Ultrathin gold nanoribbons with unique hexagonal crystal phase shows 'liquid-like' behaviour

A recent study led by City University of Hong Kong (CityU) has discovered that the ultrathin gold nanoribbons with unique hexagonal (4H type) crystal phase shows "liquid-like" behaviour under heating, but its hexagonal crystalline structure remains stable. This provides insight into the thermal stability of this new type of metallic nanomaterials and facilitates the development of practical applications in the future.
