How acidic are atoms?

The degree of acidity or alkalinity of a substance is crucial for its chemical behavior. The decisive factor is the so-called proton affinity, which indicates how easily an entity accepts or releases a single proton. While ...

New catalyst for lower carbon dioxide emissions

If the CO2 content of the atmosphere is not to increase any further, carbon dioxide must be converted into something else. However, as CO2 is a very stable molecule, this can only be done with the help of special catalysts. ...

2D nanomaterial MXene: The perfect lubricant for rovers

You can lubricate a bicycle chain with oil, but what do you do with a Mars rover or a red-hot conveyor belt in the steel industry? Very special nanomaterials have now been studied by the TU Wien together with research groups ...

3D-printed material to replace ivory for restoration of artifacts

For centuries, ivory was often used to make art objects. But to protect elephant populations, the ivory trade was banned internationally in 1989. To restore ivory parts of old art objects, one must therefore resort to substitute ...

Heat conduction record with tantalum nitride

A thermos bottle has the task of preserving the temperature—but sometimes you want to achieve the opposite: Computer chips generate heat that must be dissipated as quickly as possible so that the chip is not destroyed. ...

Moiré effect: How to twist material properties

2D materials have triggered a boom in materials research. Now it turns out that exciting effects occur when two such layered materials are stacked and slightly twisted.

Researchers produce beams of entangled atoms

Heads or tails? If we toss two coins into the air, the result of one coin toss has nothing to do with the result of the other. Coins are independent objects. In the world of quantum physics, things are different: Quantum ...
