The MAPEX-CF allows scientists from several disciplines to share and access a wide range of high-performance scientific equipment capable of characterizing the structure and the chemical state of materials, ranging from entire components at the cm scale all the way down to the atomic resolution at the pm to nm scale.

We work together to push materials analytics beyond the state of the art in five investigation areas, coupling experimental characterization with materials modelling and simulation.

We use X-rays to non-destructively inspect the three-dimensional distribution of matter inside the object of investigation.

澳门皇冠_皇冠足球比分-劲爆体育

We investigate our samples using high-energy electron beams to obtain images with resolution down to the atom scale.

澳门皇冠_皇冠足球比分-劲爆体育

We combine microscopic and spectroscopic techniques to monitor processes at materials surfaces.

澳门皇冠_皇冠足球比分-劲爆体育

vertical Scanning Imaging and superimposed Raman Shift

We perform in-situ and real-time chemical, electronic and optical characterization of materials under different conditions, e.g. to identify and map different phases.

澳门皇冠_皇冠足球比分-劲爆体育

We support structure investigations of materials from crystalline nanomaterials to macroscopic single crystals at ambient and non-ambient conditions.

澳门皇冠_皇冠足球比分-劲爆体育

We develop and apply computational methods from quantum mechanics to continuum theories to design and understand new materials and processes.
