Graphene made to superconduct or to insulate

Quote:Scientists have paradoxically tuned graphene, the so-called ‘wonder material’, to exhibit electrical properties at both extreme ends. According to the findings of researchers at MIT and Harvard University, graphene can operate as an insulator (electrical charge cannot pass through the material) or as a superconductor (electrons can travel through the material without resistance).

Who knows, might be some kind of "all-purpose electronic substrate" or technological "monistic stuff" someday that accomplishes such without any doping of impurities whatsoever. Hopefully this structural graphene (or something else) could eventually be modified from having total blockage (in its opposite insulator configuration) to being variable on that so as to provide resistor function. Then research discovers other structural attributes that can provide capacitance, on/off switching, and modification of a stronger magnitude power flow by a weaker one (amplification of a signal).

That would be pretty nice for them to be able to incorporate the properties into those types of devices.  I've long had the hobby of designing relatively simple electronic circuits used in power supplies and amplifiers.
