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:47634 2 = 0.98). Finally, the cycling experiments for MB adsorption by bagasse synthesized rGO confirmed that the as-prepared rGO was reusable. Taken together, all results in this work provided the new insights into the green reduction of GO by bagasse, and the formation of rGO/bagasse material presented a great potential in the disposal of dye waste water.]]> Tue 24 Jan 2023 14:24:10 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24636 80%). Acinetobacter venetianus immobilized on MBC demonstrated superior efficiency in degrading diesel oil (94%) compared to planktonic cells culture (82%) over a 3-day period. Moreover, the simultaneous adsorption and biodegradation of diesel oil using these immobilized cells fitted well to the pseudo second order (R² > 0.99). Scanning electron microscopy (SEM) revealed that through absorption, cells attached well to the cavum of MBC stalk cells. Fourier transform infrared analysis (FTIR) revealed that a large number of bands at 1300-1500 cm^-1 existed, demonstrating that the diesel oil was degraded and new bands were formed. Gas Chromatography Mass Spectrum (GC-MS) analysis indicated the immobilized cells could degrade diesel oil into esters and aldehydes. Results justified the applicability of MBC as the carrier matrix for immobilizing microorganisms in removing diesel oil compounds from industrial wastewater.]]> Tue 14 Nov 2023 13:37:32 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42943 Thu 08 Sep 2022 09:14:20 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:32675 Acinetobacter venetianus in 96 h, while the removal efficiency of chemical oxygen demand (COD) in the aqueous phase was only 56.8%, indicating that degraded metabolites existed in solution. To solve this problem, a Fenton-like system consisting of nanoscale zero-valent iron (nZVI) and hydrogen peroxide was used for further oxidation of the metabolites after biodegradation. Results showed that the total COD removal increased from 56.8% to 89% under the optimal condition. In addition, effects of initial pH (2.0–9.0), ZVI dosage (0–2.0 g L-1), hydrogen peroxide (H₂O₂) dosage concentration (0–15 mmol L-1) and temperature (298–308 K) on the treatment efficiency of the combined process were studied. Scanning electron microscopy (SEM) demonstrated that changes to the surface of nZVI occurred. GC-MS revealed that the degraded metabolites were mineralized practically by nZVI/H₂O₂ system. The results points towards the potential of Fenton-like oxidation as a short post-treatment after a biological process for the treatment of organic pollutants in wastewater.]]> Fri 17 Nov 2023 11:42:05 AEDT ]]>
