Æ E Æ Å – Reshaping the Role of Træna Fishermen

, 2022
This diploma project aims to strengthen the viability of Træna’s community by proposing an ocean research facility in the archipelago, enabling the next generation of local fishermen to collect oceanographic data while working at sea. The idea of the fisherman as oceanographer is inextricably linked to the architectural program on the island of ...

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 ...

小叶女贞叶片脲酶抑制物质的提取及抑制作用研究

四川大学学报. 自然科学版, 2010
从小叶女贞叶片中提取分离了具有抑制脲酶作用的活性成分并对其抑制作用进行研究.结果显示该活性物质主要成分为多糖和酚类物质,对脲酶有较强的抑制作用,随着脲酶抑制物质浓度增加,抑制作用增强.加入β-巯基乙醇(2-Me)后,脲酶的活性恢复,说明该脲酶抑制物质是通过与脲酶的-SH发生作用而导致脲酶的活性降低.

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 ...

硝化抑制剂对硝化菌群的影响及作用机制

Gongye shui chuli
通过序批式试验比较了不同投加量的生物硝化抑制剂〔对羟基苯丙酸甲酯（MHPP）、丁香酸（SA）〕与化学硝化抑制剂〔二氰二胺（DCD）、3，4-二甲基-1H-吡唑（DMPP）〕对硝化菌群的影响。结果表明，这4种硝化抑制剂在最适浓度下，显著抑制了亚硝酸盐氧化菌（NOB）的处理效能，从而降低了亚硝态氮转化率，抑制率达71.31%~87.38%。DCD、DMPP对氨氮转化率产生了一定的抑制作用，而MHPP、SA并未显著影响氨氧化菌（AOB）对NH4+-N的转化。亚硝化过程的主要功能菌AOB ...

In Situ Formation of L12‐Al3Ti Precipitates Enabling High Strength and Toughness in Oscillating Laser‐Welded Aluminum Alloy

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT A synergistic strategy combining a Ti interlayer and circular beam oscillation was proposed to improve the laser weldability of 6082‐T6 aluminum alloy. The Ti interlayer suppressed porosity, eliminated columnar grains, and significantly reduced grain size by 67.7% at the weld center. Mechanistically, fine L12‐Al3Ti precipitates clearly showing

High‐Entropy Engineering Enables Highly Exposed Mn3+ Active Sites and Stable Mn–O Coordination in α‐MnO2 for Efficient Bifunctional Oxygen Electrocatalysis

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Non‐noble metal oxygen electrocatalysts are essential for low‐cost rechargeable metal‐air batteries and fuel cells, determining their energy conversion efficiency. However, such electrocatalysts are limited by inadequate bifunctional activity and stability toward the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER).
