Material from PSI helps to check inconsistencies in the Big Bang theory

Media Releases Research Using Neutrons Matter and Material Particle Physics

Shortly after the Big Bang, radioactive Beryllium-7 atoms were formed, which today, throughout the universe, they have long since decayed. A sample of beryllium-7 artificially produced at PSI has now helped researchers to better understand the first minutes of the universe.

On the path to new high-performance transistors

Media Releases Research Using Synchrotron Light Large Research Facilities Materials Research

The electronics industry expects a novel high-performance transistor made of gallium nitride to offer considerable advantages over present-day high-frequency transistors. Yet many fundamental properties of the material remain unknown. Now, for the first time, researchers at the Paul Scherrer Institute PSI have observed electrons while they were flowing in this promising transistor. For that they used one of the world's best sources of soft X-rays at PSI's Swiss Light Source SLS.

Cleaner emissions thanks to sponge-like structure

Media Releases Energy and Environment

PSI researchers have developed a new catalytic converter for cleaning emissions from natural gas engines. It is very active even at low temperatures and remains that way over a long period of time. This allows natural gas to be burned in a cleaner, more climate-friendly way. Thus natural gas and biogas become more attractive as substitutes for petroleum products – for example, as fuel for cars.

SwissFEL Storage Large Research Facilities

Data storage devices based on novel materials are expected to make it possible to record information in a smaller space, at higher speed, and with greater energy efficiency than ever before. Movies shot with the X-ray laser show what happens inside potential new storage media, as well as how the processes by which the material switches between two states can be optimised.

Biological light sensor filmed in action

Media Releases Biology SwissFEL

Using X-ray laser technology, a team led by researchers of the Paul Scherrer Institute PSI has recorded one of the fastest processes in biology. In doing so, they produced a molecular movie that reveals how the light sensor retinal is activated in a protein molecule. Such reactions occur in numerous organisms. The movie shows for the first time how a protein efficiently controls the reaction of the embedded light sensor.

Investigation into violation of research integrity is concluded


Last summer a violation of research integrity was reported to the Paul Scherrer Insitute PSI. The results of the investigation are now available. PSI has taken several measures as a consequence.

Opening: Advanced technology against cancer

Media Releases Medical Science Human Health Proton Therapy

With proton therapy, certain tumours can be irradiated with exceptional precision – while, the surrounding healthy tissue is optimally protected. In Switzerland, this kind of radiation therapy is only possible at PSI. In a joint project with the University Hospital Zurich and the University of Zurich, PSI has expanded its capacity with a state-of-the-art treatment facility: the new, 270-ton Gantry 3.

Cleaner diesel emissions

Media Releases Energy and Environment Research Using Synchrotron Light

PSI researchers have found out why it is harder to control the noxious nitrogen oxides in diesel exhaust at low temperatures – and how, in the future, emissions can be cleaned more efficiently depending on the temperature.

Power on demand

Energy and Environment Storage Renewable Energies ESI Platform

If photovoltaic or wind power plants produce more electricity than the network can absorb, valuable energy is lost. At the ESI Platform, PSI researchers are investigating how fuel cells can contribute to making this energy usable in a targeted way through storage.

Lausanne-Villigen return

Human Health Matter and Material Proton Therapy

Nowhere in the world have so many ocular tumours been irradiated with protons as at PSI. But before the affected patients go to Villigen, they have to visit Lausanne: for pretreatment at the Jules Gonin Ophthalmic Hospital. The more than 30-year-long collaboration between the hospital and PSI is unique, and in most cases it saves the patient's diseased eye.

Profitable for both sides

Energy and Environment Renewable Energies ESI Platform

The young company Swiss Hydrogen is located in Fribourg. Here work is under way on competitive high-performance fuel cells that could be used in environmentally friendly vehicles or deployed as stationary power generators. In the company's collaboration with PSI, as CEO Alexandre Closset explains in this interview, both sides profit.

Imaging at Paul Scherrer Intitute helps to increase production at ABB site in Aargau

Media Releases Research Using Neutrons Matter and Material Industrial co-operation

The ABB facility in Wettingen got practical recommendations on increasing production of ceramic components. Researchers at the Paul Scherrer Institute PSI examined the components by means of neutron imaging. With the help of these images, ABB employees were able to see where there is still potential for process optimisation. This feasibility study was funded by the Hightech Zentrum Aargau.
