Strain-Induced Electrical Conductivity in Diamond Nanowires.
Article in Nano letters, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
At the nanoscale, a highly insulating ultrawide-bandgap diamond turns from a hard but brittle bulk solid into highly elastic rods and wires. It has been predicted that such an elasticity change would be sufficient to increase conductivity and narrow the bandgap, enabling metallization of diamond at the nanoscale, making it suitable for nanoscale applications. In this work, we experimentally demonstrate that applying a mechanical load by using an atomic force microscopy cantilever increases conductivity in diamond nanowires. Mechanical properties are tested via a micromanipulator inside the scanning electron microscope, and nanowires show a high bending angle of 39°, before fracture, indicating their elasticity. Furthermore, finite element method simulations suggest that the strain in the central region of the nanowire with maximum vertical displacement is sufficient for metallization in nanowires. Our findings provide direct evidence of the strain-induced conductance in diamond nanowires, pivotal for durable quantum electronics and biomedical applications.
