High-fidelity electrical detection of spin transport in graphene.
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
Graphene can support spin transport over long distances, yet achieving large electrical spin signals remains challenging because spin injection and detection are highly sensitive to disorder at tunnel-barrier interfaces. Here we demonstrate that suppressing such interfacial disorder enables high-fidelity spin injection and detection in graphene. We fabricate van der Waals graphene spin valves by exfoliating and assembling constituent two-dimensional crystals inside an inert glovebox, combined with contamination-suppressing lamination and thorough post-transfer cleaning to realize atomically flat hexagonal boron nitride tunnel barriers. Our four-terminal nonlocal devices exhibit exceptionally large spin polarizations approaching 90 percent and nonlocal spin signals up to 1.6 kΩ. The high tunnel-barrier quality enables robust spin detection down to nanoampere excitation currents and gate-tunable magnetoresistance exceeding 80 percent. Spin precession measurements reveal Elliott-Yafet-type relaxation with nearly isotropic spin dynamics. These results establish interface-controlled van der Waals fabrication as an effective route to high-signal spin transport in graphene.
