Gate-Opening of Soft material Mouth
I was invited as a plenary speaker in the 2019 International Conference on Nanospace Materials (ICNM2019) at The University of Queensland in Australia. When I was walking around the campus of this university, a bird on the shore of a pond was trying to catch and swallow a large fish. I was impressed by the fact that this was a macroscopic version of my research in the chemistry of soft porous materials (called flexible PCPs or MOFs), which have gate-opening capabilities and can take in a variety of gases. "Hey, good luck swallowing it!"
