technological applications

Physicists at the University of Pennsylvania have demonstrated a new method by which graphene films can be etched along flawless, crystallographic axes using hot nanoparticles, a technique that results in precise, macroscopic length ribbons of graphene.

The advance could enable atomically precise and simple construction of integrated circuits from single graphene sheets with a wide range of technological applications.

A new study has advanced current understanding as well as the control of optical damage in crystals, offering new ways to increase light-power output of future optical integrated circuits.

Many of the lasers used today, both in scientific or technological applications have such a high light output power that the light itself damages or even destroys the crystals used to control, guide or manipulate it inside photonic devices (devices that only work with light).
