Catalyzing ammonia formation at lower temperatures with ruthenium

Nitrogen is an essential nutrient for plant growth. While about 80% of earth is nitrogen, it is mostly contained in the atmosphere as gas, and hence, inaccessible to plants. To boost plant growth, especially in agricultural ...

Radioactive cloud over Europe had civilian background

A mysterious cloud containing radioactive ruthenium-106, which moved across Europe in autumn 2017, is still bothering Europe's radiation protection entities. Although the activity concentrations were innocuous, they reached ...

Hotel Ruthenium: how hydrogen checks in but never leaves

How does hydrogen form blisters in ruthenium mirrors for extreme UV (EUV) lithography machines? An M2i research project by Chidozie Onwudinanti and colleagues at DIFFER, Eindhoven University of Technology and University of ...

Researchers observe metal to metal oxide progression

A catalyst's utility is influenced by its surface charge and how that charge is transferred. Until recently, studying charge transfer has relied on complex imaging techniques that are both expensive and time-consuming. Scientists ...

Charge transfer within transition-metal dyes analysed

Transition-metal complexes in dye-based solar cells are responsible for converting light into electrical energy. A model of spatial charge separation within the molecule has been used to describe this conversion. However, ...

From foe to friend: Graphene catalyzes the C-C bond formation

Graphene monolayers can be epitaxially grown on many single-crystal metal surfaces under ultra-high vacuum. On one side, these monolayers protect highly reactive metallic surfaces from contaminants, but on the other side, ...
