Email: andreas.ostendorf@rub.de
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.

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.

It is a major challenge of our time to develop sustainable chemical processes and to reduce the amount of waste generated by the chemical industry. Particularly solvents, often harmful for the environment, accumulate in many of the chemical processes. Our group develops new synthesis concepts, completely avoiding the use of any solvents. These syntheses are based on mechanochemistry. We utilize mechanical energy, which is brought into the system by ball milling, to initiate chemical reactions, rather than temperature as in conventional thermally-induced reactions. With this, an unconventional chemistry is possible with different reaction mechanism, reaction products, and product selectivities as compared to classical solvent-based syntheses. We are focusing on the mechanochemical synthesis of polymers, ceramics, and nanostructured materials such as porous carbons, polymer frameworks and nanographenes. We are motivated by the fundamental curiosity how ball-milling, commonly utilized to destroy matter, can be applied to construct fragile and defined materials.

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.

Particularly solvents, often harmful for the environment, accumulate in many of the chemical processes. Our group develops new synthesis concepts, completely avoiding the use of any solvents. These syntheses are based on mechanochemistry. We utilize mechanical energy, which is brought into the system by ball milling, to initiate chemical reactions, rather than temperature as in conventional thermally-induced reactions. With this, an unconventional chemistry is possible with different reaction mechanism, reaction products, and product selectivities as compared to classical solvent-based syntheses. We are focusing on the mechanochemical synthesis of polymers, ceramics, and nanostructured materials such as porous carbons, polymer frameworks and nanographenes. We are motivated by the fundamental curiosity how ball-milling, commonly utilized to destroy matter, can be applied to construct fragile and defined materials.

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.

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 was born in 1960 in Warstein. I’m married and father of two daughters. I studied Chemistry at the Westfälische Wilhelms-Universität (Münster), where I received my doctorate in 1988. Additionally, in 1989, I passed the First State Exam in Law. After 5 years as scientific assistant at the Johannes-Gutenberg-Universität (Mainz) I became Professor in Chemistry in 1995. From 1995 till 1998 I worked as Professor for Inorganic Chemistry at the Johann-Wolfgang-Goethe-Universität (Frankfurt). Since 1998 I’m Director at the Max-Planck-Institut für Kohlenforschung (Mülheim an der Ruhr) and since 2014 Vice-President of the Max-Planck-Gesellschaft (Munich). My research field comprises: energy, biomass conversion, crystallization processes, synthesis of catalyst materials, catalysis, zeolites, ordered mesoporous materials and hydrogen storage materials.

In 2011 I've completed my PhD in Biology and Biotechnology within the DFG SPP1313 „Nano-Bio-Response“ at the Surgical Research (University Hospital Bergmannsheil). After a brief time as Post Doc during which I´ve worked on nanostructured surfaces as anti-infective strategy I was appointed in 2015 as a Junior-professor. My research fields ranges from applied material science for the development and testing of new biomaterials to new possibilities provided by nanotechnology to combat e.g. bacterial infections to the regenerative medicine which includes the use of autologous stem cells for neuroregenerative approaches. In my lab we use a broad spectrum of methods ranging from microbiology, cell biology, confocal laser scanning microscopy to electron microscopy on diverse current projects from stem cell research to neurotraumatology.

I am currently building up a new quantum materials group at the physics department of the Ruhr-University. Our goal is to elucidate the interaction of correlated electronic phases with each other, with the crystal lattice and with the environment by a variety of experimental techniques. We will prepare singly-crystalline samples and study their structural, electrical, thermodynamic and mechanical properties in a wide and cryogenic temperature range and also in high magnetic fields. By manipulating these materials, we aim to discover new physics and interesting functional properties.

I studied geosciences at Presidency College and Calcutta University in India and then did a PhD at the Unviersity of Arizona in the USA. This was followed by post-doctoral positions at Bayreuth and Cologne, leading to a habilitation degree at Cologne. After that I became a professor at the Ruhr University at Bochum, and have held visiting positions at the University of California, Berkeley; University College Dublin, Trinity College Dublin, the University of Oviedo, and the IISER-Kolkata in India. I am an associate editor for the journal Earth and Space Chemistry that was recently established by the American Chemical Society, and have held several committee positions in different societies such as the Mineralogical Society of America and American Geophysical Union. I was a distinguished lecturer of the Mineralogical Society of America and was awarded the Dana Medal by them in 2016. The petrology group at Bochum specializes in timescales of geological processes. This is done through the study of diffusion and other kinetic processes in solid and molten material, with an emphasis on silicates and oxides. Specific skills lie in the areas of production of thin films using pulsed laser deposition (PLD), study of point defect thermodynamics and diffusion mechanisms, determination of diffusion coefficients and phase relations at high pressures, and nanoscale chemical analysis (high resolution, FEG-based electron microprobe analyses; RBS, NRA, PIXE etc. at the accelerator facility at RUBION; SIMS analyses at CENIDE in Duisburg within the scope of the Ruhr alliance). Modelling of solid state diffusion-based kinetic processes is another area of expertise.

I’ve completed my PhD in Materials Science at the P’ Institute (Insitut Polytechnique de Poitiers, France) in 2011. After a brief time as a Humboldt fellow at the Ruhr-University Bochum during which I've worked on small-scale mechanical behavior of shape memory alloys, I was appointed in 2016 as a Junior-professor. My main research activities cover investigations on the relationship between processing parameters, microstructures and mechanical properties of metallic and intermetallic materials. Currently the main focus of my research group “Microstructure of materials” is on High-entropy alloys. In particular I study the effect of the chemical composition on mechanical properties as well as phase stability and precipitation kinetics.
