More than a prototype
Jean-Baptiste Mosset, winner of a Founder Fellowship at the Paul Scherrer Institute PSI, wants to commercialise a neutron detector to spot plutonium and uranium.
Driving into danger with the blue lights flashing
The PSI radiation protection service is responsible for missions not only at the Institute, but throughout the canton of Aargau. Four times a year the unit practises for an emergency.
PSI spin-off GratXray wins Swiss Technology Award 2017
A spin-off from PSI has received this year's Swiss Technology Award: The young company GratXray is developing a new method for early diagnosis of breast cancer.
Still no sign of dark matter
No evidence of dark matter made of axions – result of an experiment at the Paul Scherrer Institute PSI further constrains theories about the nature of dark matter.
A new bio-robot
With a new method for modifying antibodies, Philipp Spycher, winner of a Founder Fellowship at the Paul Scherrer Institute PSI, wants to develop drugs that are more stable and, thus, have fewer side-effects.
Stress test passed
With a technology developed at the Paul Scherrer Institute PSI, around 60 percent more biogas can be produced from bio-waste than with conventional methods. But can it stand the test in practice as well? A 1,000-hour test at the Werdhölzli biowaste digestion and wastewater treatment plant in Zurich was able to answer this question with a clear yes. It was carried out in cooperation with the Zurich-based energy provider Energie 360°. The analysis of the stress test is now available.
From golden emperor to filled Buddha
Ancient metal objects are illuminated by neutrons at the Paul Scherrer Institute PSI. This enables researchers to discover what is hidden inside them, how they were made and how they can be preserved.
Highlighting the significance of structural analysis of biomolecules
The Nobel Prize in Chemistry 2017 has been awarded to Jacques Dubochet of Switzerland, U.S.-based German scientist Joachim Frank, and Richard Henderson of the United Kingdom for the development of structural analysis of single biological molecules by means of cryo-electron microscopy. The awarding of the prize underscores the fundamental significance of structural analysis of biomolecules for modern biology – a research area where the Paul Scherrer Institute PSI plays a leading role in Switzerland.
Atmosphere in X-ray light
PSI researchers have developed an experimental chamber in which they can recreate atmospheric processes and probe them with unprecedented precision, using X-ray light from the Swiss Light Source SLS. In the initial experiments, they have studied the production of bromine, which plays an essential role in the decomposition of ozone in the lower layers of the atmosphere. In the future, the new experiment chamber will also be available for use by researchers from other scientific fields.
X-ray and neutron imaging for palaeontologists and archaeologists
Federica Marone illuminates objects with high-intensity X-ray beams, Eberhard Lehmann with neutrons. Both have used their methods to give palaeontologists and archaeologists a new view into the past.
The hard worker from Val Mesolcina
For Aldo Antognini, physics and conviviality are in the bloodPSI researcher Aldo Antognini has received more than 2.2 million Swiss francs from the EU for his latest experiment. He wants to find out how magnetism is distributed in the proton. The particle physicist will be able to apply not only his scientific and technical talents, but his social flair as well.
Custom-tailoring better metallic materials
Using the large research facilities at PSI, Helena Van Swygenhoven-Moens examines the inner workings of metals. The watch industry needs small, robust springs and engineers are interested in turbine blades made of stress resistant materials.
More than just spilling the beans
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 quality methane to be formed from spent coffee grounds. PSI researchers involved in a pilot project carried out in cooperation with the Swiss food producer Nestlé were able to show that spent coffee grounds left over during the production of instant coffee can be efficiently re-used elsewhere.
Testing the Limits for the Patients' Benefit
Proton therapy is already a success story at the Paul Scherrer Institute PSI but researchers remain dedicated to making treatment faster and safer.
Diving into magnets
For the first time, scientists have made visible the directions of the magnetisation inside a 3D magnetic object. The smallest details in their visualisation were ten thousand times smaller than a millimetre. Among others, the magnetic structure contained one outstanding kind of pattern: magnetic singularities called Bloch points, which up to now were only known in theory.
Nanomaterial helps store solar energy: efficiently and inexpensively
Efficient electrolysers are needed in order to store sun and wind energy in the form of hydrogen. Thanks to a new material developed by researchers at the Paul Scherrer Institute PSI and Empa, these devices are likely to become less costly and more efficient in the future. Researchers were also able to demonstrate that this new material can be reliably produced in large quantities, showing its performance capability in an electrolysis cell—the main component of an electrolyser.
Research experience from California benefits Swiss X-ray free-electron laser SwissFEL
An X-ray free-electron laser (XFEL) is capable of visualizing extremely fast structural and electronic processes. Pilot experiments will take place at the PSI's Swiss Free-Electron Laser (SwissFEL) from the end of 2017 on. Two current publications in Science and Nature Communications demonstrate the kind of outstanding scientific work that is enabled by such facilities. The work was carried out at the Linac Coherent Light Source (LCLS) in California. Two of the leading authors behind these studies have now relocated to the PSI in order to share their expertise as SwissFEL expands its capabilities.
Fuel and chemicals from plant waste
Lignin, as a constituent of many plants, accumulates in large quantities and could theoretically be used as a precursor material for production of fuels and chemicals. Researchers at the Paul Scherrer Institute PSI and ETH Zurich have developed a method with which the processes that take place in the catalytic breakdown of lignin can be observed in detail. The knowledge thus gained could enable targeted improvement of production methods in the future.
Injector 2: a pre-accelerator for protons
As fundamental building blocks of matter, protons are part of all the things that surround us. At the Paul Scherrer Institute PSI, though, they step out of their usual role and are deployed to generate other particles, namely neutrons and muons, which are then used to study materials. But for that, the protons first have to be accelerated. An important role in this is played by a three-stage accelerator facility, in the middle of which stands the accelerator known as Injector 2.
