14. July 2014Energy and Environment Nuclear Power Plant Safety
In nuclear reactors, water is dissociated at the surface of the hot fuel elements, thereby producing hydrogen. This hydrogen can penetrate the fuel cladding surrounding the actual fuel and weaken it mechanically. Researchers from the Paul Scherrer Institute (PSI) have been using neutrons and synchrotron radiation to study how the hydrogen gets into the cladding tube and what impact it can have once inside.

The molecule dicarbon (C2) is present in all flames where a carbon-containing fuel is combusted. C2 burns visibly, is behind the blue colour inside a candle flame and could also play a key role in the formation of soot. Now, for the first time, scientists from the Paul Scherrer Institute have rendered a previously invisible C2 energy state, a so-called dark state, visible. Not only is its discovery interesting for combustion researchers; it also solves a century-old puzzle in the spectrum of this omnipresent molecule.

16. June 2014Media Releases Energy and Environment Research Using Neutrons
Researchers from the Paul Scherrer Institute (PSI) have succeeded in imaging the distribution of frozen and liquid water in a hydrogen fuel cell directly for the first time. They applied a new imaging technique that uses successively two beams with different neutron energies to distinguish between areas with liquid water and those with ice extremely reliably. The method therefore opens up the prospect of studying one of the main problems of using fuel cells to power vehicles: ice can clog the pores in the fuel cells and affect their performance. The PSI scientists’ results will be published in the journal Physical Review Letters on 16 June 2014.
11. June 2014Media Releases Research Using Synchrotron Light
Researchers from the Paul Scherrer Institut (PSI) have devised a method that opens up new scales of tomographic imaging and will thus allow in the future highly resolved measurements of biological and materials science specimens. With the aid of a special prototype instrument at the Swiss Light Source (SLS), they achieved a 3D resolution of sixteen nanometres in a large sample and thus set a new world record in X-ray tomography.
