Unveiling Solidification Mechanism and Balanced Strength–Ductility Synergy of Eutectic High‐Entropy Alloys

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Eutectic high‐entropy alloys (EHEAs) have attracted significant attention due to their balanced mechanical properties and promising applications. Nonetheless, the correlation between the solidification mechanism of eutectic microstructures and their mechanical properties remains elusive.

The Challenge of Icy Sample Return Begins With Artemis

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Throughout the Solar System, volatiles are found as solid ices. Returning ices to Earth for scientific analysis is critical to understanding the formation of a Solar System that bears life. This challenge begins with the Artemis missions to the lunar south polar region, where the coldest lunar regolith is enriched in H2O and other ices—systems

Fabrication‐Driven Oxidation Pathways in Y/Hf‐Modified High‐Entropy Alloys: From Elemental Segregation to Oxide Homogeneity

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT This study elucidates the oxidation mechanisms governing Y/Hf‐doped AlCoCrFeNiTi high‐entropy alloys (HEAs) and reveals the pivotal role of fabrication processes in dictating high‐temperature oxidation behavior. We demonstrate that casting and spark plasma sintering (SPS) promote Y/Hf segregation, resulting in heterogeneous oxide formation and

Integration of Laser‐Patterned Photonic Crystals in Si Solar Cells

Advanced Optical Materials, Volume 13, Issue 35, December 12, 2025.
Photonic crystal textures are integrated into silicon solar cells using laser‐patterned alumina masks and plasma etching. An isotropic defect‐removal process preserves surface passivation and optical quality, enabling 23.1% efficiency. This scalable process with periodically anchored masks and Bessel‐beam patterning marks an important step toward ...
