Gongye shui chuli, 2022 通过共价交联、原位沉积以及光致还原反应得到Ag@AgCl/GO/CA不溶性光催化颗粒材料，采用SEM、TEM、FT-IR、Raman和BET对该光催化材料的形貌、元素组成及比表面积进行表征。通过光电流及电化学阻抗分析（EIS）评价光催化材料的光电性能，利用ESR自由基检测和猝灭试验分析其光催化机理。结果表明，Ag@AgCl纳米颗粒呈团簇状分布在GO/CA的褶皱状结构上，且Ag和AgCl比例约为1∶1。因存在配位交联作用，Ag@AgCl/GO/CA光催化材料的含氧官能团明显减少，GO的两个特征峰变弱 ...

高土壤电阻率地区柔性石墨复合接地材料与圆钢接地材料的有效长度对比研究
Dianci bileiqi, 2018 改善杆塔接地能够有效的降低输电线路雷击跳闸率,对于高土壤电阻率地区的杆塔,减小冲击接地电阻是降低雷击跳闸率的关键,而减小接地体冲击接地电阻可以通过延长接地体长度来实现,但是当长度超过一定值时,延长将不再有效。因此研究接地体的有效长度、选取有效长度更长的接地材料,对降低接地电阻有着重要意义。首先分析了接地体有效长度的物理意义,然后运用CDEGS仿真软件计算工程中常用的镀锌钢和柔性石墨复合材料水平接地体的工频接地电阻与接地体长度、冲击接地电阻与接地体长度之间的关系 ...

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Internal oxidation has been identified as an effective method for enhancing the strength of AgMg alloys. However, the concurrent occurrence of embrittlement remains inadequately understood, thus limiting their broader application. This study investigates the oxidation behavior of AgMg alloys with Mg concentrations ranging from 1 at% to 7 at ...
