A Review Of Natural Hydrogen Generation From Iron-Rich Rocks: Mechanisms, Influencing Factors, Techniques, And Knowledge Gaps, Kaveh Moghanirahimi, Lionel Esteban, Marina Pervukhina, Muhammad Arif, Stefan Iglauer, Alireza Keshavarz

Research outputs 2022 to 2026

Natural hydrogen has emerged as a promising clean energy resource with significant potential for large-scale subsurface production. Among the various geological sources, water–rock interactions involving iron-bearing rocks are among the most extensively studied pathways for natural hydrogen generation. This study provides a comprehensive review of hydrogen production from iron-rich lithologies, including mafic and ultramafic rocks, iron oxides, iron carbonates, and peralkaline granites. The fundamental mechanism involves the reduction of water coupled with the oxidation of ferrous iron to ferric iron under anoxic conditions. Key processes, including serpentinization, magnetite alteration, and siderite decomposition, are critically evaluated using experimental and modelling data. …

Women's Experiences Of Menstrual Pain And Perceptions Of Acupuncture: A Qualitative Study, Weiting Liu, Amanda Towell-Barnard, Khui Hung Lee

Research outputs 2022 to 2026

Introduction: Menstrual pain is a common reproductive health concern that can substantially disrupt physical, emotional, and social well-being, yet it is frequently normalised and insufficiently addressed within healthcare encounters. Acupuncture is increasingly used as a complementary approach for menstrual pain management; however, little qualitative research has explored how women understand, interpret, and navigate this option within their menstrual care.

Methods: A qualitative descriptive study was conducted using four online focus groups with 14 women aged 19–46 years residing in Australia who self-reported primary dysmenorrhea. Participants were purposively sampled from respondents to a previous cross-sectional survey study who had indicated willingness …

Research outputs 2022 to 2026

Nanoplastic (NP) fouling remains a key challenge for ultrafiltration (UF) membranes, yet systematic, controlled comparisons of how membrane functional groups govern NP-membrane interactions are still limited. Here, the role of membrane surface chemistry was systematically investigated using a controlled comparative framework based on plasma-grafted polyethersulfone (PES) UF membranes tailored with structurally comparable methacrylate monomers bearing distinct terminal functionalities, including mono-2-(methacryloyloxy)ethyl succinate (MMES, -COOH), N-[3-(dimethylamino)propyl] methacrylamide (DMAPMA, -N(CH3)2), and [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (SBMA, zwitterionic). Comprehensive characterisations supported successful surface grafting while preserving the membrane substructure. Fouling and separation were assessed using polystyrene (PS) NPs having different surface chemistries, i.e., PS, PS-COOH and …

Risks Of Mercury Release From Disturbance Of Blue Carbon Ecosystems, Fan Zhang, Jingrou Hu, Ana Carolina Ruiz-Fernández, Christian J. Sanders, Xinxin Li, Ruotong Chen, Kunshan Bao, Bigyan Neupane, Aidah Baloch, Yanhui Zheng, Oscar Serrano

Research outputs 2022 to 2026

Blue carbon ecosystems (BCEs) function as dual repositories of organic carbon and legacy contaminants. While BCEs are recognized carbon sinks, their role as mercury (Hg) sinks and the risk of their conversion into sources due to human and climatic disturbances remain unexplored. This review synthesizes current knowledge on the drivers and risks of contaminant remobilization from threatened BCEs, with a primary focus on mercury. We explore how natural and human disturbances influence Hg storage, release, and bioavailability, while evaluating the risks posed to ecosystems and human health. Through a three-level meta-analysis, we show that physical disturbance remobilizes approximately 54% (95% …

Shuvo Bakar, Lin Zhu, Helen Pilmore, William Mulley, Jennifer Li, Brian Nankivell, John Kanellis, Peter Nickerson, Chris Wiebe, Germaine Wong

Research outputs 2022 to 2026

Introduction: Microvascular inflammation (MVI) is a hallmark feature of antibody-mediated rejection (ABMR), but its prognostic significance when it occurs with T-cell-mediated rejection (TCMR) in the absence of other ABMR features remains unclear.

Methods: We examined the association between pure TCMR phenotypes, defined by the presence or absence of MVI, and graft survival using restricted mean survival time (RMST), and assessed interactions with rejection involving a “v” lesion.

