Researchers at Rice University in Houston, USA, have calculated through computational studies that a new carbon-structured substance has properties that are harder than any known material. This carbon material is called Carbyne, and its carbon atom chain is quite special, and it is connected by a triple bond atom and a single bond atom or a double bond atom. Formally due to its special structure, it is slightly harder than graphene and diamonds.

Carbyne itself is a hidden, elusive substance. Astronauts once detected this substance in space, but on Earth, scientists can only rely on artificial synthesis to extend the atomic chain to 44 atoms. Until now, this substance has been considered too active to be used to study and is not reliable enough.

But the researchers also said that although the Carbyne property is very active, under certain structures, the substance can be stable for several days in the laboratory.
