“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 

This themed collection is the second in a series celebrating the International Year of the Periodic Table. ‘Low Dimensional Carbon Systems’ features papers from across the Materials and Nano journal porfolio, including Materials Horizons, Nanoscale Horizons, Journal of Materials Chemistry A, B, C, Nanoscale, and Nanoscale Advances. The papers selected for this themed issue focus on low dimensional carbon-based systems across a variety of applications.
