“Airpocalypse” explained

Media Releases Environment Energy and Environment

The causes of China’s record level fine particulate pollution in winter 2013

At the beginning of 2013 a greyish-brown blanket of smog lay over large areas of China for several months. The fine particle pollution was higher by 1 to 2 orders of magnitude than the levels normally measured in Western Europe and the United States. An international team of researchers under the lead of the Paul Scherrer Institute PSI and the Institute of Earth Environment, Chinese Academy of the Sciences revealed the causes of the “airpocalypse”. The study published in the journal Nature also describes what steps are to be taken to prevent an environmental crisis of this kind in the future.

Energiewende in Reinkultur – in Wädenswil zu bestaunen

Media Releases Energy and Environment

Der am Paul Scherrer Institut PSI entwickelte Prozess der hydrothermalen Methanierung von wässriger Biomasse erreicht einen wichtigen Meilenstein: Dank der Zusammenarbeit im neuen Kompetenzzentrum des Bundes für Bioenergie BIOSWEET konnten Forschende des PSI, der ZHAW, der ETH Lausanne, der Empa und der Hochschule für Technik Rapperswil die technische Machbarkeit der Methanherstellung aus Mikroalgen demonstrieren. Der dazu verwendete Algenbioreaktor sowie die Anlage zur Methanierung der Algen können am 24. September auf dem Campus Grüental der ZHAW in Wädenswil besichtigt werden. Für Medienschaffende gibt es von 14:00 bis 14:30 eine spezielle Führung.

Mit Licht neues Material erzeugt

Media Releases Research Using Synchrotron Light Large Research Facilities Materials Research Matter and Material SwissFEL SwissFEL Experiments

Forschende des Paul Scherrer Instituts haben mithilfe kurzer Lichtblitze aus einem Laser die Eigenschaften eines Materials kurzzeitig so deutlich verändert, dass gewissermassen ein neues Material entstanden ist und die Veränderungen am Röntgenlaser LCLS in Kalifornien untersucht. Nach der Inbetriebnahme des PSI-Röntgenlasers SwissFEL werden solche Experimente auch am PSI möglich sein.

Jurassic Welsh mammals were picky eaters, study finds

Media Releases Research Using Synchrotron Light

New analyses of tiny fossil mammals from South Wales are shedding light on the function and diets of our earliest ancestors, a team led by researchers from the Universities of Bristol and Leicester report in the journal Nature. The team used CT scanning with synchrotron X-rays at PSI’s Swiss Light Source to reveal in unprecedented detail the internal anatomy of the mammals’ tiny jaws.

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 Research 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 Medicine 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.
