Atom-Billiards with X-Rays

A new Approach to look inside of Molecules

28-Sep-2020

In 1921, Albert Einstein received the Nobel Prize in physics for the discovery that light is quantized, interacting with matter as a stream of particles called photons. Since these early days of quantum mechanics, it is known that photons also possess momentum. The photon’s ability to transfer ...

The Return of the Spin Echo

Research team discovered a remarkable echo effect - it offers exciting new possibilities for working with quantum information

28-Sep-2020

Small particles can have an angular momentum that points in a certain direction - the spin. This spin can be manipulated by a magnetic field. This principle, for example, is the basic idea behind magnetic resonance imaging as used in hospitals. An international research team has now discovered a ...

Technological innovation: The smallest particle sensor in the world

Compact and energy-efficient sensor for mobile devices, informs in real time about the fine dust content in the air and warns in case of elevated values

25-Sep-2020

It is slightly smaller than two one-cent coins stacked on top of each other, is particularly energy-efficient due to its size, requires no maintenance and can be integrated in mobile devices. It is the smallest particle sensor in the world. With this 12 x 9 x 3 millimetre innovation, smartphones, ...

How charges move in solar cells

An understanding of microscopic processes in perovskite solar cells can lead to increased efficiency

22-Sep-2020

When the sun rises, a complex dance begins in perovskite solar cells - a type of solar cell that can supplement or replace existing silicon solar cells in the future: Electrons are supplied with energy by light and move. Where electrons move, they leave holes. At the same time, ions move around ...
