Tensile strength compression and resilience rates of flexible graphite sheets were measured.
密度柔性石墨板的拉伸强度、压缩率和回弹率等力学性能。
But that wasn't known until 2004, when Geim and Novoselov, both of of the University of Manchester, UK, first used sticky tape to pull tiny sheets of carbon off a piece of graphite.
但是这项发现直到2004年，英国曼彻斯特大学的杰姆和诺沃塞洛夫首次用胶带从一片石墨里拉出了极小碳原子片才得以证实。
By contrast, graphite is soft and slippery because its carbon atoms form "flat" bonds, resulting in sandwiched sheets of atoms that weakly attract one another.
相反，石墨的柔软和易滑脱特性源于它的碳原子形成了“平面的”化学键，导致了三明治式的层片状原子，而层间吸引力很微弱。
Carbon nanotubes are rolled-up sheets of graphite thousands of times thinner than a human hair.
碳纳米管是由比人的头发细千倍的石墨板卷曲成的管状结构。
To make the material, the team milled raw graphite by purifying it with chemicals to reshape it into 'nano-structured configurations' which are then processed into sheets of paper.
制造这种物质，该小组把原料石墨磨碎，用化学品净化，把它重塑成“纳米结构”，然后再把它加工成纸张。
