Findings could have applications in high-speed communications fields.

Graphene, a stable two-dimensional structure, has attracted tremendous worldwide attention in recent years because of its unique electronic, physical and mechanical properties as well as its wide range of applications.

Multi-walled carbon nanotubes riddled with defects and impurities on the outside could replace some of the expensive platinum catalysts used in fuel cells and metal-air batteries, according to scientists at Stanford University.

A collaboration of three groups is responsible for creating and imaging the smallest structure ever -- a billionth of a meter across and nearly 100,000 times thinner than a human hair.

A new study shows that the availability of hydrogen plays a significant role in determining the chemical and structural makeup of graphene oxide, a material that has potential uses in nano-electronics, nano-electromechanical systems, sensing, composites, optics, catalysis and energy storage.
