Carbon nanotubes have many potential commercial applications. They possess extraordinary strength and unique electrical properties, and are efficient conductors of heat. Nanotubes are already used in many common products, such as bicycle frames, automobile bodies, and tennis rackets.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31306164"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14061104"> <skos:prefLabel xml:lang="es">carbon nanotubes (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9829505"> <skos:prefLabel xml:lang="ca">nanotub de carboni</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:26:24</dct:created>  </skos:Concept></rdf:RDF>
