"catalyst allows precise control over chirality... single-chirality-controlled synthesis, chiral index (6,5) at ultra-high purity >95%... highly specialized growth NiSnFe ternary catalyst enabling selective synthesis of (6,5) chirality CNTs... chirality-pure bundle (6,5) CNT structures show >20X increased photoluminescence lifetime, compared to isolated (6,5) CNTs. This technique could potentially be used in the future to achieve other chiralities as well... semiconductors,  aircraft/ spaceship and biomedical device construction"
