Joined nano-triangles pave the way to magnetic carbon materials
Joined nano-triangles pave the way to magnetic carbon materials
Graphene triangles with an edge length of only a few atoms behave like peculiar quantum magnets. When two of these nano-triangles are joined, a "quantum entanglement" of their magnetic moments takes place: the structure becomes antiferromagnetic. This could be a breakthrough for future magnetic materials, and another step towards spintronics.

Caught in flight
Caught in flight
Humans are exposed to numerous harmful environmental influences, and it is an international concern to quantify these emissions as accurately as possible in order to be able to take measures to contain them. Empa is also part of these efforts and has, among other things, developed a drone equipped with state-of-the-art measuring instruments which can detect methane leaks.

Hot off the Oven
Hot off the Oven
During metal processing in the 3D laser printer, temperatures of more than 2,500 degrees Celsius are reached within milliseconds, causing some components of the alloys to evaporate. While widely considered a problem inherent to the process, Empa researchers spotted an opportunity - and are now using the effect to create new alloys with novel properties and embed them in 3D-printed metallic work pieces with micrometer precision.

The Transistor out of the Printer
The Transistor out of the Printer
A new revolution in the production of electronic circuits is on the way: Empa researchers are working on electronics that come out of printers. This makes it possible to produce the circuits on all sorts of substrates, such as paper or plastic film - but there are still some hurdles to overcome. Imagine being able to easily print electronics on any surface.

When Concrete learns to pre-stress itself
When Concrete learns to pre-stress itself
Concrete is by far the most widely used building material in the world - and the trend is rising. Using a new type of concrete formula, an Empa team has succeeded in producing self-prestressed concrete elements. This innovation makes it possible to build lean structures much more cost-effectively - and save material at the same time.

Wearable Health
There is more than cool looks about hip clothing for top performance: Thanks to a variety of smart technologies, high-tech clothing today is capable of analyzing body functions or actively optimizing the microclimate. The basis of these novel textiles are "smart" fibers and biocompatible composites that also contribute to innovations in biomedical research such as sensors, drug delivery systems or tissue engineering.

Platinum keeps Fruit fresh
Platinum keeps Fruit fresh
If different types of vegetables and fruits are stored together, they influence each other in the ripening process. This is due to ethylene, which is emitted by some plant-based foodstuff and accelerates ripening. To prevent excessive food waste due to accelerated ripening Empa and ETH Zurich researchers are developing a new catalyst that degrades ethylene into water and carbon dioxide.

Using electrical stimulus to regulate genes
Using electrical stimulus to regulate genes
A team of researchers has succeeded in using an electric current to directly control gene expression for the first time. Their work provides the basis for medical implants that can be switched on and off using electronic devices outside the body. This is how it works. A device containing insulin-producing cells and an electronic control unit is implanted in the body of a diabetic.

Mapping Immune Cells in Brain Tumors
Mapping Immune Cells in Brain Tumors
It is not always possible to completely remove malignant brain tumors by surgery so that further treatment is necessary. Researchers from the University of Zurich and the UniversityHospital Zurich have now been able to describe, with unparalleled precision, the composition of the immune cells of various types of brain tumors.

Geneva study against SARS-CoV-2 gets underway
Geneva study against SARS-CoV-2 gets underway
Geneva University Hospitals (HUG), the University of Geneva , the Infectious Disease Research Centre at Laval University in Quebec (Canada) and MaxiVAX - a Geneva-based company specialising in biotechnology - are working together to develop a SARS-CoV-2 vaccine. This joint research programme aims to create a vaccine combining an immunostimulator and a specific coronavirus target, namely the spike surface protein.

Confirmation of Earth-sized planet around the nearest star
Confirmation of Earth-sized planet around the nearest star
The existence of an Earth-sized planet around the nearest star in the solar system, Proxima Centauri, has been confirmed by an international team of scientists including researchers from the University of Geneva. The results, published in the journal Astronomy & Astrophysics, reveal that the planet in question, Proxima b, has a mass of 1.17 Earth masses and is located in the habitable zone of its star, which it circles in 11.2 days.

A tightrope walk for fresh air
A tightrope walk for fresh air
At 3500 meters above sea level, research is sometimes quite adventurous. In order to be able to supply Empa's air analysis station on the Jungfraujoch with "clean" samples, a team of researchers and professional climbers installed a new air intake - 50 meters outside the station on a narrow ridge above the abyss.

Estimating the second wave
Estimating the second wave
ETH researchers are using a new mathematical model to calculate a possible second wave of the pandemic in Switzerland. Even though such a wave would probably grow more slowly than the first without overloading hospitals, its death toll may turn out to be significantly higher. Should Switzerland see a second wave of the coro rus pandemic, it would proceed more slowly than the first.

Mathematics can save lives at sea
An international research collaboration led by ETH Zurich and MIT has developed a mathematical method that can speed up search and rescue operations at sea. The new algorithm accurately predicts locations to which objects and people floating in water will drift. Hundreds of people die at sea every year due to vessel and airplane accidents.

Wild Bees Fly for Research
Wild Bees Fly for Research
What stresses wild bees? Is it certain plant-protection products, the absence of nutrient-rich foods - or a combination of both factors? Together with research partners throughout Europe, Agroscope is investigating these issues. Of the total proceeds from agriculture in Switzerland, around CHF 350 million a year are only generated due to the pollination performance of honeybees and wild bees.

Increased Usability and Precision in Vascular Imaging
Increased Usability and Precision in Vascular Imaging
Researchers at the University of Zurich have developed a new X-ray contrast agent. The contrast agent is easier to use and distributes into all blood vessels more reliably, increasing the precision of vascular imaging. This reduces the number of animals required in research experiments. Various diseases in humans and animals - such as tumors, strokes or chronic kidney disease - damage the blood vessels.

Even natural products can be harmful for the unborn child
Plant products ingested by pregnant women through their diet are broken down by the intestinal microbiota into chemical substances, some of which can cross the placental barrier and reach the fetus. These foreign substances can harm the unborn child, even if they are of "natural origin". Researchers at the Department for BioMedical Research (DBMR) at the University of Bern and Inselspital, University Hospital Bern, therefore warn against underestimating the effects of such substances.
