Oxidation of Graphene on Metals [PDF]

open access: yesThe Journal of Physical Chemistry C, 2010
We use low-energy electron microscopy to investigate how graphene is removed from Ru(0001) and Ir(111) by reaction with oxygen. We find two mechanisms on Ru(0001). At short times, oxygen reacts with carbon monomers on the surrounding Ru surface, decreasing their concentration below the equilibrium value.

Superflexibility of graphene oxide [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
Significance Bending of a thin plate simultaneously involves contraction and stretching of matter relative to a neutral plane, and tensile rigidity dictates the ability of a thin platelet to be bent. If graphene or graphene oxide (GO) were actually behaving as thin platelets, they would display high bending ...
