Abstract
The invention relates to a method for shaping small three-dimensional articles such as nanotube exhibiting a layered structure through material removal such that the article is controllably shaped to exhibit a desired contour. Typically, material removal does not require use of a chemical etchant and is carried out while the article and a shaping electrode are positioned in contact material removal relationship with under a potential difference. The invention also relates to nanotubes and small three-dimensional articles exhibiting a layered structure having a controllably shaped contour.
Claims24
A method for shaping a nanotube, comprising the steps of:
- (a) providing a nanotube and
- (b) using a shaping electrode to remove material from a portion of the nanotube such that the nanotube is controllably shaped to exhibit a desired contour, wherein material removal is carried out while the nanotube and the shaping electrode are under a potential difference.
A method for shaping a three-dimensional solid article, comprising the steps of:
- (a) providing a three-dimensional solid article and
- (b) using a shaping electrode comprising a nanotube to remove material from a portion of the three-dimensional solid article such that the solid article is controllably shaped to exhibit a desired contour, wherein material removal is carried out while the solid article and the shaping electrode are under a potential difference.
A method for shaping a nanotube, comprising removing material from a portion of a nanotube through controlled application of energy until the nanotube exhibits a desired contour, wherein material removal is carried out without need for a chemical etchant.
