Nanotech advance makes carbon nanotubes more useful

User rating: 2.5 / 5 after 2 vote(s)

Strong alignment of nanotube growth with the direction of electric field lines
Researchers at UCSD have made carbon nanotubes bent in sharp predetermined angles, a technical advance that could lead to use of the long, thin cylinders of carbon as tiny springs, tips for atomic force microscopes, smaller electrical connectors in integrated circuits, and in many other nanotechnology applications. In a paper published in the April 7, 2005, issue of the Journal of Physical Chemistry B, Sungho Jin, a professor of materials science at UCSD’s Jacobs School of Engineering, reported a technique to create bent nanotubes by manipulating the electric field during their growth and adjusting other conditions.
