基于向大一学生开设的“电解-量气法测定阿伏加德罗常数”实验，设计了Cu₂O的电化学合成及量气法测定阿伏加德罗常数一体化实验，该实验巧妙地融合了元素化学实验中有关Cu₂O的制备及性质实验内容。一次电解完成两个实验，节约电能，节省时间。Cu₂O的电化学合成及量气法测定阿伏加德罗常数一体化实验可作为一个微实验灵活穿插于大学基础化学实验教学中，对于培养大一学生的全方位思考的意识和多角度分析问题的能力以及经济、环保的理念有重要意义。

A series of novel titanium-oxo-clusters (TOCs, including Zn-Ti₁₁ and Cd-Ti₁₁) was designed for supercapacitors, expanding the potential application of TOCs. These materials demonstrate the benefits of titanium-based materials through their excellent pseudocapacitive energy storage capabilities. The prepared supercapacitor exhibited impressive performance, with a maximum power density of 9.5 W·kg^-1 and an energy density of 463 Wh·kg^-1.
