Unwinding of a carbon nanoscroll due to high speed rotation

Unwinding of a carbon nanoscroll due to high speed rotation

A carbon nanoscroll (CNS) can be formed easily by rolling a graphene sheet around a carbon nanotube (CNT) [Zhang and Li, 2010, APL, 97, 081909]. When the CNS is driven by the rotary CNT to rotate at a high speed, the attractive interaction within the CNS or between the CNS and CNT is crippled by the...
