WebFigure 1.1: Number of manuscripts with “graphene” in the title posted on the preprint server. In interpreting these numbers, one must, however, consider that several publica-tions on graphene appeared before 2006, e.g. in the framework of carbon-nanotube or graphite research. At this moment, the name “graphene” was not commonly used. WebThe actual lewis structure of graphite is very much complex due to having layered structure. Graphite is made with only carbon atom in which one carbon atom is bonded with another three carbon atoms. So, one among the four valance electrons is left as nonbonding electron pair. ...
