Carbon

• Fullerene (C) is an allotrope of carbon in the form of a hollow sphere, ellipsoid, tobe and many other shapes and sizes.
• Spherical fullerenes, also referred to as Bucky balls, resemble the balls used in association football.
• Cylindrical fullerenes are also called carbon nanotubes.
• Fullerenes are stable, but not totally unreactive.
• Fullerenes cannot be found in nature.
• Fullerenes are the synthetic allotropes of carbon, with lower melting and boiling points than diamond and graphite.
• Graphene is an allotrope of carbon.
• Graphene cannot be found in nature.
• Graphene is a single layer (monolayer) of graphite.
• Graphene is tightly bound in a hexagonal ring structure.
• The crystalline structure of Graphene is two-dimensional.
• In proportion to its thickness, Graphene is about 100 times stronger than the strongest steel.
• Graphene is a transparent and flexible conductor, widely used for various material device applications, including solar cells, light-emitting diodes (LED), touch panels and smart windows or phones.
