membranes for highly efficient gas separation

Stacked MXene nanosheets form uniform sub-nanometer channels that let hydrogen through 160 times faster than CO2, beating the best existing gas-separation membranes.

COF RIO-18/Polyurethane Mixed Matrix Membranes with Enhanced CO(2) and CO(2)/N(2) Selectivity

Adding tiny amounts of a CO2-attracting porous powder to polyurethane films more than doubled CO2 flow and boosted CO2-over-nitrogen selectivity by up to 454%.

Innovative bioreactor designs for enhancing electron transfer, mass transfer, and product yields in microbial electrosynthesis

Better-engineered reactor hardware — flow cells, gas-diffusion cathodes, packed-bed electrodes, built-in separation — is the main lever for making microbial electrosynthesis of fuels from CO2 practical.
