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

High electrical conductivity is crucial for electrics, electronics, communications. Eliminating defects such as grain boundaries and impurities is a primary approach to enhancing electrical conductivity in metals. Although reducing electron-phonon interaction can further contribute to electrical conductivity, only a marginal enhancement is obtained by imposing external pressure even high up to gigapascal. Here we report a contrary strategy to transforming defects into conductive benefits, by forming abundant defects of severely distorted lattice via heterogeneous interface-assisted plastic deformation in metal (copper). Such lattice distortions are generated under a non-extreme condition, and cause internal giant local stress significantly suppressing electron-phonon coupling and thus reducing phonon-caused electron scattering. Consequently, a striking bulk electrical conductivity of > 110% IACS is obtained in the copper at room temperature, which is equivalent to the effect of an external high pressure of about 10 gigapascals. Our work provides an extendable approach for developing high-performance metal conductors.
