“…Chiral separation techniques such as selective chemistry, gel chromatography, dielectrophoresis, selective oxidation, ultracentrifugation and DNA wrapping chromatography have proven successful yet laborious. 28 On the other hand, metallic tubes can be laser-removed from the mix of chiralities in logic gates, leaving only switchable semiconducting tubes; 27,29,30 semiconducting tubes can be laserremoved, leaving only metallic tubes for metal matrix composites and contacts; 27 the eld emission in CNT mats and powders can be enhanced with laser radiation for screens, improving uniformity and turn-on voltage; 31,32 the tensile strength of CNT threads can be boosted by triggering tube-interlinking, chemically or with electron radiation, which improves load transfer; 33,34 nally, fully analogous to CNTs due their sp 2 carbon, the electrical conductivity in graphene inks can be improved by laser radiation. 35 2 Materials and methods…”
