Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The central challenge in photocatalysis is to direct photogenerated electrons and holes toward the simultaneous and efficient production of hydrogen and value‐added chemicals. To address the pronounced charge recombination and sluggish surface kinetics of ZnIn2S4 nanoflowers, we construct a ternary photocatalyst synergistically decorated with ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Photocatalytic acetylene (C2H2) semihydrogenation is a green route for ethylene (C2H4) production, yet the activity–selectivity trade‐off caused by imbalanced adsorption/activation of reactants and products remains a core challenge. Herein, we realize precise regulation of Pd oxidation states (Pd0, Pdδ+, and Pd2+) on anatase TiO2 nanocubes via

TA10 Titanium Alloy in HCl Solution: W‐Influenced Corrosion and Passivation Film Evolution
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT This work investigated the evolution of passive films of Ti–0.3Mo–0.8Ni (TMN) in 5 mol L−1 HCl and studied the influence of W on the anti‐corrosion properties of TMN. The intermittent electrochemical impedance spectroscopy test results showed that when TMN entered 5 mol L−1 HCl solution, the stability of the passive film first became stronger ...

Entrapping the Hegemon: How Benjamin Netanyahu's Threat Rhetoric Drives US Military Escalation
Politics &Policy, Volume 54, Issue 5, October 2026.ABSTRACT How do materially weaker junior allies influence a hegemon's military posture? Existing theories rely on unobservable covert diplomacy, leaving alliance entrapment methodologically unresolved. This research note introduces a mixed‐methods framework, integrating computational text analysis, time‐series forecasting, and qualitative process ...

Jianzhu Gangjiegou Jinzhan, 2009 工字形和T形截面的变内力杆件在桁架中经常出现,如何确定其平面外的计算长度系数,现行规范中无明文规定。因此分析和研究变内力杆件的平面外计算长度系数,具有重要的工程意义。本文利用ANSYS对工字形和T形截面变内力杆件的计算长度系数进行了分析,研究表明:采用工字形和T形截面时变内力杆件的计算长度系数μy几乎相等,可以利用μy计算T形截面变内力杆件的μyz;根据计算长度系数μy随参数η和ξ的变化趋势,拟合得出简化计算公式,并提出了考虑扭转效应的μyz的计算公式。
