Microstructural studies confirmed that no relevant chemical reaction occurred within the foam, in particular in the vicinity of the particle-matrix interfaces. The mechanical properties of the produced FG-MSF were evaluated using quasi-static compression testing. The results showed that the deformation mechanism of the FG-MSF is a mixed mode and varies between the two different filler layers. The energy absorption of the FG-MSF sample was increased compared to uniform syntactic foams containing only a single particle filler.]]> Tue 22 Jun 2021 18:36:18 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36938 + (0.01 M AgNO₃ in ACN) reference electrode. Situated between the opposing AC electrodes, between two separators, is a Pt sensing electrode, the potential of which is either monitored or controlled to explore either electrolyte fluxes during cycling, or the formation of soluble species in the electrolyte, respectively. It was deduced that electrolyte ions are strongly associated with the AC electrodes rather than between the electrodes even without an applied potential. Furthermore, aging of the electrochemical system with cycling (cyclic voltammetry) is also explored. Even with identical electrodes it is noted that the individual electrodes behaved differently as a result of anion versus cation association. Finally, at cell voltages approaching 2 V, oxidation of the positive electrode is observed, liberating species into the electrolyte. The implications of these observations have been discussed.]]> Tue 21 Jul 2020 11:05:42 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:37262 -1. Of the advanced materials, the metal organic framework, MIL-101 has an acceptable value of 985 L g^-1. Likewise, judgement based on a figure of merit basis (e.g., regeneration, reusability, breakthrough volume, and cost) confirms the apparent superiority of activated carbon for the removal of aromatic hydrocarbons like toluene over all sorbent materials evaluated on parallel basis.]]> Tue 15 Sep 2020 12:16:30 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36165 −1) and pore volume (0.21 cm³ g⁻¹). FTIR and XPS characterization indicated that AC2 possessed a distinctive configuration of functional groups, of which the basic oxygenic groups (60%) provided more hydrophobic adsorption sites for ROC. 3D‐EEM spectra suggested more aromatics and fluorescent materials were removed by AC2 compared with AC1. GC‐MS further confirmed that AC2 had stronger affinity with the ROC in BTCW, especially for PAHs and heterocyclic compounds. Conclusion: Surface chemistry is vital to the adsorption of ROC from coking wastewater, of which basic oxygenic functional groups have specific interactions with PAHs and heterocyclic compounds. The mechanism that best explains ROC adsorption is π–π dispersion between carbon materials and the pollutants, as well as the hydrogen‐bonding interactions. This study provides an encouraging and practical guide to ROC adsorption from BTCW in future operations.]]> Thu 20 Feb 2020 14:45:17 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:46822 + reference electrode, individual electrode potentials were measured showing that even though it is a symmetrical device, polarization on the positive electrode was always greater than the negative electrode, implying that the negative electrode capacitance is greater. Deconvolution of the i-t transients from the SPECS experiment across the device voltage window can be accomplished in a similar fashion to the study of a single electrode, in which case geometric and porous capacitances, as well as diffusion and residual processes are identified. Similarly, the components of the i-t transients can be converted into voltametric data, providing access to individual electrode performance over a wide range of sweep rates in the device. The inclusion of a sensing electrode between he positive and negative electrodes is also described, providing insight into electrolyte fluxes and electrode stability within the device.]]> Thu 01 Dec 2022 10:00:23 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:49214 Sun 07 May 2023 09:37:16 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:9797 Sat 24 Mar 2018 08:10:03 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27748 Sat 24 Mar 2018 07:27:45 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:3301 Sat 24 Mar 2018 07:22:24 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24763 Sat 24 Mar 2018 07:14:08 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48012 Mon 29 Jan 2024 18:33:38 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36983 Mon 29 Jan 2024 18:02:09 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40107 60 and C₇₀ fullerene (CFEx) and Super-P carbon black were tested and compared as cathodes for non-aqueous aluminium-ion batteries (AIBs). These materials differ in their general structure, porosity and morphology. Fullerenes display a crystalline structure, whereas hemp fibers, Super-P and hair are amorphous in nature. Of all materials, AC obtained from hair recorded the highest specific capacity after 50 cycles at 103 mAh g⁻¹ with a Coulombic efficiency of ∼90 % at a current rate of 50 mA g⁻¹. Both hemp fibers and Super-P achieved their highest specific capacities at 56 mAh g⁻¹ and 84 mAh g⁻¹ respectively. CFEx recorded its highest capacity at 78 mAh g⁻¹ and maintained it for 50 cycles.
