120,000 cycles supercapacitors: softening of hard water and fabrication of high-performance biochar via plant-coupled uptake of nanoplastics

New Method of Fabricating Carbon Materials via Uptake of Nanoplastics into Eichhornia crassipes for Enhancing Supercapacitance

Researchers used water hyacinth plants that had absorbed polystyrene nanoplastics as a raw material to produce high-performance carbon electrodes for energy storage. While the study is primarily about materials engineering, it demonstrates a novel approach to removing nanoplastics from water using plants and converting the contaminated biomass into a useful product, potentially addressing two environmental problems at once.
