Nanotubes find niche in electric switches
Study finds nanotube structures could improve electric motors
HOUSTON -- (March 9, 2009) -- New research from Rice
University and the University of Oulu in Oulu, Finland, finds that
carbon nanotubes could significantly improve the performance of
electrical commutators that are common in electric motors and
generators.
The research, which appeared online this month in the journal
Advanced Materials, finds that "brush contact" pads made of
carbon nanotubes had 10 times less resistance than did the
carbon-copper composite brushes commonly used today. Brush
