New 2D carbon material is tougher than graphene and resists cracking

Researchers have found that a two-dimensional carbon material is tougher than graphene and resists cracking—even the strongest crack under pressure, a problem materials scientists have long been grappling with. For instance, carbon-derived materials like graphene are among the strongest on Earth, but once established, cracks propagate rapidly through them, making them prone to sudden fracture.
