Nanometres in 3D

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

Scientists at the Paul Scherrer Institute and ETH Zurich have created 3D images of tiny objects showing details down to 25 nanometres. In addition to the shape, the scientists determined how particular chemical elements were distributed in their sample and whether these elements were in a chemical compound or in their pure state.

Gasoline beats mining

Media Releases Environment

Until it was banned, leaded gasoline dominated the manmade lead emissions in South America
Leaded gasoline was a larger emission source of the toxic heavy metal lead than mining in South America – even though the extraction of metals from the region’s mines historically released huge quantities of lead into the environment. Researchers from the Paul Scherrer Institute PSI and the University of Bern have discovered evidence of the dominance of leaded gasoline based on measurements in an ice core from a Bolivian glacier. The scientists found that lead from road traffic in the neighbouring countries polluted the air twice as heavily as regional mining from the 1960s onwards. The study is to be published in the journal Science Advances on 6 March 2015.

Neuer Laser für Computerchips

Media Releases Matter and Material Materials Research Micro- and Nanotechnology

Germanium-Zinn-Halbleiterlaser lässt sich direkt auf Siliziumchips aufbringen
Winzige Laser, die in Computerchips aus Silizium eingebaut werden, sollen in Zukunft die Kommunikation innerhalb der Chips und zwischen verschiedenen Bauteilen eines Computers beschleunigen. Lange suchten Experten nach einem dafür geeigneten Lasermaterial, das sich mit dem Fertigungsprozess von Siliziumchips vereinbaren lässt. Wissenschaftler des Forschungszentrums Jülich und des Paul Scherrer Instituts PSI haben hier nun einen wichtigen Fortschritt erzielt.

Batman lights the way to compact data storage

Media Releases Matter and Material Research Using Synchrotron Light Materials Research

Researchers at the Paul Scherrer Institute (PSI) have succeeded in switching tiny, magnetic structures using laser light and tracking the change over time. In the process, a nanometre-sized area bizarrely reminiscent of the Batman logo appeared. The research results could render data storage on hard drives faster, more compact and more efficient.

Shortcut to protein portraits

Media Releases Research Using Synchrotron Light Biology

All living organisms, from bacteria to humans, rely on proteins to perform their vital functions. How these proteins accomplish their tasks depends on their structure. Researchers from the Paul Scherrer Institute have now devised a novel method to determine the crystal structure of proteins using X-ray light, which could also hasten the development of new drugs in future. The study will be published in the journal Nature Methods on 15 December.

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.
