Nina Kølln Wittig

During her PhD studies, Nina Kølln Wittig researched in biological and bioinspired materials. Biological materials such as bone, blue mussel glue, or brilliantly colored animal skin, are characterized by multi-functionality and properties that are superior to most manmade materials. The secret to these properties is often found in the structure of the material with important structural features ranging length scales from the atomic to the anatomic. Nina Kølln Wittig studied the ultrastructure of bone with the goal of reaching a better understanding of this particular biological material. Furthermore, she made materials for use in bioinspired reflectors with stimuli-responsive colors.

The new findings reveal that the structure of bone is more complex and heterogeneous than hitherto believed, and have taken significant steps towards the realization of bioinspired reflectors based on an organic crystal with superior reflective properties.

The PhD study was completed at the Interdisciplinary Nanoscience Center (iNANO) and Department of Chemistry, Faculty of Natural Sciences, Aarhus University.

This summary was prepared by the PhD student.
