Carbon nano-onions are a newer carbon nanostructure with great potential in application, but synthesizing these materials conventionally requires high temperatures, expensive feedstock, or corrosive environments. Researchers at Nagoya Institute of Technology used a one-step microwave pyrolysis process to turn fish scales into carbon nano-onions with highly crystalline and functionalized structures.
