Research outputs 2022 to 2026

As a sustainable and green approach, carbocatalysis, a metal-free strategy, has shown exceptional results in advanced oxidation processes (AOPs). Nonetheless, the recovery of these catalysts has been a major shortcoming over the years. Herein, three-dimensional nitrogen-doped graphene macrostructures (3D-NGMs), in the form of macro cubes, were synthesised by a simple cross-linking and thermal annealing procedure, after which they were employed in the activation of peroxydisulfate (PS) for the degradation of sulfamethoxazole (SMX). The catalytic cubes were loaded with different amounts of nitrogen precursor to investigate the role of nitrogen configuration in the sp2 hybridised carbon network on AOPs. NGC3 cubes …

Corrosion Behavior And Mechanisms Of The Heat-Treated Ti5cu Produced By Laser Powder Bed Fusion, Xin Wang, Peng Qin, L. Y. Chen, Hongqi Sun, Laichang Zhang

Research outputs 2022 to 2026

This work investigated the corrosion behavior of laser powder bed fusion produced (LPBFed) Ti5Cu and its heat-treated counterparts at 740 and 900 °C (named as HT-740 and HT-900 respectively) in Hank’s solution. The results indicated that the presence of acicular a'-Ti phase in LPBFed Ti5Cu was beneficial to corrosion, but the corrosion resistance of HT-740 and HT-900 were increased owing to the dual-phase microstructure (a'/a-Ti + Ti2Cu) or the increased content of Ti2Cu phase in the microstructure. The Ti2Cu phase could provide an ‘envelope’ protection to the a'/a-Ti phase and slow down the micro-galvanic reaction between a'/a-Ti phase and Ti2Cu …

Cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) is an immune checkpoint expressed in regulatory T (Treg) cells and activated T lymphocytes. Despite its potential as a treatment strategy for melanoma, CTLA-4 inhibition has limited efficacy. Using data from The Cancer Genome Atlas (TCGA) melanoma database and another dataset, we found that decreased CTLA4 mRNA was associated with a poorer prognosis in metastatic melanoma. To investigate further, we measured blood CTLA4 mRNA in 273 whole-blood samples from an Australian cohort and found that it was lower in metastatic melanoma than in healthy controls and associated with worse patient survival. We confirmed these findings …

Research outputs 2022 to 2026

The presence of bypass diodes in photovoltaic (PV) arrays can mitigate the negative effects of partial shading conditions (PSCs), which can cause multiple peak characteristics at the output. However, conventional maximum power point tracking (MPPT) methods can develop errors and detect the local maximum power point (LMPP) instead of the global maximum power point (GMPP) under certain circumstances. To address this issue, several artificial intelligence (AI)-based methods have been proposed, but they result in complicated and unreliable methodologies. This study introduces the driving training-based optimization (DTBO) method, which aims to address the partial shading (PS) problem quickly and reliably in …

We examine Australians’ preferences for resettling people displaced by climate change from overseas (‘climate refugees’), from within Australia (‘internal climate refugees’), and people displaced by war. Across three studies (Study 1N = 467, Study 2N = 1679, Study 3N = 492), our findings reveal greater support for resettling refugee groups already residing in the nation: internal climate refugees and refugees of war. Although support for all three groups was reasonably high, participants were consistently and significantly less supportive of resettling international climate refugees. Both groups of international refugees (relocating due to war or climate changes) were viewed as posing greater …

Global Uncertainty And Economic Growth–Evidence From Pandemic Periods, Deepa Bannigidadmath, M. H. A. Ridhwan, Fiskara Indawan

Research outputs 2022 to 2026

This paper investigates whether global uncertainty predicts economic growth rates using a global sample of 136 countries. We use the panel regression model and find strong evidence that global uncertainty negatively predicts the economic growth rate. Further, the negative impact of global uncertainty on economic growth rates is amplified during pandemic periods versus non-pandemic periods. Our main findings hold after a range of robustness tests.

The Impact Of Acute Calcium Intake On Bone Turnover Markers During A Training Day In Elite Male Rowers, Bronwen Lundy, Alannah K. A. Mckay, Nikita C. Fensham, Fensham, Nicolin Tee, Bryce Anderson, Aimee Morabito, Megan L. R. Ross, Marc Sim, Kathryn Ackerman, Louise M. Burke

Research outputs 2022 to 2026

Introduction: While an acute exercise session typically increases bone turnover markers (BTM), the impact of subsequent sessions and the interaction with pre-exercise calcium intake remains unclear despite the application to the ‘real life’ training of many competitive athletes. Methods: Using a randomized crossover design, elite male rowers (n = 16) completed two trials, a week apart, consisting of two 90-minute rowing ergometer sessions (Ex1, Ex2) separated by 150 minutes. Prior to each trial, participants consumed a high (CAL: ~1000 mg) or isocaloric low (CON: < 10 mg) calcium meal. Biochemical markers including parathyroid hormone: PTH; serum ionised calcium (iCa) and bone turnover markers (C-terminal telopeptide of type I collagen: β-CTX-I; osteocalcin: OC) were monitored from baseline to 3 hours post Ex2. Results: While each session caused perturbances of serum iCa, CAL maintained calcium concentrations above those of CON for most time points, 4.5 and 2.4 % higher post EX1 and EX2 respectively. The decrease in iCa in CON was associated with an elevation of blood PTH (p < 0.05) and β-CTX-I (p < 0.0001) over this period of repeated training sessions and their recovery, particularly during and after Ex2. Pre-exercise intake of calcium-rich foods lowered BTM over the course of a day with several training sessions. Conclusions: Pre-exercise intake of a calcium-rich meal prior to training sessions undertaken within the same day had a cumulative and prolonged effect on the stabilisation of blood iCa during exercise. In turn, this reduced the post-exercise PTH response, potentially attenuating the increase in markers of bone resorption. Such practical strategies may be integrated into the athlete’s overall sports nutrition plan, with the potential to safeguard long term bone health and reduce the risk of bone stress injuries.

Research outputs 2022 to 2026

High latency in teleoperation has a significant negative impact on operator performance. While deep learning has revolutionized many domains recently, it has not previously been applied to teleoperation enhancement. We propose a novel approach to predict video frames deep into the future using neural networks informed by synthetically generated optical flow information. This can be employed in teleoperated robotic systems that rely on video feeds for operator situational awareness. We have used the image-to-image translation technique as a basis for the prediction of future frames. The Pix2Pix conditional generative adversarial network (cGAN) has been selected as a base network. Optical …

Impact Of Work-Integrated Learning And Co-Curricular Activities On Graduate Labour Force Outcomes, Denise Jackson, Anna Rowe

Research outputs 2022 to 2026

The explicit linking of institutional funding to in-curricular industry engagement and graduate employment affirms the strategic importance of enhancing graduate employability in Australia. Key strategies to enhance graduate employability and employment outcomes are work-integrated learning (WIL) (where students engage with industry as part of their formal learning and assessment) and co-curricular activities (e.g. volunteering, leadership/award, and mentoring programmes), which are facilitated by the university but not embedded into curricula. While WIL is widely recognised for enhancing different aspects of student employability, the impact of co-curricular activities is less well-known. Further, there is a lack of empirical analysis on the nuanced …
