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.

Artificial cartilage with the help of 3D printing
Artificial cartilage with the help of 3D printing
A new approach to producing artificial tissue has been developed at TU Wien: Cells are grown in microstructures created in a 3D printer. Is it possible to grow tissue in the laboratory, for example to replace injured cartilage? At TU Wien (Vienna), an important step has now been taken towards creating replacement tissue in the lab - using a technique that differs significantly from other methods used around the world.

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.

In Search of the Perfect Mirror at Mid-Infrared Wavelengths
Advanced infrared mirrors enhance climate and biofuel research via precision trace gas sensing. An international team of researchers from the United States, Austria, and Switzerland has demonstrated the first true supermirrors in the mid-infrared spectral region. These mirrors are key for many applications, such as optical spectroscopy for environmental sensing, as well as laser cutting and welding for manufacturing.

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.

A Longer Life for Organic Solar Cells
A Longer Life for Organic Solar Cells
By Philipp Jarke Photovoltaic cells made of organic materials are light and flexible, which is why they are considered very promising. An international research network led by TU Graz is now aiming to increase the stability of the materials. Solar cells made of silicon have been around for 70 years. Organic solar cells, on the other hand, are quite new, but open up new possibilities for emission-free electricity production.

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.

Hope for revolutionary high-temperature superconductor lives on
Hope for revolutionary high-temperature superconductor lives on
Calculations by TU Wien (Vienna) show: Newly discovered material LK-99 indeed has properties that could be advantageous for superconductivity. LK-99 is the name of the material that is being hotly debated around the world these days: A Korean research group published results at the end of July 2023 suggesting that it could be a superconductor even at room temperature and normal atmospheric pressure.

Heat pad for houses
Heat pad for houses
The heating and cooling requirements of residential buildings account for around a quarter of total energy consumption worldwide. This is where the BIO-NRG-STORE research project at the Kuchl Campus of the Salzburg University of Applied Sciences comes in. An international team is researching how the use of biogenic materials can achieve a reduction in energy consumption.

High-tech lubricant forms by itself when needed
Lubricants that reduce friction are created precisely where friction is high: At TU Wien, this was achieved with special 2D materials. This is important for space technology . Our bodies have a few things in common with machines: we have moving joints, friction and wear occur, so you need suitable lubricants.

New Ceramics for Electronics and Energy Conversion
New Ceramics for Electronics and Energy Conversion
By Birgit Baustädter Jurij Koruza and his team are working on electroceramics that are used in electronic devices. The team is part of a new and highly endowed collaborative research centre led by TU Darmstadt. Electroceramics are at the core of many electronic components. A mobile phone, for example, contains about 500 capacitors consisting of several layers of ceramic and metal.

The quantum spin liquid that isn't one
The quantum spin liquid that isn’t one
The simplest explanation is often the best - this also applies to fundamental science. Researchers from TU Wien and Toho University recently showed that a supposed quantum spin liquid can be described by more conventional physics. For two decades, it was believed that a possible quantum spin liquid was discovered in a synthetically produced material.

Ceramic coatings do not fatigue
Ceramic coatings do not fatigue
What determines the durability of high-performance coatings for turbines or highly stressed tools? Surprising results from TU Wien show: It is not material fatigue. Extremely thin ceramic coatings can completely change the properties of technical components. Coatings are used, for example, to increase the resistance of metals to heat or corrosion.

Growth of Nanoholes Visible for the First Time Thanks to Helium Scattering
By Birgit Baustädter Scientists at TU Graz in cooperation with the University of Surrey were able to observe and document the growth of hexagonal boron nitride for the first time. The material is mainly used in microelectronics and nanotechnology. Atomically thin 2D materials for applications in microelectronics or nanotechnology are grown by breaking down gas on a hot metal surface.

Topological Materials Become Switchable
Topological Materials Become Switchable
Because they are extremely stable, so-called "topological states" play an important role in materials research. Now, for the first time, it has been possible to switch such states on and off. A donut is not a breakfast roll. Those are two very clearly distinguishable objects: One has a hole, the other does not.

Faster friction - less wear
Faster friction - less wear
A seemingly paradoxical effect: friction normally causes more damage at higher speeds. But at extremely high speeds, it is the other way around. When two metal surfaces slide against each other, a variety of complicated phenomena occur that lead to friction and wear: Small crystalline regions, of which metals are typically composed, can be deformed, twisted or broken, or even fuse together.

A Perfect Trap for Light
At TU Wien (Vienna) and The Hebrew University of Jerusalem, a "light trap" was developed in which a beam of light prevents itself from escaping. This allows light to be absorbed perfectly. Whether in photosynthesis or in a photovoltaic system: if you want to use light efficiently, you have to absorb it as completely as possible.
