Tracking down the smallest particles
Tracking down the smallest particles
Nanomaterials consist of tiny particles of different composition. They are used, for example, in textiles and can enter aquatic systems directly from the factory, while being worn or disposed of. For years, research groups at Eawag have been investigating the effects of artificially manufactured nanoparticles on human beings and the environment.

Bringing the heat out of the city
Bringing the heat out of the city
Heat waves are increasing worldwide - and that includes Switzerland. Cities in particular suffer as a result: the temperature difference between city and countryside can amount to several degrees.

Silicon-perovskite solar cells achieve record efficiency of 25,2%
Silicon-perovskite solar cells achieve record efficiency of 25,2%
In Neuchâtel (Switzerland), researchers from EPFL and CSEM have combined siliconand perovskite-based solar cells. The resulting efficiency of 25.2% is a record for this type of tandem cell. Their innovative yet simple manufacturing technique could be directly integrated into existing production lines, and efficiency could eventually rise above 30%.

So that Ronaldo and Co. can «conjure»
So that Ronaldo and Co. can «conjure»
The official ball for the 2018 FIFA World Cup in Russia has received Empa's «OK» after numerous tests. Some goalkeepers may be critical of its flight characteristics, but the reason for their criticism may lie somewhere else - the rather unconventional appearance of the new ball. Football lives on emotions.

An elastic fiber set to revolutionize smart clothes
EPFL scientists have found a fast and simple way to make super-elastic, multi-material, high-performance fibers. Their fibers have already been used as sensors on robotic fingers and in clothing. This breakthrough method opens the door to new kinds of smart textiles and medical implants. It's a whole new way of thinking about sensors.

«Research should be fun»
«Research should be fun»
Research should set things in motion. This is the motto of Matthias Koebel, Head of Empa's Building Energy Materials and Components lab. The chemist has ambitious goals and successfully combines an inquisitive spirit with entrepreneurial flair. Matthias Koebel is a pragmatic. One who not only understands things but also wants to use them.

Ultrafiltration without pressure - the power of gravity
Ultrafiltration without pressure - the power of gravity
Ultrafiltration is one of the techniques currently used for disinfecting water - viruses and bacteria are reliably retained by a membrane with extremely small pores. For more than ten years, Eawag has successfully been carrying out research to determine how this method can function using the effect of gravity on water instead of high pressure, cleaning and chemicals.

Through the pores into the skin
Through the pores into the skin
Even if the wound looks superficially harmless, steam burns must be cooled persistently. Empa researchers have now been able to show for the first time how hot steam achieves its vicious effect: It penetrates the upper skin layer and can cause severe burns in the lower skin layers - initially almost invisible.

Sun protection without blinds
Sun protection without blinds
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.

One step further towards cheap aluminium
One step further towards cheap aluminium
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, which is based at both ETH Zurich and in Empa's Laboratory for Thin Films and Photovoltaics , are researching and developing batteries made from abundant raw materials.

Bandage with a voice
Bandage with a voice
A novel bandage alerts the nursing staff as soon as a wound starts healing badly. Sensors incorporated into the base material glow with a different intensity if the wound's pH level changes. This way even chronic wounds could be monitored at home. All too often, changing bandages is extremely unpleasant, even for smaller, everyday injuries.

A retinal implant that is more effective against blindness
EPFL researchers have developed a new type of retinal implant for people who have become blind due to the loss of photoreceptor cells in their retinas. The implant partially restores their visual field and can significantly improve their quality of life. Thirty-two million people around the world are blind.

A treasure trove for nanotechnology experts
A treasure trove for nanotechnology experts
A team from EPFL and NCCR Marvel has identified more than 1,000 materials with a particularly interesting 2D structure. Their research, which made the cover page of Nature Nanotechnlogy, paves the way for groundbreaking technological applications. 2D materials, which consist of a few layers of atoms, may well be the future of nanotechnology.

Controlling skyrmions with lasers
EPFL scientists have produced controllable stable skyrmions using laser pulses, taking a step towards significantly more energy-efficient memory devices. The work is published in Physical Review Letters. A skyrmion is a collection of electron spins that look like a vortex in certain magnetic materials.

Sinfonia ai funghi
Sinfonia ai funghi
Do violins made of wood that had been treated with fungi sound the same as a fine, antique instrument? Acoustics experts at Empa are currently studying the body and soul of instruments made of "mycowood". Precision structure-borne sound measurements and psycho-acoustic tests with volunteers should reveal whether a fungal treatment can really improve an instrument.

Revealing the hidden path of perovskite formation
Revealing the hidden path of perovskite formation
EPFL scientists systematically study the path of the sequential deposition reaction used to build perovskite solar panels. The study is published in Science Advances and offers much-needed, fundamental understanding of perovskite formation and its different stages. Image:  Scanning electron microscope (SEM) image showing the formation of methylammonium lead iodide perovskite (CH3NH3PbI 3 ) by the reaction of lead iodide (PbI 2 ) films with methylammonium iodide (CH3NH3I) solution for 2 seconds in the dark.

A ski jacket that actively gets rid of
To keep the body warm and dry during winter sports, high-performance clothing is a must. The demands on these textiles are high, as a person sweats up to one liter per hour on his upper body alone when skiing.
