近日，由英国曼彻斯特大学领导的一个国际研究小组开发一种新纳米材料，它能反射最初在复杂人造结构——扭曲双层石墨烯中发现的“魔幻角度”效应。扭曲双层石墨烯是近年来物理学研究的一个关键领域。相关论文8月12日刊登于《自然》。
据美国国家科学院院刊（PNAS）近日消息称，美国科学家在两块不同的陨石中发现了超导材料，这是超导材料在太空中形成的第一个证据。这一发现的重要意义不仅在于它是罕见的天然形式的超导材料，还为人类寻找室温超导材料点燃了新希望。超导材料即超导体，指在某一温度下，电阻为零的导体。在实验中，若导体电阻的测量值低于10Ω，可以认为电阻为零。而超导体不仅具有零电阻的特性，还可以完全抗磁性。因此超导体在传输过程中几...
