Romania is one of the EU's largest methane emitters from oil and gas production facilities, but emissions have fallen sharply thanks to targeted information on leaks. An international research team led by Empa has shown that measurements not only reveal actual emissions, but also prompt companies to take action.

When fractions of a second make all the difference: researchers developed a process for manufacturing advanced thin films in which sophisticated timing enables high-quality functional layers at low process temperatures. The new method has applications in the semiconductor industry as well as in future quantum and photonics technologies.

Special care must be taken with illnesses during pregnancy, as not all drugs are compatible for mother and child. This is why an international research team involving Empa is now developing nanomedicines that will enable safe and effective treatment of inflammatory processes during pregnancy. Pregnancy complications are often caused or accompanied by inflammation, but the treatment options are often not sufficiently effective or are suspected of interfering with the development of the foetus.

Fungi are considered a promising source of biodegradable materials. researchers have developed a new material based on a fungal mycelium and its own extracellular matrix. This gives the biomaterial particularly advantageous properties. Sustainably produced, biodegradable materials are an important focus of modern materials science.

It is hardly surprising that green spaces in noisy cities offer people respite from stress. However, a comprehensive study by Empa and WSL shows for the first time for Switzerland how much these recreational spaces actually affect physical and mental stress management. More and more people are moving to cities, which means more traffic, denser living and less space for parks or other green areas.

An international team led by researchers from Empa and EPFL has explored how in future aerial robots could process construction materials precisely in the air - an approach with great potential for difficult-to-access locations or work at great heights.

Growing cells in the laboratory is an art that humans have mastered decades ago. Recreating entire three-dimensional tissues is much more challenging. researchers are developing a new hydrogel-based material that makes it possible to engineer artificial skin tissues, which can serve as living three-dimensional models of human skin for better understanding and treating skin diseases.

Antibiotic-resistant bacteria can cause life-threatening infections that are almost impossible to treat with existing medication.

Researchers are working on artificial muscles that can keep up with the real thing. They have now developed a method of producing the soft and elastic, yet powerful structures using 3D printing. One day, these could be used in medicine or robotics - and anywhere else where things need to move at the touch of a button.

Researchers have developed a new 3D tissue analysis for thyroid tumors. This special X-ray technique uses artificial intelligence to enable faster and more precise diagnoses.

Is it possible to tile a surface with a single shape in such a way that the pattern never repeats itself? In 2022, a mathematical solution to this "einstein problem" was discovered for the first time. researchers have now also found a chemical solution: a molecule that arranges itself into complex, non-repeating patterns on a surface.

The reproduction number R is often used as an indicator to predict how quickly an infectious disease will spread. researchers have developed a mathematical model that is just as easy to use but enables more accurate predictions than R. Their model is based on a reproduction matrix that takes into account the heterogeneity of society.

Mining the Atmosphere, a new Empa research initiative, aims at capturing excess CO2 from the atmosphere and storing it in building materials such as concrete.

Innosuisse, the Swiss innovation promotion agency, supports research-based innovation to strengthen the international competitiveness of Swiss industry. In projects, companies work together with universities or research institutes such as Empa to bring innovative ideas to the market. Empa is currently involved in around 80 such projects.

Sustainable, renewable and good for the climate: Wood is the material of the future. But how much of it do we actually have and how do we make best use of it? Researchers from Empa and WSL have now analyzed the material flows of wood in Switzerland in detail - and discovered untapped opportunities. Switzerland has set itself a goal that is as ambitious as it is necessary: net zero by 2050.

To achieve net zero, we need to reduce our CO2 emissions quickly and efficiently. An EU project involving Empa has selected Zurich as one of three pilot cities in Europe to accurately measure and model their carbon dioxide emissions. The findings will help cities to achieve their climate targets. Cities are the largest source of greenhouse gases in the world.

From smart textiles to self-driving cars: researchers are developing new types of detectors for infrared radiation that are more sustainable, flexible and cost-effective than conventional technologies. The key to success is not (only) the composition of the material, but also its size. The ubiquity of infrared detectors What do motion detectors, self-driving cars, chemical analyzers and satellites have in common' They all contain detectors for infrared (IR) light.

Since more and more deciduous trees are being planted in Swiss forests, whose wood is often burned directly, innovative ideas for a cascade use are in high demand in order to utilize Swiss hardwood more sustainably.

Robots that can sense touch and perceive temperature differences' An unexpected material might just make this a reality. At Empa's Laboratory for High-Performance Ceramics, researchers are developing soft and intelligent sensor materials based on ceramic particles. Most people think of coffee cups, bathroom tiles or flower pots when they hear the word "ceramic".
