Interface Science Department

Our department investigates the unique structural, electronic, vibrational and chemical properties of size- and shape-selected nanostructures and thin films and their interfaces with gas and liquid environments.

Understanding the interplay between the numerous factors determining the physico-chemical behavior of such systems is crucial for optimizing their efficiency for applications in catalysis and more specifically in energy conversion. To this end, advanced synthesis methods and in situ / operando surface/bulk-sensitive characterization techniques are being employed in our department for the fundamental understanding of catalysts “at work”.

European Research Council (ERC) has awarded a Starting Grant of 1.75 million Euros to Dr. Sebastian Öner

The European Research Council (ERC) has awarded a Starting Grant of 1.75 million Euros to Dr. Sebastian Öner, group leader at the Interface Science Department of the Fritz Haber Institute. Dr. Öner’s research aims at sensing and controlling ions at liquid-solid and vapor-solid interfaces that are broadly relevant across many scientific domains, including electro-, thermal- and biochemistry. With the ERC grant ORION, Dr. Öner’s group will develop a new electrochemical scanning probe microscopy that enables spatial control over the free energy of interfacial ions, such as protons (H+) and hydroxide ions (OH-) during interfacial water dissociation (H2O-> H+ + OH-).

German Federal Minister of Education and Research in Berlin-Adlershof

The Federal Minister of Education and Research, Bettina Stark-Watzinger, visited the Catalysis Laboratory (CatLab) in Berlin-Adlershof. CatLab is a research platform for catalysis research supported by the Fritz Haber Institute of the MPG, the Max Planck Institute for Chemical Energy Conversion and the Helmholtz Center Berlin. The aim of the joint project is to develop important innovations that will contribute to the realization of a green hydrogen economy. During her visit to the CatLab, the minister gained insight into the latest technological developments for the production and characterization of thin-film catalysts as well as special methods for operando analytics and digital catalysis.

Royal interest in clean energy storage - King Felipe the VI of Spain visited the Fritz Haber Institute

On Monday, 17 October 2022, King Felipe VI and Queen Letizia of Spain began their three-day visit to Germany with a reception hosted by President Frank-Walter Steinmeier at Bellevue Palace. The Spanish royal couple last visited Germany together in 2014. In the evening, the Federal President will host a state banquet in honour of the royal couple. The afternoon, however, was all about science: King Felipe, who is interested in the subject of energy,  paid a visit to Fritz Haber Institute of the Max Planck Society, together with his wife Queen Letizia, to inform himself about the institute’s energy research. more
