Quantum light source for eco-friendly production of biogas

Valuable substances from biomass – quantum cascade lasers offer some very interesting new possibilities

20-Mar-2025 - Much of our waste is far too valuable to simply be incinerated. If it is recycled in a carefully controlled way, not only can thermal energy be generated, but the resulting gas can also be used to produce valuable chemicals - from hydrogen to methane or methanol. However, the gas production ...

Seeing the invisible: A real life Eye of Sauron?

“That’s the idea here: an all-seeing eye that can detect hazardous aerosols against a very crowded background of other substances”

05-Apr-2024 - Picture this disaster scenario in the making: At an industrial plant, a pipe cracks, spraying a cloud of tiny droplets into the air. Workers, however, are in luck. Within minutes, a laser-based device the size of a small suitcase spots the cloud and tells safety crews what’s in it so they know ...

Intense lasers shine new light on the electron dynamics of liquids

A new spectroscopical tool to study liquids

02-Oct-2023 - The behavior of electrons in liquids determines a vast range of chemical processes and thus essential processes in organisms and the world as a whole. But electron movements are extremely hard to capture because they take place within attoseconds: the realm of quintillionths of a second. Since ...

Experiments reveal that water can “talk” to electrons in graphene

Results could lead to applications in water purification and desalination processes and maybe even to liquid-based computers

27-Jun-2023 - Water and carbon make a quantum couple: the flow of water on a carbon surface is governed by an unusual phenomenon dubbed quantum friction.A work published in ‘Nature Nanotechnology’ experimentally demonstrates this phenomenon – which was predicted in a previous theoretical study— at the ...
