Integrated Plasma Exfoliation and Dye Degradation for Sustainable Upcycling of Spent Zinc-Carbon Battery into Supercapacitor Electrodes.
Article in ACS omega, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Graphite rods from spent zinc-carbon batteries were upcycled into graphite oxide (GO) via a cathodic surface-plasma exfoliation process, enabling the simultaneous degradation of methyl orange (MO) dye and structural transformation of the graphite electrode. The MO degradation process followed a first-order kinetic model, achieving a 98.4% removal after 30 min of plasma treatment. Under the high-energy plasma environment, the graphite layers underwent exfoliation, partial reduction, and defect generation, producing GO enriched with oxygen-containing functional groups. This upcycled GO was subsequently employed as the active electrode material for symmetric solid-state supercapacitors by using PVA-based gel electrolytes. The GO/MO device, obtained from plasma treatment in the MO-containing electrolyte, exhibited significantly improved electrochemical performance, delivering a specific capacitance of 310.05 F g
