Rational Design of Bimetallic MOF‐Derived Cu/Co@N‐C Nanocubes for Ultrasensitive Electrochemical Nitrite Detection

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT A facile coprecipitation‐pyrolysis strategy was employed to fabricate Cu/Co nanoparticles (NPs) embedded in nitrogen‐doped carbon matrices (Cu/Co@N‐C) through the carbonization of CuCo‐MOF precursors. Moreover, monometallic counterparts of Cu@N‐C and Co@N‐C were also prepared via carbonization of bimetallic CuZn‐MOF and CoZn‐MOF, respectively.

Abnormal Phase Transition Mechanism in the CoCrAlY Bond Coat Revealed by In Situ and Ex Situ Experiments

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT In Co‐based alloys, the γ phase is normally stable at high temperatures and the ε phase at low temperatures, and there is a martensitic transition on cooling to ∼417°C. In the γ/β dual‐phase CoCrAlY bond coat of turbine blade thermal barrier coating systems, we observed the opposite: γ remained stable at room temperature, yet it underwent a γ →

Dual‐Site Electronic Modulation in Mn/Fe‐Doped Ni0.85Se for High‐Efficiency Urea Oxidation at Industrial Current Density

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Rationally designing an electrocatalyst to achieve stable and efficient urea oxidation reaction (UOR) is crucial but still challenging, especially for ampere‐level application. Herein, Mn and Fe dual‐doped Ni0.85Se (Mn/Fe–Ni0.85Se) catalyst is synthesized via a facile and scalable electrodeposition and followed by selenization.

Copper Slag‐Derived Cu3Fe17@C Alloy Enabling Efficient Peroxymonosulfate Activation for Levofloxacin Degradation via Cu‐Mediated Electron Transfer With Suppressed Metal Leaching

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Although alloy‐based materials present potential for peroxymonosulfate (PMS) activation, metal ion leaching remains severely restricted during the pollution degradation process. Herein, the porous carbon‐supported Fe–Cu alloy derived from industrial copper slag was prepared to remove the organic pollutants from wastewater while inhibiting the ...

特高压直流线路复合绝缘子空气中冲击击穿试验仿真研究

Gaoya dianqi, 2023
空气中冲击击穿试验是复合绝缘子设计试验和抽样试验的重要试验项目，也是检验复合绝缘子产品质量的重要手段。空气中冲击击穿试验采用幅值法时，复合绝缘子电位和电场分布受到加压距离、接线方式等影响，不同试验条件下的试验考核一致性与有效性还需要进一步研究。文中建立了某型特高压直流复合绝缘子有限元模型，分别仿真了复合绝缘子上、中、下段进行不同电极距离空气中冲击击穿试验时的电位、电场分布。通过分析了芯棒、护套内部和护套表面电位、电场分布规律，发现复合绝缘子试验段上下两端最大场强会随电极轴向距离和击穿电压的增大而增大 ...

Ophthalmic artery Doppler as potential surrogate marker of angiogenic imbalance in near‐term pregnancy

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 2, Page 211-219, August 2026.
ABSTRACT Objectives First, to evaluate whether the ratio of soluble fms‐like tyrosine kinase‐1 to placental growth factor (sFlt‐1/PlGF) is associated with hemodynamic changes in ophthalmic artery (OA) Doppler in near‐term pregnancy. Second, to assess the performance of OA Doppler to rule in and rule out angiogenic factor imbalance.
