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 ...

Low‐Temperature Experimental Characterization of Magnetite‐Based Rock‐Bed Thermal Battery

open access: yesEnergy Storage, Volume 8, Issue 8, December 2026.
The graphical abstract illustrates the proposed low‐temperature magnetite‐based rock‐bed thermal energy storage (RTES) concept for greenhouse applications and the corresponding experimental configuration. During charging, thermal energy is transferred from solar collectors to the RTES and is stored as sensible heat. During discharge, the stored heat is

Permian sedimentary sequence containing analcimolite and authigenic aegirine from the Boskovice Basin (Bohemian Massif, Czechia)

open access: yesThe Depositional Record, Volume 12, Issue 5, November 2026.
The Permian freshwater lacustrine sedimentary sequence rich in analcime, with unusual authigenic aegirine and NaFe3+ clinopyroxene. Product of ashfall directly linked with fossil accumulation (Konzentrat‐Lagerstätte). Abstract The Early Permian freshwater lacustrine sedimentary sequence in the vicinity of Bačov (Czechia) is world‐famous for its rich ...

Orientation‐Dependent Surface Stoichiometry and Electronic Properties of ZnFe2O4 Thin Film Photoanodes

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 6, November 2026.
Crystallographic orientation strongly influences the surface stoichiometry and interfacial electronic behavior of ZnFe2O4 thin film photoanodes grown by pulsed laser deposition. The (111) orientation exhibits greater Zn depletion, Fe enrichment, rectifying local current–voltage behavior, and a more positive water‐oxidation onset potential than the (110)

Machine Learning and Structural Analysis for Generation‐Wise Selection of Perylene Diimide Dendrimers Based on Topological Compatibility With Drug Molecules

open access: yesChemistryOpen, Volume 15, Issue 11, November 2026.
Machine learning and graph‐theoretic descriptors are integrated to evaluate topology‐based compatibility between perylene diimide‐core dendrimer generations and antiviral, antioxidant, and imaging agents. Standardized structural similarity reveals generation‐dependent compatibility patterns, while Gaussian process regression uncovers key structure ...
