Lisa-Sophie Ebers defends her doctoral dissertation

Lisa-Sophie Ebers defended successfully her doctoral dissertation on Nov. 9th 2020 entitled “Lignin-based inks for Direct Ink Writing”.

After completing her Master studies at the University of Freiburg in “Environmental Sciences” with the elective track “Biomaterials and Bioenergy”, Lisa-Sophie Ebers joined the Chair of Forest Biomaterials in May 2017. She started to work within the EU-project CARBOPREC: “Renewable source nanostructured precursors for carbon fibers”. Her dissertation was co-supervised by Prof. Thomas Speck.

In her dissertation, Lisa formulated fully bio-based inks for Direct Ink Writing, containing organosolv lignin and a cellulose derivative. From her dissertation, the following research papers were published:

The potential of the formulated lignin-based inks for lightweight applications was honored by Leichtbau BW with the ThinKing in November 2020 (https://www.youtube.com/watch?v=MY3QaAHKt6Y).
