Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The sluggish kinetics of the oxygen reduction reaction (ORR) necessitate developing oxygen electrodes with enhanced electrocatalytic activity for practical zinc–air battery applications. In this study, an iron‐doped copper sulfide electrocatalyst (CuFeNS‐PNC) anchored on metal–organic framework‐derived carbon substrates was designed, featuring

Whose Voices Are Heard? Parliamentary Committee Witnesses as Gendered Representatives
Politics &Policy, Volume 54, Issue 1, February 2026.ABSTRACT Are women sources of expertise for parliamentary policy discussions? In most parliaments, committees are the only venue where citizens can speak directly to the legislature; we argue that the proportion of women witnesses has implications for gender equality in policymaking. We present an original dataset of over 52,000 parliamentary committee

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 ...

Jianzhu Gangjiegou Jinzhan, 2010 为了更深入了解金属蒙皮支撑连续檩条在整体蒙皮结构中所起的作用,为今后我国对连续檩条以及蒙皮结构的设计、计算提供依据,通过足尺模型试验和有限元模型的分析,研究了蒙皮支撑冷弯薄壁连续型钢檩条模拟风吸力作用的承载力。利用有限元程序ANSYS建立了带有非线性弹簧单元模拟自攻螺钉这一符合实际连接状况的有限元模型,与足尺试验模型的失稳模式、荷载-位移曲线、连接强度以及连接刚度的规律等相对比,验证了有限元模型的合理性、有效性及适用性。

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 ...

齿轮可靠度计算的概率有限元法（第Ⅱ部分:齿面接触疲劳强度的计算）
Jixie chuandong, 1993 本文将概率有限元法用于齿轮接触疲劳强度可靠度的计算。以功率、转速和疲劳极限为随机变量,在求解接触问题的有限元—线性规划法基础上,建立了相应的概率有限元基本方程及求解方法。该方法不仅可用于齿轮接触疲劳的可靠度计算,也可用于其他弹性体接触问题的可靠度计算。
