Several years ago, scientists calculated the properties of an exotic form of carbon—called Carbyne—and found that it promised more strength and stiffness than any other known material. Now, it’s finally been made in a stable form inside an Austrian lab.
Researchers from the University of Vienna in Austria report in Nature Materials that they’ve managed to synthesize the material far more successfully than ever before. It’s proved so tricky in the past because Carbyne is a long one-dimensional chain of carbon atoms linked one to the other. Its structure makes it highly reactive, which means that as quickly as it’s manufactured, it’s destroyed.
But the Austrian researchers have found a way to make it while avoiding such destruction. They took two sheets of graphene, laid them on top of each other, then rolled the whole thing up to create a double-walled tube. Think of it as a graphene Thermos. Then, they synthesized the Carbyne inside the tube, providing a protective casing which allowed the material to remain in tact.
