We also show that higher magnetic moments leads to slower SWCNT nucleation. This is a consequence of the extent of Fe → C charge transfer, which is proportional to the total magnetic moment. As the magnetic moment is increased, the Fe₃₈ nanoparticle has higher catalytic activity and is able to stabilise carbon in its subsurface region, thereby impeding the nucleation process.]]> Wed 24 Jul 2019 13:44:26 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36653 2 from the CVD feedstock, the formation and polymerization of B-N chain structures, and the repeated cleavage of homoelemental B-B/N-N bonds by the catalyst surface. Defect-free BNNT cap structures then form perpendicular to the catalyst surface via direct fusion of adjacent BN networks. This BNNT network fusion mechanism is a marked deviation from the established mechanism for carbon nanotube nucleation during CVD and potentially explains why CVD-synthesized BNNTs are frequently observed having sharper tips and wider diameters compared to CVD-synthesized carbon nanotubes.]]> Wed 02 Sep 2020 13:49:19 AEST ]]>
