Carbyne, a form of carbon bond that it is extremely lightweight, stronger than any other known material, including diamond, and twice as tough and tear such as graphene. Have a look at the video…
Carbyne created and stabilized at room temperature, by a team from Rice University.
The material was first theorised in the 1960s, but until now no-one has successfully created it, with some scientists even predicting it would be impossible to synthesise in ‘real world’ conditions.
It’s thought it could have uses in micro-mechanics and incredibly strong, light-weight fabrics.
