Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Efficient hole injection at metal‐semiconductor interfaces remains a central challenge for high‐performance p‐type transistors based on two‐dimensional (2D) semiconductors. Although substantial efforts have been devoted to reducing Schottky barrier height through contact engineering, the barrier width is rarely addressed, thereby limiting ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Additive manufacturing of zinc‐magnesium (Zn‐Mg) alloys via laser powder bed fusion (LPBF) has gained significant recognition as a promising candidate for bone repair. However, the presence of coarse yet brittle eutectic phases in the fabricated Zn‐Mg alloys tends to induce premature stress concentration and resultant fracture during ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Currently, the photocatalytic performance of ZnO has been severely limited by its weak light response ability and sluggish charge carrier dynamics, which considerably hinder its extensive application in photocatalytic fields. Herein, through anchoring the synthesized K6PMo11FeO40·nH2O (PMo11Fe) onto ZnO nanosheets, a novel S‐scheme ...

Gongye shui chuli, 2021 针对CASS污水处理工艺中提升泵组的调度控制问题，根据不同场合设计了三种协同控制方法。综合考虑被控对象和执行器的工况，第三种控制方法将调度问题分解为泵的投入优先级问题和投入数量问题。结合泵的电压误差、累计以及连续工作时间等状态信息，引入故障评价指标以确定泵的优先级；根据反应池液位划分等级，确定泵的投入数量并设计评价指标。经实验表明，控制方案能有效解决提升泵组调度问题，延长设备寿命，降低故障率。
