Insulator makes electrons move in an ordered way

Media Releases Research Using Synchrotron Light Materials Research Matter and Material

Researchers at the PSI, the EPFL and the Chinese Academy of Science, have proven that the material SmB6 shows all the properties of a so called topological insulator – a material with electric currents flowing along its surface with all of them being polarized. Here, the property is very robust, i.e. the only current that can flow is spin polarized and is not easily destroyed by small irregularities in the structure or composition of the material. Spin polarized currents are necessary for spintronics, electronics using the electrons’ spin.

Ice in fuel cells imaged directly for the first time

Media Releases Energy and Environment Research Using Neutrons

Researchers from the Paul Scherrer Institute (PSI) have succeeded in imaging the distribution of frozen and liquid water in a hydrogen fuel cell directly for the first time. They applied a new imaging technique that uses successively two beams with different neutron energies to distinguish between areas with liquid water and those with ice extremely reliably. The method therefore opens up the prospect of studying one of the main problems of using fuel cells to power vehicles: ice can clog the pores in the fuel cells and affect their performance. The PSI scientists’ results will be published in the journal Physical Review Letters on 16 June 2014.

Sixteen nanometres in 3D

Media Releases Research Using Synchrotron Light

Researchers from the Paul Scherrer Institut (PSI) have devised a method that opens up new scales of tomographic imaging and will thus allow in the future highly resolved measurements of biological and materials science specimens. With the aid of a special prototype instrument at the Swiss Light Source (SLS), they achieved a 3D resolution of sixteen nanometres in a large sample and thus set a new world record in X-ray tomography.

New insight into photosynthesis

Media Releases Biology Research Using Neutrons Large Scale Facilities

The way that algae and plants respond to light has been reinterpreted based on results from recent experiments. Under particular lighting conditions during photosynthesis, the well-ordered stacking and alignment of light-sensitive membranes in the algae are disrupted. There is no significant movement of the membrane embedded light harvesting proteins, which rather become largely inactive. These new findings challenge widely accepted views of how algae respond to light where the light harvesting proteins were thought to move around the membranes.

Cloud formation takes ingredients from the forest

Media Releases Energy and Environment Environment

Scientists know that clouds have a net cooling effect on our planet but the exact magnitude of that cooling effect is not exactly known. A new study by the CLOUD experiment (Cosmics Leaving OUtdoor Droplets) at CERN sheds light on the very first step of cloud formation, thereby contributing to a better understanding of the cloud-climate connection. The study was led by scientists at the Paul Scherrer Institute (PSI) and was published on 16 May 2014 in the journal Science

Phase contrast improves mammography

Media Releases Medical Science Human Health

Phase contrast X-ray imaging has enabled researchers at ETH Zurich, the Paul Scherrer Institute (PSI) and the Kantonsspital Baden to perform mammographic imaging that allows greater precision in the assessment of breast cancer and its precursors. The technique could improve biopsy diagnostics and follow-up.

Unassuming rampant polluters on two wheels

In some towns small mopeds cause more air pollution than cars

Not cars or trucks, but mopeds with their two-stroke engines are the main source of fine particles and other air contaminants in many towns in Asia, Africa and southern Europe. This is revealed by the study of an international research team headed up by researchers at the Paul Scherrer Institute PSI. The reasons for the high emissions are the combustion properties in two-stroke engines and the overly lenient emission requirements for small two-wheelers. The study findings are to be published on 13 May 2014 in the journal Nature Communications.

Processes in stars recreated with isotopes from PSI
Isotopes that otherwise only naturally exist in exploding stars – supernovae – are formed at the Paul Scherrer Institute’s research facilities. This enables processes that take place inside the stars to be recreated in the lab. For instance, an international team of researchers used the titanium isotope Ti-44 to study one such process at CERN in Geneva. In doing so, it became evident that it is less effective than was previously believed and the previous theoretical calculations of processes in stars need to be corrected.

Quantum melting

Media Releases Research Using Neutrons Large Scale Facilities

Changes to the aggregate state triggered by quantum effects – in physically correct terms, quantum phase transitions – play a role in many astonishing phenomena in solids, such as high-temperature superconductivity. Researchers from Switzerland, Great Britain, France and China have now specifically altered the magnetic structure of the material TlCuCl3 by exposing it to external pressure and varying this pressure. With the aid of neutrons, they were able to observe what happens during a quantum phase transition, where the magnetic structure melts quantum-physically.

Fuel cell know-how from the Paul Scherrer Institute at the core of the SBB minibar

Media Releases Energy and Environment

On 4 April 2014 SBB is to launch a new minibar model in its Intercity trains. A fuel cell system including know-how of the Paul Scherrer Institute will also be on board. It will ensure that despite the limited space the minibar will have enough power to brew capuccinos and latte macchiatos, too.

X-rays film inside live flying insects – in 3D

Media Releases Biology Research Using Synchrotron Light User Experiments

Scientists have used a particle accelerator to obtain high-speed 3D X-ray visualizations of the flight muscles of flies. The team from Oxford University, Imperial College, and the Paul Scherrer Institute (PSI) developed a groundbreaking new CT scanning technique at the PSI’s Swiss Light Source to allow them to film inside live flying insects. The movies offer a glimpse into the inner workings of one of nature’s most complex mechanisms, showing that structural deformations are the key to understanding how a fly controls its wingbeat.

Media Releases Research Using Synchrotron Light Materials Research Matter and Material SwissFEL

Researchers from ETH Zurich and the Paul Scherrer Institute PSI demonstrate how the magnetic structure can be altered quickly in novel materials. The effect could be used in efficient hard drives of the future.

The proton accelerator at the Paul Scherrer Institute: forty years of top-flight research

Media Releases Large Scale Facilities Research Using Muons Research Using Neutrons Particle Physics Matter and Material

Materials research, particle physics, molecular biology, archaeology – for the last forty years, the Paul Scherrer Institute’s large-scale proton accelerator has made top-flight research possible in a number of different fields.
