Purpose of the project is to study mass transport of ionic liquids into wood pieces and fibers and consequent lignin and hemicellulose transport out from the pieces. Therefore, characterisation techniques to investigate the location of ionic liquids and lignin in the fiber structure are needed to be developed. Examples of such techniques are X-ray imaging, […]

This project will develop a new generation of functional hydrogels using cell wall polysaccharides and polyphenols from plant side streams, combining the material properties of the polysaccharides and the antioxidant properties of polyphenols. This project contributes to a circular biomass utilisation exploiting abundant by-products from agricultural production.

Our project focuses on hemicelluloses, as they play an important role within lignocellulosic biomass, interlocking cellulose microfibrils, and lignin. Hemicelluloses affect the mechanical properties of cellulose fiber surfaces by creating rigid and flexible domains. The vision of the project is to unlock the full potential of hemicelluloses in wood and open the way for a

In this project, the fiber wall is modified to enable diffusion of functional monomers and subsequent polymerization and crosslinking within the wet-fiber wall resulting in a stiff and elastic fiber-composite. The fibers are modified in a fully biobased system and the end material is biocompatible and degradable.

In this project we will engineer hemicellulose hydrogels using a wide range of enzymes, from oxidative laccases that introduce crosslinking to specific hydrolases that cleave selectively side chains from the hemicelluloses. We expect that the enzymatic treatments will modulate the network interactions in the hydrogels and the rheological properties. We will investigate the morphology and

Electrocatalytic reaction is a green technology for sustainable energy conversion, materials design, environment remediation, and green chemistry, where the role of catalyst is essential. Hierarchical structures combining multi-scale pores are favorable due to combined high specific surface area, mass diffusion in the structure and accessibility to the surface. In nature, biological materials are much more

Projektet går ut på att genom experimentella studier bygga upp en kunskap kring förhorning av komponenterna i träfibrer. Förhorning är ett fenomen där, i nuläget praktiskt sett irreversibla, processer i samband med torkning förändrar fibrernas svällning och flexibilitet och därmed bindningsförmåga. Bindningsförmågan till andra fibrer har stor inverkan på hur starka fibernätverk kan skapas och

Paper/wood-based materials suffer from poor barrier and moisture-sensitive properties (left figure). By learning how nature (plants/fruits) create moisture and gas barriers, we have developed crosslinked barrier biopolyesters (representing the cutin layer in plants) with also a process that yields a rough wax-like outer layer, similar to what is observed in plants, giving high surface hydrophobicity

The aim of the project is to gain a deeper fundamental understanding of how the classical structural factors and unique morphology of lignin affects the interaction between lignin and lignin-based materials and its surroundings. The affect of chemical structure and morphology on the material performance of lignin-based materials will be investigated along with the behavior

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,
