Before revision: Various shapes can be drawn, which allowed the scientist duo essentially to laser-print an ultracapacitor on graphene using consumer-grade technology
After revision: .Another use is to prepare a PCB layout on an unburned LightScribe CD-R as there is enough contrast to form a weak shadow image on a photosensitive PCB with UV light.The ratio with a single pass is not that good but multiple burns areVarious shapes can be drawn, which allowed the scientist duo essentially to laser-print an ultracapacitor on graphene using consumer-grade technology
