Single-step synthesis and magnetic separation of graphene and carbon nanotubes in arc discharge plasmas

Simultaneous production of graphene flakes and carbon nanotubes in arc discharge, followed by the effective magnetic separation and deposition at different surfaces is demonstrated by splitting the high-temperature growth and low-temperature separation zones of the discharge using a non-uniform magnetic field and custom-designed catalyst.

Self-aligned nanolithography by selective polymer dissolution

We report a novel nanolithography technique for self-aligned polymer patterning on metallic nanowires and graphene ribbons. We show that by dissolution of polymers through localized heating, nanoscale trench structures can be fabricated to selectively expose the underlying conductive material, providing potential use for site-specific modification or functionalization of nanostructure devices.
