Despite the electropositivity of these alkali metal adsorbates, analysis of charge transfer between the alkali metal, the substrate and the adsorbed graphene layer indicates that charge transfer does not give rise to the observed regioselective reactivity. Instead, the increased reactivity induced in the graphene structure is shown to arise from the geometrical distortion of the graphene layer imposed by the intercalated adsorbed atom. We show that this strategy can be used with arbitrary adsorbates and substrate defects, provided such structures are stable, towards controlling the mesoscale patterning and chemical functionalisation of graphene structures.]]> Wed 24 Jul 2019 12:34:22 AEST ]]> A global reaction route mapping-based kinetic Monte Carlo algorithm https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:29595 Wed 11 Apr 2018 15:12:08 AEST ]]> Chiral-selective etching effects on carbon nanotube growth at edge carbon atoms https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:35478 Thu 30 Jan 2020 16:34:09 AEDT ]]> Stochastic structure determination for conformationally flexible heterogenous molecular clusters: application to ionic liquids https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:18213 Sat 24 Mar 2018 08:04:55 AEDT ]]> Quantum chemical investigation of epoxide and ether groups in graphene oxide and their vibrational spectra https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:20347 6h-symmetry is determined by two factors - viz. the disruption of the p-conjugation of the HGF and the geometrical deformation of the HGF structure. The thermodynamically most stable structure is achieved when the former factor is minimized, and the latter factor is simultaneously maximized. Infrared (IR) spectra computed using DFT and DFTB reveal a close correlation between the relative thermodynamic stabilities of the oxidized HGF structures and their IR spectral activities. The most stable oxidized structures exhibit significant IR activity between 600 and 1800 cm⁻¹, whereas less stable oxidized structures exhibit little to no activity in this region. In contrast, Raman spectra are found to be less informative in this respect.]]> Sat 24 Mar 2018 08:02:57 AEDT ]]> Revealing the dual role of hydrogen for growth inhibition and defect healing in polycyclic aromatic hydrocarbon formation: QM/MD simulations https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:20269 Sat 24 Mar 2018 07:59:54 AEDT ]]> Nucleation of graphene precursors on transition metal surfaces: insights from theoretical simulations https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:20268 Sat 24 Mar 2018 07:59:54 AEDT ]]> Temperature dependence of catalyst-free chirality-controlled single-walled carbon nanotube growth from organic templates https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:18378 Sat 24 Mar 2018 07:52:41 AEDT ]]> Step-edge self-assembly during graphene nucleation on a nickel surface: QM/MD simulations https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:21358 Sat 24 Mar 2018 07:51:28 AEDT ]]> Nearly exclusive growth of small diameter semiconducting single-wall carbon nanotubes from organic chemistry synthetic end-cap molecules https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:26980 Sat 24 Mar 2018 07:26:59 AEDT ]]> Carbon coating precedes SWCNT nucleation on silicon nanoparticles: insights from QM/MD simulations https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:23699 Sat 24 Mar 2018 07:13:26 AEDT ]]> Quantum chemical simulation of carbon nanotube nucleation on Al₂O₃ catalysts via CH₄ chemical vapor deposition https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:23406 Mon 12 Aug 2019 13:57:03 AEST ]]> How does acetonitrile modulate single-walled carbon nanotube diameter during CVD growth? https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:35218 Mon 03 Apr 2023 16:57:57 AEST ]]> Chiral-selective carbon nanotube etching with ammonia: a quantum chemical investigation https://ogma.newcastle.edu.au/vital/access/manager/Repository/uon:29491 Fri 28 Jun 2019 11:53:08 AEST ]]>
