Future-oriented research requires facilities that are continually brought up to date. That’s why PSI is currently planning a significant upgrade to its proton accelerator with the project IMPACT. Physicist Daniela Kiselev is head of Accelerator Operation and Development at PSI. In addition, she is leading the project management team for IMPACT. In this interview, she talks about the smallest particles and the big plans for the renovation.

Researchers have trained an artificial intelligence to design the structure of so-called metamaterials with desired mechanical properties for a wide range of applications.

Researchers from ETH Zurich, Empa and Stanford have taken snapshots of the crystal structure of perovskite nanocrystals as it was deformed by excited electrons. To their surprise, the deformation straightened out the skewed crystal structure rather than making it more disordered.

Modelled on nature: researchers have developed a new material that replicates the structure responsible for the blue feathers of the North American song bird, among many other birds. It also has other striking advantages.

A doctoral researcher studying architecture at ETH Zurich is using 3D printing to produce lightweight insulation building components from cement-free mineral foams derived from recycled industrial waste. These could cut heating and cooling costs for buildings, and encourage more efficient use of construction materials.

A team of experts from EPFL, ETH Zurich and a Geneva-based architecture firm has developed a new type of non-reinforced concrete made from stone offcuts. Their method, which reduces the use of carbon-intensive cement-based binders, draws on ancient techniques uncovered in historical archives.
