We designed a net made from microporous organic polymers (MOPs), which have a pore width of less than 2 nm – similar to the size of CO2 molecules – making them a good candidate for gas capture and sequestration by a simple physical sieving process.
This process provides a smaller energy penalty and associated cost than the current state-of-the-art gas uptake methods.
In our paper we demonstrate which types of MOPs are best at carrying out this “gas butterfly” capture.
From the art desk
When I was a child my family lived on the beach of the Yellow River. My childhood memories are full blue sky, green grass, thick, loose snow and cute animals… Now all of this has disappeared and instead there are tall buildings, large factories, and a chimney working around the clock. Last time I went back to my homeland I was wondering where the clean, well-lit place of my mind had gone.
I wanted the cover image to show the importance of working to improve our communal environment, for the future and for our offspring. We need to guide and educate our children to reverse the deterioration of the environment.
Several days after I was asked to design the cover image for Polymer Chemistry, I still hadn’t made any progress, so I asked my three-year-old niece:
"Where is the cleanest place on earth in your mind?"
She said, "The bear house at the zoo".
I was surprised and said, "Why do you think the bear house at the zoo is the cleanest place?"
She said, "Because the bear is white, if the playground is not clean, he will dirty his body…"
"Hahaha, good answer!"
That conversation inspired me to design the bear characters along with my coworkers Dr Qing Li and Professor Xiaoyun Li.
