Superior microwave shielding modulation based on rapidly prepared graphene metasurface.
Article in National science review, 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
Active manipulation of electromagnetic wave jamming is a critical challenge for next-generation adaptive electronics. Electrical conductivity-tunable porous materials have been developed, but have encountered the challenge of constrained modulation range and large thickness. Herein, we report a method for modulating the shielding efficiency of microwaves based on a micrometer-thick graphene metasurface. The continuous modulation between wave transmission and shielding in an ultra-wide range of 9.66%-99.78% is achieved, due to the remarkable anisotropy of wave-induced electron oscillation. By rotating the metasurface, wherein alignment of the periodically arranged graphene strips with the incident electric field enhances electron oscillations and boosts secondary radiation, significantly improved shielding efficiency is obtained. Notably, the metasurface achieves facile preparation and open-air processability utilizing laser-induced ultrafast kinetics, facilitating its application in advanced smart electromagnetic devices. Finally, we demonstrate its potential in a novel paradigm for data electromagnetic encryption.
