Researchers measure giant light-conversion effect in chiral carbon nanotubes

Silvia Cernea Clark – May. 19, 2026 “Typically, when we have a macroscopic ensemble of carbon nanotubes, half of them are right-handed and the other half are left-handed,” said Junichiro Kono, a senior researcher on the study. “So, their chiral properties cancel each other out.” That cancellation effect has prevented researchers from measuring one of the material’s most … Read more
