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

MXenes are a promising class of 2D materials, with prospects in applications such as electromagnetic interference shielding, energy storage, catalysis, and thermal management. Despite the importance of understanding their thermal transport properties, it is not clear whether electrons or phonons dominate heat transport, and the experimentally obtained in-plane thermal conductivities vary substantially. Here, we address this by studying in-plane heat transport in single Ti3C2Tx MXene flakes using spatiotemporal microscopy, directly visualizing heat transport in space and time. We obtain a thermal diffusivity of 0.05 cm2 s-1, corresponding to an in-plane thermal conductivity of 13-16 W m-1 K-1. Using an upper limit for the electronic conductivity based on terahertz measurements, we find that electrons carry at most half of the heat. This shows that─despite their metallic nature─phonons play an important role in the heat transport of Ti3C2Tx MXene, providing an unconventional combination of heat and charge transport properties.
