Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT This study elucidates the oxidation mechanisms governing Y/Hf‐doped AlCoCrFeNiTi high‐entropy alloys (HEAs) and reveals the pivotal role of fabrication processes in dictating high‐temperature oxidation behavior. We demonstrate that casting and spark plasma sintering (SPS) promote Y/Hf segregation, resulting in heterogeneous oxide formation and

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Tungsten is inherently brittle and particularly prone to thermal stress concentration and crack formation during additive manufacturing processes such as laser cladding, which severely limits its engineering applications as a coating material. To address this issue, this study proposes an in situ toughening strategy involving the introduction ...

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 ...

Shiyou jixie, 2012 为了给采气管柱疲劳寿命分析和完整性分析提供依据，考虑管柱自重及内、外压沿深度的线性变化，用有限元软件分析振动采气管柱的应力强度。将采气管柱看作是内空的细长杆，用有限元法对管柱进行离散化处理，再用拉格朗日方程得到采气管柱动力学微分方程。采用二维轴对称模型进行建模，采用4节点平面单元Plane42进行分析。分析结果表明，采用ANSYS中轴对称单元Plane42建立采气管柱有限元模型，进行振动采气管柱的应力强度分析是一种有效的方法；井口管柱应力最大，是应力危险点；振动载荷作用下 ...

Using online reports of seahorse seizures to track their illegal trade
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Illegal wildlife trade (IWT) is a persistent and extensive threat to global biodiversity. Hundreds of marine fish species are subject to regulation under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), but it is unclear how much protection species gain from CITES because information on marine fish ...
