Glycerophosphocholine‐Mediated Dual Regulation for Highly Stable Aqueous Iron‐Ion Batteries
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Iron‐ion batteries (FeIB) offer the advantages of low cost and high capacity, demonstrating potential for large‐scale energy storage. However, severe hydrogen evolution reaction (HER) occurs during cycling, which significantly impacts battery lifespan.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT In Co‐based alloys, the γ phase is normally stable at high temperatures and the ε phase at low temperatures, and there is a martensitic transition on cooling to ∼417°C. In the γ/β dual‐phase CoCrAlY bond coat of turbine blade thermal barrier coating systems, we observed the opposite: γ remained stable at room temperature, yet it underwent a γ →

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Due to their exceptional porosity, structural versatility, and modular coordination chemistry, metal–organic frameworks (MOFs) have emerged as versatile platforms for targeted drug delivery. These structures enable fine‐tuning of pore size, surface activity, and framework stability for the encapsulation of a broad range of therapeutics ...

Self-assembly of linear triblock copolymers confined by lattice-type films(线性三嵌段共聚物格点薄膜受限下的自组装)
Zhejiang Daxue xuebao. Lixue ban, 2018 采用实空间自洽场理论研究了线性三嵌段共聚物在格点薄膜受限下的自组装.根据受限空间内共聚物的自组装情况，描绘了不同嵌段比下共聚物的三角相图，分析各相结构的形成机理，并详细观察三色层状与核壳柱状之间的相变过程.在受限的基础上，通过在薄膜表面施加格点型吸附势，获得了 一系列聚合物微结构，发现层状结构是最稳定的相结构；当吸附强度增大时，各嵌段的自组装结构发生变化，三色层逐渐打破稳定的平行状态，转变为编织层状.当嵌段比处于某特殊范围时，聚合物还形成了新颖的球-柱结构.研究结果可为制备稳定的新型材料提供理论方案.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Ultrathin, lightweight, and mechanically compliant electromagnetic interference (EMI) shields are increasingly required for high‐frequency electronic devices. However, conventional metallic shields predominantly rely on conductivity‐driven reflection mechanisms, which become ineffective at reduced thickness and may cause severe secondary ...

Shuitu Baochi Xuebao目的团聚体是土壤肥力的重要指标，其稳定性直接影响土壤物理、化学和生物特性。在盐碱化条件下，团聚体受到土壤高盐分或强碱性的影响，易导致土壤结构退化和功能降低，严重限制农业生产。旨在总结盐碱土与非盐碱土团聚体的差异，分析盐碱化条件下影响团聚体形成和稳定性的因素。方法探讨改善盐碱土团聚体结构的方法与策略及非盐碱土团聚体研究对盐碱土的启示。结果综合分析发现，盐碱环境破坏土壤结构，降低微生物多样性和活性，导致大团聚体数量减少，微团聚体比例上升，团聚体稳定性较差。非盐碱土大团聚体和微团聚体数量均较高，且分布层次分明，

Dual‐Layer Solid Electrolyte Interphase Enables Effective Suppression of Lithium Dendrites
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The heterogeneous solid electrolyte interphase (SEI) at the Li metal anode often leads to slow and uneven Li+ flux, causing severe Li dendrite growth. Herein, we combine X‐ray photoelectron spectroscopy and cryogenic transmission electron microscopy to demonstrate that a dual‐layer SEI, consisting of an inorganic inner layer and an organic ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Infected bone defects represent a dual therapeutic challenge demanding concurrent infection inhibition and osteogenesis promotion. Systemic antibiotic administration is taken as a classical treatment protocol but often yields inadequate local antibiotic concentrations and delayed bone repair.
