Chemists create 3-D printed #Graphene foam

Nanotechnologists from #RiceUniversity and #China’s Tianjin University have used 3-D laser printing to fabricate centimeter-sized objects of atomically thin #Graphene.

The new Rice process used a commercially available CO2 laser. When this laser was shone onto the sugar and #Nickel powder, the sugar was melted and the nickel acted as a catalyst. #Graphene formed as the mixture cooled after the laser had moved on to melt sugar in the next spot.
