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 ...

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 ...

Novel X-ray lens facilitates glimpse into the nanoworld

Together with spin-off XRnanotech, PSI plans to market the new lens

16-Mar-2022 - PSI scientists have developed a ground-breaking achromatic lens for X-rays. This allows the X-ray beams to be accurately focused on a single point even if they have different wavelengths. The new lens will make it much easier to study nanostructures using X-rays, according to a paper just ...
