Characteristics of groundwater circulation in typical karst trough areas：A case study of Longtan trough valley in Youyang, Chongqing [PDF]
Although the southwest karst valley region of China has an abundance of groundwater resources, little is known about the variations in the karst trough valley’s groundwater types and their cycle features. Using the Chongqing Youyang Longtan trough valley

Shuitu Baochi Xuebao, 2020 准确地预测农田地表径流是实现农业面源污染控制的基础，根据降雨和地表径流的运动特征，耦合Green-Ampt模型累积入渗量显函数、运动波模型和稳态的产沙模型，建立了降雨条件下的坡面产流产沙近似解析模型。该模型通过线性表示入渗率和水深之间的关系近似求解了运动波方程，通过设置30~90 mm/h的5种不同雨强的模拟降雨试验，推求模型参数并验证模型精度，并对模型参数进行敏感性分析。结果表明：（1）径流和泥沙的模型计算值与实测值吻合较好，且模型更适合于模拟60 mm/h雨强下的产流产沙过程，曼宁糙率系数均分布在0.

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 Low conductivity, slow ion‐diffusion, and limited reactive sites are common problems in electrocatalysts and electrode materials. In this study, a complex NiTe–CoTe heterojunction with abundant Te vacancies embedded in N, P, and F co‐doped hollow carbon nanorods (NiTe1−x–CoTe1−x/NPFC) was fabricated via a simple ionic liquid‐assisted ...
