    At the Chair of Applied Laser Technologies (LAT) we focus on the two main application directions of laser technology, precision metrology and materials processing. In the area of laser materials processing we have strong and long term expertise in the use of ultrashort laser pulses and their interaction with different kind of materials in order to pattern surfaces or to generate structures with smallest dimensions of a few micrometer. Especially, our current research addresses the functionalization of surfaces by laser ablation and/or modification (e.g. flexible electronics based on graphene or other 2D materials which can be tailored according to the surrounding materials). Also we have made significant contribution to the research in additive manufacturing. Based on the two processes Selective Laser Melting (SLM) and Laser Materials Deposition (LMD) scientists at our chair were able to generate first components of high entropy alloys (HEA) with up to five equally distributed (refractory) elements in the powder blend. Also material systems composing of metals and polymers have been used in LMD to generate hybrid or graded components. Besides we work on further automation of these processes to make them more reliable and precise.

    Prof. Dr.-Ing. Jan T. Sehrt started his research activities in the field of additive manufacturing in 2003. He and his employees at the chair Hybrid Additive Manufacturing (HAM) – which was established at RUB in 2018 – offer an extensive expertise along the complete process chain of additive manufacturing. The chair deals with material modifications and investigations and has a high level of expertise in beam-matter interaction within the additive manufacturing process. Furthermore, the process qualification of new materials, the improvement of mechanical properties by influencing the material structure on the one hand and optimization of the surface structure on the other hand as well as hybrid part concepts and their qualification are within the R&D scope of HAM. Additionally research activities implement additive part design (e.g. optimization of topology, lightweight structures and integration of functionalities) and quality control within the additive manufacturing process as well as applied to the produced parts. Prof. Dr.-Ing. Jan T. Sehrt also implements into standardization work such as the VDI Technical Committee Additive Manufacturing (FA105), or as a German expert in other standardization committees for Additive Manufacturing such as ISO/TC 261 AM and NA 145-04-01 AA (DIN).

    Since 2011 I have been working as a research group leader at the Institute of Materials Technology of the Ruhr University Bochum. My research focusses on the development of new materials containing hard phases with improved mechanical, tribological and chemical properties. Material development takes into account aspects of metallurgy as well as technological constraints such as resource efficiency, cost-effectiveness and processability. For material development I use both computer-based and experimental methods. In principle, I consider the question of the relationship between the chemical composition and the stability of individual phases, the production-related structure formation processes and the associated material properties.

    The research at the Laboratory of Industrial Chemistry focuses on the synthesis and characterization of heterogeneous catalysts, which are essential for processes in chemical industry. We use a variety of synthetic methods such as impregnation, co-precipitation, spray drying or chemical vapor deposition, which are suitable for up-scaling. The catalysts are thoroughly characterized using bulk- and surface-sensitive methods complemented by advanced spectroscopy and transient kinetics. Finally, we analyze the catalytic performance under industrially relevant conditions studying methanol and Fischer-Tropsch synthesis or the synthesis of higher alcohols in the gas phase or selective oxidation and electrocatalysis in the liquid phase. We combine all these results to elucidate reaction mechanisms based on elementary steps and to improve the catalysts by rational design.

    The research at the Chair of Analytical Chemistry - Center for Electrochemical Sciences (CES) focuses on a broad spectrum of research fields from bioelectrochemistry to materials for energy conversion. Specifically we design electrocatalysts for important reactions for energy conversion e.g. for the hydrogen evolution reaction, the oxygen reduction reaction, the oxygen evolution reaction and the CO2 reduction reaction among others. The catalysts are evaluated using nanoelectrochemical techniques, high resolution local electrochemistry and hyphenated techniques combining electrochemistry with spectroscopy. Finally, we evalaute the reactions in model electrolyzers under close to industrial conditions. Main focus is on the elucidation of reaction mechanisms, structure-activity-stability relations and the design of improved catalysts.

