Finally, 3D-printed graphene aerogels for water treatment

Graphene excels at removing contaminants from water, but it's not yet a commercially viable use of the wonder material. That could be changing. In a recent study, University at Buffalo engineers report a new process of 3D printing graphene aerogels that they say overcomes two key hurdles -- scalability and creating a version of the material that's stable enough for repeated use -- for water treatment.
