      Researchers Find Way to Make 'Buckyballs'
      Conduct Electricity at Higher Temperatures
      Associated Press

      WASHINGTON -- Researchers have found a way to make carbon
      "buckyballs" conduct electricity with extreme efficiency at warmer
      temperatures, a finding that could lead to new types of ultrafast
      computers.

      Scientists at Lucent Technologies ' Bell Labs report that they
      achieved superconductivity -- electricity flowing without resistance
      -- with carbon-60 at a temperature of about minus-249 degrees by
      combining the carbon molecules with two chemical compounds,
      chloroform and bromoform.

      This mixture substantially raises the temperature at which carbon-60
      can achieve superconductivity. Previous experiments by the Bell Labs
      group had shown that carbon-60 -- known as fullerenes or buckyballs
      after Buckminster Fuller -- when mixed with other chemicals could
      superconduct at minus-366 degrees F.

      A report on the research appears Friday in the journal Science.
