Strong Coupling in Bulk Nanoplasmonic Nanoplatelet Perovskite Scintillators. [PDF]

open access: yesAdv Mater
A bulk scintillating nanocomposite is engineered from CsPbBr3 nanoplatelets and Ag nanocubes to support exciton–plasmon strong coupling under X‐ray excitation. The resulting hybrid polaritonic states appear directly in radioluminescence, opening a route toward polariton‐enabled scintillator design beyond conventional Purcell enhancement.

Manipulation of organic triplet states for achieving multifunctional luminescence: Mechanisms, strategies, and applications

open access: yesFlexMat, EarlyView.
Triplet‐state regulation strategy involves the relaxation pathways of triplet excitons and the underneath structure property relationships. This review combines recent studies on relaxation principles, energy transfer, anti‐Kasha behaviors, and functional applications of triplet excitons.

Hypervision Proton Surgery: The Future Direction of Proton Therapy

open access: yesiNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

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

open access: yesJournal 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.

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

open access: yesLimnology 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 ...

Halide Scintillators

open access: yes, 2003
Scintillators have been used for decades to make ionising radiation visible. Either by direct observation of the light flash produced by the material when it is exposed to radiation, or indirect by use of a photomultiplier tube or photodiode. Despite the

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

open access: yesLimnology 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

Defect engineering in Mg2+ co-doped LuAG:Ce ceramics: Towards ultrahigh fast scintillation proportion

open access: yesJournal of Advanced Ceramics
A slow scintillation component due to charge carrier capture at point defects is a serious issue in scintillator materials. Therefore, the fabrication of scintillators with a high proportion of fast components in the scintillation response is of great ...
