Owning Home, Finding Belonging: Relational Meanings of Homeownership for Migrant Healthcare Workers in Australia

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Migrant healthcare workers in Australia find themselves at the centre of three intersecting concerns, often presented as ‘crises’ in contemporary discourse: the ‘care crisis’, the ‘housing crisis’ and the ‘migration crisis.’ Yet their own perspectives on these issues are rarely foregrounded. This paper explores the role of homeownership in the

Dual Modality Semiconducting Polymer Nanoparticles for Use in Optical and Magnetic Resonance Imaging

open access: yesAdvanced NanoBiomed Research, EarlyView.
Well‐defined dual‐modality semiconducting polymer nanoparticles composed of red‐emitting conjugated polymers functionalized with novel gadolinium‐based contrast agents have been prepared. The assemblies show a greatly enhanced relaxivity performance compared to the clinical standard, Dotarem, while offering ultrabright fluorescence, ideal for optical ...

Exploratory Study on Carbon Dioxide Blends With Low‐GWP Working Fluids for Medium and High‐Temperature Heat Pumps Under Step Pressure

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates binary zeotropic mixtures of R744 (CO₂) blended with eco‐friendly refrigerants for medium‐high temperature heat pumps, comparing them with conventional R744/R134a systems. All mixtures meet 60–80 K temperature lift requirements under low‐temperature conditions. A genetic algorithm optimized system parameters using fixed

Quantum Carnot Bound from Petz Recovery Maps

open access: yesAdvanced Physics Research, EarlyView.
A quantum bound (ηP$\eta_P$, the Petz Limit) is derived for the efficiency (η$\eta$) of a heat engine utilizing two‐level quantum systems (qubits) as the working substance. This limit, based on Petz recovery maps, is stricter than the classical Carnot limit (ηC$\eta_C$) for irreversible cycles.
