1 · What the graph read from it

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.

2 · The registry

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

Boron nitride nanotubes (BNNTs) are an emerging mid-infrared optical material that exhibits significant potential in nanoscale resonators, lasers, detectors, and sensors due to the strong light-matter interactions induced by phonon polaritons (PhPs). However, the large-scale controllable synthesis and device applications of BNNTs still face huge challenges. In this study, a substrate-pretreated and boron source dual-catalyst infiltrated growth method, and a damage-free purification method toward the high-density and aligned BNNT (ABNNT) thin films is developed. The polarization sensitivity and linear dichroism characteristics of BNNTs with a maximum anisotropy ratio of 4.53 in the mid-infrared and near-infrared regions are comprehensively verified. The nanotube-alignment induced permittivity anisotropy outside RB and the near-isotropic PhP absorption within RB enable a wavelength-selective polarizer and absorber throughout a broad infrared range. Uniquely, the BNNT polarizer exhibits excellent stability of polarization dichroism under severe bending conditions, demonstrating great potential in flexible and wearable optical devices. This work can initiate the utilization of high-density BNNT thin films in quantum information processing and high-resolution infrared imaging applications.
