Tiny Magnets as a Model System

Media Releases Matter and Material Materials Research Research Using Synchrotron Light

Scientists use nano-rods to investigate how matter assemblesTo 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”.

Memory effect now also found in lithium-ion batteries

Media Releases Energy and Environment Industrial co-operation

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.

X-ray Laser: A novel tool for structural studies of nano-particles

Media Releases Large Research Facilities 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.

Observing Engine Oil Beneath Metal

Media 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.

A glimpse inside the control centres of cell communication

Media 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.

Imaging fluctuations with X-ray microscopy

Media Releases Matter and Material Research Using Synchrotron Light

X-rays are used to investigate nanoscale structures of objects as varied as single cells or magnetic storage media. Yet, high-resolution images impose extreme constraints on both the X ray microscope and the samples under investigation. Researchers at the Technische Universität München the PSI now showed how to relax these conditions without loss of image quality. They further showed how to image objects featuring fast fluctuations, such as the rapid switching events that determine the life time of data storage in magnetic materials.

Magnetic nano-chessboard puts itself together

Media Releases Micro- and Nanotechnology Materials Research Matter and Material Research Using Synchrotron Light

Researchers from the Paul Scherrer Institute and the Indian Institute of Science Education and Research have been able to intentionally ‘switch off’ the magnetization of every second molecule in an array of magnetized molecules and thereby create a ‘magnetic nano-chessboard’. To achieve this, they manipulated the quantum state of a part of the molecules in a specific way.

The weak side of the proton

Media Releases Matter and Material Research with muons Particle physics

An international research team has determined with a high level of accuracy, how the proton participates in the weak interaction à one of the fundamental forces of nature. Their results confirm the predictions of the Standard Model of particle physics. The experiment observed the probability of muon capture by protons à a process governed by the weak interaction. The experiment was conducted at the Paul Scherrer Institute, the only institute in the world with an accelerator capable of generating enough muons for carrying out this project in a realistic timeframe.

How stabilised cell fibres prevent cancer cell division

Media Releases Human Health Biology Research Using Synchrotron Light

Anti-cancer drugs are used under the heading of “Chemotherapeutics” to prevent cells from dividing. Because the cells in a growing tumour divide more frequently than others, tumour cells are damaged more severely. Scientists at the Paul Scherrer Institute and the ETH Zurich have now clarified the exact mechanism of action of one class of these drugs. The data acquired is so accurate, that targeted drugs could now be developed that are even better suited to fulfil their task.

The evolutionary origins of our pretty smile

Media Releases Biology User experiments Research Using Synchrotron Light

Until recently, it was not obvious whether the earliest vertebrates (animals with a backbone) which had jawbones already possessed teeth or not. Now, an international research team has shown that the jaws of the prehistoric fish Compagopiscis already had teeth. This means that teeth appeared at the same evolutionary time as jaws à or at least shortly afterwards. The leaders of this project were scientists from the University of Bristol, England, who carried out their decisive experiments at the SLS at PSI.
