Multimodal Deep Learning‐Assisted Microstructural Evaluation System for Sintered NdFeB Magnets
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The performance of sintered NdFeB magnets, especially coercivity, is critically determined by their complex microstructure. However, a quantitative microstructural evaluation system (MES) is much needed but has long been missing in the community.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Ti3C2Tx MXene shows significant potential in the field of electromagnetic wave absorption; however, the wave absorption performance was hindered due to the impedance mismatch, which was caused by its inherent high dielectric constant. In this work, Ti3C2Tx MXene co‐assembled with molybdenum disulfide nanosheets and carbon coating layers (MXene/

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT High‐entropy oxides (HEOs) are promising for microwave absorption but suffer from a trade‐off between impedance matching and attenuation, often requiring high filling ratios (> 50 wt%). Herein, we propose a “lattice‐spin” dual‐regulation strategy by introducing giant‐radius Bi into a single‐phase HEO solid solution.

Kinetic‐Controlled Growth of Iron Chalcogenide Nanosheets Featuring Besnus Transition
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Two‐dimensional (2D) Fe‐based nanosheets have sparked wide attention owing to exotic magnetism, superconductivity and topological phases. However, the synthesis of 2D FemXn (X = Te/Se/S, m, n: integer), typically in a non‐stoichiometric ratio, remains challenging because of narrow thermodynamic windows.
