Graphene and Carbon Nanostructures

Graphene which is a fascinating material in today’s world is an allotrope of carbon and is formed by a monolayer of carbon atoms, strongly bound in a hexagonal honeycomb matrix. Graphite is formed by stacking of grapheme layers. Graphene is the thinnest (one atom thick), strongest material and is the best conductor of heat and electricity. Graphene has its application in compsites, energy, electronics, sensors, imaging, telecommunications and biomedical technologies. Graphene has been used to improve the charge rate, capacity and longevity as garphene tin oxide in lithium ion batteries. Graphene gas/vapour sensor has been used to sense gases and have engrossed attention because of their distinct sensing performance. Carbon nanostructures such as grapheme, fullerenes, and carbon nanotubes have unique properties. Depending upon the atomic structure carbon nanotubes can be classified into semiconducting or metallic. Carbon nanotubes are going to be the next-generation material in transistors and Carbon nanomaterials will change the whole world one day.
