The carbon structure in coke generally is generally in the form of non-graphitic turbostratic structure, which exhibits isotropic property. There is a lack of information in terms of the 3D carbon structure model of coke/semi-coke and how these structures evolve from hydrocarbon sheets to more stable structures above 500 °C in the coke oven. This review also concludes future research scopes and the limitations of current knowledge.]]> Tue 31 Aug 2021 09:15:32 AEST ]]> Production of carbon nanotubes on bio-char at low temperature via microwave-assisted CVD using Ni catalyst https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47619 Tue 24 Jan 2023 12:25:05 AEDT ]]> HRTEM analysis of carbon structure evolution during the formation of metallurgical coke and impacts on coke quality https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:54357 Tue 20 Feb 2024 16:26:02 AEDT ]]> Investigation into the impact of coal blending on the carbon structure of chars obtained from Chinese coals during coking https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:55303 Tue 14 May 2024 17:52:03 AEST ]]> Formation of hollow carbon nanofibers on bio-char during microwave pyrolysis of palm kernel shell https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30879 ID/IG ratio decreased from 0.95 to 0.86, indicating higher order of the carbon layers of the HCNFs. Energy dispersive X-ray spectroscopy (EDS) showed the presence of Fe, K, and Ca in HCNFs structure which may have played a catalytic role during their formation and growth. Mechanism of formation and growth of HCNFs under microwave irradiation were proposed and discussed. The HCNFs-coated bio-char has great potential for removal of heavy metals from waste water.]]> Sat 24 Mar 2018 07:26:36 AEDT ]]> Direct synthesis of hollow carbon nanofibers on bio-char during microwave pyrolysis of pine nut shell https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47503 Mon 23 Jan 2023 12:08:24 AEDT ]]> Impact of pressure on the carbon structure of char during pyrolysis of bituminous coal in pressurized entrained-flow reactor https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42309 c), interlayer spacing (d002) and lateral size of the graphite structures (La) were used to evaluate the graphitic structures in chars. The results showed an increase in Lc,, La, and the average number of graphene sheets with pyrolysis pressure, indicating a more ordered carbon structure at elevated pressures. The d-spacing of char was in the range of 3.34-3.37 Å, similar to typical graphitic structures.]]> Mon 22 Aug 2022 09:14:19 AEST ]]>
