The IMPRESS interoperable platform.

The project aims to develop an interoperable platform consisting of both hardware and software components based on a modular and standardized cartridge concept.

The cartridges are designed to be inserted in an automated or semi-automated way into TEM specimen and aperture holders, as well as other instruments for preparation and characterization, including surface science tools, transport measurements, microfocus X-ray tomography instruments, and synchrotrons.

They provide the flexibility for samples to be cooled, heated, in vacuum, or in an inert gas across different methods and analytical techniques, while ensuring sample cleanliness is maintained.
