In Qijiang District, in southwest China's Chongqing Municipality, there is a home-like bookstore, established in 2003 by Li Ying and her husband, Zhang Yubo. Li and her family love to read. The couple has organized creative activities in the bookstore, such as giving lectures on traditional Chinese culture, hosting book-exchange markets, and designing picture books. Li's family was selected a National Most Beautiful Family in May. (Source: Women of China)

“I feel a little tired,” Zhang said. “The 100 fly is a much better event for me. Swimming on the third day I still feel sleepy and my body is tired, but it was a good result for me.”
“我觉得有点累，”张雨霏说，“100蝶对我来说好很多。第三个比赛日我仍然觉得困，身体也很疲惫，但对我来说是个不错的成绩。”

【美国田纳西大学F-Y Zhang等：催化剂利用率提高237倍！首次电化学生长超低负载铂纳米片超薄电极】美国田纳西大学的Feng-Yuan Zhang课题组采用无表面活性剂和无模板的快速室温电化学生长工艺，首次在薄的钛液/气扩散层(厚度：25微米，孔径：100微米，孔隙率：40%)上沉积了自下而上生长的超低负载和表面覆盖良好的Pt纳米片(Pt-NSs)，纳米片厚度仅为4 nm且均匀地垂直排布于基底表面。与传统的基于Pt纳米粒子催化剂和CCM设计相比，催化剂和电极制备过程大大简化。当与仅阳极Nafion 117 CCM相结合时，Pt-NS超薄电极在0.015 mgPt cm⁻²的超低负载量下，能够实现优于商用CCM的电解池性能，节省了99.5%的Pt催化剂，并提高了237倍以上的催化剂利用率。此外，与传统的厚GDEs(几百微米)相比，超薄电极仅约25μm，省了材料/重量/体积/成本，有利于未来紧凑型堆栈设计。 详情请点击https://t.cn/A6Wvdm4p免费获取全文。Nano-Micro Letters (2023)15: 144
