Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Engineering of the catalyst interface and modulation of transition–metal d–band play critical roles in the electrocatalytic hydrogen evolution reaction (HER). Herein, a synthetic strategy is developed to fabricate nitrogen‐doped carbon nanotubes (N–CNTs)–supported Ni3Se4–CeO2 heterojunction catalysts through a facile chemical vapor deposition (

, 1998 1997年7月底，严克强副部长随同李岚清副总理赴西安参加“杨凌农业高新技术产业示范区”成立大会期间，就关于“节水灌溉研究开发中心”的建设问题，谈了以下几点意见。一、建设“节水中心”，关键要有一个正确的思路。如何搞节水灌溉？要根据实际情况，具体分析不同地区的灌溉特点，有针对性地研究节水灌溉的技术方法和设备。例如，在井灌区搞喷、滴灌，技术上是不成问题的，但如果是引用黄河或渭河水，泥沙的淤积和堵塞就是个大问题。因此 ...

Jianzhu Gangjiegou Jinzhan, 2022 在对方钢管柱-H形钢梁顶底T形钢单向螺栓连接节点进行了单调静力加载试验基础上，利用ABAQUS软件进行有限元分析，通过对比验证了有限元模拟结果的准确性。基于试验节点（BASE节点）模型，通过改进节点构造，建立5个系列的节点有限元模型，以模拟分析不同构造下的节点性能。研究结果表明，增加柱壁厚度能够明显提高节点的初始转动刚度和极限承载力，柱壁厚度超过14 mm时会发生单向螺栓的剪拉破坏，节点的变形性能下降；设置加劲肋能明显提高节点的极限承载力，但加劲肋厚度对节点性能影响不大 ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

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。
