Electrically Switchable Altermagnetism in Monolayer MoCl3
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Altermagnets intertwine spin‐split bands with vanishing net magnetization, offering great potential for high‐density, stray‐field‐free spintronic devices. However, their development is hindered by both material scarcity and difficulties in external control due to their intrinsic symmetry protection.

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT The performance optimization of ultrahigh‐strength Cu‐15Ni‐8Sn alloy relies on controlling recrystallization and aging precipitation, which are two thermally activated processes constrained by high activation barriers. Conventional heat treatment requires elevated temperatures and prolonged holding time, inevitably leading to grain coarsening ...

Accessing Ultra‐Nano Phase‐Separated Metallic Glasses via Cryogenic Cycling
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Phase separation offers a promising avenue to mitigate the inherent brittleness of metallic glasses. However, traditional approaches relying on mixing enthalpy face significant challenges, primarily due to the detrimental impact on glass‐forming ability.

Shuitu Baochi Xuebao, 2022 为探究玉米秸秆粉碎还田对黑土坡面土壤侵蚀特征的影响,对不同坡度(3°,5°和7°)下不同玉米秸秆粉碎还田量(0,25%,50%,75%和100%)坡面进行人工模拟降雨试验。结果表明:玉米秸秆粉碎还田措施具有调控径流作用,坡面产流时间延缓,产流率和径流量降低;秸秆还田量越大,产流时间延后越明显,平均径流流速越低;在3°坡面,秸秆粉碎还田25%和100%处理的调控径流效果较好,在5°和7°坡面,秸秆粉碎还田50%和75%处理的调控径流效果较好。同时 ...

Research Progress and Prospect of Single‐Atom Materials in Tumor Catalytic Therapy
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Tumor catalytic therapy (TCT), an emerging therapeutic modality, exerts specific cytotoxic effects on tumor cells by catalyzing endogenous substances within the tumor microenvironment (TME)—including hydrogen peroxide (H2O2), glucose, and glutathione—to generate reactive oxygen species (ROS) or deplete protective biomolecules.
