一种新的方法已经被开发出来，用来精确切割和磨尖碳纳米管，它是一种附着在金属尖端的短碳纳米管。切割和磨削的机理被认为是焦耳加热引起的碳的局部汽化。人们还发现，这种“纳米生命”还可以用来切割其他纳米管和纳米线。切割过程也被发现有助于构建复杂的碳纳米管结构。
A new method has been developed to precisely cut and to sharpen carbon nanotubes using a ‘nanoknife’, which is a short carbon nanotube adhered to a metal tip. The mechanism for the cutting and the sharpening was proposed to be local vaporization of carbon caused by Joule heating. The ‘nanoknife’ was also found useful to cut other nanotubes and nanowires. The cutting process was also found useful to construct complex carbon nanotube structures.
