The first thing that came to mind, and what would be an amazing twist of irony, is if graphene could be used to filter CO2 from stack emissions.

A-ha!!! That didn't take long. Found it within my edit time.

I found a good link on physorg.com : http://phys.org/news/2012-06-nanoporous-graphene-outperform-commercial-desalination.html

ronwagn Nice link and thanks. It would be expected that if a material is able to work faster and at less pressure and is stronger, it would be more effective. Graphene also shows good promise for future applications. There are also other developments in separation of ions and one that still intrigues me is the exclusion zone created using nafion tubes. I submitted this link on another thread and thought it would also be appropriate here. You may want to fast forward to about the 50 minute mark of this link. The thing to understand is that the exclusion zone is created by the nafion tube and exists even with flow. I tried to find some updates on the application and was directed here. But there are lots of links to be found to nafion tube, exclusion zone, and water treatment.
