Start-up succeeds 3D-printing breakthrough – magic black(!) material allows photopolymerization

Combined with new translucent material, 3D-printing of entire optical systems possibl

13-Oct-2021

Highly precise 3D-structures in black can now be printed using a 2 Photon-Polymerization (2PP) 3D-printing process. This seemed for a long time impossible as non-transmissive (black) materials greatly reduce the polymerization efficiency of the printing process. Now the 2PP-specialist UpNano GmbH ...

A Sandblaster at the Atomic Level

21-Sep-2021

From semiconductors to moon rocks: Many materials are treated with ion beams. A research group at TU Wien has now been able to explain how this process depends on the roughness of the surface. If you want to remove a layer of paint from a metal surface, you can use a sandblaster: Countless grains ...

Eco-friendly process for synthesizing organic materials developed for high-performance materials industry

Green production with 25 percent initial cost savings

10-Sep-2021

Until now, the production of materials from organic substances was only possible with the use of highly toxic solvents. A team led by Uni Konstanz Prof. and CeMM Adjunct PI Miriam Unterlass has now developed a method for making organic substances suitable for use as high-performance materials in ...

Researchers find a way to check that quantum computers return accurate answers

08-Sep-2021

Quantum computers become ever more powerful, but how can we be sure that the answers they return are accurate? A team of physicists from Vienna, Innsbruck, Oxford, and Singapore solves this problem by letting quantum computers check each other. Quantum computers are advancing at a rapid pace and ...

Anchoring single atoms

How can single atoms be used for catalysis? Researchers develop a new method to anchor single atoms to supports

01-Sep-2021

There is a dictum to “never change a running system”. New methods can however be far superior to older ones. While to date chemical reactions are mainly accelerated by catalytic materials that comprise several hundreds of atoms, the use of single atoms could provide a new approach for ...

Supersolid in a new dimension

Two-dimensional supersolid quantum gas produced in the laboratory for the first time

20-Aug-2021

Quantum matter can be solid and fluid at the same time – a situation known as supersolidity. Researchers led by Francesca Ferlaino have now created for the first time this fascinating property along two dimensions. They now report in the journal Nature on the realization of supersolidity along ...

How ions get their electrons back

What happens when ions are passing through solid materials? It is nearly impossible to observe this directly, but scientists at TU Wien found a way to overcome this problem

17-Aug-2021

Very unusual atomic states are produced at TU Wien: Ions are created by removing not just one but 20 to 40 electrons from each atom. These “highly charged ions” play an important role in current research. For a long time, people have been investigating what happens when such highly charged ions ...

Modeling uncovers an "atomic waltz" for atom manipulation

16-Aug-2021

Researchers at the University of Vienna’s Faculty of Physics in collaboration with colleagues from the Oak Ridge National Laboratory in the USA have uncovered a non-destructive mechanism to manipulate donor impurities within silicon using focused electron irradiation. In this novel indirect ...

The factory of the future speaks our language

In the future, artificial intelligence will monitor and maintain industrial plants. To do this, however, it must be able to understand human texts – TU Wien shows how this can be done

11-Aug-2021

The complexity of large industrial production plants is hardly manageable for a single person. In order to maintain, monitor and service an industrial production line, it therefore makes sense to rely on artificial intelligence (AI). There are different strategies for this. The most obvious would ...

Cattle stomachs help break down plastic

04-Aug-2021

New results from a group of researchers at the Austrian Centre of Industrial Biotechnology (acib) and BOKU Vienna show that bacteria from cow stomachs can be used to degrade polyesters, which are used to make textiles, packaging and compostable plastic bags, among other things. On the one hand, ...