    I am director at the Max-Planck-Institut für Eisenforschung GmbH in Düsseldorf and Professor at the Ruhr-Universität-Bochum. In my research team we mainly use advanced electron microscopy methods including aberration corrected scanning transmission electron microscopy, electron spectroscopy and X-ray diffraction/synchrotron radiation to study the microstructure of materials down to the atomic level. Small scale experimental testing methods are developed and applied to probe material properties with high spatial resolution and often under specific environmental conditions. Our micro-/nanomechanical experiments are combined with electron microscopy and/or diffraction to resolve the interplay of microstructure and properties and to use this knowledge for materials design. The materials portfolio stretches from thin films and coatings to alloys, steels and intermetallic phases. We have a global network of scientific partners and industrial cooperations across Europe.

Some examples include structural relaxation and viscoelastic properties of polymers and its possible application (e.g., shape memory effect), behaviour of molecular glasses under mechanical deformation (e.g., shear banding and its connection to anisotropy of correlations of non-affine strain), rheological response of complex fluids such as suspensions of colloidal particles and red blood cells as well as lattice Boltzmann modelling of wetting phenomena and capillarity. Quite recently, I have been also working on phase field modelling of surface diffusion and elasticity on the nanoscale.

    In my function as the head of the Institute for Building Materials at the Ruhr University Bochum, my research interests focus on the experimental investigation of cementitious materials, especially in tunneling and traffic areas, on the durability of concrete at chemical exposure, the effect of high-frequent cyclic stresses in the microstructure as well as shotcrete and fiber-reinforced concrete. In the course of the investigations numerous innovative test procedures and setups have been developed that allow the characterization of the behavior of cementitious materials from a microstructural to a macro level. Being a member of several normative panels it allows me to link the experimental research to the development of current national and international guidelines.

    I am director at the Max-Planck-Institut für Eisenforschung GmbH in Düsseldorf and Professor at the Ruhr-Universität-Bochum. In my research team we mainly use advanced electron microscopy methods including aberration corrected scanning transmission electron microscopy, electron spectroscopy and X-ray diffraction/synchrotron radiation to study the microstructure of materials down to the atomic level. Small scale experimental testing methods are developed and applied to probe material properties with high spatial resolution and often under specific environmental conditions. Our micro-/nanomechanical experiments are combined with electron microscopy and/or diffraction to resolve the interplay of microstructure and properties and to use this knowledge for materials design. The materials portfolio stretches from thin films and coatings to alloys, steels and intermetallic phases. We have a global network of scientific partners and industrial cooperations across Europe.

    The research activities at my chair of Physical Chemistry I aim at an atomic or molecular scale understanding of physical and chemical processes of adsorbates on surfaces in well-defined environments. For this aim, we fabricate and characterize hybrid surfaces of defined properties. The interaction of functionalized molecules with such surfaces is investigated microscopically and spectroscopically. We use light or electrons for a targeted initiation of non-adiabatic reactions. Finally, the environment of the molecules is altered to steer the reactions. Our research presents an important link between applied research at ensembles and theoretical descriptions of individual molecules. At present the major subtopics are ‘Kinetics of nanostructures’, ‘Local variation of surface properties’, ‘Solvation-driven photolysis’, and ‘Confinement-controlled chemistry’.

    The research at the Laboratory of Industrial Chemistry focuses on the synthesis and characterization of heterogeneous catalysts, which are essential for processes in chemical industry. We use a variety of synthetic methods such as impregnation, co-precipitation, spray drying or chemical vapor deposition, which are suitable for up-scaling. The catalysts are thoroughly characterized using bulk- and surface-sensitive methods complemented by advanced spectroscopy and transient kinetics. Finally, we analyze the catalytic performance under industrially relevant conditions studying methanol and Fischer-Tropsch synthesis or the synthesis of higher alcohols in the gas phase or selective oxidation and electrocatalysis in the liquid phase. We combine all these results to elucidate reaction mechanisms based on elementary steps and to improve the catalysts by rational design.
