- Tyre wear particles in the Rhine: How microplastics are changing river ecology
A study by researchers at the universities of Duisburg-Essen and Cologne shows for the first time how microplastics from tyre particles are changing the microbial world in the Rhine. For a period o... - New Dynamics Discovered in Heterogeneous Catalysis
Oxygen evolution is considered one of the most energy-intensive steps in water electrolysis and is therefore a key factor for more efficient green hydrogen production. Modelling of the reaction mec... - Ammonia production by selective nitrogen reduction reaction
Electrocatalytic reduction of dinitrogen is a promising route for sustainable production of ammonia, although the selectivity challenge of the competing nitrogen reduction and hydrogen evolution re... - Mystery solved: Symmetry of exotic crystals
Crystals are highly symmetrical, but quasicrystals lack important symmetry properties. These solids pose puzzles for physics. A research team from the Technion in Haifa, the University of Duisburg-... - Fighting chemical pollution: water purification using algae
Europe's water bodies are in poor condition: more than half of them are heavily polluted with chemicals. This is hardly surprising - every day, up to 70,000 different chemicals are used in Europe's...
- Oxygen and chlorine evolution without noble metals
They are highly selective and can be easily separated from the reaction mixture: single-atom catalysts combine the advantages of homogeneous and heterogeneous catalysis. Until now, their production... - Mechanism of Cobalt-Manganese Catalysts Deciphered
The energy carrier hydrogen can be obtained from water by electrolysis. This works particularly well with Cobalt spinel electrocatalysts containing manganese. However, it was unclear why. Conven... - New paths for artificial nanofactories
Artificial nanofactories are tiny workshops made from the body's own molecules that are precisely designed and built according to a blueprint. In the future, they could help to better identify dise...
- Why nickelates are superconducting
Superconductors can transmit electric current without loss over any distance and play an important role in quantum computers and medical imaging. A new promising materials class are the nickelates,...
- Safe and efficient transport of Hydrogen: energy in Iron and its Oxides
Transporting green-generated energy in form of iron: That is the vision of a project funded by the German Federal Ministry of Education and Research and coordinated by the University of Duisburg-Es... - Catalyst surface analysed at atomic resolution
Catalyst surfaces have rarely been imaged in such detail before. And yet, every single atom can play a decisive role in catalytic activity. A German-Chinese research team has visualised the three-d...
- Predicting the Performance of Catalysts
Green electricity should be available as soon as possible, at best from all power outlets: electrochemical processes are the basis for a sustainable energy, but they need new, high-performance cata...
- Potential Beginning of Life Simulated in Lab
Did life originate not on the ground but underground? Scientists at the University of Duisburg-Essen (UDE) have substantiated their theory that first life could have begun deep in the earth's crust... - A new way to fine-tune exotic materials: Thin, stretch and clamp
One way to change the properties of a material is to stretch it just a wee bit, so its atoms are farther apart but the bonds between them don't break. This extra distance affects the behavior of el...
- Self-organizing molecules - nanorings with two sides
The tiny rings that chemists at the Center for Nanointegration (CENIDE) at the UDE create in the laboratory are as small as a bacterium. Self-organized, individual polymer chains form the flexible ... - Catalysis: High reaction rates even without precious metals
Precious metals are often efficient catalysts. But they are expensive and rare. However, it has so far been difficult to determine how efficient non-precious metal alternatives are. Non-precious... - Carbon nanoelectrode - Particle at the stick
Since they are so tiny, it is difficult to investigate single nanoparticles. However, this is exactly what researchers are aiming for in order to tailor their properties. A novel approach: particle...
