Microscaffolds: A new strategy in tissue engineering

Until now, there have been two completely different approaches to producing artificial tissue. At TU Wien, a third approach has now been developed that combines the advantages of both.

Exploring monoatomic platinum catalysts

What happens when a cat climbs onto a sunflower? The sunflower is unstable, will quickly bend, and the cat will fall to the ground. However, if the cat only needs a quick boost to catch a bird from there, then the sunflower ...

Quantum physics sets a speed limit to electronics

How fast can electronics be? When computer chips work with ever shorter signals and time intervals, at some point they come up against physical limits. The quantum-mechanical processes that enable the generation of electric ...

Topology can play a crucial role in the generation of laser light

A donut is not a bun. From a mathematical point of view, they are two fundamentally different objects: The donut has a hole, the bun does not. A circle inside the donut around its hole in the center cannot be shrunk to a ...

Record-breaking chemical reactivity with nanometer-scale sponge

Catalysts are often solid materials whose surface comes into contact with gases or liquids, thereby enabling certain chemical reactions. However, this means that any atoms of the catalyst that are not on the surface serve ...

2D material in three dimensions

The carbon material graphene has no well-defined thickness; it merely consists of one single layer of atoms. It is therefore often referred to as a "two-dimensional material." Trying to make a three-dimensional structure ...

Studying the big bang with artificial intelligence

It could hardly be more complicated: tiny particles whir around wildly with extremely high energy, countless interactions occur in the tangled mess of quantum particles, and this results in a state of matter known as "quark-gluon ...

Science fiction revisited: Ramjet propulsion

In science fiction stories about contact with extraterrestrial civilisations, there is a problem: What kind of propulsion system could make it possible to bridge the enormous distances between the stars? It cannot be done ...

Daylight causes road damage

The durability of asphalt depends crucially on bitumen—the black binder that holds the small stones in the asphalt together. As the bitumen ages, it can change its properties and become brittle, eventually causing the asphalt ...

Researchers develop nanometer-scale adaptive transistor

Normally, computer chips consist of electronic components that always do the same thing. In the future, however, more flexibility will be possible: New types of adaptive transistors can be switched in a flash, so that they ...
