2D materials: to graphene and beyond
This review attempts to illustrate the different alternatives in the field of 2D materials (single-layers) from graphene to alternative inorganic materials such as metal chalcogenides, oxides, hydroxides, and metal–organic frameworks.

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.
