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 ...

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.

Thiolate Salt Mediated Dynamic Silyl Ether Exchanges for Polymer Network Design and Deconstruction

Macromolecular Rapid Communications, EarlyView.
This work introduces thiolate salts as mediators for dynamic silyl ether exchange. This platform enables the synthesis of reprocessable covalent adaptable polymer networks (CANs) and allows for sterically controlled, and tunable deconstruction of silyl ether‐containing thermosets.

Predicting Mesoscopic Larmor Frequency Shifts in Ex Vivo Porcine Optic Nerve

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Larmor frequency shifts in white matter (WM) vary with fiber orientation due to anisotropic microstructure. Since clinical voxels are significantly larger than these microscopic frequency variations, the measured signal represents a bulk average of local shifts.

Weakly Convex Ridge Regularization for 3D Non‐Cartesian MRI Reconstruction

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose While highly accelerated non‐Cartesian acquisition protocols significantly reduce scan time, they often entail long reconstruction delays for 3D data. Deep learning–based reconstruction methods can alleviate this, but typically rely on complex, highly parametrized architectures.

Mechanical Recycling of Hybrid Polypropylene/Recycled Carbon Fiber/Hemp Composite Wall Panels: A Comparative Study of Compression and Injection Molding

Polymer Composites, EarlyView.
Mechanical recycling pathways for hybrid PP/rCF/hemp composite wall panels via compression and injection molding. ABSTRACT Circular economy increasingly influences sectors such as automotive, packaging, and building‐construction. The rise of circular economy in these sectors is driven by the generation of large volumes of waste that end up in landfills,

Fabrication of amorphous lamellar freestanding poly(N‐dodecyl acrylamide) films and their mechanical properties

Polymer International, EarlyView.
A freestanding film of completely uniaxially oriented amorphous lamellae was produced. The film exhibited enhanced tensile strength with increasing orientation of the lamella. Abstract An amorphous lamellar freestanding film composed of poly(N‐dodecyl acrylamide) (pDDA) was prepared by annealing a micrometer‐thick film under humid conditions (humid ...

Analysis of Detector-Source Distance and Detector Bias Voltage for Time Resolution of Plastic Scintillation Detectors

, 2020
The effects of the source-detector distance, the detector bias voltage variation and collimator usage on the time spectra of 133 Ba and 207 Bi calibrat ion sources were investigated through a spectrometer which was consisted of a BC400 type general ...

Implementation and preliminary evaluation of a practical digital workflow for routine laser‐radiation field coincidence quality assurance on the CyberKnife M6

Precision Radiation Oncology, EarlyView.
An MLC QA tool–QASC–CKQA workflow achieved the lowest laser‐radiation field coincidence deviations on CyberKnife M6, supporting a simpler, more reproducible routine QA strategy. When QASC is unavailable, the film‐based MLC QA tool workflow provides a practical alternative.
