So far, most of the comments are lamenting that the superconducting temperature of 4 K is uselessly low. That's true, but beside the point. The point of superconducting graphene is not to use it as a general purpose superconductor where the goal is to have the highest Tc possible. The point of superconducting graphene is that graphene's electrons flow in a way that's very different from most materials. In most materials, if you apply a voltage, the electrons will speed up (F=MA, Newton's second law). This how a voltage drives electrons into your computer. However, because of its crystal structure, graphene is different. In graphene, electrons always travel at a constant speed, no slower and no faster. This feature of graphene is also why its electrons are sometimes called massless (despite not being truly massless). Their motion is analogous to photons, which always travel at a constant speed. And because these electrons travel like photons instead of electrons, it has a bunch of consequences in solid state physics and electronics. The importance of superconducting graphene is that we now have a new variety of superconducting electrons to study.
