这篇文章有点误导。 石墨烯的超导性不是在常温， 而是接近绝对零度

“此后的107年，科学界无数科学家前赴后继，一直希望研制出能够在常温条件下实现“超导体”性能的材料，却都以失败告终，直到中国科学家曹原的出现。”

But the MIT team had taken a giant leap by turning graphene into a superconductor: a material that allows electricity to flow without resistance. They achieved that feat by placing one sheet of graphene over another, rotating the other sheet to a special orientation, or ‘magic angle’, and cooling the ensemble to a fraction of a degree above absolute zero. That twist radically changed the bilayer’s properties — turning it first into an insulator and then, with the application of a stronger electric field, into a superconductor.

尽管如此， 还是了不起的成就！
