Yttrium Addition Co‐Enhances the Plasticity and Corrosion Resistance of TiB2‐Refined Al‐Mg‐Zn Alloys
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT To address the degradation of corrosion resistance induced by Al‐5Ti‐B grain refiner during the strengthening of Al‐Mg‐Zn alloys, this study innovatively employed a rare earth element yttrium (Y) alloying strategy to achieve synergistic enhancement of mechanical strength and corrosion resistance.

Shuitu Baochi Xuebao, 2020 采用原状土冲刷水槽法和静水崩解法测定土壤抗冲性和抗蚀性，以云冷杉红松林（PA）和椴树红松林（TP）的林隙和郁闭林分为对照，分析了小兴安岭地区2种林型由掘根倒木形成的不同丘和坑微立地类型及其土壤性质对土壤抗冲性和抗蚀性的影响，旨在揭示它们与土壤抗侵蚀能力的关系。结果表明：在2种林型下由掘根倒木形成的丘和坑微立地上，土壤砂粒含量均较高，其抗侵蚀能力均较弱，而对照却相反；2种林型下丘和坑微立地的土壤容重均与土壤抗冲性和抗蚀性呈无显著的负相关（P>0.05），而PA对照的土壤容重与它们均呈不显著正相关（P>0 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT The central challenge in the development of high‐performance electromagnetic wave‐absorbing materials lies in achieving an optimal balance between impedance matching and attenuation characteristics. This is particularly critical for purely dielectric absorbers, where precise tailoring of the real (ε′) and imaginary (ε″) parts of the complex ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Vanadium oxides are deemed competitive cathode candidates for aqueous zinc‐ion batteries (AZIBs), benefited from their high theoretical capacity and multiple crystalline structures. However, the sluggish reaction kinetics, poor reversibility, and high solubility have hindered the practical application.

Highly Stable CsPbBr3@Cs4PbBr6 Perovskite Fluorescent Nanomaterials for White Light‐Emitting Diodes
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Although halide perovskite nanocrystals exhibit excellent photoelectric properties, their inherent instability greatly limits their practical applications. Here, we report a novel self‐assembly strategy to synthesize highly stable CsPbBr3@Cs4PbBr6 perovskite fluorescent nanomaterials in a single step by using 4,4′‐azo (4‐cyanoglutaric acid, CA)

Review of Policy Research, Volume 43, Issue 1, January 2026.Abstract Populist radical right parties are on the rise all over Europe. Recent literature investigates their effects on environmental policy, however, often applying an overly broad perspective on the policy area and neglecting causal mechanisms. This article addresses both gaps in an in‐depth case study of partisan effects on Swedish environmental ...
