Australia’s current wildfire crisis linked to colonial land-use change
The global wildfire crisis1 is often attributed to climate change, a framing that overlooks crucial historical drivers. Biomes at the forefront of this crisis, such as the temperate eucalypt forests of Australia, have seen alarming increases in large, intense wildfires in recent...

Reconstructing the history of the Antarctic Ice Sheet provides valuable insights into ice-sheet response to climate change. The Lambert Glacier-Amery Ice Shelf system is the largest glacial system in East Antarctica, but reconstructing the state of this glacier system is challeng...

For analysing karst hydrogeological systems, observations of karst springs and cave drips are considered indispensable. In addition to hydrometric observations, knowing the oxygen and hydrogen stable isotope ratios has improved the understanding of vadose zone and aquifer dynamic...

Self-adaptive layered oxide cathodes driven by charge reconfiguration for sodium-ion batteries
Abstract Layered oxide cathodes have attracted worldwide attention due to environmentally friendliness, structural diversity, and economic benefits. However, poor long-term cycling and unsatisfactory rate performance hinder the practical application. Hence, an oxide cathode with...

ABSTRACT Central Australia's ngarrawa, or ‘mound springs’, are unique hydrological systems that serve as some of the only near‐permanent sources of water and continuous sediment deposition in Australia's arid interior. As such, they hold significant potential as palaeo‐climate an...

T-Rex: the transportable radon-222 explorer for environmental or public health studies
We describe the development and testing of a “suitcase sized” 100 L two-filter dual flow-loop radon monitor, weighing ∼18 kg, flow rate ∼5 L min −1 , Rn-222 sensitivity ∼0.02 s −1 ∙(Bq∙m −3 ) −1 , temporal resolution 30-min, and operational range ∼0.3 – 30,000 Bq∙m −3 . Its porta...

Radiation biology on the ANTARES external micro-beam irradiation facility at ANSTO
Abstract This paper presents the observation of DNA double-strand breaks following irradiation using a new setup for cell culture exposure at the Australian Nuclear Science and Technology (ANSTO) External microBeam Irradiation Facility (EBIF). This facility represents the first c...

36Cl concentrations from polar ice cores set new constraints on the Carrington event.
The Carrington event of 1859 CE is considered one of the largest geomagnetic storms of the observational era and often used as a benchmark for a worst-case scenario. Yet, there exists no robust evidence of an associated solar energetic particle (SEP) event of a significant magnit...

Metal–Metal Interactions in Hexagonal Perovskites Containing Bimetallic Face-Sharing Bioctahedra
Abstract Recent studies have revealed metal-to-metal and intervalence-charge transfer transitions in cation ordered 6H perovskites with Cs3M+M2+M3+Cl9 stoichiometry. The structure and properties of two new members of this family, Cs3NaMnVCl9 and Cs3NaMnCrCl9, are reported here. I...

ABSTRACT Transition metal phosphides have attracted considerable attention as alternative conversion‐type anodes for SIBs because of their high specific capacities. However, their sodium‐storage mechanism typically shifts to an alloying reaction between P and Na + after the initi...

Wire Arc Additive Manufacturing (WAAM) of 316L generates complex thermal cycles, distortion and work hardening that are difficult to validate in 3D. Hence, in this paper, we design, build and fully characterise two benchmark walls (two-layer and three-layer) expressly for calibra...

The interaction between dissolved organic matter (DOM) and minerals governs OM stabilisation in soils. Heterogeneous composition of DOM and diverse mineral surface characteristics in soils make it challenging to determine reaction mechanisms at mineral-organic interfaces. To dete...

Abstract Al-containing perovskite oxynitrides, SrAl0.2M0.8O2.4N0.6 (M = Nb, Ta), were synthesized by ammonolysis of layered Sr5M4O15 precursors with α-Al2O3. This reaction demonstrates that the cation-insertion chemistry of layered-perovskite-derived oxynitrides can be extended t...
