(a) HRTEM image of a dried lightest fraction of graphene suspension obtained from the decanted liquid substance after graphene-containing colloid sedimentation during 12 hrs (Gr0). Inset is a magnified part of the image taken from the regions enclosed by the white squares (not to scale); it shows graphene hexagons. The ovals note 1- and 2-layer graphene flakes. (b) Electron diffraction pattern.
