New Ways to Fine Tune Electrochemistry
New Ways to Fine Tune Electrochemistry
Scientists have found new paths to steer and optimize electrochemical processes. Optimizing electrochemical reactions is essential for the transition to renewable energies. In electrochemical reactions, electric currents and potential differences are used to binding and induce reactions. Electrochemistry is a pre-requisite for hydrogen production, and for batterie technology, and thus for sustainable chemistry.

Stronger than Nature: Optimised Radicals as Potential Novel Catalysts
Research team redesigns phenoxyl radicals with improved oxidation capacity in the lab. Nature uses enzymes for various metabolic processes. These biological catalysts are extremely efficient. Biomimetic catalysts based on inexpensive starting materials from the laboratory that can reproduce the efficiency of the natural enzymes and can function at ambient conditions are therefore of great interest to research and industry.

Turning One into Eight
Turning One into Eight
University of Bonn chemists invent technique for producing variants of natural substances To synthesize potential drugs or natural products, you need natural substances in specific mirror-image variants and with a high degree of purity. For the first time, chemists at the University of Bonn have succeeded in producing all'eight possible variants of polypropionate building blocks from a single starting material in a relatively straightforward process.

Surprisingly vibrant colour of 12-million-year-old snail shells
Surprisingly vibrant colour of 12-million-year-old snail shells
Researchers provide world's first evidence of intact polyene pigments in fossils Snail shells are often colourful and strikingly patterned. This is due to pigments that are produced in special cells of the snail and stored in the shell in varying concentrations. Fossil shells, on the other hand, are usually pale and inconspicuous because the pigments are very sensitive and have already decomposed.
