The affect of chemical structure and morphology on the material performance of lignin-based materials will be investigated along with the behavior […]
Water based wood treatment
For a more sustainable production of wood aerogel, treatment with the water based solvent, NaOH, can give the wood template a porous structure in sub-zero conditions. However, it is found that the porosity of the wood templates treated with NaOH (aq) can be affected at room temperature conditions as well. Towards a greener aerogel production, […]

Cellulosed based foams for water purification
We have designed foams which are built only from green components and can be prepared in up-scalable and easy manner: blending and oven-drying. Amyloid nanofibrils are used mainly as a foaming agent and cellulose nanofibrils are playing the role of the main visco-elastic stabilizer. We also use covalent cross-linking to enhance foam resistance towards capillary […]
