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

We developed composite photoresins for sustainable production of microarchitected carbon electrodes via stereolithography (SLA) 3D printing. The composite resins contain 20-25 mass% water that decreases the amount of organic waste. After printing, the scaffolds were pyrolyzed into honeycomb carbon microlattices (hCMLs) at 1,000°C in vacuum. hCMLs show reduced density as the water content increases, inferring subnanoscale structural changes within the constituent carbon. Ni added to photoresin thrusts graphitization at 1,000°C so reduces thermal energy conventional graphitization requires, especially when water delivers individual Ni ions. The homogeneously dispersed Ni ions, in contrast to Ni nanoparticles that aggregate, interconnected graphitized zones in hCMLs to lower electrical resistivity by ∼50%. The Ni-doped hCMLs readily serve as a bifunctional electrocatalyst for water splitting, inspiring design of functional microarchitected carbon composites. Our results can reduce waste and save energy in fabricating carbon microarchitectures, benefitting a wide range of electrical, electrochemical and other applications.
