Braids of Nanovortices Discovered

“These types of structures inside magnetic solids suggest unique electrical and magnetic properties"

06-Oct-2021

A team of scientists from Germany, Sweden and China has discovered a new physical phenomenon: complex braided structures made of tiny magnetic vortices known as skyrmions. Skyrmions were first detected experimentally a little over a decade ago and have since been the subject of numerous studies, ...

A unique scanning tunnelling microscope with magnetic cooling to study quantum effects developed

"Adiabatic cooling is a real quantum leap for scanning tunneling microscopy"

02-Sep-2021

Scanning tunnelling microscopes capture images of materials with atomic precision and can be used to manipulate individual molecules or atoms. Researchers have been using the instruments for many years to explore the world of nanoscopic phenomena. A new approach by physicists at Forschungszentrum ...

Infrared Detector for Smartphones and Autonomous Vehicles

Switching between different wavelengths

19-Aug-2021

Jülich researchers, together with Italian and German colleagues, have developed a particularly cost-effective infrared detector that can be easily integrated into existing camera chips and smartphones. The new sensor can make two technically important ranges of infrared radiation visible, which ...

Mechanism Deciphered: How Organic Acids Are Formed in the Atmosphere

17-May-2021

The acidity of the atmosphere is increasingly determined by carbon dioxide and organic acids such as formic acid. The second of these contribute to the formation of aerosol particles as a precursor of raindrops and therefore impact the growth of clouds and pH of rainwater. In previous atmospheric ...

Transparent nanolayers for more solar power

Nanostructured material and a new cell design pave the way for the production of silicon solar cells with more than 26 percent efficiency

20-Apr-2021

There is no cheaper way to generate electricity today than with the sun. Power plants are currently being built in sunny locations that will supply solar electricity for less than two cents per kilowatt hour. Solar cells available on the market based on crystalline silicon make this possible with ...

Ultrafast Electron Dynamics in Space and Time

"We believe that our findings represent a crucial breakthrough towards the goal of tracing electrons through chemical reactions in space and time"

22-Feb-2021

In textbooks and explanatory videos, they are often depicted as colourful balloons or clouds: electron orbitals provide information on the whereabouts of electrons in molecules, a bit like fuzzy snapshots. In order to understand the exchange of electrons in chemical reactions, it is not only ...

Increasing the Activity of Catalysts

A key to producing green hydrogen more efficiently

13-Jan-2021

A layer as thin as a single atom makes a huge difference: On the surface of an electrode, it doubles the amount of water split in an electrolysis system without increasing the energy requirements. Thus, the ultrathin layer also doubles the amount of hydrogen produced without increasing costs. ...

Oxide tuning by ion transfer

Researchers discover new formula for changing the electronic and magnetic properties of oxide interfaces

21-Dec-2020

Most materials are either magnetic, or they are not. However, scientists at Forschungszentrum Jülich have now discovered a new mechanism that allows for tailoring the electronic and magnetic properties of a material in a targeted and reversible manner. The effect depends on the transfer of ions ...

Autonomous Robot Plays with NanoLEGO

Scientists are developing an autonomous artificial intelligence system that can selectively grip and move individual molecules

07-Sep-2020

Molecules are the building blocks of everyday life. Many materials are composed of them, a little like a LEGO model consists of a multitude of different bricks. But while individual LEGO bricks can be simply shifted or removed, this is not so easy in the nanoworld. Atoms and molecules behave in a ...

Magnetic nanoparticles change their magnetic structure in a magnetic field

International research team studies the effects of magnetic fields on magnetic nanoparticles

28-Jul-2020

When ultrafine magnetic particles are exposed to an external magnetic field, their magnetic core grows in a previously unexpected way. This was observed by a team of scientists from the University of Cologne (UoC), Forschungszentrum Jülich and the Institut Laue-Langevin in Grenoble, France, by ...
