Researchers Make Breakthrough in the Production of Double-Walled Carbon Nanotubes

Northwestern University team develops new method to reliably produce and sort out double-walled carbon nanotubes; discovery could lower the cost of this dynamic material

View an interview with Mark C. Hersam of Northwestern University. Double-sided carbon nanotubes are highly prized for their use in solar cells and other applications, but until now creating a supply of just double-sided carbon nanotubes, instead of a mix of single- or multi-sided ones, was a challenge. Hersam and a colleague at Northwestern University announced a breakthrough technique that allows the double-sided tubes to be efficiently separated from the other types.
