title: Fast benchtop visualization of graphene grain boundaries using adhesive properties of defects.
abstract: Highly adhesive properties of graphene grain boundaries to permanganate lead to a very quick, easy and convenient method to visualize the grain boundaries simply using an optical microscope, which would be vital to improve specific properties of graphene.
