Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Internal oxidation has been identified as an effective method for enhancing the strength of AgMg alloys. However, the concurrent occurrence of embrittlement remains inadequately understood, thus limiting their broader application. This study investigates the oxidation behavior of AgMg alloys with Mg concentrations ranging from 1 at% to 7 at ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT This study developed a FeSiAl@LMPGP composite material to address the demand for low‐frequency electromagnetic absorption. Through controllable heat treatment, FeSiAl particles and PbO nanoparticles self‐assembled into a high‐density Mott–Schottky heterointerface structure, which exhibited a significant built‐in electric field (BIEF) effect ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT SnTe is considered a potential alternative to PbTe for thermoelectric applications. However, excessive carrier concentration and thermal conductivity result in poor thermoelectric performance. Herein, p‐type SnTe‐based materials Sn0.8‐xMn0.1Pb0.1SbxTe were synthesized, and the combined effects of Sb, Mn, and Pb were systematically investigated.

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Organic‐inorganic metal halide perovskite solar cells (PSCs) are promising for photovoltaics due to their excellent optoelectronic properties. However, achieving high efficiency and stability remains challenging, mainly due to defects and energy losses at the electron transport layer (ETL)/perovskite interface.

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Dielectric ceramics are popular for energy storage materials because of their rapid charge–discharge characteristics, whereas their low energy density and efficiency hinder their miniaturization and integration. In this work, the energy storage performance is significantly enhanced through introducing Al2O3 and TiO2 into the 0.425(Bi0.5Na0.5 ...

Gallium‐Doped α‐MnO2 Cathode for High‐Performance Aqueous Zinc‐Ion Batteries
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Rechargeable aqueous zinc‐ion batteries (ZIBs) have received significant attention because of their high safety and low cost. MnO2 as a cathode material hampers the application of ZIBs due to its structural instability and dissolution during the operation of the battery.
