"doped graphene... make them more suitable for optical and electronic nanodevices... single elements boron, nitrogen, oxygen, phosphorus and sulfur, a two-element combination of boron and nitrogen, and a three-element mix of boron, nitrogen and takes about one second, is both catalyst- and solvent-free, and is entirely dependent on "flashing" a powder that combines the dopant elements with carbon black"
