Nanotubes best heat conductors

from the who-needs-metals? dept.
Senior Associate Brian Wang writes "University of Penn scientists have found that carbon nanotubes are the best heat conductors. Sound can conduct thermal energy at 10,000m per sec down the tubes. They could be very useful as heat sinks in chips. The weak binding between tubes that allows the heat conductance must be overcome in order for strong materials to be created from thicker structures: http://www.eurekalert.org/rele ases/up-iac083000.html"
