Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films
This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Abstract This paper examines how an International Atomic Energy Agency (IAEA) expert mission for technical assistance in the late 1950s to Greece was effectively transformed into a mission to achieve the IAEA′s central objective: to consolidate its position as the leading global authority on radiation protection. The study focuses on the work of Alfred

Lead‐free transparent nanocomposite for efficient clinical X‐ray shielding
A lead‐free nanocomposite of LaF3 nanoparticles exhibits a high optical transparency of 86% with a heavy loading of up to 70 wt%, which enables the design of radiation shielding goggles for interventional surgeons in real clinical scenarios. Abstract The increasing use of X‐ray imaging in the medical field has generated a growing need for efficient ...
