Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these “bubbly” concoctions that will have major impact on the manufacturer of the world’s thinnest, flattest, and one most useful materials — graphene.

As graphene’s popularity grows as an advanced “wonder” material, the speed and quality at which it can be manufactured will be paramount. With that in mind, the group of SungWoo Nam, assistant professor of mechanical science and engineering at Illinois, has developed a cleaner and more environmentally friendly method to isolate graphene using carbon dioxide (CO2) in the form of carbonic acid as the electrolyte solution. The findings are published in the most recent Journal of Materials Chemistry C.

Nam, an expert in the area of 2D materials, is especially interested in graphene for its use in or flexible devices — for instance, a wearable patch that, when placed directly on skin, is so thin and transparent, it isn’t noticeable. Nam currently has projects with industry for making wearable graphene sensors.
