二氧化钌作为一种很有前途的酸中析氧反应催化剂受到了广泛的关注。然而,由于RuO2被过度氧化为可溶的H2RuO5,导致其耐久性较差,阻碍了RuO2在质子交换膜水电解中的实际应用。在这里,我们报道了一种限制策略,通过富集高浓度的原位形成的H2RuO5物种 ...

研究团队利用谷氨酸盐类分子在水溶液中既可以通过自由基引发机制发生氧化聚合,也可以在施加外界条件下通过缩聚反应进行聚合的特性,实现了在正、负极表面同时构建以聚谷氨酸(PGA)为主要成分的EEI层,从而实现抑制活性物质溶解、副产物积累和锌枝晶生长等多重功 ...
在 CES 2025 大会的开头,不少厂家都拿出了亮眼的产品或规划,从个人日常用品,到跃进九天之上的航天火箭,层出不穷。 但要说起今天的主角,戴尔一定占据了一席之地。 与别家以发布各式各样的新产品来夺人眼球不同,戴尔的热度有点剑走偏锋——砍产品。
