Atomic fingerprint identifies emission sources of uranium

Uranium is not always the same: depending on whether this chemical element is released by the civil nuclear industry or as fallout from nuclear weapon tests, the ratio of the two anthropogenic, i.e. man-made, uranium isotopes ...

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 ...
