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.

“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.

Mit Licht neues Material erzeugt

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

Forschende des Paul Scherrer Instituts haben mithilfe kurzer Lichtblitze aus einem Laser die Eigenschaften eines Materials kurzzeitig so deutlich verändert, dass gewissermassen ein neues Material entstanden ist und die Veränderungen am Röntgenlaser LCLS in Kalifornien untersucht. Nach der Inbetriebnahme des PSI-Röntgenlasers SwissFEL werden solche Experimente auch am PSI möglich sein.

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.

What attacks on oil pipelines have in common with epidemics

Energy and Environment

How susceptible is the global energy infrastructure to attacks by non-state actors? Has the number of attacks on this infrastructure actually increased of late? Which regions of the world are especially vulnerable? And which tactics do the attackers use? Scientists are looking to find the answers to these and other related questions with the aid of a database developed by researchers from the Center of Security Studies at ETH Zurich in collaboration with the Paul Scherrer Institute PSI.
