Edgecarboxylated graphite (ECG) was produced by grinding pristine graphite in a planetary ballmill machine. Transmission electron microscope was used to confirm the layers of graphene in ECG. The elemental analyses showed that the oxygen contents are different between ECG samples. The vibrational analysis of single and fivelayered graphene was conducted using finite element method within ...

May 12, 2014· Graphene, a twodimensional honeycomb lattice of carbon atoms, is carbon flatland. Top Left: If we wrap it up into a ball, we get Bucky balls. If we wrap it into a cylinder, we get a carbon nanotube. And if we stack graphene sheets, we get graphite. Top right: the band structure of graphene, which governs how its electrons behave.
