Abstract

original image

Free-standing sheets made of aligned nitrogen-doped carbon nanotubes (CNx) are reported on page 1069 by Xavier Lepró and co-workers. Similar to undoped carbon nanotubes (CNTs), such sheets can be twisted into strong, weavable, sewable, and knottable CNx yarns without requiring the addition of CNT sheets to confine unaligned CNx material. These yarns exhibit catalytic activity and larger capacitances than typical twist-spun CNT yarns.
