Filling Uniformity of AgNPs in EMI Shielding Patch Regulated by Surface Morphology
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Silver nanoparticles (AgNPs) are extensively employed for electromagnetic interference (EMI) shielding owing to their remarkable conductivity, and are commonly incorporated into polymer matrices. Therefore, the uniformity of the AgNP distribution within the polymer matrix is a crucial factor that affects the EMI shielding performance.

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Thermodynamic prediction‐driven phase‐field kinetic simulation, with experimental verification, is utilized to explore the high‐performance cobalt–nickel based (CoNi‐based) superalloys. The roles of aluminum (Al) in microstructural evolution and precipitation kinetics of ordered L12‐γ′ strengthened Co–Ni–xAl superalloys are revealed. The alloy

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...

Integrative Conservation, Volume 4, Issue 4, Page 652-664, December 2025.We profiled nutritional and physiological markers in captive sifakas, endangered primates from Madagascar, managed in expansive, non‐native forest enclosures. Variation in many markers reflects freely foraged diets and the energy required to maintain homeostasis under more naturalistic conditions.

Gaoya dianqi, 2017 气体绝缘金属封闭开关（gas insulated switchgear,GIS）在电力系统中应用广泛,其内部触头过热会引发重大事故,因此研究其温度场分布特性具有重要意义。文中设计了252 kV GIS温升实验平台,通过实验获得了GIS母线导体、SF6气体和外壳部位的温度分布情况。针对上述实验平台建立了GIS三维物理模型和数学模型,基于有限元分析法对上述实验获得的GIS母线壳体温度场分布规律进行了仿真佐证。研究结果表明,在GIS壳体内部靠上区域,SF6气体温差较小,梯度不明显,而在GIS壳体内部下方区域 ...

Gaoya dianqi, 2021 分体自冷式变压器内部温度场的仿真分析多基于二维仿真,缺乏对油流流场影响的分析。文中建立110 kV水平分体式油浸自冷变压器的三维全尺寸模型,采用有限元分析方法仿真变压器内部温度场和流速场的分布,研究变压器本体与散热器间的水平布置距离对温度场和流速场的影响,分析变压器流场和温度场的耦合关系,并采用短路法温升试验验证仿真结果的准确性。结果表明,变压器内部热点出现在低压绕组B相两侧距绕组底部约0.68 H处,热点温度达369.7 K。随着变压器本体与散热器间的水平布置距离的增大 ...

Predictions of southern migration timing in coastal sharks under future ocean warming
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from

Gaoya dianqi, 2022 文中为了研究干式空心电抗器产生匝间绝缘破损的内在机理，构建了基于温度场的BKK—20000/63型电抗器三维仿真模型，并依据模型材料特性参数进行了仿真；得到了不同环境下温度场分布图，不同运行电压下各包封平均和最大温升特性曲线，以及不同温度场下各包封热应力分布特性；最后通过实物模型拉伸强度验证了仿真的有效性。通过仿真分析得出干式空心电抗器轴向温度场分布不均，且与运行电压有关，尤其是在环境温度较高或较低时，轴向温度场极不平衡产生的热应力是造成干式空心电抗器局部匝间绝缘破损的根本内在动力。
