New chemical method could revolutionize graphene use in electronics

Adding a molecular structure containing chromium, carbon, and oxygen atoms retains graphene's conductive properties. The metal atom (silver, in this experiment) to be bonded are then added to the oxygen atom on top. (credit: Songwei Che et al./Nano Letters)

Graphene-based computer would be 1,000 times faster than silicon-based, use 100th the power

High-speed light-based systems could replace supercomputers for certain ‘deep learning’ calculations

Low power requirements for photons (instead of electrons) may make deep learning more practical in future self-driving cars and mobile consumer devices
