Abstract

Ultrapure: The absolute purity of defect-free and structurally perfect single-walled carbon nanotubes in a bulk sample can be determined with density gradient ultracentrifugation (see picture). The experimental protocol offers a quick and reliable tool and is applicable to a broad variety of nanotube materials to evaluation production and purification procedures.
