This new approach allows for the utilization of non-PGMs such as iron, nickel, and cobalt as electrode catalysts while requiring no highly concentrated alkaline solutions [16], [17], [18], which increase the corrosion resistance of current collectors and bipolar plates and therefore enhance ...
观察类肝不及甘糖酯对体外培养的大鼠晶状体上细胞增殖的影响。方法将质量浓度为0.2,0.4,0.8mg/ml的类肝素和PGMS作用于培养细胞,72h后结晶紫染色比色测定,并对24h内的^3H-TdR捅入率进行测定。结论类肝素,甘糖酯对体外2的大鼠晶状体上皮细胞有明显抑制作用。关键...
? 2024 European Control AssociationThis paper proposes model-based and model-free policy gradient methods (PGMs) for designing dynamic output feedback controllers for discrete-time partially observable deterministic systems without noise. To fulfill this objective, we first show that any dynamic output ...
1.合成高性能析氢反应(HER)电催化剂的顺序还原策略 作者提出了一种合成高性能催化剂的顺序还原策略,先将铂族金属(PGMs)预埋在基体中,然后由于其还原电位低,优先发生氢还原反应,并固定在其表面(图1a)。通过这种策略合成的催化剂具有低含量的铂族金属,该铂族金属高度分散并牢固地锚定在大表面积和耐腐蚀的基底上。作...
Analysts have predicted that PGMs would recover quickly amid the metals' solid fundamentals, and with platinum's low price especially drawing investor interest. 年份: 2021 收藏 引用 批量引用 报错 分享 全部来源 求助全文 国家科技图书文献中心 (权威机构) ...
