At the 19th Fluorine Chemistry Seminar held at Honokuni Toyohashi Arts Theatre PLAT, Chikamatsu gave an invited lecture. At the 48th Fluorine Chemistry Discussion Meeting, D1 Kamigaito delivered an oral presentation, while M2 Nakano, M2 Hagiwara, and M1 Tsukiji presented posters.

The paper on the fabrication of lead oxyfluoride epitaxial thin films has been published in J. Mater. Chem. C. This work is the result of a collaborative research effort with Hokkaido University. “Fluoride-target-assisted growth of Pb2OF2 oxyfluoride films with anion ordering and high dielectric constant”

Chikamatsu gave an invited talk titled “Topochemical fluorination of barium-substituted bismuth ferrate thin films” at The 20th Industry-Academia Collaboration Subcommittee of the Fluorine Chemistry Society of Japan held at Waim Ochanomizu in Tokyo.

D1 Kamigaito gave presentations at both the 2025 Annual Meeting of the Japan Society of Vacuum and Surface Science and its Young Researchers’ Session, held respectively at the Tsukuba International Congress Center and the University of Tsukuba.

Nana Suzuki, a fourth-year student in the Department of Chemistry, has been assigned as our member for the second half of FY2025. I look forward to working with her.

D1 Kamigaito gave oral presentations and M2 Nakano, M2 Hagiwara, and M1 Tsuiji gave poster presentations at the 86th JSAP Autumn Meeting 2025 at Meijo University Tempaku Campus.

The paper on the crystal structure and the fluoride-ion conductivity of cerium fluoride films has been published in Chem. Commun.. It is the result of joint research with Central Research Institute of Electric Power Industry, Shibaura Institute of Technology, NIMS, Hokkaido University, and Tokyo Metropolitan University. “Crystal structure and fluoride-ion conductivity of strontium cerium fluoride epitaxial films prepared by topochemical fluorination”

The paper on the ferroelectric and magnetic properties of bismuth iron oxide thin films has been published in J. Appl. Phys.. It is the result of joint research with Science Tokyo, Nihon University, Tohoku University, Hokkaido University, and Tokyo Metropolitan University. “Ferroelectricity and magnetic order at room temperature and electronic states of bismuth iron oxyfluoride thin films”

D1 Kamigaito received the Outstanding Student Poster Award at the Japan Society of Vacuum and Surface Science Kanto Chapter 10th Anniversary Symposium. Many congratulations!
