Powerful graphene hybrid material for highly efficient supercapacitors — ScienceDaily

A team working with Roland Fischer, Professor of Inorganic and Metal-Organic Chemistry at the Technical University Munich (TUM) has developed a highly efficient supercapacitor. The basis of the energy storage device is a novel, powerful and also sustainable graphene hybrid material that has comparable performance data to currently utilized batteries. Usually, energy storage is associated […]

Graphene balloons to identify noble gases

Credit: TU Delft/Makars Šiškins New research by scientists from Delft University of Technology and the University of Duisburg-Essen uses the motion of atomically thin graphene to identify noble gasses. These gasses are chemically passive and do not react with other materials, which makes it challenging to detect them. The findings are reported in the journal […]

No losses: Scientists stuff graphene with light

IMAGE: Header Image view more  Credit: Daria Sokol/MIPT Press Office Physicists from MIPT and Vladimir State University, Russia, have achieved a nearly 90% efficiency converting light energy into surface waves on graphene. They relied on a laser-like energy conversion scheme and collective resonances. The paper came out in Laser & Photonics Reviews. Manipulating light at the […]

Team finds path to nanodiamond from graphene

Rice University researchers have expanded their theory on converting graphene into 2D diamond, or diamane. They have determined that a pinpoint of pressure can trigger connections between layers of graphene, rearranging the lattice into cubic diamond. Credit: Pavel Sorokin Marrying two layers of graphene is an easy route to the blissful formation of nanoscale diamond, […]

On-surface synthesis of graphene nanoribbons could advance quantum devices

Scientists synthesized graphene nanoribbons, shown in yellow, on a titanium dioxide substrate, in blue. The lighter ends of the ribbon show magnetic states. The inset drawing shows how the ends have up and down spin, suitable for creating qubits. Credit: ORNL, U.S. Dept. of Energy An international multi-institution team of scientists has synthesized graphene nanoribbons—ultrathin […]
