In Situ Uniform Lithium Enrichment for Dense, High‐Performance LLZO Solid Electrolytes
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT A major challenge in garnet‐type Li7La3Zr2O12 (LLZO) system all‐solid‐state electrolytes is the high porosity that typically remains after sintering, which compromises ionic conductivity and degrades battery cycling performance. To address this, we propose an innovative strategy to achieve uniform lithium enrichment on the surface of ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Metal oxide semiconductor‐supported noble metal nanoparticles are common sensing materials for gas sensors. However, the large size and their tendency to migrate at high temperatures often lead to inferior sensing sensitivity and stability. Herein, a salt‐assistant strategy is developed to prepare fully‐exposed Ir clusters on SnO2 nanorods ...

Highly Stable CsPbBr3@Cs4PbBr6 Perovskite Fluorescent Nanomaterials for White Light‐Emitting Diodes
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Although halide perovskite nanocrystals exhibit excellent photoelectric properties, their inherent instability greatly limits their practical applications. Here, we report a novel self‐assembly strategy to synthesize highly stable CsPbBr3@Cs4PbBr6 perovskite fluorescent nanomaterials in a single step by using 4,4′‐azo (4‐cyanoglutaric acid, CA)