Results: Among 1614 recipients with first biopsy-proven pure TCMR (2010–2023), 85% had no MVI, 8% subthreshold MVI (Banff glomerulitis [g] + peritubular capillaritis [ptc] = 1), and 7% with MVI (g + ptc …

Ph-Responsive Mixed-Charge Ultrafiltration Membranes For Adaptive Control Of Single And Mixed Nanoplastic Fouling, Mohadeseh Najafi, Javad Farahbakhsh, Roham Ghanbari, Ebrahim Mahmoudi, Michael Johns, Masoumeh Zargar

Research outputs 2022 to 2026

Nanoplastic (NP) fouling is an emerging barrier to the reliable application of ultrafiltration (UF) membranes, particularly in chemically complex waters where NP surface functionality governs deposition, cake formation, and cleaning performance. Herein, pH-responsive mixed-charge UF membranes were fabricated by plasma-induced graft copolymerisation of mono-2-(methacryloyloxy) ethyl succinate (MMES) and N-[3-(dimethylamino)propyl] methacrylamide (DMAPMA) onto poly(ethersulfone) (PES) to simultaneously regulate surface charge, hydration, and fouling reversibility. Unlike conventional single-charge or zwitterionic modifications, this approach enabled independent tuning of anionic and cationic moieties, generating composition-dependent and pH-switchable interfacial properties. ATR-FTIR, XPS, FESEM/EDX, AFM, WCA, streaming zeta potential, and MWCO analyses confirmed successful grafting, modified …

Marine heatwaves (MHWs) have emerged as an increasingly severe disturbance to global marine ecosystems, with documented intensifications in both frequency and magnitude over the past century. Western Australia has experienced some of the most severe MHWs on record, causing widespread ecological impacts, including coral bleaching and mortality, local species extinctions, and socioeconomic impacts such as fishery closures, making the region a critical case study of climate-driven change in the marine domain. Most recently, a severe MHW during summer 2024/2025 has caused widespread disruption to marine life, reinforcing the region's vulnerability to repeated extreme events. While extensive research has documented the …

Numerically Evaluating The Effect Of Pin Geometries On Interlayer Material Mixing And Thermo-Mechanical Characteristics During Additive Friction Stir Deposition (Afsd), Numan Habib, Ana Vafadar, Ferdinando Guzzomi

Research outputs 2022 to 2026

Additive Friction Stir Deposition (AFSD) is an additive manufacturing technique used to fabricate large-sized components layer-by-layer in a solid state, below the melting temperature. Poor interlayer mixing between subsequent layers results in a lack of mechanical interlocking, leading to low-strength components. The role of pin design plays a crucial role in fabricating high-strength components, requiring a comprehensive understanding of thermo-mechanical behaviour and flow pattern in the deposition zone. In this study, five different pin geometries are presented and investigated using a three-dimensional (3D) computational fluid dynamics (CFD) model. A user-defined function (UDF) was used to calculate strain- and temperature-dependent viscosity. …

Protocol For Integrating Vessel Networks And Environmental Matching To Inform Cost-Effective Archipelago Biosecurity Planning And Management, Chi T.U. Le, Chad L. Hewitt, Marnie L. Campbell

Research outputs 2022 to 2026

Inter-island vessel networks support economic activity but also enable secondary spread of non-native species. By integrating vessel-movement data, network analysis, and environmental matching, we present a protocol for generating a cost-effective biosecurity decision-support tool by assessing both the relative economic importance and the relative risks of species spread within a vessel traffic system. We outline steps for data curation, network construction, and sea surface temperature-based environmental similarity calculation. We then detail procedures for the translation of outputs into management recommendations. For complete details on the use and execution of this protocol, please refer to Campbell et al. ¹

Research outputs 2022 to 2026

This research examines the integration of a reverse Brayton cycle (RBC) used in a hydrogen liquefaction plant with a direct contact membrane distillation (DCMD) system for waste heat recovery and freshwater production. Waste heat from RBC compressors is used to run the DCMD plant, with parametric analysis evaluating the effect of feed Reynolds number, permeate mass flow rate, module length and pinch temperature of heat exchangers on thermal and economic performance of the hybrid system. Both parallel and series multi-stage DCMD configurations are compared with higher feed and permeate flow rates enhancing the temperature polarisation coefficient and permeate flux. A …

Kanmultisign: Multi-Scale Sequence-Based Pose Animation From Sign Language Notation With Kolmogorov-Arnold Networks, Guanyi Du, Lintao Wang, Kun Hu, Ziyang Wang

Research outputs 2022 to 2026

Sign language production from symbolic notation offers a scalable route to accessible sign animation. We present KANMultiSign, a multi-scale sequence generator that translates HamNoSys notation into two-dimensional human pose sequences. Our framework makes two complementary contributions. First, we introduce a coarse-to-fine generation strategy with multi-scale supervision: the model is first guided by an intermediate body–hand–face scaffold to encourage global structural coherence, and then refines fine-grained hand articulation to improve finger-level detail. Second, we investigate integrating Kolmogorov–Arnold Network modules into a Transformer backbone, using learnable univariate function primitives to model the highly non-linear mapping from discrete phonological symbols to continuous body …

