Stellar winds of three sun-like stars detected for the first time
Astrophysicists were able to quantify the mass loss of stars via their stellar winds An international research team led by a researcher from the University of Vienna has for the first time directly detected stellar winds from three Sun-like stars by recording the X-ray emission from their astrospheres, and placed constraints on the mass loss rate of the stars via their stellar winds.

Novel UV Broadband Spectrometer Revolutionises Air Pollutant Analysis
Novel UV Broadband Spectrometer Revolutionises Air Pollutant Analysis
The laser-based technology developed at TU Graz enables the continual real-time analysis of air pollutants and their interaction with other gases and sunlight. Sunlight has a major influence on chemical processes. Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of the substances present in the air.

A new type of cooling for quantum simulators
A new type of cooling for quantum simulators
More stable quantum experiments are made possible at TU Wien with new tricks - by ingeniously splitting Bose-Einstein condensates. Quantum experiments always have to deal with the same problem, regardless of whether they involve quantum computers, quantum teleportation or new types of quantum sensors: quantum effects break down very easily.

A self-cleaning wall paint
A self-cleaning wall paint
A breakthrough in catalysis research leads to a new wall paint that cleans itself when exposed to sunlight and chemically breaks down air pollutants. Typically, beautiful white wall paint does not stay beautiful and white forever. Often, various substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while - but over time, the colour changes and needs to be renewed.

New Method for Analysing Nanoporous Materials
New Method for Analysing Nanoporous Materials
Using only a single electron microscope image, researchers at TU Graz can determine the type and exact position of so-called guest atoms in high-tech materials. They also come closer to solving the mystery of the blue colour of aquamarine. In addition to their main components, the properties of crystalline and nanoporous materials often depend crucially on guest atoms or ions that are embedded in the tiny pores of their lattice structure.

Holographic message encoded in simple plastic
Holographic message encoded in simple plastic
Important data, such as a Bitcoin wallet address, can be stored and concealed quite easily in ordinary plastic using 3D printers and terahertz radiation, scientists at TU Wien show. There are many ways to store data - digitally, on a hard disk, or using analogue storage technology, for example as a hologram.

Ultra-short light pulses enable high-precision 'artificial nose'
Ultra-short light pulses enable high-precision ’artificial nose’
A new spectroscopy method has been developed at TU Wien: Using a series of laser pusles, chemical analyses can be carried out much faster and more precisely than before. Whether you want to analyze environmental samples in nature or monitor a chemical experiment, you often need highly sensitive sensors that can "sniff out" even tiny traces of a certain gas with extreme accuracy.

Can quantum computers help in the development of new drugs?
Scientists predict that quantum computers will be able to discover drugs faster than conventional computers in the future Quantum computers have promising potential applications. One potential area of application is computer-aided research and development of new drugs. A team from the University of Vienna, together with researchers from Boehringer Ingelheim, BASF, Google, QC Ware and the University of Toronto, have investigated the possibilities of this technology in a review article published in the journal Nature Physics .

Network of quantum sensors increases precision
Network of quantum sensors increases precision
Quantum sensor technology promises even more precise measurements of physical quantities. A team led by Christian Roos at the University of Innsbruck has now compared the signals of up to 91 quantum sensors with each other and thus successfully suppressed the noise caused by interactions with the environment.

TU Graz Develops Innovative Coating against Ice
TU Graz Develops Innovative Coating against Ice
The material delays the formation of ice crystals and reduces the adhesion of ice layers. Thanks to an innovative production method, the coating is very robust and adheres to numerous surfaces. Ice-repellent coatings have been around for some time, but until now they have been very sensitive and detach quite quickly from the surfaces they are meant to protect.

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.

Spintronics: the electronics of the future could be antiferromagnetic
It is an important step forward in spintronics: the magnetic state of certain materials can be switched using surface induced strain. All our electronics are based on electrical charges being transported from one place to another. Electrons move, current flows, signals are transmitted by applying an electrical voltage.

New technique visualises mechanical structure of the cell nucleus for the first time
The cell nucleus is considered to be the control centre of vital cellular processes, but its material properties continue to puzzle scientists. An international research team led by MedUni Vienna has now developed a new technique that provides a previously unattainable view of the mechanical properties inside this control centre.

TU Graz Researchers Optimize 3D Printing of Optically Active Nanostructures
The shape, size and optical properties of 3-dimensional nanostructures can now be simulated in advance before they are produced directly with high precision on a wide variety of surfaces. For around 20 years, it has been possible to modify surfaces via nanoparticles so that they concentrate or manipulate light in the desired way or trigger other reactions.

Obser­ving macros­co­pic quan­tum effects in the dark
Be fast, avoid light, and roll through a curvy ramp: This is the recipe for a pioneering experiment proposed by theoretical physicists in a recent paper published in Physical Review Letters. An object evolving in a potential created through electrostatic or magnetic forces is expected to rapidly and reliably generate a macroscopic quantum superposition state.

The rock that creates clouds
Feldspar is very common in rocks. As atmospheric dust, this mineral contributes efficiently to cloud formation. Researchers at TU Wien have now discovered what happens during this process. Feldspar is a ubiquitous mineral and makes up about half of the Earth's crust. In the Earth's atmosphere, feldspars play a surprisingly important role.
