Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The inherent brittleness of hardmetals stems from the rigid covalent bond in the ceramic matrix and the sharp ceramic/metal interface, which restricts the nucleation and motion of dislocations. In this study, a novel strategy is proposed to activate significant dislocation behaviors in the WC matrix by employing a non‐equiatomic CoNiFeCr ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Arsenic presents a critical duality as both a hazardous environmental pollutant and an indispensable material for advanced semiconductor technologies. This study proposes an integrated reductive vacuum sublimation strategy, assisted by carbon and lead additives, to purify crude arsenic containing high oxygen (7.4%) and antimony (1326 mg kg−1).

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Atomically dispersed iron–nitrogen–carbon (Fe‐N‐C) catalysts have emerged as promising alternatives for oxygen reduction reaction (ORR) owing to their highly atomic utilization. However, maintaining both Fe atomic dispersion and dense Fe‐Nx sites (typically below 2 wt%) in Fe‐N‐C catalysts is still a key challenge.
