Flexible, Robust Transparent Conductive Films With Excellent Electromagnetic Shielding Properties
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Transparent conductive films (TCFs) are indispensable components for next‐generation wearable electronics, intelligent robots, and electromagnetic interference (EMI) shielding devices. However, the fabrication of conventional random metallic mesh suffers from an inherent trade‐off between “randomness and controllability”.

, 2017 提出一种针对复杂对象参数辨识问题的复合评价策略，通过分层设计优化指标评价函数，降低了迭代搜索计算对分辨局部极小值与全局最优值的需求，在少量增加计算消耗的条件下，显著提高辨识精度。以搭载多关节机械臂的空间机器人为复杂对象代表，配合一种改进型粒子群算法，在无须线动量测量信息和仅使用历史数据的条件下，对机器人抓取的目标的惯性参数进行参数辨识。115组辨识仿真算例的统计结果表明，使用该复合评价策略，基本不增加计算消耗，而辨识精度得到大幅提升。定性地分析认为群体智能算法与该策略配合更易发挥效果 ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The development of high‐performance, self‐powered ultraviolet photodetectors (UVPDs) is crucial for the practical application of low‐power‐consumption optoelectronic devices. However, achieving both broad‐spectrum detection and high sensitivity remains a challenge.

Gaoya dianqi, 2009 为了研究特高压复合绝缘子在长时间电场作用下的电场分布特性,笔者对特高压复合绝缘子进行有限元建模,并计算沿芯棒的电位分布。以完整细剖分模型的计算结果作为基准,将简化模型的结果与其对比来验证简化模型的有效性。通过比较证明了简化模型可以代替完整模型进行复合绝缘子电位分布的分析且能够在很大程度上减小计算规模,对特高压复合绝缘子的建模分析具有重要参考意义。

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Bio‐inspired artificial vision systems have made significant progress, but most focus on photo‐receptors, neglecting the hardware implementation of the efficient downstream neural circuits for complex computations like motion detection. To overcome this bottleneck, we demonstrate a neuromorphic vision system that mimics Drosophila's motion ...
