Tiny magnetic coils could be used to clean up microplastics in the ocean

The video discusses a study on carbon nanotubes that can help reduce microplastic pollution in oceans. The research, a collaboration between several universities, was published in the Journal of Matter. The nanotubes are spiral-shaped, magnetic, and coated with nitrogen and manganese. They are mixed with peroxide monosulphate to generate reactive oxygen species, breaking down microplastics into harmless compounds. Trials showed a 30-50% reduction in microplastics within eight hours. The nanotubes can be retrieved using magnets for reuse.
