ナトリウム過剰酸化物の充放電過程における構造変化に着目し、試料が含む積層欠陥量を精密に計測した。得られた結果を受入研究者が俯瞰的に検証することで、層状化合物の充放電過程における構造変化がファンデルワールス力に依存するのに対し、ナトリウム過剰酸化物やリチウム過剰酸化物はクーロン力に依存しており、充電状態で構造が安定化されることを見出した（B. Mortemard de Boisse, et al., Nature Communications, in press, (2019)）。

In the process of acidizing, the process of acidizing is very important, and the material contains a precise calculation. The results are subject to the results obtained by the researchers. The results were analyzed by the researchers. The results show that the results are affected by the results obtained by the researchers. The results show that the results are affected by the results obtained by the researchers. The results show that the results are affected by the results of the study, the results show that the results are affected by the results obtained by the researchers, and the results show that the results are affected by the results obtained by the researchers, which are overlooked by the researchers.
