The Paul Scherrer Institute (PSI) is a multi-disciplinary research institute which belongs to the Swiss ETH-Komplex covering also the ETH Zurich and EPFL. It was established in 1988 by merging in 1960 established EIR (Eidgenössisches Institut für Reaktorforschung = Federal Institute for Reactor Research) and in 1968 established SIN (Schweizerisches Institut für Nuklearphysik = Swiss Institute for Nuclear Physics). The PSI is a multi-disciplinary research centre for natural sciences and technology. In national and international collaboration with universities, other research institutes and industry, PSI is active in solid state physics, materials sciences, elementary particle physics, life sciences, nuclear and non-nuclear energy research, and energy-related ecology. It is the largest Swiss national research institute with about 1,400 (year 2011) members of staff, and is the only one of its kind in Switzerland. PSI is a User Laboratory and runs several particle accelerators. The 590MeV cyclotron, with its 72MeV companion pre-accelerator, is one of them. As of 2011, it delivers up to 2.2mA proton beam, which is the world record for such proton cyclotrons.
Scientists use nano-rods to investigate how matter assembles
(Phys.org) —In the microscopic world, everything is in motion: atoms and molecules vibrate, proteins fold, even glass is a slow flowing liquid. And during each movement there are interactions between the ...

Observing engine oil beneath metal: Scientists reveal how lubricant oil disperses in a functioning clutch
Lubricating oil is essential for engines. Multi-disc clutches, like those found in motorcycles, are also lubricated and cooled with oil. The oil pump has to be driven by the engine at the same time, thus ...

Silicon nanowires under extreme tensile strain may lead to more efficient transistors
Stretching a layer of silicon can build up internal mechanical strain which can considerably improve its electronic properties. With strained silicon, one can, for example, build faster and less power-consuming ...
