Injector 2: a pre-accelerator for protons
As fundamental building blocks of matter, protons are a part of all things that surround us. At the Paul Scherrer Institute PSI, however, they step out of their usual role and are deployed to generate other particles, namely neutrons and muons, which are subsequently used to study materials.

Making a valuable resource usable with water
Making a valuable resource usable with water
New reaction for converting methane into methanol In oil extraction sites, gaseous methane is simply burned, even though it could actually be a useful precursor material for fuels and products of the chemical industry. One way to make methane usable is to convert it to methanol. Being liquid, methanol is easier to transport than methane, and it can be used both as fuel and as raw material for the chemical industry.

Hydrogen inclusions mapped in high-resolution and in 3D
Using a nano-tomography method, material scientists have succeeded in localizing hydrogen inclusions within a structural metal in 3D for the first time. This was made possible by a uniquely modified measurement method developed at ETH Zurich. Hydrogen is a problem for many metals. If hydrogen atoms are included in a metal, the material properties can be severely affected, causing it to become brittle or cracked.
