Dr. Anna Sandak together with colleagues Julia Tomasich from TU Wien and Lignovations GmbH, René Herrera Díaz and Oihana Gordobil from the University of Basque Country UPV/EHU, Michael Harasek from TU Wien, Stefan Beisl from Lignovations GmbH, recently published an article Photochemical behavior of colloidal lignin particles under controlled UV exposure: Balancing self-stabilization and degradation in the International Journal of Biological Macromolecules.

This study investigates the photochemical behavior of CLPs under ultraviolet irradiation synthetized from five different technical raw lignins (Alkali, Organosolv, two Enzymatic Hydrolyzed and Softwood Kraft Lignin) via solvent-shift procedure. The findings provide valuable insights into the degradation pathways and stability across different environmental contexts, which can contribute to understanding the potential environmental impact of CLPs in aquatic ecosystems.
