In the first two weeks of June 2025, Chen went to east coast for two weeks. He attended DOE VTO Annual Merit Review at DC meeting to discuss the project on recyclable resin for continuous carbon fiber composite materials. Then he attend the Gordon Research Conference on polymer chemistry at South Hadley, Massachusetts. He also gave seminars at University of Delaware, Massachusetts Institute of Technology, and Formlabs Inc. It is so nice to reconnect old friends and make new friends! The east coast “tour” was fruitful and inspired new research directions and ideas!
