The Wood Paradox

“It can be deformed as required and is three times stronger than natural wood: the wood material developed by Marion Frey, Tobias Keplinger and Ingo Burgert at Empa and ETH Zurich has the potential to become a high-tech material. In …

Next generation of watch springs

“What happens when something keeps getting smaller and smaller? This is the type of question Empa researcher Johann Michler and his team are investigating. As a by-product of their research completely novel watch springs could soon be used in Swiss …

How to program materials

“Can the properties of composite materials be predicted? Empa scientists have mastered this feat and thus can help achieve research objectives faster. This leads, for instance, to better recycling techniques and electrically conductive synthetic materials for the solar industry. Ali …

How safe is graphene?

“Graphene is considered one of the most interesting and versatile materials of our time. The application possibilities inspire both research and industry. But are products containing graphene also safe for humans and the environment? A comprehensive review, developed as part …

Ears from the 3D-printer

“Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing. It all starts with an ear. Empa researcher Michael Hausmann removes the …

A burst of “synchronous” light

“Excited photo-emitters can cooperate and radiate simultaneously, a phenomenon called superfluorescence. Researchers from Empa and ETH Zurich, together with colleagues from IBM Research Zurich, have recently been able to create this effect with long-range ordered nanocrystal superlattices. This discovery could …

Quantum chains in graphene nanoribbons

“Empa researchers, together with colleagues from the Max Planck Institute for Polymer Research in Mainz and other partners, have achieved a breakthrough that could in future be used for precise nanotransistors or – in the distant future – possibly even quantum computers …

An unlikely marriage among oxides

“Sebastian Siol is looking for new materials with unusual properties that were so far not accessible in experiments. To do this, he connects partners who don’t really fit together: One partner forces the other into a state that would …

A step towards cheap aluminium batteries

“The energy transition depends on technologies that allow the inexpensive temporary storage of electricity from renewable sources. A promising new candidate is aluminium batteries, which are made from cheap and abundant raw materials. Scientists from Maksym Kovalenko’s research group …

A nanotransistor made of graphene

“Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years’ time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a …

The stacked color sensor

“Red-sensitive, blue-sensitive and green-sensitive color sensors stacked on top of each other instead of being lined up in a mosaic pattern – this principle could allow image sensors with unprecedented resolution and sensitivity to light to be created. However, so far …
