Carbon nanotubes break small record
Researchers from Meijo University in Japan and Research Centre Jülich in Germany have made what they say is the smallest stable carbon nanotube. The tube, just 3 Angstroms in diameter, grew inside a multiwalled carbon nanotube during a hydrogen arc discharge process. “This breaks the theoretical limit of 4 Angstroms, and reaches their [the tubes’] minimum structural limit,” Xinluo Zhao of Meijo University told nanotechweb.org.
