Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The commercialization of lithium–sulfur batteries (Li–S batteries) has been hindered by the shuttle effect of lithium polysulfides (LiPSs) and sluggish redox kinetics. In this study, we constructed a three‐dimensional hollow conductive network host material for sulfur with synergistic enhancement effects.

Jianzhu Gangjiegou Jinzhan, 2018 提出一种基于损伤可控的梁柱节点(Web-Connected and Prestressed节点,简称WCP节点)。通过在梁端腹板设置连接钢板、摩擦耗能螺栓以及预应力筋,将梁柱连接在一起。为了研究该类节点的滞回性能、自复位能力和损伤特征,设计、制作并完成了4个足尺节点试件的低周往复试验,分别考虑了预应力筋的初始张拉力、高强度螺栓的预紧力以及拼接板的表面处理方式对节点性能的影响。试验结果表明:该类节点的破坏主要集中在拼接部分;节点通过螺栓的滑移变形提供了较好的耗能能力;预应力筋能够增强节点的刚度 ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The electrocatalytic co‐reduction of CO2 and nitrate (NO3− ${\text{NO}}_{3}^{-}$) to synthesize urea presents a sustainable alternative to traditional industrial processes, yet its efficiency is fundamentally limited by the kinetically mismatched activation and coupling of CO2 and NO3− ${\text{NO}}_{3}^{-}$.

Jianzhu Gangjiegou Jinzhan, 2010 设计钢管混凝土梁柱长圆孔变型性高强螺栓节点,上下节点板通过高强螺栓拼接连接钢管混凝土柱与钢筋混凝土梁,并引入长圆形螺栓孔以提高节点的延性变形性能。本文通过两个长圆孔变型性高强螺栓节点试件及两个传统焊接节点试件的低周反复加载试验,对不同连接方式节点在地震作用下的承载力、延性变形能力、耗能能力、滞回性能进行研究与对比。试验结果表明,螺栓节点满足节点承载能力,同时其延性性能好于传统焊接节点,节点的延性变形能力通过螺栓在长圆孔中的滑移有明显提高。与焊接节点相比较,最终两个长圆孔变型性螺栓节点发生延性破坏 ...

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”.

Guangtongxin yanjiu, 2017 在传统的Zigbee网络中,每层节点数据转发频率不均匀且通过泛洪路由请求报文来实现路径选择,会导致网络中节点能耗不均匀,网络过早出现分割死亡。针对传统路由算法在节点能量保护和延长网络生命周期方面的不足,提出了一种基于节点能量均衡机制的Zigbee路由算法IZRA-AODVjr,改进算法根据动态建立的全局节点能量度量标准对节点能量状态进行划分,通过控制中间低能量节点对路由请求报文数据分组转发,均衡网络各节点能量水平。仿真结果表明,改进算法有效地降低了网络整体能耗,提高了节点生存率。

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Infected bone defects represent a dual therapeutic challenge demanding concurrent infection inhibition and osteogenesis promotion. Systemic antibiotic administration is taken as a classical treatment protocol but often yields inadequate local antibiotic concentrations and delayed bone repair.
