However, the internal resistances of unmodified group and B-rGO group were larger at 375.21 Ω and 299.11 Ω. Besides, lower power density and output voltage were shown at 8.97 W·m ^-3 and 480 mV for control group and 13.16 W·m^-3 and 635 mV for B-rGO group. Above all, it demonstrates that G-rGO film anodes performed better and can be applied as anode materials in MFC to accelerate electricity generation.]]> Wed 09 May 2018 14:23:07 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48527 Tue 21 Mar 2023 13:31:48 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26409 Tue 16 Oct 2018 12:10:24 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42866 Tue 06 Sep 2022 09:17:31 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30099 2, O₂ and air) was employed. Results indicated 100% of phenanthrene was removed, total COD removed increased to 81.5%, 77.2% and 68.7% using N₂, O₂ and air–Fe NPs, respectively. In addition, Fe NPs were confirmed by scanning electron microscopy (SEM) and X-ray energy-dispersive spectroscopy (EDS). Finally, the degraded metabolites were identified by GC–MS to understand the degradation pathway]]> Sat 24 Mar 2018 07:37:59 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26611 Bacillus fusiformis and Fenton oxidation of their degraded metabolites using nanoscale zero-valent iron (nZVI). A 99.0% naphthalene was biodegraded by B. fusiformis in 96 h, while only 59.4% chemical oxygen demand (COD) was removed, indicating that the degraded metabolites existed in solution. To further degrade the metabolites, nanoscale zero-valent iron (nZVI) was used as heterogeneous catalyst for Fenton-like oxidation of the metabolites after biodegradation lasting 40 h. Results showed that the total the removal COD increased from 36.4% to 91.6% at pH 3.0, 1.0 g L⁻¹ nZVI, 10.0 mM L⁻¹ H₂O₂ and temperature of 35 °C. Scanning electron microscopy (SEM) showed the aggregation and corrosion of nZVI. X-ray diffraction (XRD) confirmed the existence of Fe⁰ and the presence of iron oxide (Fe(II)) and iron oxohydroxide (Fe(III)). A possible degradation pathway was proposed since two naphthalene metabolites (1-Naphthalenol and 1,4-Naphthalenedione) were detected by GC–MS.]]> Sat 24 Mar 2018 07:33:58 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24958 Sat 24 Mar 2018 07:14:18 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:25178 eucalyptus leaf extracts was used to remove mixed Cr(VI) and Cu(II), where the efficiency was 58.9% and 33.0%, respectively. In contrast, only 20.2% of Cr(VI) and 11.8% of Cu(II) were removed by adsorption using eucalyptus leaf extracts. In addition, the removal mechanism for mixed Cr(VI) and Cu(II) based on both adsorption and reduction by Fe NPs was confirmed by various characterization techniques, including the formations of Fe NPs, iron oxides and capping layer. Furthermore, the kinetics suggested that firstly, their sorption followed the pseudo second-order model well; and secondly, reduction of Cr(VI) and Cu(II) followed the pseudo-first-order model well. Finally, Fe NPs not only removed Cr(VI) and Cu(II), but also Pb(II) and Zn(II) in electroplating wastewater. This provides a new insights into the removal of metal ions using green Fe NPs with a low cost and environmentally friendly remediation strategy.]]> Sat 24 Mar 2018 07:13:53 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24054 Sat 24 Mar 2018 07:09:41 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34261 Eucalyptus leaf extract (EL-RGO) was investigated, which was characterized with ultraviolet-visible spectroscopy (UV), Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and Thermal gravimetric analysis (TG). Eucalyptus leaf extract also play both reducing and capping stabilizing agents prepared EL-RGO as shown a good stability and electrochemical properties. This approach could provide an alternative method to prepare EL-RGO in large-scale production. Moreover, the good electrochemical property and biocompatibility can be used in various applications. In addition, the merit of this study is that both the oxidized products and the reducing agents are environmental friendly by green reduction.]]> Mon 25 Feb 2019 11:39:33 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47494 Mon 23 Jan 2023 11:47:24 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:41285 Mon 01 Aug 2022 11:34:31 AEST ]]>
