Micro rubber: another polymer that pollutes our air and water

Rubber in the environment The tread on the tyre is worn out, new tyres are needed. Everyday life for many drivers. But where do these lost centimetres of tyre tread “disappear” to? As micro-rubbers, they mainly end up in soil and water and, to a small extent, in the air. And the amount of these Read more about Micro rubber: another polymer that pollutes our air and water[…]

New record for flexible thin-film solar cells

Never before has such an efficient flexible CIGS solar cell been built. Empa researchers achieve an efficiency of 20.8% for the first time – breaking their own record. Flexible solar cell with unprecedented efficiency: The Empa Laboratory for Thin Films and Photovoltaics, headed by Ayodhya N. Tiwari, has broken its own record. The researchers improved Read more about New record for flexible thin-film solar cells[…]

Record efficiency for a gas engine

At the end of May, the final meeting of the “Horizon 2020” project “GasOn” with the EU Commission took place in Brussels. The aim of this EU project was the further development of gas engines for cars and vans. Around 20 partners participated, including ETH Zurich and Empa as well as four European automobile manufacturers Read more about Record efficiency for a gas engine[…]

Bioplotter for novel implants

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 object shaped like a human ear from the 3D printer and explains: «In viscous state Read more about Bioplotter for novel implants[…]

Novel protective mask for medical personnel

Laughter is the best medicine, says medical research. But how are patients supposed to feel like smiling if the faces of the nursing staff and even their beloved ones are covered with masks? Researchers from Empa and EPFL are currently developing a novel face mask, which offers an unobstructed view of the wearer’s facial expressions. Read more about Novel protective mask for medical personnel[…]

Development of memory-steel brings new opportunities for old buildings

A new building material developed at Empa is about to be launched on the market: “memory-steel” can not only be used to reinforce new, but also existing concrete structures. When the material is heated (one-time), prestressing occurs automatically. The Empa spin-off re-fer AG is now presenting the material with shape memory in a series of Read more about Development of memory-steel brings new opportunities for old buildings[…]

Smart textiles will be used to treat skin wounds

Drug-releasing textiles could, for instance, be used to treat skin wounds. Empa researchers are currently developing polymer fibers that can be equipped with drugs. The smart fibers recognize the need for therapy all by themselves and dose the active ingredients with precision and accuracy. For the «Self Care Materials» project, fibers are produced from biodegradable Read more about Smart textiles will be used to treat skin wounds[…]

Joining process with reactive nano-multilayers

Reactive nano-multilayers are considered to be a revolution in joining technology. They are envisaged for joining heat-sensitive materials that would otherwise be damaged or even destroyed upon conventional soldering. But soldering with reactive foils proves to be tricky due to the volatile nature of the reactive foils. Empa researchers have now succeeded in refining the Read more about Joining process with reactive nano-multilayers[…]

Artificial Intelligence is set to trigger a major transformation in society

As soon as algorithms influence our voting habits or design school curricula, it is up to politics to limit the damage. A new study on the opportunities and risks of AI is now being conducted on behalf of TA-Swiss. Artificial intelligence (AI) is not just about the irritatingly charming face of a “humanoid robot” gazing Read more about Artificial Intelligence is set to trigger a major transformation in society[…]

Step by step to the perfect and sustainable pavement

The one ideal asphalt for all conditions does not exist: climatic conditions, traffic frequencies and loads place different demands on the pavement. Another challenge: preparing old asphalt so that it can be used for new pavements. Thanks to Empa researchers, the design of the ideal asphalt for every type of road has finally become easier. Read more about Step by step to the perfect and sustainable pavement[…]

Window glass that transmits light optimally but keeps the heat outside: a dream of many architects

Summer. Blue sky. Sunshine. But you don’t notice much of it in the office or in your home, because the blinds block the view so that the heat stays outside. This scenario could soon be a thing of the past: EPFL researchers are working with Empa on a window glass that keeps out the heat Read more about Window glass that transmits light optimally but keeps the heat outside: a dream of many architects[…]

Gas station of the future

What could a “gas station of the future” look like?

What services does it offer? Which fuels can be refueled there and where do they come from? Possible answers to these questions can be found at the stand of the of Swiss Oil Industry Association (Erdöl-Vereinigung) at the Geneva Motor Show. The stand in Hall 6 is run in cooperation with Empa and Hyundai. In Read more about What could a “gas station of the future” look like?[…]
