Spin-Split Edge States in Metal-Supported Graphene Nanoislands Obtained by CVD.
Article in Advanced materials (Deerfield Beach, Fla.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Spin-split states localized on zigzag edges have been predicted for different free-standing graphene nanostructures. However, the stability of the edge magnetism can be severely compromised by interfacial interactions when supported on metallic substrates. This imposes a serious challenge for the surface-assisted synthesis and characterization of magnetic graphene nanostructures, and their application in metal supports. In this work we demonstrate that graphene nanoislands with well-defined zigzag edges, synthesized by ultra-high vacuum chemical vapour deposition, can retrieve their spin-split edge states by minimizing interfacial interactions through metal intercalation. Using scanning tunneling microscopy and spectroscopy we detect edge states with subnanometer spatial localization and 1.2 eV energy splitting, comparable to the spin-polarized states predicted by ab-initio calculations. The fabrication of magnetic nanographenes by CVD opens a new avenue for the fabrication of 2D nanostructures that cannot be achieved by on-surface synthesis, and enables the implementation of demonstrated processes for scaling up synthesis.
