The first is the layering of graphene over a fine metal grid
, perhaps aluminum, onto any flexible substrate, even plastic. Much cheaper and more robust "touch screens" should result. No iridium required!
The second is "armchair" graphene nanotubes
: "Armchair carbon nanotubes that behave like metals could revolutionize electric power systems, large and small, the researchers said. Wires made from them are predicted to conduct electricity 10 times better than copper, with far less loss, at a sixth the weight."
Both for power transmission and for (e.g.) windings in electric motors, this sounds revolutionary.
