Porous Nanocomposites research group

The most important scientific results of the research group

We pioneered the development of evaporation profile based microanalytics and gained insight into the wetting properties of nanoporous materials composed of 1D nanostructures. These results have logically lead us towards wetting and wicking phenomena in other fibrous material based composites, e.g. nonwoven textiles, oil adsorbent materials, and battery AGM separators. We synthesize and develop new nanostructures for usage in nanocomposites. Recently we made progress towards understanding the redox behavior of phosphorene layers synthesized by the exfoliation of black phosphorous, and we have contributed to the development of various catalyst supports as well as double and triple perovskites. We put an emphasis on developing our measuring and data evaluation methods. Our most recent success story in this field is the development of a novel micro-CT quantification algorithm for the quantitative assessment of spatial inhomogeneity in porous bodies.

Results of the last 1 year

We participated in developing hierarchic self-similar systems (1-2) and double and triple perovskites (3-4). We succeeded in explaining the changes observable in the electric properties of phosphorene during oxidation by structural changes (5-6). We introduced a new method for calculating lacunarity, that can speed up the quantitive analysis of micro-CT datasets by three orders of magnitude.
