It sounds a bit like a magic trick
29-Nov-2022
When charged particles are being shot through ultra-thin layers of material, sometimes spectacular micro-explosions occur, sometimes the material remains almost intact. This has now been explained at the TU Wien. It sounds a bit like a magic trick: Some materials can be shot through with fast, ...
What determines the durability of high-performance coatings? Surprising results show: It is not material fatigue
18-Nov-2022
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. Coating processes play a role for large turbine blades as well as for extremely stressed tools in production ...
10-Nov-2022
TU Wien (Vienna) has succeeded in making a new type of material usable for chip technology. This enables faster, more efficient computers and new types of quantum devices. Our current chip technology is largely based on silicon. Only in very special components a small amount of germanium is ...
Worldwide search for exciting applications
11-Oct-2022
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 ...
Information is obtained that none of the methods alone could reveal
30-Sep-2022
One has to look very closely to exactly understand what processes take place on the surfaces of catalysts. Solid catalysts are often finely structured materials made of tiny crystals. There are various microscopies to monitor chemical processes on such surfaces – they use, for example, ...
"All indications are that we have found a robust way to identify materials that have the features we want"
22-Sep-2022
A new design principle can now predict the properties of quantum materials that have hardly been explored so far. For the first time, a strongly correlated topological semimetal has been discovered using a computer. How do you find novel materials with very specific properties - for example, ...
Novel perovskite catalysts could be used wherever methane and carbon dioxide are produced simultaneously
05-Sep-2022
CO2 and methane can be turned into valuable products. But until now the catalysts required for such reactions quickly lose their effectiveness. TU Wien has now developed more stable alternatives. Wherever the production of harmful greenhouse gases cannot be prevented, they should be converted ...
A fingertip-sized chip replaces bulky laboratory equipment: The possible applications are extremely diverse
01-Sep-2022
An infrared sensor has been developed at TU Wien (Vienna) that analyses the content of liquids within the fraction of a second. In analytical chemistry, it is often necessary to accurately monitor the concentration change of certain substances in liquids on a time scale of seconds. Especially in ...
Femtosecond journey through graphene
23-Aug-2022
When ions penetrate a material, highly complex processes take place - so fast that they could hardly be analyzed until now. But sophisticated measurements have now made it possible. How do different materials react to the impact of ions? This is a question that plays an important role in many ...
Using light, atoms can be made to attract each other
04-Aug-2022
A very special bonding state between atoms has been created in the laboratory for the first time: With a laser beam, atoms can be polarised so that they are positively charged on one side and negatively charged on the other. This makes them attract each other creating a very special bonding ...
