New method for using spin waves in magnetic materials
Smaller, faster, more energy-efficient - this is the goal that developers of electronic devices have been working towards for years. In order to be able to miniaturize individual components of mobile phones or computers for example, magnetic waves are currently regarded as promising alternatives to conventional data transmission functioning by means of electric currents.

Novel approach to non-uniform superconductivity
Superconductivity has fascinated scientists for many years both for fundamental reasons and because it offers the potential to revolutionize current technologies. Materials only become superconductors - meaning that electrons can travel in them with no resistance - at very low temperatures. These days, this unique zero resistance superconductivity is commonly found in a number of technologies, such as magnetic resonance imaging (MRI).

New synthesis approach for soluble silicon clusters
Theoretical calculations indicate that under certain conditions silicon can endow solar cells with a much higher efficiency. Small silicon clusters may provide a source of accordingly modified silicon. However, to date these clusters have not been accessible in soluble form, a prerequisite for flexible processing.

Münster University chemists create new types of Lewis acids
Researchers at the University of Münster have developed a method which makes it possible to create three-coordinate Lewis superacids on the basis of phosphorus. Previously, it had not been possible to isolate this type of compound, either in a liquid or in a solid state, due to its extreme electrophilicity and the associated reactivity.

Physicists couple key components of quantum technologies
Quantum effects are genuinely found in the world of nanostructures and allow a wide variety of new technological applications. For example, a quantum computer could in the future solve problems, which conventional computers need a lot of time to handle. All over the world, researchers are engaged in intensive work on the individual components of quantum technologies - these include circuits that process information using single photons instead of electricity, as well as light sources producing such individual quanta of light.

More accurate than expected
Despite their extremely small mass, neutrinos play a key role in cosmology and particle physics. After evaluation of the first measurement results in the Karlsruhe Tritium Neutrino Experiment (KATRIN), it is now clear: The previously unknown mass of the neutrinos must be less than 1 electron volt. This result is more accurate than previous measurements and raises hopes of discovering new neutrino properties.

New results for the mass of neutrinos
Apart from photons, the fundamental quanta of light, neutrinos are the most abundant elementary particles in the universe. As they possess a small non-zero mass, these "light-weights of the universe" play a key role in cosmology and particle physics. The most precise scale for neutrinos in the world is the international experiment "KATRIN" at the Karlsruhe Institute of Technology, in which scientists of the University of Münster are also involved.

Physicists from Stuttgart prove the existence of a supersolid state of matter
A supersolid is a state of matter that can be described in simplified terms as being solid and liquid at the same time. In recent years, extensive efforts have been devoted to the detection of this exotic quantum matter. A research team led by Tilman Pfau and Tim Langen at the 5th Institute of Physics of the University of Stuttgart has succeeded in proving experimentally that the long-sought supersolid state of matter exists.

Closing in on elusive particles
In the quest to prove that matter can be produced without antimatter, the GERDA experiment at the Gran Sasso Underground Laboratory is looking for signs of neutrinoless double beta decay. The experiment has the greatest sensitivity worldwide for detecting the decay in question. To further improve the chances of success, a follow-up project, LEGEND, uses an even more refined decay experiment.

New biosensor provides insight into the stress behaviour of plants
They are tiny signalling molecules that play important roles in many processes in living organisms. However, the exact function of these substances is often still unknown, which is why scientists are constantly on the lookout for new methods with which they can further investigate them. Researchers at the Universities of Münster and Nanjing (China) have developed such a method for an important messenger substance in plants, called phosphatidic acid.
