Scientist discovers new oxidation state of rhodium

Mayara da Silva Santos, doctoral candidate at the University of Freiburg's Institute of Physics, has discovered a new oxidation state of rhodium. This chemical element is one of the most catalytically important platinum-group ...

Metabolically engineered bacterium produces lutein

Lutein is classified as a xanthophyll chemical that is abundant in egg yolk, fruits, and vegetables. It protects the eye from oxidative damage from radiation and reduces the risk of eye diseases including macular degeneration ...

How the first biomolecules could have been formed

The chemical precursors of present-day biomolecules could have formed not only in the deep sea at hydrothermal vents, but also in warm ponds on the Earth's surface. The chemical reactions that may have occurred in this "primordial ...

Decoding the lifecycle of photogenerated charges

New materials will enable novel technologies to turn sunlight into electricity and fuels. Combinations of molecules and tiny nanoparticles make these materials a reality. The molecules in these materials are very good at ...

Catalyst material exhibits baffling surface state

Sometimes chemical reactions in the lab work the way you imagine them to, and sometimes they don't. Neither is unusual. What is highly unusual, however, is what a research team at TU Wien has now observed when studying hydrogen ...
