This is an international symposium for design of advanced materials for membrane science and technology. Prof. Dun-Yen Kang and Prof. Li-Hsien Yeh, who have been awarded “The SCEJ Award for Outstanding Asian Researcher and Engineer 2020”, are invited to give a plenary lecture. Spirited and energetic researchers working on design of advanced materials for membrane science and technology are also invited to discuss widely fundamentals and applications of membrane science and technology. We hope this symposium will be fruitful and contribute to discuss the recent progress in design of advanced materials for membrane science and technology.
