Elucidating the mechanisms affecting diffusion of retention aid in flocculated fibre suspensions

The project is about the development of new knowledge regarding the transport of chemical retention aids and fines in flocculated pulp suspensions. Specifically, we have developed a method to study the diffusion of polyelectrolytes in model fiber flocs and to quantify the transport on the micrometre to millimetre scale.

Application of functionalised lignin nanoparticles as Pickering emulsifier in paper-coating

This project focuses on the chemical modification of lignin to impart antibacterial and flame-retardant properties. By leveraging the advantages of nanoscale structuring, the modified lignin nanoparticles are expected to act as efficient emulsifiers in oil–water systems. Ultimately, this approach aims to generate a multifunctional, lignin-derived material from a waste resource.
