WebJul 4, 2024 · Nature's materials and machinery are universally asymmetric, and, for chemical entities, controlled asymmetry comes from chirality. Together with carbon nanotubes, … WebNov 13, 2012 · The electronic properties of carbon nanotubes strongly depend on their chirality, with 1/3 being metallic1, 2/3 being semiconducting with band gaps inversely …
WebJul 1, 2024 · Nanotubes of (6,5) and (7,5) chirality were obtained in this technique. With proper interaction between the Co and Mo oxides, aggregation of Co nanoparticles at high temperatures could be avoided. In addition, by optimizing the gaseous feed composition, growth and temperature, selectivity of (6,5) nanotubes was improved by ~ 55% [ 120 ]. Webchirality originates from hemispherical fullerene end-cap. To address this long standing dispute, our strategy was to decouple grown carbon structure properties from the impact …
