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

Borophene and silicene, two novel members of the Xene family, feature high surface reactivity and stability suitable for sensing applications. However, the gas sensing capabilities of these materials in their pristine form have not been systematically investigated. Here we show that borophene- and silicene-based quartz crystal microbalance (QCM) sensors achieve stable and sensitive relative humidity detection and we model their adsorption-desorption mechanisms. Borophene and silicene nanosheets were synthesized via liquid-phase exfoliation and characterized by transmission electron microscopy (TEM), X-ray photoelectron spectroscopy, and Brunauer-Emmett-Teller surface area analysis. The QCM sensors exhibited sensitivities of 3.2 Hz/%RH and 3.9 Hz/%RH, response/recovery times of 122/65 s and 47/130 s and hysteresis of 1.8% and 3.8% hysteresis for borophene and silicene, respectively. The dominant sensing mechanism was determined to be chemisorption, supported by thermodynamic modeling. These results suggest that 2D borophene and silicene can significantly contribute to sensing applications, especially in environments requiring air stability.
