Physicists produce stable water-based graphene dispersions

UmeƄ researchers show how activated graphene, activated carbons and other hydrophobic carbons can be dispersed in water in a form of micrometer-sized particles. The key agent that helps to make these dispersions last for ...

Graphene-based actuator swarm enables programmable deformation

Actuators that can convert various environmental stimuli to mechanical work have revealed great potential for developing smart devices such as soft robots, micro-electromechanical systems (MEMS), and automatic lab-on-a-chip ...

Graphene mapping 50 times faster

Graphene has created high expectations, as a strong, ultrathin, two-dimensional material that could also be the basis for new components in information technology. There is hence a huge need for characterization of graphene ...

Chemist develops flower-like catalysts from graphene

A RUDN chemist and colleagues from Iran have developed a new strategy for producing hollow, porous catalysts for the Heck coupling reaction. These catalysts are characterized by a flower-like structure. They consist of graphene, ...

Water was a winner in capturing carbon dioxide

Climate worries go hand in hand with CO2 emissions concerns. Emissions hit an all-time high last year. The CO2 level in the atmosphere may be higher than it's been in 3 million years.
