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 4, April 2026.ABSTRACT The utilization of carbonaceous anodes in electrochemical systems, particularly potassium‐ion batteries (PIBs), remains hindered by sluggish kinetics and modest capacities, which are caused by the intrinsic ion storage mechanisms and constrained interlayer spacings.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT High‐capacity SiOx/graphite (SiO/G) anodes offer great potential for advancing lithium‐ion battery technology; however, their practical application is limited by low initial coulombic efficiency (ICE) and rapid capacity decay. These challenges primarily arise from unstable phase transitions and the formation of the solid electrolyte interphase

Cs2SnI6: A Perovskite‐Based Electromagnetic Wave Absorbing Material
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Lead halide perovskites and carbon‐based materials are interesting, high‐performing electromagnetic wave absorbing materials. However, only a few studies have been carried out to examine in detail the electromagnetic wave absorption properties of these materials.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Prelithiation is effective for compensating active lithium‐ion (Li+) loss in silicon (Si)‐based battery electrode materials. However, owing to the dynamic growth of the solid electrolyte interface (SEI), capacity fading remains the biggest challenge for the industrialization of Si electrodes.

Shuitu Baochi Xuebao, 2017 试验设置了对照（CK）、秸秆混匀（M-Str）、秸秆覆盖（Str）、生物质炭混匀（BC）和猪粪混匀（SM）5个处理，采用室内培养法研究有机物料种类与施用方式对红壤团聚体稳定性的影响。结果表明，秸秆混匀与猪粪处理下土壤有机碳（SOC）、热水溶性有机碳(HWC)、土壤抗破碎性和团聚体水稳定性(MWD)显著提高（p＜0.05），而秸秆覆盖对土壤有机碳和土壤团聚体形成的提升作用不明显（p＞0.05）。相对于对照处理，生物质炭提高了土壤有机碳含量，但对团聚体稳定性的影响不显著（p＞0.05 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Formic acid (FA) is considered to be a safe and convenient hydrogen source; however, achieving controlled and efficient FA dehydrogenation under mild conditions using stable solid catalysts remains a significant challenge. Pd‐based catalysts have been extensively studied due to their superior catalytic activity to other metal catalysts.
