Explanation:

Graphene is an allotrope (form) of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It is nearly transparent.
It is the basic structural element of many other allotropes of carbon, such as graphite, charcoal, carbon nanotubes and fullerenes.
Its thin composition and high conductivity means it is used in applications ranging from miniaturised electronics to biomedical devices.
These properties also enable thinner wire connections; providing extensive benefits for computers, solar panels, batteries, sensors and other devices.
The one-atom-thick sheets of carbon conduct electrons better than silicon and have been made into fast, low-power transistors. Now, for the first time, researchers have measured the intrinsic strength of graphene, and they've confirmed it to be the strongest material ever tested.
Learning: Given its strength, electrical conductivity and elasticity, it has been seen as an alternative to lithium-ion batteries since its discovery in 2004.
It can be used to develop smaller, slimmer batteries but with higher capacity.
The potential applications of graphene include water filtration and purification, renewable energy, sensors, personalised healthcare and medicine, to name a few.
