Aspergillus heteromorphus based bio-filters was the most efficient to remove Cu and Cr from MSWC (20%). Trichoderma viride, Aspergillus heteromorphus, Rhizomucor pusillus and Aspergillus flavus based bio-filters were equally effective for elicitation of Zn (30%) and Ni (>30%) toxicity. Differential minimum inhibitory concentration, uptake of HMs, bio-sorption capacity of HMs by fungi resulted in unequal efficacy of fungal bio-filters.]]> Wed 07 Feb 2024 17:59:49 AEDT ]]> Fundamental studies of the coal to metallurgical coke transformation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50350 Wed 06 Mar 2024 14:29:51 AEDT ]]> The selective epoxidation of allyl alcohol to glycidol https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37789 Tue 20 Apr 2021 15:22:33 AEST ]]> Biochar aging in contaminated soil promotes Zn immobilization due to changes in biochar surface structural and chemical properties https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47417 Thu 19 Jan 2023 12:49:24 AEDT ]]> Examination of how variations in lignin properties from Kraft and organosolv extraction influence the physicochemical characteristics of hydrothermal carbon https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37748 Thu 08 Apr 2021 18:26:52 AEST ]]> Rapid qualitative and quantitative analysis of opiates in extract of poppy head via FTIR and chemometrics: towards in-field sensors https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:7713 Sat 24 Mar 2018 08:41:37 AEDT ]]> Nitridation of MoO₃/HZSM-5 and Fe-MoO₃/HZSM-5 https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:7692 Sat 24 Mar 2018 08:33:33 AEDT ]]> Synthesis and characterisation of 3-dimensional hydroxyapatite nanostructures using a thermoplastic polyurethane nanofiber sacrificial template https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26275 Sat 24 Mar 2018 07:40:16 AEDT ]]> A temperature programmed desorption study of the interaction of ethyl cyanoacetate and benzaldehyde on metal oxide surfaces https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26756 in situ FTIR experiments.

Increasing the temperature from 160 to 220 °C increased the yield of hydrothermal carbon for each saccharide for the (NH4)2SO4 solution, whereas (NH4)2HPO4 produced a yield that was independent of temperature. The addition of (NH4)2SO4 increased the yield obtained at 220 °C by 4.27, 7.03 and 2.01 wt% for glucose, fructose and sucrose over the baseline salt free solution, respectively. (NH4)2SO4 also increased the quantity of acid produced and the average size of the hydrothermal carbon spheres. Conversely, (NH4)2HPO4 produced carbon structures consisting of interlocked spherical shapes and produced almost no acidic products. XPS analysis revealed that (NH4)2SO4 incorporated nitrogen and sulfur into the hydrothermal structure, while (NH4)2HPO4 only allowed nitrogen to be incorporated. It was assessed that NH4+ enhances the production of hydrothermal carbon, except in the presence of PO43−, which prevents the reaction from effectively forming hydrothermal carbon and organic acids.]]> Mon 05 Dec 2022 09:19:32 AEDT ]]> Assessment of chromium hyper-accumulative behaviour using biochemical analytical techniques of greenhouse cultivated Sonchus asper on tannery waste dump site soils https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42616 Fri 26 Aug 2022 15:54:25 AEST ]]>
