The Mechanics of the Immune System
The Mechanics of the Immune System
When T-cells of our immune system become active, tiny traction forces at the molecular level play an important role. They have now been studied at TU Wien. Highly complicated processes constantly take place in our body to keep pathogens in check: The T-cells of our immune system are busy searching for antigens - suspicious molecules that fit exactly into certain receptors of the T-cells like a key into a lock.

Stable Catalysts for New Energy
Stable Catalysts for New Energy
Crucial new technologies such as hydrogen production or carbon capture require new catalysts. Experiments show: It's not just the material that matters, but also its atomic surface structure. On the way to a CO2-neutral economy, we need to perfect a whole range of technologies - including the electrochemical extraction of hydrogen from water, fuel cells, or carbon capture.

Sweet taste reduces appetite?
Sweet taste reduces appetite?
The sweet taste of sugar, energy intake and the regulatory process of hunger and satiety To date, very little is known about how sweetness perception contributes to satiety. This study, conducted by an Austrian-German team led by chemists Veronika Somoza and Barbara Lieder, provides new insights into the relationship between the sweet taste of sugar, energy intake and the regulatory process of hunger and satiety.

Machine learning methods provide new insights into organic-inorganic interfaces
Machine learning methods provide new insights into organic-inorganic interfaces
Simulations at Graz University of Technology refute earlier theories on long-range charge transfer between organic and inorganic materials. Oliver Hofmann and his research group at the Institute of Solid State Physics at TU Graz are working on the optimization of modern electronics. A key role in their research is played by interface properties of hybrid materials consisting of organic and inorganic components, which are used, for example, in OLED displays or organic solar cells.

Graphene: It is all about the toppings
Graphene: It is all about the toppings
To fully exploit the potential of the "wonder material" graphene, it has to be combined with other materials. A new study investigates what is important for this. Graphene consists of a single layer of carbon atoms. Exceptional electronic, thermal, mechanical and optical properties have made graphene one of the most studied materials at the moment.

TU Graz researchers want to fundamentally improve concrete diagnostics
Under the scientific direction of Graz University of Technology, an Austrian consortium is working on new investigation methods for rapid and precise assessments of concrete structures. Additional at the end of the text Whether crumbling tunnel walls, cracks in concrete facades or porous bridge piers, according to statistics from the National Association of Corrosion Engineers (NACE), damage to concrete structures caused by various environmental influences accounts for several billion euros worldwide every year.

Taking a deep look into animals
Taking a deep look into animals
Advances in neuroscience research and microscopy: Researchers look deep into organs and nervous systems of animals, ranging from squids and worms to fish and salamanders. Analyses of individual cells in the context of whole organs or tissues is becoming increasingly important in biology. A standard approach so far was to cut larger tissues into thin layers, study each of these sections, and then piece the information again together into a 3D model.

Superconductivity: It's Hydrogen's Fault
Superconductivity: It’s Hydrogen’s Fault
Nickel is supposed to herald a new age of superconductivity - but this is proving more difficult than expected. Scientists at TU Wien (Vienna) can now explain why. Last summer, a new age for high-temperature superconductivity was proclaimed - the nickel age. It was discovered that there are promising superconductors in a special class of materials, the so-called nickelates, which can conduct electric current without any resistance even at high temperatures.

Water replaces toxins: Green production of plastics
Water replaces toxins: Green production of plastics
Although organic plastics are not harmful to the environment themselves, toxic substances are often used during their synthesis. TU Wien shows - there is another way. Many materials that we use every day are not sustainable. Some are harmful to plants or animals, others contain rare elements that will not always be as readily available as they are today.

Antibiotic matter waves
Antibiotic matter waves
One of the central tenets of quantum mechanics is the wave-particle duality. It tells us that even massive objects behave like both particles and waves. A number of previous experiments have shown this for electrons, neutrons, atoms and even large molecules. Quantum theory maintains that this is a universal property of matter.
