Light green hydrogen will do

“It would be counterproductive to aim for complete decarbonisation, as the excessive costs could slow down the energy transition”

04-Jul-2024 - Whether sustainably produced hydrogen needs to be 100 percent green is currently under debate. Using the production of ammonia and artificial fertiliser as examples, researchers have calculated that "nearly sustainable" hydrogen would be better in the end. There’s a role for sustainably produced ...

Electron vortices in graphene detected

“Thanks to our extremely sensitive sensor and high spatial resolution, we didn’t even need to cool down the graphene...”

14-May-2024 - Researchers at ETH Zurich have, for the first time, made visible how electrons form vortices in a material at room temperature. Their experiment used a quantum sensing microscope with an extremely high resolution. When an ordinary electrical conductor – such as a metal wire – is connected to a ...
