Orchestrating Anion–π+ Interactions to Accelerate Metal‐Free Room‐Temperature Phosphorescence

open access: yesAngewandte Chemie, Volume 138, Issue 43, 19 October 2026.
Tuning anion–π+ interactions in pyridinium iodide contact ion pairs enables ultrafast metal‐free room‐temperature phosphorescence (540–605 nm) with radiative rates up to 5.2×105 s−1. Strong iodide→π+ charge‐transfer coupling, enhanced spin–orbit interactions, and dynamic ion‐pair organization accelerate intersystem crossing and emission, establishing ...

Neuronal Overexpression of Glycogen Synthase Kinase‐3β Accelerates Age‐Related Glial, Vascular, and Inflammatory Remodeling of the Murine Dentate Gyrus

open access: yesGlia, Volume 74, Issue 12, December 2026.
Aging induces layer‐specific changes in glial populations and vascular organization across the dentate gyrus. Neuronal GSK‐3β overexpression accelerates age‐related remodeling of the dentate gyrus neurogenic niche. GSK‐3β‐overexpressing mice show premature subgranular zone (SGZ) astrocyte loss, altered microglia and oligodendroglia, and vascular ...

Nonlinear Response of Plastic Scintillator under High-dose-rate Soft X-ray Irradiation

open access: yesYuanzineng kexue jishu
Accurate quantitative diagnosis of pulsed radiation fields, particularly soft X-rays, relies heavily on the linear response of detection materials. Plastic scintillators are widely employed in such diagnostics, especially for inertial confinement fusion (

Drought Dominates Engineered Lipid Sink Effects on Sorghum Physiology and Carbon Allocation

open access: yesGCB Bioenergy, Volume 18, Issue 12, December 2026.
Drought dominated carbon allocation responses in oil‐enhanced sorghum, overriding most effects of engineered lipid sinks on belowground carbon partitioning. Using whole‐plant 13CO2 labeling, we show that drought reorganizes vertical carbon allocation by reducing deep‐root carbon incorporation while increasing deep rhizosphere 13C enrichment.

Observation of relativistic rise in the energy loss in plastic scintillator

open access: yes, 1973
In comparing pulse height spectra from protons of momentum 13 GeV/c and 20 GeV/c a rise of (1.54+or-0.29) % in the average energy loss in plastic scintillator has been observed. (2 refs)

Characterization and performance evaluation of epoxy-based plastic scintillators for gamma ray detection

open access: yesFrontiers in Physics
This research investigates the fabrication and analysis of plastic scintillators using an epoxy matrix. Plastic scintillators are widely used in radiation detection because of their low cost, ease of fabrication, resistance to moisture, and rapid decay ...

Sampling calorimeter to measure the photon’s incident angle [PDF]

open access: yesEPJ Web of Conferences
A three-dimensional fine-segmented sampling calorimeter enables us to measure the profiles of generated shower particles along the photon’s direction. For a feasibility study, a toy detector was designed via Geant4 simulation.

New Fluorescent Compounds for Plastic Scintillator Applications Submitted to Nuclear Instruments and Methods New Fluorescent Compounds for Plastic Scintillator Applications

open access: yes, 2020
The fluorescent compound 3-hydroxyflavone (3HF) has been modified in order to study the resulting structure-fluorescence relationship. A series of twelve derivatives, bearing different substituents at various positions on the phenyl ring, has been ...
