Electrochemically “Writing” Graphene from Graphene Oxide

open access: yesSmall, 2013
A novel approach of patterning graphene on conductive surfaces based on local electrochemical reduction of graphene oxide is reported. Graphene is "written" from typical graphene oxide dispersion by applying negative potential on conductive surfaces vs.

Graphene and graphene oxide for desalination

open access: yesNanoscale, 2016
There is a huge scope for graphene-based materials to be used as membranes for desalination. A very recent study has confirmed that 100% salt rejection can be achieved for commonly used ions by utilizing single layer nonporous graphene. However, the cost effective fabrication procedure for graphene oxide membranes with precise control of pore size can ...

Superflexibility of graphene oxide [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
SignificanceBending 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 rigidity.
