Frictional Dissipation and Scaling Laws at van der Waals Interfaces: The Role of Edge and Corner Elastic Moiré Pinning.

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
van der Waals heterogeneous interfaces are promising candidates for the scaling-up of structural superlubricity to meet a wide range of applications. Several factors, however, have been identified that may hinder superlubricity. Elasticity is one such intrinsic factor, where shear induced lattice reconstruction leads to local interfacial pinning, even at clean pristine contacts. This introduces intricate energy dissipation mechanisms that are manifested by unconventional frictional scaling laws. Here, through large-scale atomistic simulations, we reveal that the elastic pinning of incomplete moiré tiles at the corners of polygonal sliders dominates kinetic friction up to contact dimensions of hundreds of nanometers, followed by a crossover to edge, and eventually surface dominated frictional regimes. We further demonstrate that slider shape tailoring and twisting allow to control energy dissipation and its scaling with contact size, thus advancing the quest toward achieving large-scale superlubricity.
