ABSTRACT The development of efficient and stable bifunctional electrocatalysts is a key challenge for the industrialization of hydrogen production by water electrolysis. In this work, Co‐doped NiS/Ni3S2 heterostructured nanowire arrays (Co–NiS/Ni3S2 NA) were successfully constructed by precisely modulating the phase‐selective behavior of nickel ...

ABSTRACT This study developed a FeSiAl@LMPGP composite material to address the demand for low‐frequency electromagnetic absorption. Through controllable heat treatment, FeSiAl particles and PbO nanoparticles self‐assembled into a high‐density Mott–Schottky heterointerface structure, which exhibited a significant built‐in electric field (BIEF) effect ...

近年来,陆续发现运行过程中GIS铝合金壳体发生比较严重的腐蚀现象,笔者针对两起典型GIS不同部位铝合金外壳腐蚀事件开展研究分析,认为母线铝壳体上形成的环流和腐蚀部位积水即感应电位是诱导形成电化学腐蚀的主要原因,腐蚀缺陷处的环流电流密度决定腐蚀速率和腐蚀程度,通过阐述铝壳体电化学腐蚀产生的条件和机理,证明运行过程中的GIS铝合金壳体在一定条件下会发生交流腐蚀,并依此研探提出防范措施。
