Paul Scherrer Institute

The Paul Scherrer Institute, PSI, is the largest research centre for natural and engineering sciences within Switzerland. We perform world-class research in three main subject areas: Matter and Material; Energy and the Environment; and Human Health. By conducting fundamental and applied research, we work on long-term solutions for major challenges facing society, industry and science.

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.

SwissFEL experiments without SwissFEL

SwissFEL SwissFEL Experiments Large Research Facilities

For many years, PSI researchers have been testing experimental methods that will provide insights into novel materials for electronic devices. Using a special trick to make the Swiss Light Source (SLS) at PSI generate light with similar properties to that of PSI’s x-ray laser SwissFEL, the researchers were able to demonstrate that the experiments planned for SwissFEL are possible and they are now building an experimental station at SwissFEL.

PSI expertise boosts research for the energy transition

Energy and Environment

Researchers from the Paul Scherrer Institute (PSI) are involved in several projects under the new National Research Programme “Energy Turnaround” (NRP70) of the Swiss National Science Foundation (SNSF). The PSI experts tackle issues such as particle emissions from wood heating systems, the holistic evaluation of energy systems and the production of semiconductor components for novel transformers.

Neuer Laser für Computerchips

Media Releases Matter and Material Materials Research

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.
