Otherwise, the CoS₂@N-GN hybrid also presents superior long-term catalytic durability. Moreover, an alkaline water splitting device assembled by CoS₂@N-GN as both anode and cathode can achieve a low cell voltage of 1.53 V at 60◦C with a high faraday efficiency of 100% for overall water splitting. The tremendously enhanced electrochemical behaviors arise from favorable factors including small sized, homogenously dispersed novel CoS₂ nanocrystals and coupling interaction with the underlying conductive nitrogen-doped graphene, which would provide insight into the rational design of transition metal chalcogenides for highly efficient and durable hydrogen and oxygen-involved electrocatalysis.]]> Tue 23 Jul 2019 15:27:22 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52760 Tue 14 Nov 2023 15:32:48 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43172 Tue 13 Sep 2022 16:03:37 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43354 Thu 15 Sep 2022 15:32:33 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32571 Thu 12 Nov 2020 15:36:15 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32958 s=150, 160 and 170°) to represent the surface hydrophobicity. CFD model predicted interaction outcomes and droplet spread ratios were in reasonable agreement with the experiment at different impact Weber numbers. Increase in particle surface heat flux and corresponding rise in droplet temperature at different impact Weber numbers were also quantified which showed an increasing trend up to a critical Weber number for droplet disintegration.]]> Mon 23 Sep 2019 13:21:24 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46585 0.47Fe_0.53 nanofiber mats that were composed of individual, orientated Ni_0.47Fe_0.53 nanofibers. The key steps were processing a polyvinylpyrrolidone nanofiber template containing ferric nitrate and nickel acetate metal precursors in Ar at 300°C and then 95% Ar: 5% H2 at 600°C. The Ni_0.47Fe_0.53 fibers were nanostructured and contained Ni_0.47Fe_0.53 nanocrystals with average diameters of ~14 nm. The Ni_0.47Fe_0.53 ferromagnetic mats had a high saturation magnetic moment per formula unit that was comparable to those reported in other studies of nanostructured Ni_1-xFe_x. There is a small spin-disordered fraction that is typically seen in nanoscale ferromagnets and is likely to be caused by the surface of the nanofibers. There was an additional magnetic contribution that could possibly stem from a small Fe_1-zNi_zO phase fraction surrounding the fibers. The coercivity was found to be enhanced when compared with the bulk material.]]> Fri 25 Nov 2022 14:22:14 AEDT ]]>
