Quantum entanglement defies weightlessness
Quantum entanglement defies weightlessness
The ÖAW and TU Vienna were able to show during a parabolic flight: A change in gravity has no influence on quantum experiments . A team from the Austrian Academy of Sciences and the Vienna University of Technology was able to prove this during a flight with the European Space Agency: Quantum entanglement also works when the strength of gravity changes.

Clarified at last: the physics of popping champagne
Clarified at last: the physics of popping champagne
When you uncork a bottle of champagne, complex supersonic phenomena occur. Scientists at TU Wien have now been able to calculate exactly what happens for the first time. It sounds like a simple, well-known everyday phenomenon: there is high pressure in a champagne bottle, the stopper is driven outwards by the compressed gas in the bottle and flies away with a powerful pop.

Unconventional magnets: stress reduces frustration
Unconventional magnets: stress reduces frustration
An international research team recently demonstrated how magnetism can be actively changed by pressure. Magnetism occurs depending on how electrons behave. For example, the elementary particles can generate an electric current with their charge and thereby induce a magnetic field. However, magnetism can also arise through the collective alignment of the magnetic moments (spins) in a material.

Less waste thanks to mechanochemistry
"Chemistry is when it smokes and stinks" is an old saying. But green chemistry shows that things can be done differently . Green chemistry has been firmly established in research at TU Wien for more than a decade. With the inter-university Master's in Green Chemistry, it is now also gaining visibility in teaching.

Elastane recycling: Stretching the lifespan of textiles
Elastane recycling: Stretching the lifespan of textiles
Pleasant to wear, extremely unpleasant to recycle: elastane makes it difficult to reuse textiles. A solution has been found at TU Wien. Clothing is far too valuable to simply dispose of and burn. Starting in 2025, used textiles are to be collected and recycled throughout the EU. Improved recycling processes are urgently needed to deal with the huge amount of textiles that will then be produced in an efficient and environmentally friendly way.

Strangely 'quiet' current in strange metal
Strangely ’quiet’ current in strange metal
What happens when electric current flows through a "strange metal"- TU Wien (Vienna) and Rice University (Texas) show: The established picture of electrons and "quasi-electrons" collapses. At first glance, it all sounds so simple: there are electrons in a cable, and when we apply a voltage, the electrons dash from one side of the cable to the other, and an electric current flows.

Limits for quantum computers: perfect clocks are impossible
Limits for quantum computers: perfect clocks are impossible
It is becoming increasingly possible to carry out calculations with quantum computers. However, calculations by TU Wien show that there are fundamental limits - namely the quality of the clock used . There are different ideas on how to build quantum computers. But they all have one thing in common: you use a quantum physical system - for example individual atoms - and change their state by exposing them to very specific forces for a very specific time.

Two Conductors of a Chemical Reaction
Two Conductors of a Chemical Reaction
For the first time, researchers at TU Wien have successfully observed the operating principle of so-called promoters in a catalytic reaction in real-time. These promoters play an important role in technology, but so far there is only limited understanding of how they work. Catalysts are essential for numerous chemical technologies, ranging from exhaust gas purification to the production of valuable chemicals and energy carriers.

Aerosols: When scents influence our climate
One of the great unknowns in climate models is the behavior of certain gases that often smell strongly and cause water to condense. TU Wien (Vienna) is providing new insights into this. It has long been clear that man-made greenhouse gases are changing the climate - but there are still important details of climate change that are not well understood.

How Mega-Floods can be Predicted
How Mega-Floods can be Predicted
When floods are predicted only on the basis of local data, there may be unpleasant surprises. A new method makes it possible to significantly improve predictions - using international data from hydrologically similar areas. What can we expect in the worst-case scenario? In regions with a high risk of flooding, this is an important question: what extreme events should the protective measures be designed for? Often this is answered simply by looking at history: The worst flood events of the past decades or centuries are regarded as a realistic upper limit for what can be expected in the future.

Extreme sports: How Body and Mind Interact
Extreme sports: How Body and Mind Interact
Ciara Burns crossed the Atlantic in a rowing boat - and collected scientific data about her own body under stress. Now the scientific analysis of the results has been published. Ciara Burns spent 42 days rowing across the Atlantic in 2021 as part of a team of twelve. Clearly, whoever ventures on such an adventure has to go to the extreme limits both physically and mentally.

The Wild Boar Paradox - Finally Solved
The Wild Boar Paradox - Finally Solved
Decades after the Chernobyl nuclear accident, wild boar meat is still surprisingly radioactive. The solution to the riddle: an important other cause had been overlooked. The Chernobyl nuclear accident in 1986 had a major impact on the forest ecosystem in Central Europe. After the accident, the consumption of mushrooms was discouraged because of the high radioactive contamination, and the meat of wild animals was also severely affected for several years.

Graphene: Perfection is futile
Graphene: Perfection is futile
The carbon material graphene has excellent electronic properties. But are they also stable enough to be useful in practice? Calculations from TU Wien say: Yes. Nothing in the world is perfect. This is also true in materials research. In computer simulations, one often represents a system in a highly idealized way; for example, one calculates the properties that an absolutely perfect crystal would have.
