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, […]
Biomass-derived hybrid materials and composites
The project aim is the design and engineering of biomass-derived composites to substitute petroleum-based materials.
Synthesis of chemicals from biomass residues for energy storage applications
The aim of my project is to create a scientific base for sustainable processes for using the waste-residue streams from pulp production more efficiently.
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 […]
Microscopic computed tomography aided finite element modelling of wood
Laboratory X-ray tube-based microscopic computed tomography (XµCT) aided finite element (FE) modelling considers XµCT data to characterize key engineering properties needed for modelling of material behavior. The method includes steps such as XµCT scanning, segmentation, meshing, and fiber reconstruction and can be supported by techniques such as digital image correlation and digital volume correlation. At […]
Multi scale modeling of the delignification kinetics during kraft cooking
The kraft process is today the dominant industrial technology for the production of pulp from wood.In this process, wood chips are boiled with chemicals in order to dissolve lignin, hemicellulose andextractives. The process itself contains several complex mass transport mechanisms, where thechemicals are to be transported into the wood chip and then further into the […]
Material properties of wooden material: scale effect
The use of wood as a building material because of its efficiency, sustainability, and durability is increasing. Wood is a renewable resource, it has low carbon impact and low embodied energy. The amount of energy needed for producing wood products is much less than comparable products made from other materials. In spite of its common […]
