Radiation detector based on coupling between defect mode and topological edge state mode in photonic crystal.
Article in Scientific reports, 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
Symmetrical one-dimensional photonic crystal structure with polymer nanocomposite materials is introduced as the basis for an extremely sensitive and accurate gamma radiation sensor. The architecture of the sensor makes use of the interaction between a defect mode and a topological edge state to provide remarkable optical performance when exposed to gamma radiation. In response to changing gamma dosages, the transmittance spectra show a noticeable wavelength change and a highly accurate linear correlation. Key performance parameters of the sensor include a sensitivity of 0.2267 nm/RIU and quality factor of 447,747.5. These measurements highlight the sensor's exceptional stability and resolution in detecting even the smallest variations in gamma radiation dosages. With potential uses in industrial, environmental, and medical monitoring, the suggested sensor is a breakthrough in radiation detection. In future work, we aim to enhance sensitivity and utilize more stable materials to improve performance under high radiation doses.
