Prof. Matsumoto has visited Prof. Terasaki (Department of Chemistry, Graduate School of Science, Kyushu University) on June 30. I excitedly enjoyed the laboratory tours of Terasaki Laboratory and Onda Laboratory. Surprisingly on that day, I was so happy to have an opportunity to participate in the special lecture by Prof. Tatsuya Tsukuda (Department of Chemistry, Graduate School of Science, The University of Tokyo).
