How catalysts age

"Our new, detailed results could help industrial companies optimise their catalysts and make them more durable"

11-Jun-2021

PSI researchers have developed a new tomography method with which they can measure chemical properties inside catalyst materials in 3D extremely precisely and faster than before. The application is equally important for science and industry. The material group of vanadium phosphorus oxides (VPOs) ...

Uniquely sharp X-ray view

For the first time, it is possible to look inside materials with a resolution down to individual atoms

26-Apr-2021

Researchers at the Paul Scherrer Institute PSI have succeeded for the first time in looking inside materials using the method of transient grating spectroscopy with ultrafast X-rays at SwissFEL. The experiment at PSI is a milestone in observing processes in the world of atoms. The structures on ...

Particulates are more dangerous than previously thought

Harmful substances are already formed in the atmosphere, not just in the human body

24-Mar-2021

Researchers at the Paul Scherrer Institute PSI have for the first time observed photochemical processes inside the smallest particles in the air. In doing so, they discovered that additional oxygen radicals that can be harmful to human health are formed in these aerosols under everyday ...

Nanostructures with a unique property

For the first time, researchers have managed to create and identify antiferromagnetic skyrmions with a unique property

25-Sep-2020

Nanoscale vortices known as skyrmions can be created in many magnetic materials. For the first time, researchers at PSI have managed to create and identify antiferromagnetic skyrmions with a unique property: critical elements inside them are arranged in opposing directions. Scientists have ...

Better catalysts for a sustainable bioeconomy

Get zeolite research out of the dead end

24-Sep-2020

Researchers at the Paul Scherrer Institute PSI and from ETH Zurich want to make so-called zeolites more efficient. Today, these compounds are already indispensable additives in the chemical industry and have been used as catalysts in oil refineries since the 1960s. Now, in the journal Nature ...

Lighting material of the future

Green luminescent substance is a hot candidate for producing OLEDs

07-May-2020

At the Paul Scherrer Institute PSI, researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). The substance enables high light yields and would be inexpensive to produce on a large scale - that means it is practically made for use in large-area room ...

Weyl fermions discovered in another class of materials

16-Jul-2019

A particular kind of elementary particle, the Weyl fermions, were first discovered a few years ago. Their specialty: They move through a material in a well ordered manner that practically never lets them collide with each other and is thus very energy efficient. This implies intriguing ...

Recycling carbon dioxide from the ocean

Floating power plants

11-Jun-2019

Paper, tin cans, glass - the world recycles as much as possible. So why not declare the greenhouse gas carbon dioxide (CO2) a recycling product as well? Liquid fuels based on carbon will continue to play an important role in the future - despite international efforts to reduce them. So it seems ...

A special phenomenon in magnets

A compass pointing West

02-Apr-2019

Researchers from the Paul Scherrer Institute PSI in Villigen and the ETH Zurich have discovered a special phenomenon in magnets. This phenomenon takes place at the nanoscale and enables magnets to be assembled in unusual configurations, which could also be useful for computer technology and data ...

More than just spilling the beans: High quality methane to be formed from spent coffee grounds

22-Aug-2017

Because of their high nitrogen content, spent coffee grounds are a popular garden fertilizer. Recycled in this manner, they already contribute to an environmentally friendly waste management. But they have the potential to deliver much more: a new procedure developed at the PSI allows high ...
