Friction Between Single Layer Graphene And An Atomic Force Microscope Tip

A technical paper titled “Dynamically tuning friction at the graphene interface using the field effect” was published by researchers at University of Illinois Urbana-Champaign and University of California Irvine. Abstract: "Dynamically controlling friction in micro- and nanoscale devices is possible using applied electrical bias between contacting surfaces, but this can also induce unwant... » read more

Optical constraints Stanford University researchers have discovered strong constraints to optical data transmission but hope it can guide future research in this area. As a reminder, optics, a form of data transmission that utilizes beams of light, has the promise to outperform the beams of electrons that drive computers or smartphones. And as engineers have long looked for a way to miniatu... » read more
