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 ]]> Energy and charge transfer at the Boron Nitride Nanotube - catalyst growth interface https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47177 Tue 21 Mar 2023 18:09:43 AEDT ]]> Boron nitride nucleation mechanism during chemical vapor deposition https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36705 2O2 and NH3 precursors lead to the nucleation and growth of BN nanostructures in the presence of a boron nanoparticle. The formation of BN rings is mediated by the boron nanoparticle and is promoted by the formation of H2O. Gas-phase H2 is also produced during this process; however, we demonstrate that H2 and H2O formation serves two distinctly different roles during BN nucleation. H2 formation promotes the clustering of BxOx species to form catalytic B nanoparticles; H2O formation promotes BN bond formation and ultimately BN ring condensation, both in the gas phase and at the nanoparticle surface. Thermal annealing of amorphous BN networks formed via this reaction undergo defect healing over significant simulation times (∼20 ns) to afford tube-like BN nanostructures.]]> Thu 25 Jun 2020 15:00:41 AEST ]]> Molecular resolution in situ imaging of spontaneous graphene exfoliation https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:29904 Sat 24 Mar 2018 07:40:58 AEDT ]]> Nanostructure of deep eutectic solvents at graphite electrode interfaces as a function of potential https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27923 Sat 24 Mar 2018 07:36:08 AEDT ]]> Boron nitride nanotube nucleation during Ni-catalyzed boron oxide chemical vapor deposition https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36649 2O production being assumed to accompany the formation of BN during BOCVD, we do not observe Ni-catalyzed evolution of H2O, although significant amounts of H2 is evident. At low oxygen chemical potentials, defect-free BN ring networks are produced following the oligomerization of BN chain structures and the Ni-catalyzed cleavage of homoelemental B-B and N-N bonds. The BNNT tip structures align perpendicular to the surface via the direct fusion of adjacent BN ring networks via a mechanism that is a stark departure from that observed for carbon nanotube nucleation.]]> Mon 22 Jun 2020 14:38:29 AEST ]]> Why Carbon Nanotubes Grow https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51718 Fri 15 Sep 2023 17:54:41 AEST ]]>
