What is it about?

If you knew graphene, the impurities reported in this work is really graphene before the word of graphene appeared at 2004.

Why is it important?

The method to controlled produce graphene impurities is really developed as a classical method called as unzipping nanotube since 2010.

Perspectives

Other scientists observed nanotube early, but didnt think it is a nanotube like Iijima. I observed graphene, but didnt think it is a graphene like Germ.
