在磁化碱金属和碱金属富勒烯等离子体中，对单壁碳纳米管（SWNTs）施加正、负偏压。当加速离子通过等离子体鞘层照射到单壁碳纳米管上时，观察到单壁碳纳米管发生了剧烈的结构变形，如偏转和管切割。此外，这种现象被发现是伴随着单壁碳纳米管内的富勒烯封装的情况下，在碱性富勒烯等离子体中的正偏压应用，给出了各种原子和分子可以有效地插入我们的等离子体方法的可能性。
Positive and negative bias-voltages are applied to single-walled carbon nanotubes (SWNTs) in magnetized alkali–metal and alkali–fullerene plasmas. When accelerated ions are irradiated to the SWNTs through plasma sheaths, drastic structural deformations such as deflection and tube cutting of the SWNTs are observed to take place. Furthermore, this phenomenon is found to be accompanied by the fullerene encapsulation inside the SWNTs in the case of the positive-bias application in the alkali–fullerene plasma, giving the possibility that various kinds of atoms and molecules can effectively be intercalated by our plasma method.
