Scientists use nano-rods to investigate how matter assembles
To make the magnetic interactions between the atoms visible, scientists at the Paul Scherrer Institute PSI have developed a special model system. It is so big that it can be easily observed under an X-ray microscope, and mimics the tiniest movements in Nature. The model: rings made from six nanoscale magnetic rods, whose north and south poles attract each other. At room temperature, the magnetisation direction of each of these tiny rods varies spontaneously. Scientists were able to observe the magnetic interactions between these active rods in real time. These research results were published on May 5 in the journal “Nature Physics”.

Forscher des PSI und der ETH Zürich haben mit Kollegen vom Politecnico di Milano in der aktuellen Ausgabe der wissenschaftlichen Fachzeitschrift "Nature Photonics" eine Methode erarbeitet, einen Laser zu entwickeln, der schon bald in den neuesten Computern eingesetzt werden könnte. Damit könnte die Geschwindigkeit, mit der einzelne Prozessorkerne im Chip miteinander kommunizieren, drastisch erhöht werden. So würde die Leistung der Rechner weiter steigen.

Lithium-ion batteries are high performance energy storage devices used in many commercial electronic appliances. Certainly, they can store a large amount of energy in a relatively small volume. They have also previously been widely believed to exhibit no memory effect. That’s how experts call a deviation in the working voltage of the battery, caused by incomplete charging or discharging, that can lead to only part of the stored energy being available and an inability to determine the charge level of the battery reliably. Scientists at the Paul Scherrer Institute PSI, together with colleagues from the Toyota Research Laboratories in Japan have now however discovered that a widely-used type of lithium-ion battery has a memory effect. This discovery is of particularly high relevance for advances towards using lithium-ion batteries in the electric vehicle market. The work was published today in the scientific journal Nature Materials.
8. April 2013Media Releases SwissFEL Matter and Material
Prominent among the planned applications of X-ray free electron laser facilities, such as the future SwissFEL at the Paul Scherrer Institute, PSI, are structural studies of complex nano-particles, down to the scale of individual bio-molecules. A major challenge for such investigations is the mathematical reconstruction of the particle form from the measured scattering data. Researchers at PSI have now demonstrated an optimized mathematical procedure for treating such data, which yields a dramatically improved single-particle structural resolution. The procedure was successfully tested at the Swiss Light Source synchrotron at PSI.
3. April 2013Media Releases Matter and Material Research Using Neutrons
Developmental Engineers from the firm LuK (D) wanted to see right through the metal housing of a clutch. They wanted to observe how the oil that lubricates and cools a clutch is distributed. A transparent disc becomes dirty very quickly, and X-rays merely reveal the metal. These engineers therefore turned to scientists at the Paul Scherrer Institute, who illuminated the metal with neutrons and thus made the lubricating oil visible. The results surprised everyone: only three of the eight lamellae were sufficiently lubricated.

For the first time, experiments using computed tomography have allowed scientists to observe in 3D the flow of oil and water in real rock on an unprecedented scale. The new approach trailed and the information gathered by the experiments contribute to an improved understanding of multiphase flow and transport in porous media.
22. February 2013Media Releases SwissFEL SwissFEL Construction
A new Large-Scale Research Facility, SwissFEL, is to be built in the Würenlingen forest, very close to the Paul Scherrer Institute (PSI). On Friday, February 22, 2013, the building permit was signed with the Citizens’ Commune of Würenlingen.
14. February 2013Media Releases Biology Human Health
Numerous processes taking place within our body, such as sight, smell or taste, are accomplished by an important family of sensors on cell surfaces, which are known as G protein-coupled receptors (GPCR). Researchers have now compared the hitherto known structures of GPCRs and discovered a stabilising framework of fine struts that is characteristic for the architecture of the entire GPCR family. Knowledge about this constructional feature, which has been conserved over the course of evolution, can be of significant assistance in the development of new pharmaceuticals.
12. February 2013Media Releases Matter and Material Research Using Synchrotron Light
Scientists at the Paul Scherrer Institute, together with Chinese and German collaborators, have obtained new insights into a class of high-temperature superconductors. The experimental results of this fundamental research study indicate that magnetic interactions are of central importance in the phenomenon of high-temperature superconductivity. This knowledge could help to develop superconductors with enhanced technical properties in the future.

Joint venture in the bioenergy and resource efficiency sector: PSI and FHNW establish joint instituteMedia Releases Energy and Environment Renewable Energies
The Institute of Biomass and Resource Efficiency was founded by the two institutions, PSI (Paul Scherrer Institute) and FHNW (University of Applied Sciences Northwestern Switzerland), at the start of 2013. The aim of this new institute is to tackle the issue of resource efficiency throughout Switzerland, concentrating simultaneously on energy and material for the first time, and to thus make a significant contribution to the Federal Government’s "Energy Strategy 2050". The focus is on the sustainable use of biomass.
