A new understanding of the physics of conductive materials has been uncovered by scientists observing the unusual movement of electrons in graphene.
Graphene can be used to help turn contaminated water into safe drinking water - desalination. Graphene based membranes can be modified to have a lot of tiny pores or spaces, meaning harmful molecules can be blocked or filtered out.
Filtering dirty water into clean water in real time is one of the potentials that graphene holds for the future of technology.
