Research
Our research focus is the investigation of structural, topographical, and chemical changes taking place on the surface and in the bulk of materials during their synthesis, manufacturing, and use. To this aim, we will perform in-situ and real-time studies, establishing correlated workflows between different characterization techniques.
In-situ, real-time investigations
By using specially designed holders capable of putting samples under mechanical, thermal, or chemical loads and gradients, different kinds of in-situ and real-time studies can be performed at the MAPEX-CF. Different environmental chambers, heating/cooling stages, low-pressure gas injection nozzles, and mechanical testing stages installed at our diffraction, spectroscopy, and microscopy instruments allow for state-of-the-art materials analytics research.
Correlated Workflows
In order to test, image, and analyze the same sample regions with complementary techniques, correlated workflows between instruments are being constantly implemented at the MAPEX-CF. Retrieving the 3D chemical composition of different samples utilizing a correlated XRM and EDX + FIB/SEM approach and a combination of VSI/Raman spectroscopy with fast-scan AFM are some examples of already established workflows.

Influence of chemical zoning on sandstone calcite cement dissolution: The case of manganese and iron
High-throughput screening
Being capable of analyzing a large number of samples in the shortest possible time with a large degree of automatization is one of the main goals of the MAPEX-CF. To this aim, the implementation of robotic arms and other enabling technologies are foreseen.

Materials Modeling
In close cooperation with the Bremen Center for Computational Materials Science (BCCMS), the experimental information obtained at MAPEX-CF is combined with materials modeling at several scales. TEM and XRD studies in combination with DFT calculations and AFM measurements together with coarse-grained dissipative particle dynamics simulations are only a few examples of the work jointly carried out between the MAPEX-CF and the BCCMS.
