Process Synthesizes Carbon Nanotubes Using Carbon Dioxide

Carbon nanotubes are supermaterials that can be stronger than steel and more conductive than copper. The reason they're not in every application from batteries to tires is that these properties only show up in the tiniest nanotubes, which are extremely expensive. A new process was developed that can make these materials from carbon dioxide drawn from the air, in a way that is much less expensive than other methods. These materials could impact how emissions can be used in future technology.
