“The discovery of graphene created great sensation and has given rise to research on various other 2D new structures, especially inorganic elemental materials and 2D compounds.” – C.N R. Rao
“Until a few decades ago, it was thought that there were only two stable forms of carbon, namely graphite and diamond. Nanoscale carbon allotropes (fullerene, carbon nanotubes, graphene) were discovered soon thereafter. This led to a renewed interest in carbon structures, due to the surprising electronic, optical and mechanical properties exhibited by these allotropes.” – Federico Rosei
