Carbon‐Insertion‐Engineered WS2 Hierarchical Heterostructure Enabling Superior Sodium‐Ion Storage
Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Tungsten disulfide (WS2) is considered a promising anode material for sodium‐ion batteries (SIBs). However, its practical application is hindered by poor electrical conductivity, large volume changes during cycling, and sluggish ion diffusion kinetics, which lead to unsatisfactory electrochemical performance.

Dianci bileiqi, 2023 利用三维雷暴云动力—电耦合数值模式，通过对青海东北部地区2011年7月29日一次雷暴发展过程进行研究模拟，分析了青海东北部地区雷暴的电荷结构演变特征并从微物理方面讨论了其过程主要形成原因。结果表明，对流过程中霰粒子比含水量分布广，雹粒子比较少，以液态降水为主。青海地区雷暴以三极性结构为主，在上升气流比较弱时电荷结构呈现出下正中负的电荷结构，结构整体电荷密度分布较低，底部正电荷区与负电荷区深厚，霰粒子在下荷正电，冰晶在上荷正电。随着上升气流增大 ...

International Journal of Applied Linguistics, Volume 36, Issue 1, Page 522-539, February 2026.ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

Experimental methods for wind tunnel studies of seed dispersal by wind
Applications in Plant Sciences, Volume 14, Issue 1, January-February 2026.Abstract The complexity and variability of natural environments make quantitative studies of seed wind dispersal challenging. Wind tunnel experiments offer a controlled alternative to investigate the mechanisms of seed wind dispersal. This review focuses on wind tunnels and the associated technologies used for studying seed wind dispersal, including ...

太子河源头水源涵养林不同植被类型矿质态氮流失特征及其对环境因子的响应
Shuitu Baochi Xuebao, 2017 以太子河源头水源涵养林为研究对象，分析不同植被类型地表径流和壤中流的氮流失特征，运用冗余分析和偏冗余分析对氮流失特征与环境因子之间的关系进行分析，并对其主要影响因子进行定量分解，探寻太子河源头水源涵养林氮流失特征的关键影响因子。结果表明：不同植被类型地表径流和壤中流硝态氮是氮流失的主要形态，地表径流硝态氮的浓度是铵态氮浓度的1.5倍，壤中流硝态氮的浓度是铵态氮浓度的20.5倍。无论是地表径流还是壤中流铵态氮和硝态氮流失浓度的大小顺序均为人工林>杂木林>次生林。受径流量和壤中流量的影响 ...

Gallium‐Doped α‐MnO2 Cathode for High‐Performance Aqueous Zinc‐Ion Batteries
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Rechargeable aqueous zinc‐ion batteries (ZIBs) have received significant attention because of their high safety and low cost. MnO2 as a cathode material hampers the application of ZIBs due to its structural instability and dissolution during the operation of the battery.
