Preserving film sound in the cold at the British Film Institute: new evidence for archives

Can magnetic film sound be stored in the cold? A collaboration between the British Film Institute and PSI found no detectable damage in the studied samples and points to a broader future for archives, in which laboratory methods and synchrotron techniques at the Swiss Light Source SLS help guide the preservation of complex audiovisual media.

In-situ straining with a MEMS device

Researchers from an international collaboration between Switzerland, Italy, Germany, and Taiwan have developed a device for the in situ straining of freestanding ferroic films alllowing for ptychographic imaging whilst applying a mechanical strain. The results have been published as Editors' Suggestion within Physical Review B.
