When the Number Matters: Contextualising Australian Reference Values for 99ᵐTc‐Pertechnetate Thyroid Uptake

Journal of Medical Radiation Sciences, EarlyView.
Are the historical 1%–4% thyroid uptake reference values still valid in modern practice? This editorial examines why contemporary Australian and international data suggest otherwise and situates the new reference range reported by Wornes (https://doi.org/10.1002/jmrs.70078) and colleagues within the broader international literature.

Scintillation in the Arctic during the May 2024 Mother’s Day storm

Journal of Space Weather and Space Climate
The geomagnetic storm that started on May 10th 2024, often referred to as the “Mother’s Day” or “Gannon” storm, was the strongest storm for decades,with polar lights visible across significant parts of the globe.

Intercomparison of carbon‐13 and carbon‐14 tracer approaches for estimating marine calcification and net primary production

Limnology and Oceanography: Methods, EarlyView.
Abstract Accurate measurements of phytoplankton net primary production (NPP) and calcification are essential for quantifying marine carbon cycling, yet in situ calcification rates remain poorly constrained. We compared 13C‐ and 14C‐based tracer methods for NPP in laboratory cultures of the diatom Chaetoceros tenuissimus and the coccolithophore ...

Storage duration and water type determine the need for mercury chloride preservation of dissolved inorganic carbon

Limnology and Oceanography: Methods, EarlyView.
Abstract To quantify aquatic carbon budgets, it is important to accurately measure dissolved inorganic carbon (DIC). The standard approach requires the use of mercury chloride (HgCl2) poison to preserve samples, but the real need and overall constraints of using such a toxic compound remain elusive. Here, we evaluate the need for filtration and mercury

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

Archaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

Zero‐Dimensional Perovskite‐Inspired Scintillator‐Based High‐Radiation‐Resistant Radionuclide Analyzer Free From Irreversible Degradation

Laser &Photonics Reviews, EarlyView.
A zero‐dimensional perovskite‐inspired scintillator (Cs3Cu2I5) is developed as a high‐radiation‐resilient radionuclide analyzer capable of operating under extreme γ‐ray environments. Even after 200 kGy irradiation, the device fully restores its original spectroscopic performance through simple thermal annealing, demonstrating intrinsic defect ...

On the relationship between the geometrical control of scintillation indices and the data detrending problems observed at high latitudes

, 2007
The experimental estimate of radio waves scintillation, caused by plasma density irregularities in the ionosphere, is usually attempted by means of scintillation indices which are essentially standard deviations of stochasticly fluctuating parts of the

Host–Dopant Engineering of Ce4+‐Dominant Y3(Al,Ga)5O12:Ce,Mg Scintillators for High‐Performance X‐Ray Imaging

Laser &Photonics Reviews, EarlyView.
Mg2+ co‐doping strongly suppresses defect‐related emission and luminescence from trace impurities. Moreover, Mg2+ co‐doping improves the scintillation performance of Y3Al3Ga2O12:Ce by increasing the light yield and accelerating the decay time.

Zero‐Dimensional Organic–Inorganic Hybrid Metal Halides as Luminescent Materials: A Review From the Perspective of Molecular Level

Laser &Photonics Reviews, EarlyView.
Advances in zero‐dimensional organic–inorganic hybrid metal halides are reviewed from a molecular‐engineering perspective. Four design strategies (polyhedral‐architecture, elemental‐composition‐substitution, donor–acceptor/host–guest, multi‐emissive‐center integration‐coupling engineering) and structure‐performance trade‐offs are summarized.
