Electrified water drops

Electrostatic influences the movement of drops on surfaces

20-Apr-2022 - Something as simple as the motion of water drops on surfaces should actually be understood - one would think. In fact there are still numerous unanswered questions about the forces acting on a sliding droplet. A team of researchers from the Max Planck Institute for Polymer Research in ...

Deeper insight thanks to neutrons from a laser source

The desire to make the hidden visible has always been a driving force of research

28-Mar-2022 - A team led by the Technical University of Darmstadt has for the first time made laser-generated neutrons usable for an industrial application. The researchers showed that neutrons generated compactly with lasers can be used in non-destructive material testing. As electrically neutral particles, ...

Why some bubbles move faster

Why do large gas bubbles in viscoelastic liquids rise so much faster than expected?

07-Mar-2022 - An open question with great relevance for industrial production processes. Researchers at TU Graz and TU Darmstadt have now found an explanation. It is a puzzle long known among experts and very relevant in many industrial production processes: a jump discontinuity in the rise velocity of gas ...

Protons are probably actually smaller than long thought

Study suggests errors in the interpretation of older measurements

08-Feb-2022 - A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. This surprised the scientific community; some researchers even believed that the Standard Model of particle physics would have to be changed. Physicists at the University ...

New US and German collaboration aims to produce green hydrogen more efficiently

NSF-DFG EChem Award Announcement

27-Jul-2021 - Through a new award program, the U.S. National Science Foundation and the Deutsche Forschungsgemeinschaft (German Research Foundation, DFG) have joined forces to award the University of Illinois Urbana-Champaign and Technical University of Darmstadt a three-year $720,000 research grant ($500,000 ...

Mechanically imprinting atoms in ceramic

01-Jun-2021 - Electroceramics such as capacitors are essential components in electronic devices. Intervening in their crystalline structure can change specific properties. Thus, for instance, chemical methods can be used to replace individual atoms in the crystal lattice with others. A stable shape can be ...

Transparent view of atomic building blocks through inverse kinematics

31-Mar-2021 - Using inverse kinematics, the elegant inversion of an established research method, and choosing the right measurement conditions, an international team presented a way to study in detail the properties of the nucleon-nucleon interaction in the atomic nucleus. The experiment was carried out by a ...
