Chemically Specific Multiscale Modeling of the Shear-Induced Exfoliation of Clay-Polymer Nanocomposites.

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
We recently showed, using chemically specific modeling and simulation, how the process of intercalation of polymers within clay sheets occurs, transforming the large-scale materials properties by a specific set of spatial and temporal processes that can lead to exfoliation. Here, we use the same hierarchal multiscale modeling scheme to understand the processes that occur during the shear-induced processing of clay-polymer nanocomposites. For both hydrophobic polymers (polyethylene) and hydrophilic polymers (poly(ethylene glycol)), we used free-energy methods to identify the lowest-free-energy separation of the clay sheets; the polymer molecules spontaneously intercalate into the clay interlayer from the surrounding polymer melt. We apply shear forces to investigate exfoliation and find that while exfoliation is promoted by shearing, it is the surfactant molecules that play the dominant role in resisting it.
