permeation

To address this, despite the name, metal-air batteries typically require additional equipment such as an oxygen permeation membrane to either purify oxygen or selectively use atmospheric oxygen.

The permeation of air into the soil accelerates the release of not only carbon dioxide from organic matter but also other greenhouse gases like nitrous oxide.

"This work exemplifies that we need to be more open-minded about what different aquaporins may permeate, besides water," said the paper's co-author, Professor Steve Tyerman, who previously revealed ion permeation in plant aquaporins.

"We call this a 'forward problem,' meaning you have a material and a mixture that goes in -- what comes out? That's a prediction problem. What we want to do eventually is to design new polymers that achieve a certain target permeation performance."
