We participated in the joint research meeting held at Yokohama National University with the Ashida Laboratory of Osaka University, the Iida Laboratory of Osaka Metropolitan University, the Kusabe Laboratory of the University of Hyogo, and the Bamba Laboratory of our university. Our fourth-year undergraduate students—Mr. Yui, Mr. Matsumoto, Mr. Shimizu, Ms. Asari, and Mr. Ehara—gave presentations at the meeting. We also had the opportunity to show several laboratories, including our own, to the visiting participants.
