19. November 2015Media Releases Biology Research Using Synchrotron Light Human Health
Bones are made up of tiny fibres that are roughly a thousand times finer than a human hair. Researchers at the Paul Scherrer Institute PSI have developed a new computer-based algorithm with which they were able to visualize the localised order and alignment of these nanostructures inside an entire piece of bone for the first time.
5. November 2015Media Releases Research Using Synchrotron Light Matter and Material
When bridges, dam walls and other structures made of concrete are streaked with dark cracks after a few decades, the culprit is the so-called the
concrete disease. Researchers from the Paul Scherrer Institute PSI and Empa have now solved the structure of the material produced in these cracks at atomic level - and have thereby discovered a previously unknown crystalline arrangement of the atoms.
26. October 2015Media Releases Matter and Material Materials Research SwissFEL
Researchers from the Paul Scherrer Institute PSI have succeeded in using commercially available camera technology to visualise terahertz light. In doing so, they are enabling a low-cost alternative to the procedure available to date, whilst simultaneously increasing the comparative image resolution by a factor of 25. The special properties of terahertz light make it potentially advantageous for many applications. At PSI, it will be used for the experiments on the X-ray free-electron laser SwissFEL.
2. October 2015Media Releases Research Using Neutrons Particle Physics
Our universe consists of significantly more matter than existing theories are able to explain. This is one of the great puzzles of modern science. One way to clarify this discrepancy is via the neutron’s so-called electric dipole moment. In an international collaboration, researchers at PSI have now devised a new method which will help determine this dipole moment more accurately than ever before.
23. September 2015Media Releases Energy and Environment Storage
Researchers from the Paul Scherrer Institute (PSI) have developed a coating technique in the laboratory conditions that could raise the efficiency of fuel cells. The PSI scientists have already applied to patent the technique, which is suitable for mass production.
21. September 2015Media Releases Materials Research Matter and Material Research Using Muons Micro- and Nanotechnology
Researchers at the Paul Scherrer Institute (PSI) created a synthetic material out of 1 billion tiny magnets. Astonishingly, it now appears that the magnetic properties of this so-called metamaterial change with the temperature, so that it can take on different states; just like water has a gaseous, liquid and a solid state.
8. September 2015Media Releases Energy and Environment Research Using Synchrotron Light
Lithium iron phosphate batteries are very durable and can be charged relatively quickly. Researchers from the Paul Scherrer Institute (PSI), ETH Zurich and Japanese car manufacturer Toyota reveal the reasons for these properties in a new study. The findings were made possible thanks to measurements using a new method at the Swiss Light Source (SLS) at PSI.
10. August 2015Media Releases Biology Human Health Medical Science
Researchers unveil new details of how cells in a living organism process stimuli. So-called G-proteins, which help conduct external stimuli that reach a cell into its interior, play a central role here. For the first time, the study shows which parts of the G-proteins are vital for their function. Researchers from the Paul Scherrer Institute PSI, ETH Zurich, the pharmaceutical company Roche and the British MRC Laboratory of Molecular Biology report their results in the journals Nature and Nature Structural and Molecular Biology.
6. August 2015Media Releases Materials Research Matter and Material Research Using Muons
For the first time, an international research team has demonstrated how to generate magnetism in metals that aren’t naturally magnetic, such as copper. The discovery could help develop novel magnets for a wide range of technical applications. Crucial measurements to understand this phenomenon were carried out at PSI – the only place where magnetic processes inside materials can be studied in sufficient detail.
29. June 2015Media Releases Environment Energy and Environment
For years, studies have proved that fine dust from petrol engines can damage our health. Modern engine technology does not help, either, as researchers from the University of Bern and the Paul Scherrer Institute (PSI) reveal.
20. March 2015Media Releases Matter and Material Research Using Synchrotron Light Micro- and Nanotechnology
Scientists at the Paul Scherrer Institute and ETH Zurich have created 3D images of tiny objects showing details down to 25 nanometres. In addition to the shape, the scientists determined how particular chemical elements were distributed in their sample and whether these elements were in a chemical compound or in their pure state.
6. March 2015Media Releases Environment
Until it was banned, leaded gasoline dominated the manmade lead emissions in South America
Leaded gasoline was a larger emission source of the toxic heavy metal lead than mining in South America – even though the extraction of metals from the region’s mines historically released huge quantities of lead into the environment. Researchers from the Paul Scherrer Institute PSI and the University of Bern have discovered evidence of the dominance of leaded gasoline based on measurements in an ice core from a Bolivian glacier. The scientists found that lead from road traffic in the neighbouring countries polluted the air twice as heavily as regional mining from the 1960s onwards. The study is to be published in the journal Science Advances on 6 March 2015.
19. January 2015Media Releases Matter and Material Materials Research Micro- and Nanotechnology
Germanium-Zinn-Halbleiterlaser lässt sich direkt auf Siliziumchips aufbringen
Winzige Laser, die in Computerchips aus Silizium eingebaut werden, sollen in Zukunft die Kommunikation innerhalb der Chips und zwischen verschiedenen Bauteilen eines Computers beschleunigen. Lange suchten Experten nach einem dafür geeigneten Lasermaterial, das sich mit dem Fertigungsprozess von Siliziumchips vereinbaren lässt. Wissenschaftler des Forschungszentrums Jülich und des Paul Scherrer Instituts PSI haben hier nun einen wichtigen Fortschritt erzielt.

12. January 2015Media Releases Matter and Material Research Using Synchrotron Light Materials Research
Researchers at the Paul Scherrer Institute (PSI) have succeeded in switching tiny, magnetic structures using laser light and tracking the change over time. In the process, a nanometre-sized area bizarrely reminiscent of the Batman logo appeared. The research results could render data storage on hard drives faster, more compact and more efficient.
