“The hydrogel grabs the positive ions and prevents their diffusion,” he says ... Excellence for Electrochemical Transformation of Carbon Dioxide (GETCO2), a research consortium led by UQ.

In other membrane systems, slow diffusion of carbon dioxide across the solid membrane is the rate limiting step. “Because our hydrogel can be made by almost entirely of water, carbon dioxide ...

Diffusion happens naturally and so does not require energy. Substances like oxygen, carbon dioxide and glucose move in and out of cells by diffusion. If I spray a little perfume over here, ...

The conversion of carbon dioxide (CO2) into valuable chemical products via the electrochemical CO2 conversion reaction could ...

(Courtesy: Sabbie Miller) Replacing conventional building materials with alternatives that sequester carbon dioxide could allow the world to lock away up to half the CO 2 generated by humans each year ...

The amount of carbon dioxide that plants absorb and wipe from ... was a better understanding and representation of “mesophyll diffusion,” the process in which OCS and CO2 move from the leaf ...