Experimental Investigation Of Factors Affecting Natural Magnetite Wettability: Implications For Geological Hydrogen Generation And Storage, Kaveh Moghanirahimi, Lionel Esteban, Valeriya Shulakova, Stefan Iglauer, Alireza Keshavarz

Research outputs 2022 to 2026

Natural magnetite in Banded Iron Formations (BIFs) is attracting interest as a hydrothermal H2-generating medium and a potential caprock for subsurface hydrogen storage because of its low permeability. However, its wettability under reservoir conditions remains poorly understood. In this study, the wettability of natural and organically aged magnetite was evaluated using the tilted plate contact angle method at 1–100 bar and 25–65 °C with deionized water and 5 and 10 wt% NaCl brines as droplet fluids. The results showed that magnetite remained water-wet throughout the tested conditions. Higher pressure shifted the system toward less water-wet behaviour, whereas increasing temperature enhanced …

For over 40 years, First Nations communities in Australia have called for community-controlled birthing and maternal–infant health programs that restore First Nations-led, community-controlled birthing systems grounded in cultural authority and sovereignty. ‘Birthing on Country’ services have demonstrated improved First Nations maternal–infant health outcomes, more babies kept out of the child protection system, and reduced health system costs. Restoration and expansion of Birthing on Country services across regions has been inconsistent, and has lacked support for national implementation. In 2022, a large national gathering (‘Best Start to Life’) was co-hosted in Mparntwe (Alice Springs). The focus was Birthing on Country service …

A Novel Mesoscopic Modelling Approach For Steel Fibre-Reinforced Concrete: Investigating The Effects Of Fibre Alignment On Flexural Performance, Ayman Mansour, Themelina Paraskeva, Nuha S. Mashaan

Research outputs 2022 to 2026

Traditional finite element modelling of Steel Fibre-Reinforced Concrete (SFRC) relies on homogenised macroscopic models that overlook localised effects such as fibre orientation. Although three-dimensional (3D) mesoscopic frameworks for SFRC have been developed, direct comparisons with homogenised macroscopic models under the EN 14651 flexural test configuration remain limited, particularly for variations in fibre orientations. Consequently, a comparative evaluation is essential to assess the mesoscopic model under EN 14651 conditions. To address this, this work introduces a 3D tensor-controlled mesoscopic modelling approach for SFRC that explicitly simulates individual fibres with random and preferential alignment, offering a more realistic representation of fibre bridging …

Research outputs 2022 to 2026

Prehospital emergency care requires clinicians to manage a vast array of medical and trauma incidents, including rare events such as obstetrics (i.e., childbirth) emergencies. Emergency births can have life-threatening complications such as neonatal respiratory distress potentially leading to cardiopulmonary resuscitation. Management of low-frequency high-risk (LFHR) events such as birthing and immediate neonatal care occurring outside the planned place of birth require expert clinical management. Underutilised skill and knowledge of LFHR events decay within 12-months of being taught. LFHR events are often overlooked for refresher training due to the low occurrence of such cases, putting LFHR patients at even greater risk …

Reappraisal Of Adverse Weather As A Catalyst For Special Tourism Experiences, Valério Souza-Neto, Brent Moyle, Yawei Jiang, Gui Lohmann

Research outputs 2022 to 2026

On any given day millions of travellers find themselves contending with weather that deviates dramatically from prior expectations. Traditionally regarded as an unwelcome disruption, adverse weather has rarely been examined for its potential to enrich, rather than diminish, the value of tourist experiences. Consequently, this research critically explores how tourists positively reappraise adverse weather disruptions in tourism experiences. Based on eight focus groups (n = 42), transcript data were analysed using reflexive thematic analysis within a social-constructivist paradigm, combining iterative coding with abductive reasoning. Findings demonstrate that adverse weather can function as a situational catalyst that enables tourists to reinterpret …

This qualitative study examined the experience of 19 community-based health promotion practitioners in Western …

Adjusting To Extreme Demand Volatility: A Comparative Analysis Of Air Navigation Service Provider Financial Resilience In The Southern Asia-Pacific, Margaret Arblaster, Gui Lohmann

Research outputs 2022 to 2026

Air navigation service providers fund their operations almost entirely through activity-based user charges, creating a structural dependency between revenue and air traffic volume. When traffic collapses, revenue falls immediately, but the cost base, dominated by specialised labour under fixed-term employment contracts and long-lived capital infrastructure, adjusts slowly, if at all. This paper examines how five corporatised, wholly government-owned air navigation service providers in the southern Asia-Pacific (i.e., Airservices Australia, Airways New Zealand, AirNav Indonesia, NiuSky Pacific in Papua New Guinea, and Fiji Airports) responded to the extreme demand shock of the COVID-19 pandemic and assesses the role of government grants …
