Researchers show that the terahertz nonlinearity of graphene can be efficiently controlled using minimal electrical gating

A team of researchers from Bielefeld and Berlin, together with researchers from other research institutes in Germany and Spain, recently demonstrated that graphene’s nonlinearity can be efficiently controlled by applying comparatively modest electrical voltages...
“Flash Graphene” process modified to produce graphene from rubber waste

“Flash Graphene” process modified to produce graphene from rubber waste

The “flash” process, introduced by Tour and his colleagues at Rice University in 2020, has now been optimized to convert waste from rubber tires into graphene that can, in turn, be used to strengthen concrete.The atoms reassemble into valuable turbostratic graphene,...

Researchers produce extremely conductive graphene-enhanced hydrogel for medical applications

An interdisciplinary research team of the Research Training Group (RTG) 2154 “Materials for Brain” at Kiel University (CAU) has developed a method to produce graphene-enhanced hydrogels with an excellent level of electrical conductivity. What makes this...

Researchers find surprising electron interaction in ‘magic-angle’ graphene

A research team, led by Brown University physicists, has found a new way to precisely probe the nature of the superconducting state in magic-angle graphene. The technique enables researchers to manipulate the repulsive force – the Coulomb interaction – in...

Novel tin/graphene electrode could enable next-gen supercapacitors

An international collaboration of researchers from Penn State and the University of Electronic Science and Technology of China has resulted in a novel material for supercapacitors’ electrodes.“The supercapacitor is a very powerful, energy-dense device with a...

Graphene oxide helps achieve efficient air processed perovskite solar cells via scalable technique

A research team, led by Dr. Luigi Angelo Castriotta at the at University of Rome Tor Vergata’s CHOSE Center for Hybrid and Organic Solar Energy, has reported impressive results on methylammonium free perovskites processed in air, using a scalable technique based...
