In the focus of X-rays: New materials for the energy transition

New Process to Test Materials for the Hydrogen Industry

27-Jun-2024 - Researchers at the Deutsches Elektronen-Synchrotron DESY have developed a method to rapidly test new materials for the hydrogen industry and analyze their properties down to the atomic level. They were the first to test so-called high-entropy alloys for their corrosion resistance to hydrogen, and ...

X-rays reveal how glasses lose their stability

PETRA III experiment shows how atoms in glass behave as weaknesses appear

28-Nov-2023 - Is glass solid or liquid? There is a popular misconception that old glass, which is often thicker at the bottom than at the top (such as stained-glass windows from cathedrals), flows downwards over time because it is actually an extremely viscous liquid. To a certain extent, this is true, glass ...

New insights about our Earth’s lower mantle

Scientists X-ray the most abundant mineral of Earth

21-Jul-2016 - Using DESY's bright X-ray light source PETRA III, a team of scientists has discovered unexpected facts about the most abundant mineral on Earth. The mineral bridgmanite makes up roughly one third of Earth’s entire volume and is the major component of Earth’s lower mantle. Thus, its physical ...

Crossing light with matter

Precision spectroscopy of X-ray polaritons

09-May-2016 - When light interacts with matter, it may be deflected or absorbed, resulting in the excitation of atoms and molecules; but the interaction can also produce composite states of light and matter which are neither one thing nor the other, and therefore have a name of their own – polaritons. These ...
