Adelaide Research & Scholarship
Adelaide Research & Scholarship (AR&S) is the University of Adelaide’s digital repository. AR&S provides a platform for the collection, organisation, access and preservation of the research and scholarly outputs of the University community in digital formats, as well as digital management of information in physical formats.
University of Adelaide higher degree by research theses are deposited into the AR&S Theses community as part of the final thesis lodgement process.
AR&S also serves as the home of the digital collections of University Library Archives and Special Collections. Items include digitized representations of physical items, such as photographs and full texts, and digital-born materials, allowing worldwide access to our heritage and research collections.

The Effectiveness of the Use of Silver Fluoride and Teledentistry to Manage and Prevent Childhood Caries Among Aboriginal Children in Remote Communities: Protocol for a Cluster Randomized Controlled Trial
(JMIR Publications, 2025) Arrow, P.; Piggott, S.; Anderson, L.; Bessarab, D.; Jamieson, L.; Atkinson, D.; Ngo, H.; Kularatna, S.; Tonmukayakul, U.; Nanda, S.; Patel, J.; Powell, L.; Estai, M.
Background: Australian Aboriginal children experience dental decay at more than twice the rate of non-Aboriginal children. The Select Committee into the Provision of and Access to Dental Services in Australia noted that the rate of potentially preventable hospitalizations was the highest among children aged between 5 and 9 years and was higher among Indigenous Australians and those living in remote locations. The application of a silver fluoride (AgF) solution to decayed surfaces has been shown to be effective in stopping the decay process and reducing the occurrence of new decay but has been tested to a limited extent in the Australian context. Objective: This study aims to evaluate the feasibility of using the skills of an Aboriginal health practitioner to undertake the application of AgF to carious primary molars to arrest the caries progression and prevent the occurrence of new caries among young Aboriginal children in remote communities. Methods: This study is a cluster-randomized controlled trial with communities randomized and stratified based on caries level and water fluoridation status. The trial will recruit 640 children (aged between 6 months and 7 years) from 30 communities. Informed consent will be obtained. At baseline, each child in the intervention group will be examined by a calibrated examiner and subsequently by an oral health practitioner who will prescribe to an Aboriginal health practitioner the teeth to be treated with AgF. A formulation with 38% AgF will be applied for 1 minute (0.004 mL per tooth). The control group will be provided with standard minimally invasive care. Participants will be followed annually for 2 years to assess caries arrest and prevention by blinded calibrated examiners. Child oral health–related quality of life and dental anxiety will be elicited through validated questionnaires. Tests of proportions will be used to evaluate the proportion of lesions arrested and the proportion of surfaces at risk that decayed over the follow-up. Multiple logistic regression with appropriate control for clustering of teeth and communities will be used to evaluate caries arrest, controlling for potential confounding factors. Results: Community engagement has commenced, and data collection protocols have been prepared. Staff specific to the study (eg, Aboriginal health practitioners or workers) are in the process of recruitment. Participant recruitment will commence in March 2026 and conclude in December 2026. Study outcomes will be reported at 12- and 24-month follow-ups. Conclusions: This study will test the effectiveness and feasibility of a non-oral health professional applying AgF to achieve caries arrest and prevention and validate clinical findings against digital imagery acquired on site. This pragmatic study will inform the development of suitable and accessible models of care for dental service provision in rural and remote communities in Australia.

Trends in cardiometabolic conditions and pregnancy outcomes: a retrospective cohort study in South-Eastern Melbourne
(BMJ Publishing Group, 2025) Belsti, Y.; Palmer, K.R.; Moran, L.J.; Rolnik, D.L.; Goldstein, R.; Mousa, A.; Enticott, J.; Teede, H.J.
Objectives To examine trends in preconception and pregnancy cardiometabolic risk factors and conditions, pregnancy and birth complications, obstetric interventions, and the impact of COVID-19, and to forecast future disease burden. Design A multi-centre retrospective cohort study. Setting A large hospital network with three maternity hospitals serving ethnically diverse populations in Melbourne, Australia. Participants Pregnant women who gave birth between 2016 and 2022. Outcome measures Trends in cardiometabolic conditions, birth complications and obstetric interventions. Results Over 7 years, 63 232 women were included, of whom 40% were nulliparous, and 60.9% were born overseas from 167 countries. From 2016–2022, maternal age (30.2–31.3 years), obesity (21.0%–26.2%), gestational diabetes mellitus (GDM) (15.9%–28.1%) and caesarean delivery (28.5%–37.6%) increased, while average gestational weight gain, premature births and special care admissions declined from 12.6–11.6 kg, 6.3%–4.9% and 24.2%–14.1%, respectively; and was statistically significant (p<0.05). Hypertensive disorders of pregnancy remained stable, fluctuating slightly (6.5% in 2016, 7.6% in 2020, 6.9% in 2022). During the COVID-19 lockdown period, the odds of GDM and induced birth increased by 8.0%, whereas the odds of caesarean section decreased by 5.0%. GDM is forecast to reach 43.0% by 2028. Conclusions Prepregnancy and pregnancy cardiometabolic risk factors and conditions, pregnancy and birth complications, and obstetric interventions increased markedly over 7 years. Despite this, offspring complications, including special care admissions, stillbirths and prematurity, decreased, while pregnancy complications peaked during COVID-19. GDM is forecasted to increase to 43.0% by 2028, posing an unsustainable health and economic burden that necessitates urgent public health initiatives.
Triplet Sulfur Radical Pairs Stabilized through Hund's Rule for Ultrafast Lithium-Sulfur Batteries
(American Chemical Society, 2025) Li, H.; Meng, R.; Thomsen, L.; Zhong, S.; Ye, C.; Tadich, A.; Qiao, S.-Z.
Sulfur radicals are highly reactive intermediates that can greatly accelerate reaction kinetics in lithium–sulfur batteries. However, the intrinsic instability restricts their applications. Herein, we reveal and validate the formation of ultrastable triplet sulfur radical pairs ([Sₓ·‾ – Sₓ·‾], x = 2, 3, 4) by combining electron paramagnetic resonance and synchrotron radiations. These radical pairs are produced during the spontaneous decomposition of polysulfide molecules on ferrimagnetic surface, where the sulfur radicals adopt parallel spin alignment and pair into stable triplet states through Hund’s Rule. These radicals enable exceptionally rapid sulfur conversion, delivering a 100-fold kinetic enhancement compared to the traditional polysulfide molecules. Using these triplet radical pairs, the lithium–sulfur battery achieves a remarkable discharge capacity of 728 mAh g‾¹, even at an ultrahigh current rate of 8.0 C, with high sulfur loading and lean electrolyte. Significantly, this is the highest capacity under ultrafast charge–discharge rates reported to date.
Using neutron stars to probe dark matter charged under a Lµ − Lτ symmetry
(IOP Publishing, 2025) Bell, N.F.; Busoni, G.; Ghosh, A.
Kinetic heating of old cold neutron stars, via the scattering of dark matter with matter in the star, provides a promising way to probe the nature of dark matter interactions. We consider a dark matter candidate that is a Standard Model singlet Dirac fermion, charged under a U(1)Lμ-Lτ symmetry. Such dark matter interacts with quarks and electrons only via loop-induced couplings, and hence is weakly constrained by direct-detection experiments and cosmic-microwave background observations. However, tree-level interactions with muons enable the dark matter to interact efficiently with the relativistic muon component of a neutron star, heating the star substantially. Using a fully relativistic approach for dark matter capture in the star, we show that observations of old cold neutron stars can probe a substantial, yet unexplored, region of parameter space for dark matter masses in the range 100 MeV - 100 GeV.
