Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The Schottky barrier height (SBH), which serves as a pivotal determinant of charge carrier injection efficiency in electronic devices, critically governs electrical behavior at metal/semiconductor interfaces. However, pronounced metal‐induced gap states at metal contact interfaces induce Fermi‐level pinning, which constrains the ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Two‐dimensional (2D) nonlayered niobium nitrides have attracted considerable interest for electrochemical energy storage. However, the synthesis of these materials is hampered by their nonlayered crystal structures, which are characterized by strong three‐dimensional chemical bonding.

Dianci bileiqi, 2018 在热力学模型基础上,考虑了空间电荷屏蔽作用的二次电晕起始过程,认为流注茎（电晕区与流注-先导转化区）温度达到1 500 K同时二次电晕起始即新生迎面先导起始。并且根据纹影仪对先导通道根部的观测结果,流注茎假设为类圆锥状。通过Comsol软件对地面高大建筑物尖端处上行正极性先导的始发过程进行了数值模拟研究,并分析了锥形流注茎和二次电晕起始过程对先导始发过程的影响。最终得到了锥形流注茎长度与流注茎半径的关系,证明了随着电流的注入,根部优先转化为先导;计算的建筑物尖端处在最大半径（R=0.24 mm ...

Study of NPZD Ecosystem Dynamical Model Application in Beibu Gulf [PDF]
, 2016 北部湾是我国重要的海湾和渔场，被誉为我国“最后的洁净”，近年来在我国沿海经济发展的成就和潜力倍受关注，然而工业化、城镇化进程的持续加快，也给北部湾的生态环境带来了巨大压力。鉴于此，研究北部湾生态系统的时空分布特征及其对动力环境变化的响应过程具有重要意义，可为我国北部湾生态环境保护建设、资源管理开发和经济发展策略制定等提供科学参考依据。 本文在已建立的“北部湾三维水动力—NPZD生态耦合模型”的基础上进行了进一步的拓展和应用研究，结合历年观测数据、卫星遥感数据和数值模型结果 ...

A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...

Huli yanjiu, 1997 通过对５０个一次性引流袋实际注水量与引流袋标量刻度的对照观察，发现一次性引流袋标量与实际注水量有差异。当注入３００ｍｌ以下水量时，引流袋内标量多数大于实际量，而注入３００ｍｌ以上水量时，引流袋标量明显少于实际量。提示：临床护士对于要求准确记录出入量的患者，测量引流量时一定要用量杯测量，以避免误差。
