Rare Earth Element Potential in the Araí Rift Metavolcanic, Central Brazil: Gamma‐Ray Signatures, Mineralogy and Exploration Implications

open access: yesTerra Nova, EarlyView.
ABSTRACT Although central Brazil hosts significant ion‐adsorption rare earth element (REE) deposits associated with A‐type granites, their coeval volcanic counterparts have been largely overlooked as exploration targets. This study demonstrates that acidic metavolcanic rocks of the Araí Group share strong radiometric, geochemical and mineralogical ...

Avian Eggshell Evolutionary Adaptations Inform Biomimetic Strategies for Next‑Generation Precision Cancer Theranostics

open access: yesAdvanced Oncology, Volume 1, Issue 1, December 2026.
ABSTRACT The avian eggshell is a sophisticated, multi‐functional biocomposite and, more importantly, an autonomous life‐support system evolved to safeguard embryonic development across dynamic and hostile environments. Discussing eggshell‐inspired biomaterials beyond simple structural imitation, this review translates these evolutionary survival ...

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

open access: yesAdvanced Functional Materials, Volume 36, Issue 81, 8 October 2026.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights
