Simulations predict flat liquid
Helsinki, Finland (SPX) May 25, 2015
Computer simulations have predicted a new phase of matter: atomically thin two-dimensional liquid. This prediction pushes the boundaries of possible phases of materials further than ever before. Two-dimensional materials themselves were considered impossible until the discovery of graphene around ten years ago. However, they have been observed only in the solid phase, because the thermal atomic motion required for molten materials easily breaks the thin and fragile membrane. Therefore, the possibl ... read more
