EDX and XPS measurements confirmed the successful cross-linking of GO with DSAC. The adsorption experiments were well described by the Harkin-Jura model and they followed pseudo-second order kinetics. The maximum adsorption capacity reached 666.67 mg/g at 318 K. Thermodynamic evaluation indicated a spontaneous, feasible, and endothermic in nature. Regenerability and reusability investigations demonstrated that the GO@DSAC composite could be reused for up to 10 desorption-adsorption cycles with a removal efficiency of 81.78%. The selective adsorptive performance of GO@DSAC was examined in a binary system containing Rhodamine B (RhB) and methylene orange (MO). The results showed a separation efficiency (α) of 98.89% for MB/MO and 93.66% for MB/RhB mixtures, underscoring outstanding separation capabilities of the GO@DSAC composite. Overall, the GO@DSAC composite displayed promising potential for the effective removal of cationic dyes from wastewater.]]> Thu 26 Oct 2023 15:39:53 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48410 Thu 16 Mar 2023 14:03:44 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54646 $ rac{2}{pi sqrt{3}} approx 0.37$ for the unique localization of any arbitrary region, where localization of a single point can be achieved by using two or three fixed-range beacons. We then propose a novel beacon placement structure according to the kagome lattice that achieves this maximum efficiency. Compared to recent existing methods, our proposed kagome beacon placement significantly reduces the required number of beacons by more than 15% when applied to randomly generated regions. Importantly, it does so while incurring a substantially lower computational complexity. The results of this work are promising for pico- and femto-cell deployments with applications in localization of advanced industrial automation, health monitoring in complex infrastructure, and adaptive urban development in smart cities.]]> Thu 07 Mar 2024 15:27:42 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50589 Sun 30 Jul 2023 15:16:38 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55796 Sat 22 Jun 2024 12:47:32 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55778 Sat 22 Jun 2024 12:40:09 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53887 Mon 29 Jan 2024 18:34:14 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49164 Mon 29 Jan 2024 18:34:10 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50887 Mon 29 Jan 2024 18:27:36 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50821 Mon 29 Jan 2024 18:27:31 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53251 Mon 29 Jan 2024 18:27:06 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52064 Mon 29 Jan 2024 18:26:36 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53866 Mon 29 Jan 2024 18:24:39 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50455 Mon 29 Jan 2024 18:21:54 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51312 Mon 29 Jan 2024 18:21:45 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52062 The urgent need for drastic reduction in emissions due to global warming demands a radical energy transition in transportation. The role of biofuels is fundamental to bridging the current situation towards a clean and sustainable future. In passenger cars, the use of ethanol fuel reduces gas emissions (CO2 and other harmful gases), but can bring tribological challenges to the engine. This review addresses the current state-of-the-art on the effects of ethanol fuel on friction, lubrication, and wear in car engines, and identifies knowledge gaps and trends in lubricants for ethanol-fuelled engines. This review shows that ethanol affects friction and wear in many ways, for example, by reducing lubricant viscosity, which on the one hand can reduce shear losses under full film lubrication, but on the other can increase asperity contact under mixed lubrication. Therefore, ethanol can either reduce or increase engine friction depending on the driving conditions, engine temperature, amount of diluted ethanol in the lubricant, lubricant type, etc. Ethanol increases corrosion and affects tribocorrosion, with significant effects on engine wear. Moreover, ethanol strongly interacts with the lubricant’s additives, affecting friction and wear under boundary lubrication conditions. Regarding the anti-wear additive ZDDP, ethanol leads to thinner tribofilms with modified chemical structure, in particular shorter phosphates and increased amount of iron sulphides and oxides, thereby reducing their anti-wear protection. Tribofilms formed from Mo-DTC friction modifier are affected as well, compromising the formation of low-friction MoS2 tribofilms; however, ethanol is beneficial for the tribological behaviour of organic friction modifiers. Although the oil industry has implemented small changes in oil formulation to ensure the proper operation of ethanol-fuelled engines, there is a lack of research aiming to optimize lubricant formulation to maximize ethanol-fuelled engine performance. The findings of this review should shed light towards improved oil formulation as well as on the selection of materials and surface engineering techniques to mitigate the most pressing problems.]]> Mon 29 Jan 2024 18:20:49 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51260 Mon 28 Aug 2023 13:49:14 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53909 Mon 22 Jan 2024 15:17:58 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55694 Mon 17 Jun 2024 10:32:14 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52355 Mon 09 Oct 2023 15:04:35 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52284 Mon 09 Oct 2023 10:03:25 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48223 75 years were significantly less likely to use social media compared with those aged <55 years (adjusted odds ratio 0.17, 95% CI 0.07-0.44). Health risk factors were not found to be associated with searching for health- or medical-related information. Conclusions: The internet appears to be a viable platform to engage with stroke survivors who may not be high-morbidity to conduct research and provide information and health interventions. This is important given that they are at high risk of recurrent stroke regardless of their level of disability. Exploring the technology use behaviors and the possibility of eHealth among survivors who experience higher levels of morbidity or disability because of their stroke is an area of research that warrants further study.]]> Mon 08 May 2023 10:35:04 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54102 Mon 05 Feb 2024 09:34:40 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54091 Mon 05 Feb 2024 09:21:32 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55480 Mon 03 Jun 2024 16:13:46 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55476 Mon 03 Jun 2024 16:12:24 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55467 Mon 03 Jun 2024 16:05:02 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53875 Fri 19 Jan 2024 12:40:22 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51082 Fri 18 Aug 2023 09:38:11 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53207 Fri 17 Nov 2023 11:48:02 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53133 Fri 17 Nov 2023 11:23:28 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55355 Fri 17 May 2024 15:58:03 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51707 Fri 15 Sep 2023 14:09:33 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50926 Fri 11 Aug 2023 16:01:02 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55281 Fri 10 May 2024 16:13:47 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51494 Fri 08 Sep 2023 11:58:10 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54014 Fri 08 Mar 2024 14:19:22 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54681 Fri 08 Mar 2024 11:45:22 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54663 Fri 08 Mar 2024 10:57:44 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54657 Fri 08 Mar 2024 10:49:18 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52942 Fri 03 Nov 2023 10:50:24 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:55257 Fri 03 May 2024 15:23:38 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54566 Fri 01 Mar 2024 15:52:15 AEDT ]]>
