(Phys.org) —What happens when you shoot multiwalled carbon nanotubes (MWCNTs) out of a gun onto an aluminum target at a velocity of more than 15,000 mph? Scientists finally have the answer. If a nanotube reaches the target ...
One of graphene's most sought-after properties is its high conductivity. Argentinian and Brazilian physicists have now successfully calculated the conditions of the transport, or conductance mechanisms, in graphene nanoribbons. ...
