New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

Journal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.

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 ...
