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.

The baritone of Red Giants refines cosmic distance measurements
A fresh look at red giant stars offers key insights into cosmic distance measurements and a way to measure the Universe's expansion with the highest accuracy. In a constantly expanding universe, measuring cosmic distances is like trying to find a reliable ruler in a vast, ever-stretching fabric. One tool that astrophysicists use is the Hubble constant, (H0), which measures how fast the Universe is expanding and sets the age and observable size of the Universe.

A new ion trap for larger quantum computers
A new ion trap for larger quantum computers
Researchers at ETH have managed to trap ions using static electric and magnetic fields and to perform quantum operations on them. In the future such traps could be used to realize quantum computers with far more quantum bits than have been possible up to now. The energy states of electrons in an atom follow the laws of quantum mechanics: they are not continuously distributed but restricted to certain well-defined values - this is also called quantisation.

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.
