Researchers employ a novel electrochemical process to make carbon nanotubes from ambient carbon dioxide and use them to boost battery performance. by Mike Orcutt March 7, 2016 Sponsored by There is little economic incentive to capture carbon dioxide from power-plant exhaust or suck it directly from the air, but researchers from George Washington University and Vanderbilt University have hit on a possible motivation: using the gas to make materials for high-performance batteries. Not only is…
