New graphene-based metasurface capable of independent amplitude and phase control of light

A KAIST research team in collaboration with the University of Wisconsin-Madison theoretically developed a graphene-based active metasurface capable of independent amplitude and phase control of mid-infrared light. This research gives a new insight into modulating the...

Tuning the interlayer spacing of graphene laminate films yields extremely efficient supercapacitors

Scientists from University College London and the Chinese Academy of Sciences have proposed a graphene-based design for supercapacitors, which reportedly increased their density by 10 times. Supercapacitors charge quickly but also discharge at a high speed. Existing...
Researchers determine if graphene promotes or prevents the corrosion of copper

Researchers determine if graphene promotes or prevents the corrosion of copper

Scientists from Chung-Ang University, Korea, led by Prof Hyungbin SonKorea, have observed a unique way in which graphene forms a hybrid layer that prevents copper corrosion. A challenge with using copper is that its surface oxidizes over time, even under ambient...
