MIT researchers develop a way to funnel solar energy

ScienceBlog.com

CAMBRIDGE, Mass. – Using carbon nanotubes (hollow tubes of carbon atoms), MIT chemical engineers have found a way to concentrate solar energy 100 times more than a regular photovoltaic cell. Such nanotubes could form antennas that capture and focus …

Chemists make more uniform ‘Buckytubes’

ScienceBlog.com

Duke University chemists say they’ve come up with a way to grow carbon nanotubes — a.k.a. Buckytubes — that vary in size far less than those produced previously. The technique could help with the development of nanostructures with electronic properties reliable enough to use in molecular-sized circuits.
