Elucidating the origin of decoupling in glass-forming liquids through high-temperature activation free energies.

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
It is well established that many glass-forming liquids exhibit a deviation from the Stokes-Einstein relation, which is commonly quantified by a power-law relation (so-called fractional Stokes-Einstein relation) between the mass diffusion coefficient [Formula: see text] and the momentum diffusion coefficient, corresponding to the shear viscosity [Formula: see text]. This ubiquitous phenomenon is often attributed to dynamic heterogeneity upon cooling, characterized by the progressive growth of the average size and lifetime of dynamic clusters of particles having excessively high or low mobility. However, a predictive theoretical understanding of the non-universal power-law decoupling exponent [Formula: see text] has been elusive. Here, for a wide variety of simulated glass-forming systems, we determine the power-law relation between the structural relaxation time [Formula: see text] and the peak time [Formula: see text] of the non-Gaussian parameter, that is, [Formula: see text], analogous to the power-law relation between [Formula: see text] and [Formula: see text] in the widely studied Kob-Andersen glass-forming liquid. We confirm the prediction from the string model of glass formation that [Formula: see text] is determined by the ratio of the high-temperature activation free energies for [Formula: see text] and [Formula: see text] in the temperature regime where dynamic heterogeneity is minimal. This finding suggests that dynamic heterogeneity is not the cause of decoupling, but rather a symptom. Our study emphasizes the role of the high-temperature liquid dynamics in understanding the fundamental mechanisms of glass formation.
