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.
With the X-ray laser SwissFEL, researchers at PSI want to produce movies of biomolecules in action. This can reveal how our eyes function or how new drugs work.
Researchers from the Paul Scherrer Institute PSI, the University of Basel and Roche have used neutron imaging to investigate why cool storage is crucial for syringes pre-filled with a liquid medication.
Physics isn't everyone's favourite subject. At the iLab of the Paul Scherrer Institute, students experience the material in a different way: with experiments instead of memorising formulas.
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.
The 16th of May is the International Day of Light. The research carried out with light at PSI enables advances in biology and pharmacology and also promotes the development of new materials for data storage and new technologies for personalised medicine.
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.
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.
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.
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.
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.
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.
The Zurich-based power company Energie 360° provides natural gas, biogas, and wood pellets throughout Switzerland. Now, with the Paul Scherrer Institute PSI, it has successfully tested a new Power-to-Gas technology to be implemented in the area of biogas production. The joint project was awarded the Swiss energy prize Watt d'Or 2018. In this interview, division manager Peter Dietiker talks about the collaboration with PSI.
At the Paul Scherrer Institute PSI, researchers are looking for solutions that enable energy from the sun, the wind, or biomass to be efficiently integrated into the Swiss energy system.
Efficiently producing energy from biowaste: A technology developed at PSI and tested in collaboration with the Zurich-based energy provider Energie 360° makes it possible. It extracts significantly more methane from biowaste than conventional methods. For this important contribution to a sustainable energy supply, PSI and Energie 360° have now been awarded the Watt d'Or 2018 in the Renewable Energy category by the Swiss Federal Office of Energy.
