  rdf:value "Single- or multilayer nanotubes composed of cylindrical graphene sheets of bonded carbon atoms, and closed at either end with caps containing pentagonal rings. These nanotubes are single molecules typically measuring a few nanometers in diameter and several microns in length."@en, "Los nanotubos de una sola o múltiples capas compuestas de láminas de grafeno cilíndrico de átomos de carbono y cerrado en ambos extremos con tapas que contienen anillos pentagonales. Estos nanotubos son moléculas individuales que suelen medir unos poco nanómetros de diámetro y varias micras de longitud."@es ;
