Reversible Dual‐Mode X‐Ray Memory Imaging of Photochromic Zero‐Dimensional Halide Perovskite Glass

open access: yesInformation &Functional Materials, EarlyView.
A photochromic halide perovskite glass with embedded Cs4PbBr6 nanocrystals enables reversible X‐ray–induced coloration and luminescence modulation, realizing dual‐mode X‐ray memory imaging with visual and photoluminescent readout. ABSTRACT Integrating photochromic and photoluminescence (PL) properties of halide perovskite glasses enables reversible ...

The Impact of Genetic Polymorphisms on Genotoxicity (DNA Damage) Among Children Exposed to Environmental Mutagens: A Systematic Review

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Children, as a particularly vulnerable group, are more susceptible to these mutagens due to their developing immune systems, higher physiological vulnerability, and increased exposure through behaviors like outdoor play and hand‐to‐mouth activities. This review aims to investigate the relationship between these environmental exposures, genetic

Determination of metals concentration in sedimentary profiles from lagoons affected by the tailings from the collapse of the Fundão dam

open access: yesBrazilian Journal of Radiation Sciences
The collapse of the Fundão dam in Mariana released more than 59 million m³ of tailings, which flowed almost 700 kilometers along the Doce river, through the states of Minas Gerais and Espírito Santo, reaching the estuary and into the Atlantic Ocean.

Comparative Evaluation of Four Stereotactic Radiosurgery Planning Approaches for Treatment of Posterior Choroidal Melanoma

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study evaluated four stereotactic radiosurgery planning approaches for posterior choroidal melanoma (CM). Analysis of thirteen CM cases resulted in a clinically meaningful reduction in dose to the brain for Brainlab Elements modulated arcs (BE) and Varian Eclipse HyperArc modulated arcs (HA) compared to Brainlab iPlan dynamic conformal arc therapy
