Using light to produce medication and plastics more efficiently
Using light to produce medication and plastics more efficiently
Anyone who wants to produce medication, plastics or fertilizer using conventional methods needs heat for chemical reactions - but not so with photochemistry, where light provides the energy. The process to achieve the desired product also often takes fewer intermediate steps. Researchers from the University of Basel are now going one step further and are demonstrating how the energy efficiency of photochemical reactions can be increased tenfold.

Quest for materials with defects
Quest for materials with defects
Is it possible to convert CO2 back to fuels or other useful chemicals? Absolutely - but not in a very targeted way just yet. Empa researcher Alessandro Senocrate is looking at defects in materials that will help us achieve this goal. Can we undo the burning of oil, gas and coal? With a renewable source of electricity, some water and a suitable catalyst, the excess CO2 in the atmosphere could become a resource, for example for the production of synthetic fuels, so-called synfuels.

It's the spin that makes the difference
It’s the spin that makes the difference
Biomolecules such as amino acids and sugars occur in two mirror-image forms - in all living organisms, however, only one is ever found. Why this is the case is still unclear. Researchers at Empa and Forschungszentrum Jülich in Germany have now found evidence that the interplay between electric and magnetic fields could be at the origin of this phenomenon.
