    The electronic structure of an electrode can affect the electron transfer rate of electrochemical processes at its surface. Now, it has been shown that varying the ‘twist’ angle between two stacked layers of graphene modifies the bilayer electronic structure and provides a new dimension to control interfacial redox activity.

    Graphene oxide sheets hold promise for a variety of applications but are disordered and inhomogeneous on synthesis. Although processes to resolve this exist they typically remove oxygen groups, affecting the sheets’ properties. Now, a scalable, mild thermal annealing procedure has been devised that enhances the optical and electronic properties of graphene oxide sheets through phase transformation, while preserving their oxygen functionality.

    The chemical modification of graphene is important for its use in many applications. Now it is shown that the reactivity of graphene towards covalent modification varies widely depending on its underlying support substrate, and that the substrate can be patterned to induce spatial control of chemical reactions in graphene.

    Efforts to make graphene more useful for applications include altering its bandgap and increasing its processability. Both of these can be solved by chemically modifying the material, and now a wet chemical method has been developed that functionalizes graphene in bulk starting from pristine graphite.
