Diffusion and damage during delignification of wood biomass (D4mass)

Delignification is a crucial process in the pulp industry that separates lignin and cellulose, the two biobased raw materials with enormous potential. During this process, the removal of lignin through diffusion is coupled with the accumulation of damage in cell walls, causing cracks and changing the trajectory of diffusion. However, a mechanistic understanding and a […]

Tailored Lignin-Derived Materials for Remediation of Water, Soil, and Sediments

This project aims to develop value-added lignin-derived materials and explore their potential in mitigating pollution from both emerging and regulated contaminants, including PFAS and other micropollutants. The target materials include lignin-derived carbons and biochars with tailored surfaces, modified lignins, lignin-based composites, and 3-D materials.

A multiscale modelling approach aided by X-ray techniques to deepen the understanding of the effect of climate change on the hygromechanical behaviour of wood

Climate change has shown to alter the mechanical properties of wood. This suggest an alteration of the hygromechanical behaviour, behaviour that by itself is not fully elucidated yet. The deeper understanding of the hygromechanics of wood is important in the correct prediction and interpretation of drying and long-term behaviour of this material. In this light,

Theoretical study of lignin swelling in atomistic details

In this project vi use molecular dynamics (MD) simulations to investigate hygroscopic properties of various lignins. Our hope is that structure and dynamics on the atomistic level of details will complement existing macromechanical models. The goal is to test existing atomistic models of lignin subject to its interactions with water. The output of the project
