Increased demand for plastics leads to a large amount of plastic manufacturing, which is accompanied by inappropriate disposal of plastics. The by-products of these waste plastics are microplastics (MPs; less than 5 nm in size), which are produced because of various environmental and physicochemical factors, posing hazardous effects to the ecosystem, such as the death of marine organisms due to the swallowing of plastic specks of no nutritional value. Therefore, the collection, preparation, identification, and recycling of these microsized plastics have become imperative.

- Graphene-based fiber-shaped supercapacitors (FSSCs) are gaining attention as flexible and stable energy storage devices, enhanced by techniques like heteroatom doping and metal oxide incorporation.
- The study introduces a scalable method that combines these techniques, using nitrogen and sulfur-doped graphene fibers for effective energy conversion during rapid heating processes.
- Results show a significant increase in energy storage capacity (from 8.32 F g to 68.88 F g), impressive durability (96.67% capacitance retention after 20,000 cycles), and good mechanical flexibility in the new supercapacitors.
