title: Conformational changes of graphene nanosheets induced by metal: melting metal can spin a graphene cocoon to encapsulate itself.
abstract: Graphene nanosheets can be driven to change their conformation by melting metal and, finally, a cocoon coating can be constructed to encapsulate the metal sphere. Interaction beween metal and oxygenated defects plays a leading role in conformational changes of graphene nanosheets.
