Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Heteroatom coordination regulation is an effective strategy to enhance Fenton‐like catalysis of single atom catalysts, yet its impact on the local microenvironment of active sites still requires in‐depth investigation. Herein, Cl2–Fe–NC catalysts with axial Cl coordination are prepared.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Germanium is a critical dispersed metal, yet sustainable recovery from dilute solutions is limited by sorbents that are difficult to regenerate and operate in continuous mode. Here, we fabricate a regenerable 3D‐printed hydrogel monolith (3D‐ATO‐GS) by integrating hydroxyl‐rich amorphous TiO2 nanoparticles into an alginate/gelatin scaffold ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Engineering of the catalyst interface and modulation of transition–metal d–band play critical roles in the electrocatalytic hydrogen evolution reaction (HER). Herein, a synthetic strategy is developed to fabricate nitrogen‐doped carbon nanotubes (N–CNTs)–supported Ni3Se4–CeO2 heterojunction catalysts through a facile chemical vapor deposition (

Dianci bileiqi, 2022 连续雷击是一个近年引起关注的变电站防雷新热点，位于变电站线路开关断口外线路侧的无间隙金属氧化物避雷器(包括高抗中性点避雷器)成为连续雷击侵入波防护的薄弱环节。笔者以某变电站高抗中性点避雷器在连续雷击下热崩溃故障作为案例，建立模型对避雷器吸收能量进行仿真分析，结果表明：在连续雷击工况下，避雷器电阻片累计吸收能量而发热易造成电阻片劣化；在电阻片劣化基础上，如果避雷器承受正常系统电压或者承受持续振荡电压，续流增大，最终发展到热崩溃的风险很高；在连续雷击风险较高的地区，应提高避雷器对连续雷击的能量吸收能力 ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The urgent environmental crisis caused by polyethylene terephthalate (PET) waste necessitates efficient upcycling strategies. Herein, we establish a novel pathway to transform waste PET plastic into a high‐performance catalytic material for mediating the oxygen evolution reaction (OER). Through a one‐step hydrothermal process, waste PET serves

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Moisture‐enabled electricity generation technology offers a new paradigm for sustainable energy harvesting, but its practical applications are still limited by issues such as low output power and insufficient long‐term stability. In this paper, an asymmetric sandwich‐structured hydrogel moist–electric generator (SSHMEG) with an ion ...

Shiyou jixie, 2015 准确地分析连续管流体特性对施工作业的成功有着重要意义。为此，以垂直井和水平井注入流体为研究对象，建立了流体特性参数计算模型，分析了连续管流体的特性参数。以Visual Studio 2013为开发平台，自主开发了连续管流体特性参数分析软件。通过软件计算分析，确定了连续管内和环空流体压力损失大小，流体流速和流态，任意位置压力大小，得出压力变化曲线和排量泵压流动特征曲线。研究结果为确定合理的泵压、排量和优选连续管提供了依据。

Two decades of changes in the global network of illegal wildlife trade
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Understanding how illegal wildlife trade (IWT) has changed over time is fundamental for biodiversity conservation; however, knowledge of the network remains limited. We used TRAFFIC's IWT dataset, legal trade data from the CITES legal wildlife trade database as a benchmark, and network analysis to identify changes in IWT from 2000 to 2022. The
