- Abstract:
The article focuses on the development of ultracentrifugation at Northwestern University in Evanston, Illinois. It notes that the method separates double-walled carbon nanotubes (DWNTs) from mixtures of single-(SWNTs) and multiwalled nanotubes (MWNTs). Research shows that SWNTs can be eliminated from the mixtures through high-temperature oxidation, while DWNTs are ideal systems in studying interwall interactions.
