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

The intrinsic trade-off between hardness and toughness presents a long-standing challenge for diamond-based materials, limiting their use in extreme environments. Here, we report a bioinspired strategy to overcome this limitation by engineering graphite precursors with mimosa-like microscale curvature. Under high-pressure and high-temperature conditions (15 gigapascals and 2300 kelvin), these precursors concentrate local stress, promoting nucleation of hexagonal diamond within a cubic diamond matrix and forming cubic-hexagonal heterostructures. The resulting composites exhibit exceptional hardness (169 gigapascals) and toughness (15.7 megapascals multiplied by square root of meter), representing 36 and 104% improvements over single-phase nanopolycrystalline diamond, respectively. This dual enhancement arises from stacking fault interlocking and semi/coherent boundaries that resist deformation, coupled with phase transformation and crack deflection that dissipate fracture energy. Our results demonstrate a microstructural design paradigm for mitigating the property trade-off in superhard materials and offer a scalable strategy for engineering robust diamond-based systems.
