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

Hydrogen boride (HB) nanosheets are emerging hydrogen-rich materials with controllable hydrogen-release properties under UV, electrochemical, and thermal stimuli. However, their practical application in high-temperature environments and harsh conditions, such as neutron shielding, requires improved stability against heat and light exposure. Herein, the synthesis of pyrazine-incorporated HB nanosheets (Pyrazine-HB) is reported via a simple solution-mixing and drying process. Despite a low pyrazine content of ≈2.9 mol%, Pyrazine-HB exhibits significantly enhanced thermal stability, with a hydrogen release temperature ≈200 K higher than that of pure HB. Moreover, its hydrogen release under UV and visible light irradiation is markedly suppressed. Brunauer-Emmett-Teller analysis reveals an increased surface area upon pyrazine incorporation, suggesting intercalation between HB layers. This is further supported by transmission electron microscopy, which showed changes in interlayer spacing indicative of molecular intercalation. The improved stability of Pyrazine-HB is attributed to expanded interlayer spacing, which prevents interlayer hydrogen recombination. This study presents a facile and effective molecular-level strategy for tuning the thermal stability and photostability of HB nanosheets, thereby advancing their potential for energy-related applications.
