Using microwave technology, a waste material such as orange peels can be converted into a green source of carbon-based materials like activated carbon, carbon quantum dots and graphene. Graphene in particular, in its various forms, is a major player in the technological revolution of recent years concerning materials. These allotropes of carbon possess properties that make them incredibly useful in engineering, chemical, and biomedical fields. Knowing that diamond and graphite are both allotropes of carbon, one day it would be nice to get a diamond from orange peels… what about that?
