Section of Functional Materials and Nanotechnology

«Teaching does much, but encouragement does everything.»

- Johann Wolfgang von Goethe -

Prof. Dr. Christian Adlhart

Head of Section Functional Materials and Nanotechnology

The Section Functional Materials and Nanotechnology research and development is done wherever materials are used at interfaces. For us, research on smart materials means developing fibers that deliver drugs to a specific target or that fulfill specific functions such as the separation of chromium from wastewater. This is achieved by selectively tailoring their surface functionality. Smart materials also involves finding ways to replace existing materials with biomaterials or synthesizing fibers that harvest CO2 from air. We generate our nanofibers by electrospinning in the laboratory and at pilot scale. We also have a wide range of microscopic and spectroscopic techniques for characterization and functional testing of materials.
