Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Through grain boundary segregation engineering, a crack‐free high‐strength CoCrNi medium‐entropy alloy (MEA) can be successfully fabricated via laser powder bed fusion (PBF‐LB). The influence of micron‐sized TiC particles on microstructural evolution, grain boundary segregation behavior, and mechanical properties was systematically ...

Functional Ecology, Volume 40, Issue 6, Page 1725-1739, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Metal‐doped carbon‐based nanomaterials (M‐CNM) play a strategically significant role in next‐generation precision antibacterial and antitumor therapies, as they integrate synergistic photothermal ablation, catalytic reactive oxygen species (ROS) generation, and multimodal imaging capabilities. However, their clinical translation is hindered by

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 This study demonstrates a new strategy for modifying the boron content to address stress‐relief cracking (SRC) in the 7CrMoVTiB10.10 alloy. First, coarse‐grained heat‐affected zone (CGHAZ) specimens with different boron contents were prepared via simulated welding thermal cycles.

Shuitu Baochi Xuebao, 2022 以建于1990年的新疆阜康荒漠生态系统观测研究站的长期施肥定位试验为平台，分析了不施肥（CK）、单施化肥（化肥常规NPK和化肥高量N2P2K）、化肥配施秸秆（化肥配施秸秆常规NPKS和化肥配施秸秆高量NPKS2）和化肥配施猪粪（NPKM）对农田土壤有机碳和无机碳含量与剖面分布及有机碳热稳定性的影响。结果表明：（1）长期施肥处理提高了土壤有机碳含量，其中耕层（0—20 cm）土壤有机碳响应最敏感，化肥配施秸秆还田处理下有机碳积累高于其他处理。（2）长期施肥处理均降低土壤有机碳稳定性 ...

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).
