Graphene stirrer with designed movements: Targeting on environmental remediation and supercapacitor applications

Beyond the traditional focus on improvements in mechanical, electronic and absorption properties, controllability, actuation, and dynamic response of monoliths have received increasing attentions for practical applications. However, most of them could only realize simple response to constant conditi...
