Colloid‐Mediated Surface Reconstruction Through High‐Valence Element Integration Enables Stabilized Oxygen Redox and Fast Interfacial Kinetics in Li‐Rich Cathodes

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Lithium‐rich manganese‐based cathodes (LRM) deliver high discharge capacities beyond 250 mAh g−1, but their practical deployment is restricted by irreversible oxygen redox, structural reconstruction, sluggish kinetics and unstable cathode‐electrolyte interfaces (CEI). Here, we develop a colloid‐assisted anchoring‐diffusion engineering strategy

Lignin‐Derived Carbon Quantum Dots as Hole‐Trapping Promoters in LCDs/Bi‐MOF/ZIS With S‐Scheme Heterojunction for Efficient Photocatalytic Hydrogen Peroxide Production in Pure Water

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Photocatalytic hydrogen peroxide (H2O2) production from water and oxygen driven by solar energy represents a highly promising green and sustainable strategy. Herein, lignin‐derived carbon quantum dots (LCDs) were strategically introduced at the heterojunction between a Bi‐based metal organic framework (Bi‐MOF) and ZnIn2S4 (ZIS).

Tuning Grain Boundary Carbides via Solute Rare‐Earth Elements to Prevent Intergranular Brittle Fracture

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Carbides strengthen the grain boundaries; nevertheless, excessive carbide precipitates embrittle the grain boundaries of high‐temperature alloys during prolonged service. Here, we provide direct evidence of solute rare‐earth atoms and demonstrate that they can trap vacancies and inhibit interstitial diffusion, restraining carbide precipitation

Bidirectional Interfacial Chemical Regulation Enables Durable Aqueous Zn‐I2 Batteries

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Aqueous Zn‐I2 batteries hold great promise for large‐scale energy storage, yet their practical deployment is hindered by coupled interfacial instabilities at both electrodes, where Zn‐anode parasitic reactions and cathodic polyiodide shuttle mutually aggravate each other.

Functionalized Silica‐Constructed Self‐Supporting Composite Separator for Lithium Metal Batteries

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Lithium metal batteries (LMBs) are considered highly promising next‐generation energy storage systems owing to their exceptionally high theoretical specific capacity and ultralow electrochemical potential. Nevertheless, the practical deployment of LMBs is still severely restricted by the uncontrollable formation and propagation of lithium ...

Lanthanide Nanoparticles With Dual Enzyme Mimetic Activities for Targeted Treatment of Gram‐Negative Bacterial Infections

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Gram‐negative (G−) bacterial infections, fueled by intrinsic antibiotic resistance stemming from their unique outer membrane architecture, pose a critical global clinical challenge. This study introduces a pioneering dual‐enzyme‐mimetic nanotherapy based on NaYbF4 nanoparticles (NaYbF4 NPs) that achieves synergistic antibacterial and anti ...

预览搜索中优先选择的非抑制加工机制

, 2006
视觉系统会优先选择与当前行为目标相关的刺激，忽略无关刺激。这种视觉优先选择（prioritizing selection）现象及其机制一直是视觉搜索研究所关注的焦点。本研究对预览搜索（preview search）中优先选择的解释机制进行了详尽的探讨，从基于旧干扰物位置的抑制和基于旧干扰物属性特征的抑制两方面系统检验了基于抑制的视觉标记的解释，并基于实验结果提出了预览搜索中优先选择的非抑制加工机制。 本研究分为三个部分，共9个实验：研究一考察预览搜索的优先选择是否是基于旧干扰物位置的抑制 ...

玉米巯基蛋白酶抑制剂的纯化及部分性质

四川大学学报. 自然科学版, 1998
从玉米种子纯化出两种巯基蛋白酶抑制剂（ＣＰＩ Ⅰ和ＣＰＩ Ⅱ），分子量分别为９５００和１３０００，它们都只抑制巯基蛋白酶的水解活性，而对丝氨酸蛋白酶则无抑制作用，属于巯基蛋白酶水解抑制剂，它们在ｐＨ３．０～１１．０或１００℃温度范围内保有１００％的抑制木瓜蛋白酶的抑制活性，表明在这些外界条件下其分子非常稳定．
