High-quality boron nitride nanoribbons : unzipping during nanotube synthesis

Zipper examined: High-quality boron nitride nanoribbons (BNNRs) can be produced directly during nanotube synthesis without post-treatment. These BNNRs are typically several micrometers long and tens of nanometers wide. Near-edge X-ray absorption fine structure investigations indicated that the BNNRs are of high chemical purity and crystallinity.
