① [Dr. Aoyagi, Dr.Okubo, and Mr.Kawashima talk at ECS meeting on Li⁺@ C₆₀]
Shinobu Aoyagi associate professor of Nagoya City University, Takashi Okubo associate Professor of Osaka University, and Kawashima Yuki were invited to the "Electrochemical Society (ECS)" meeting held in Toronto, Canada from 12th to 16th May. They will present the results of studies using our Li⁺@ C₆₀.


・ Crystal Structure Analysis of Cationic Lithium Endohedral Fullerene Under Electric Field(Dr.Aoyagi)


・ Photoinduced Charge Separation in Supramolecules Between Li⁺@C₆₀ and Chlorins


・ Photoinduced Electron Transfer From Sc3n@C80 to Li⁺@C₆₀(Mr.Kawashima)
