On 25th January 2018, Asst. Prof. Dr. Phimphaka Harding, head of the Functional Materials and Nanotechnology Center of Excellence (FuNTech), had a chance to talk to students from Nara Prefectural Seisho high school of Math and Science, Japan and Princess Chulabhorn’s College Nakhon Si Thammarat. We hope that our fun research will inspire the Japanese and Thai students to continue on study science in the future.
