When thawing glaciers release pollutants

Media Releases Energy and Environment Environment

As glaciers increasingly melt in the wake of climate change, it is not only the landscape that is affected. Thawing glaciers also release many industrial pollutants stored in the ice into the environment. Now, within the scope of a Swiss National Science Foundation project, researchers from the Paul Scherrer Institute (PSI), Empa, ETH Zurich and the University of Berne have measured the concentrations of a class of these pollutants – polychlorinated biphenyls (PCB) – in the ice of an Alpine glacier accurately for the first time.

Puzzling new behaviour observed in high-temperature superconductors

Media Releases Matter and Material Materials Research Research Using Synchrotron Light

New effect might be important for emergence of High-Temperature Superconductivity
An international team of researchers has observed a new, unexpected kind of behaviour in copper-based high-temperature superconductors. Explaining the new phenomenon – an unexpected form of collective movement of the electrical charges in the material – poses a major challenge for the researchers. A success in explaining the phenomenon might be an important step toward understanding high-temperature superconductivity in general. The crucial experiments were conducted at the Paul Scherrer Institute.

Useful for spintronics: Big surprises in a thin surface region

Media Releases Research Using Synchrotron Light Materials Research Matter and Material

The need for ever faster and more efficient electronic devices is growing rapidly, and thus the demand for new materials with new properties. Oxides, especially ones based on strontium titanate (SrTiO3), play an important role here. A collaborative project headed by scientists from the PSI has now revealed properties of strontium titanate that make it an important base material for applications in spintronics.

“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.

New material generated with light

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

PSI researchers garner experience for SwissFEL experiments
Aided by short laser flashes, researchers at the Paul Scherrer Institute have managed to temporarily change a material’s properties to such a degree that they have – to a certain extent –created a new material. This was done using the x-ray laser “LCLS” in California. Once the PSI x-ray laser SwissFEL is up and running, experiments of this kind will also be possible at PSI.

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.
