Researchers synthesize graphene using intense light

DGIST Professor Yoonkyu Lee's research team used intense light on the surface of a copper wire to synthesize graphene, thereby increasing the production rate and lowering the production cost of the high-quality transparent-flexible ...

'Hot' graphene reveals migration of carbon atoms

The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on ...

Graphene-wrapped zeolite membranes for fast hydrogen separation

The effects of global warming are becoming more serious, and there is a strong demand for technological advances to reduce carbon dioxide emissions. Hydrogen is an ideal clean energy which produces water when burned. To promote ...

Wafer-scale production of graphene-based photonic devices

Our world needs reliable telecommunications more than ever before. However, classic devices have limitations in terms of size and cost and, especially, power consumption—which is directly related to greenhouse emissions. ...
