Researchers from the University of Nebraska-Lincoln developed a chemical process to produce graphene nanoribbons (GNRs). This bottom-up method can be used to produce very narrow GNRs (2 nanometers wide). The researchers say it is easy to scale up their process.

The team is now testing their ribbons for applications in electronics, gas sensors and solar cells. The electronic properties of their GNRs can be tuned by changing the synthetic conditions.
