用原子力显微镜研究了超氧化钠（NaO2）在水中的沉积和溶解过程。矩形棱柱组成的8个较小的子结构生长从NaO2血小板，放电时，在0.5 M NaClO4，二甘醇二甲醚高度有序的热解石墨。在氧化过程中，8个亚结构是保守的。200 nm直径的环状结构的Na2CO3保持在氧化结束。
The deposition and dissolution of sodium superoxide (NaO2) was investigated by atomic force microscopy. Rectangular prisms consisting of 8 smaller sub-structures grew from NaO2 platelets, when discharged in 0.5 M NaClO4, diethylene glycol dimethyl ether on highly ordered pyrolytic graphite. During oxidation the 8 sub-structures are conserved. Ring-like structures of Na2CO3 of 200 nm diameter remain at the end of oxidation.
