High‐Loaded Bismuth Oxide/Copper Silicone Rubber Composites and Their Application as Shielding Collar for I‐131 Treated Thyroid Cancer Patients

SPE Polymers, Volume 7, Issue 1, January 2026.
Development of high‐filler‐content silicone rubber composites containing up to 80 wt% bismuth oxide or copper, demonstrating significant I‐131 attenuation with retained flexibility and durability. ABSTRACT The development of flexible, non‐lead radiation‐shielding materials remains a critical challenge, particularly for I‐131 protection, where no ...

HST optical spectral index map of the jet of 3C 273 [PDF]

, 2001
We present HST images at 622 nm and 300 nm of the jet in 3C273 and determine the run of the optical spectral index at 0.2" along the jet. The smoothness of spectral index changes shows that the physical conditions are varying smoothly across the jet ...

A review on radiochromic film dosimetry in radiation therapy

Journal of Applied Clinical Medical Physics, Volume 26, Issue 12, December 2025.
Abstract Radiochromic films (RCFs) are ubiquitous in radiation oncology clinical and research settings to measure the radiation dose over a two‐dimensional (2D) area due to their high spatial resolution, water‐equivalency, and relative ease‐of‐use. Upon irradiation, the constituent monomers of the active layer of RCFs undergo polymerization, leading to

Type‐I Heterostructure CdZnS/ZnS Core/Shell Quantum Dots Scintillators for Stable, High‐Resolution, and Real‐Time X‐Ray Imaging

Advanced Science, Volume 12, Issue 48, December 29, 2025.
Ultra‐bright Cd0.27Zn0.73S/7 ML‐ZnS core/shell quantum dots exhibit a photoluminescence quantum yield exceeding 96% and a fourfold enhancement in radioluminescence intensity compared to CsPbBr3. Variable‐temperature photophysical analysis reveals that the narrowband emission originates from direct recombination of edge excitons.

Statistically Classified Marine Epifaunal Bioregions on the Southern Benguela Margin, South Africa

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Marine bioregional maps underpin management and conservation planning. Data‐driven maps based on robust statistical analyses that include uncertainty are new to the marine realm as more data becomes available. The use of Regions of Common Profile models on epifauna data from the Southern Benguela margin distinguished five bioregions related to low ...

Development of a Si/CdTe semiconductor Compton telescope

, 2004
We are developing a Compton telescope based on high resolution Si and CdTe imaging devices in order to obtain a high sensitivity astrophysical observation in sub-MeV gamma-ray region. In this paper, recent results from the prototype Si/CdTe semiconductor

Wildlife Law Enforcement's Use of “the Money Shot”: Creating a Visual Fallacy and Generating Wider Legal and Forensic Implications

WIREs Forensic Science, Volume 7, Issue 4, December 2025.
Suspected poachers and traffickers are frequently photographed holding or in close proximity to alleged evidence that is recovered at the time of their apprehension. These images are subsequently published online through various platforms prior to trial or conviction. Reproduced with permission, 2023, Simon Dures, all rights reserved.

Shallow estuarine reef as nursery habitat for Australasian snapper (Chrysophrys auratus)

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 4, Page 699-711, December 2025.
ABSTRACT Estuaries are important recruitment sites for many fish species, with structurally‐complex habitats such as subtidal seagrass beds on soft sediments particularly valuable due to their provision of food and shelter. Soft sediments dominate most estuaries, but where hard‐bottom reefs are present they have the potential to act as nursery habitats
