I guess it’s aimed at people what want to roam. & if you need or want Amazon prime then it’s price - £9 isn’t it. Probably 9 months or so, just found the reference on the o2 website. The stated 2Mbps ...

本研究揭示了活性氧物种(ROS)在美洲黑杨木质部发育中的关键作用。研究人员通过对比分析速生型(Wimco-109)和慢生型(Wimco-83)克隆株系发现，超氧阴离子(O2??)促进生长而H2O2导致木质化增强。研究证实NADPH氧化酶(NOX)活性差异调控ROS平衡，为造纸工业选育低木质素材料 ...

为解决电化学发光(ECL)传感中H2O2与溶解氧(O2)的竞争反应难题，研究人员开发了氮掺杂分级多孔碳负载单原子钴位点(Co?NC SAs)作为共反应加速剂。该材料选择性激活H2O2产生活性氧，显著增强鲁米诺ECL信号，并构建三通道传感器阵列实现五种塑化剂的高灵敏度检测 ...

光合成过氧化氢（H2O2）是太阳能的收集和转化的一种有效策略，但光合成H2O2的高效过程是由光生成的电子-空穴对重组导致的H2O2产率降低所驱动的，特别是在没有牺牲剂的情况下。基于此，厦门大学黄小青教授和韩佳甲助理教授、广东工业大学徐勇教授等人报道 ...
