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: Structure of Matter; 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.Current news from PSI

Understanding plastic semiconductors better
Semiconductors made from polymer materials are becoming increasingly important for the electronics industry – as a basis for transistors, solar cells or LEDs. Usually, they consist of more than one substance as they get their particular electric properties only when several materials are blended. Researchers from the Paul Scherrer Institute and the University of Cambridge have developed a method that allows them to determine the detailed structure of the material.22. July 2010
New X-ray technique distinguishes between that which previously looked the same
Images generated using the phase-contrast technique allow one to distinguish between tissue types such as muscle, cartilage, tendons or soft-tissue tumours that look virtually identical in conventional X-ray images. Researchers at the Paul Scherrer Institute and the Chinese Academy of Science have further developed the technique to make it easier to use in the future. This could help in the detection of tumours or in the identification of hazardous objects in luggage.8. July 2010
Protons – smaller than we thought
The proton – one of the smallest building-blocks of all matter – is even smaller than had previously been assumed. This discovery is the result of experiments carried out at the Paul Scherrer Institute (PSI) in Villigen, Switzerland, by an international research team.Information for
