Green synthesized of zinc oxide nanoparticles and calcined biowaste for sustainable electrodes to asymmetric supercapacitors.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Green synthesis is increasingly popular due to the focus on sustainability and biowaste recycling. This study explores zinc oxide nanoparticles (ZnO NPs) synthesized using broccoli extract, with carbon powder derived from calcined broccoli pulp as an alternative to commercial carbon in electrochemical slurries. Powders were characterized, and slurries were prepared in a three-electrode system with 6 molar (M) potassium hydroxide (KOH) electrolyte. Results showed that biowaste carbon in 50–70 nm ZnO NPs slurry increased specific capacitance by 74.64 Farad/gram (F/g). The ZnO NPs/biowaste carbon powder retained 64% stability after 500 cycles, with 400 degrees Celsius (°C) identified as the optimal calcination temperature for asymmetric supercapacitors. Thanks to this study, the energy applications of materials produced by recycling biowaste in a sustainable and non-toxic way have been examined in detail for the first time.
