How catalysts remove dangerous nitrogen oxides

”If we know exactly where the reaction takes place, the production of catalysts can be controlled accordingly”

11-Oct-2024 - Catalysts belonging to the zeolite family help to remove toxic nitrogen oxides from industrial emissions. Researchers at the Paul Scherrer Institute PSI have now discovered that their complex nano porous structure is crucial. Specifically, individual iron atoms sitting in certain neighbouring ...

Climate-neutral air travel: Is it possible?

Climate-friendly fuel alone does not achieve the goal – but it helps

10-Jul-2023 - Researchers at the Paul Scherrer Institute PSI and ETH Zurich have performed calculations to work out how air traffic could become climate-neutral by 2050. They conclude that simply replacing fossil aviation fuel with sustainable synthetic fuels will not be enough. Air traffic would also have to ...

How football-shaped molecules occur in the universe

Solving the puzzle of classic buckyballs

30-Mar-2023 - For a long time it has been suspected that fullerene and its derivatives could form naturally in the universe. These are large carbon molecules shaped like a football, salad bowl or nanotube. An international team of researchers using the Swiss SLS synchrotron light source at PSI has shown how ...

A greener alternative for aviation fuel

PSI and Swiss start-up company launch pilot plant for synthetic kerosene

20-Feb-2023 - The Paul Scherrer Institute PSI and the Swiss start-up Metafuels are developing a new process for producing sustainable aviation fuel (SAF). They are now collaborating on the construction and operation of the first pilot plant on the PSI campus to validate the technology and prepare it for ...

Nanomaterial from the Middle Ages

Unlocking the secrets of Zwischgold

12-Oct-2022 - To gild sculptures in the late Middle Ages, artists often applied ultra-thin gold foil supported by a silver base layer. For the first time, scientists at the Paul Scherrer Institute PSI have managed to produce nanoscale 3D images of this material, known as Zwischgold. The pictures show this was ...

Making it easier to differentiate mirror-image molecules

Researchers have shown that mirror-image substances – so-called enantiomers – can be better distinguished using helical X-ray light

06-Jul-2022 - Using a new method, scientists are better able to distinguish between mirror-image substances. This is important amongst others in drug development, because the two variants can cause completely different effects in the human body. Researchers from Paul Scherrer Institute PSI, EPF Lausanne ...

Light amplification accelerates chemical reactions in aerosols

Temporal sequence of photochemical reaction in individual aerosol particles observed with high resolution

21-Apr-2022 - Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to demonstrate and quantify this effect and recommend factoring it into future climate models. Liquid ...

A look into the magnetic future

Researchers at PSI and ETH Zurich have observed for the first time how tiny magnets in a special layout align themselves solely as a result of temperature changes

06-Apr-2022 - This view into processes that take place within so-​called artificial spin ice could play an important role in the development of novel high-​performance computers. When water freezes to form ice, the water molecules, with their hydrogen and oxygen atoms, arrange themselves in a complex ...
