The researchers produced graphene sheets and applied a plasma treatment to them under argon (Ar), hydrogen (H 2), or oxygen (O 2) environments. This treatment "functionalized" graphene ...

Researchers at the Wyss Institute have developed a coating technology that improves the longevity of implantable and wearable ...

For example, could chemical tuning be used to alter the physical properties of graphene sheets? Indeed, could nanoelectronic devices be made from chemically functionalized graphene? Rather than ...

Small start-up companies are making large volumes of graphene, the world's thinnest material, for applications such as composites and electrodes. The exceptional electrical properties of graphene ...

Morphologies of the graphene-based air electrode. a, b) SEM images of as-prepared functionalized graphene sheets (FGS) (carbon/oxygen (C/O) = 14) air electrodes at different magnifications. c, d) ...

The team tested the device using aerosolized inactivated viruses to evaluate the performance of the sensor unit. The machine sampled the air continuously, providing a readout every 5 min, and ...
