Physicists produce stable water-based graphene dispersions

UmeƄ researchers show how activated graphene, activated carbons and other hydrophobic carbons can be dispersed in water in a form of micrometer-sized particles. The key agent that helps to make these dispersions last for ...

Graphene-based actuator swarm enables programmable deformation

Actuators that can convert various environmental stimuli to mechanical work have revealed great potential for developing smart devices such as soft robots, micro-electromechanical systems (MEMS), and automatic lab-on-a-chip ...
