Results: At the low salt concentration of 10g kg^-1 , pressurisation prior to cooking (P-C) treatment induced barramundi gels with comparable mechanical properties and water-holding capacity to those of conventional heat induced (HI) gels with 20g kg^-1 added salt. At salt concentration of 20g kg^-1, pressurisation prior to setting (P-S) and P-C gels exhibited higher mechanical properties and water-holding capacity as compared to HI gels. Scanning electron microscopy images showed a smooth and dense microstructure of P-C and P-S gels whereas the microstructure of HI gels is rough and less compact. Conclusions: P-C treatment can reduce salt concentration added to barramundi gels to 10g kg^-1. P-S and P-C treatment can result in higher mechanical and functional properties of barramundi gels at conventional salt concentration (20g kg^-1) as compared to HI gels.]]> Wed 13 Mar 2019 13:19:22 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:16997 Wed 11 Apr 2018 12:52:52 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:28933 Sat 24 Mar 2018 07:31:28 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:24936 Sat 24 Mar 2018 07:14:20 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:47582 Mon 23 Jan 2023 14:21:37 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44527 50Al₅₀ melt under high pressures. While the tracer diffusion coefficients at the equilibrium state predicted by Green-Kubo and the Einstein equations follow the Arrhenius relationship and agree well with the experimental and theoretical results, a linear relationship between the logarithm of tracer diffusion coefficients and the external pressure is addressed in term of an activation volume modified Arrhenius relations. It is understood that the autocorrelation velocity functions (VACF) characterizes the capacity of an atom memorizing the velocity, which has also been considered as one of important approaches revealing thermodynamics, kinetics and structure relaxation dynamics of melts. The onset of the negative region of VACF is in line with the plateau of the meaning square displacement representing the cage effect of the system. The initial damping oscillations of VACFs are due to the momentum relaxation caused by the collision between the tagged atoms and its neighbor ones while the subsequent rises result from the energy relaxation. This work provides an insight into the physical factors controlling these dynamic behaviors under extreme conditions of Ni-Al, which could be extended to the other advanced materials.]]> Mon 17 Oct 2022 09:38:37 AEDT ]]>
