  rdf:value "Nanoestructuras con una morfología tubular cerrada, que pueden ser de pared simple o multi-pared. Las estructuras se cree que son libres de defectos, lo que lleva a una alta resistencia a pesar de su baja densidad y puede ser conductor de la electricidad o semiconductor, dependiendo de su helicidad."@es, "Nanostructures having a closed, tubular morphology that can be single-walled or multi-walled. The structures are believed to be defect free, leading to high strength despite their low density; and can be either electrically conductive or semiconductive, depending on their helicity."@en ;
