Quan­tum physics turned into tan­gi­ble re­al­ity

ETH physicists have developed a silicon wafer that behaves like a topological insulator when stimulated using ultrasound. They have thereby succeeded in turning an abstract theoretical concept into a macroscopic product.

Conversion from bad fat to good fat

Scientists from ETH Zurich in Switzerland have shown for the first time that brown and white fat cells in a living organism can be converted from one cell type to the other. Their work, using mice as a model organism, provides ...

A material keyboard made of graphene

Researchers at ETH Zurich have succeeded in turning specially prepared graphene flakes either into insulators or into superconductors by applying an electric voltage. This technique even works locally, meaning that in the ...

Niacin, the fountain of youth

The vitamin niacin has a life-prolonging effect, as Michael Ristow has demonstrated in roundworms. From his study, the ETH-Zurich professor also concludes that so-called reactive oxygen species are healthy, not only disagreeing ...

Quantum computing machine under scrutiny

A new and innovative computing machine is currently attracting a great deal of attention in specialist circles. A team under the leadership of Matthias Troyer, a professor at ETH Zurich, has now confirmed that the machine ...

Glass from a 3-D printer

ETH researchers used a 3-D printing process to produce complex and highly porous glass objects. The basis for this is a special resin that can be cured with UV light.

Why lithium-ion-batteries fail

Materials in lithium ion battery electrodes expand and contract during charge and discharge. These volume changes drive particle fracture, which shortens battery lifetime. A group of ETH scientists together with colleagues ...

Going gentle on mechanical quantum systems

When thinking about quantum mechanical systems, single photons and well-isolated ions and atoms may spring to mind, or electrons spreading through a crystal. More exotic in the context of quantum mechanics are genuinely mechanical ...
