The puzzle of the 'lost' angular momentum

In a closed physical system, the sum of all angular momentum remains constant, according to an important physical law of conservation. Angular momentum does not necessarily need to involve "real" bodily rotation in this context: ...

Binary mesocrystals from the nano-building kit

Mesocrystals are a class of solids formed by the regular arrangement of nanocrystals, which are tiny nanoparticles that have unique properties due to their small size. In mesocrystals, these take on a highly organized, superordinate ...

Global loss of floristic uniqueness due to spread of alien plants

When alien plants integrate into an existing ecosystem and successfully spread, in rare cases, it can contribute to the increased uniqueness of the regional flora. However, much more often, this process—known as naturalization—leads ...

Laser light used to modulate free electrons into qubits

The laws of quantum physics are not only extraordinary—they also offer some far-reaching and unique possibilities for advanced information processing, quantum computing and cryptography. So far, the basic building blocks ...

Making plastic durable and degradable

Polyethylene is the most abundantly manufactured plastic in the world. Due to properties like durability, it has many diverse, and even long-term uses. Professor Stefan Mecking's team in the Department of Chemistry at the ...

Genetic changes can affect collective behavior

Individual zebrafish (Danio rerio) exhibit predictable behavioral responses to certain visual stimuli that are sufficient to explain the collective behavior of the animals—even in their larval stage. Genetic mutations associated ...

New type of magnetism unveiled in an iconic material

Since the discovery of superconductivity in Sr2RuO4 in 1994, hundreds of studies have been published on this compound, which have suggested that Sr2RuO4 is a very special system with unique properties. These properties make ...

Light-induced shape shifting of MXenes

Ultrafast laser spectroscopy allows to observe the motion of atoms at their natural time scales in the range of femtoseconds, the millionth of a billionth of a second. Electron microscopy, on the other hand, provides atomic ...
