Advanced rheological characterization of cellulose based systems
Processing, e.g. extrusion, injection molding, typically involves rheologically complex materials in complex flow configurations. The deformation history therein experienced by materials is generally characterized by a series of shear, extensional, or a combination of the two deformations, at high isotopic pressures and temperatures. Therefore, a fundamental understanding of the material response in simple shear and […]
Simulation and modelling of wood-based advanced functional materials
In this project we perform multi-scale theoretical modelling of wood-based materials and devices ranging from the Molecular Dynamics and ab initio simulations on the atomistic level to the drift-diffusion device simulation on the system level to answer the fundamental questions concerning material structure, morphology, polymerization, porosity, ion diffusion, role of water, solvents and many others, […]
NMR as tool to study heterogeneity in biomass
In this project, the purpose is to implement solid-state NMR methods to obtain domain sizes in biopolymer composites and to determine molecular orientation distribution in anisotropic material. The ambition is to take advantage of recent methodological NMR development regarding spin diffusion and intrinsic chemical shielding tensor properties. The project is a part of WWSC
Functionalized cellulose structures from aqueous alkaline systems
Even though aqueous alkaline systems are among the most prominent and sustainable conversion media for cellulose (of particular importance for large scale processes) fundamental understanding of principal molecular interactions in these systems is still limited, especially of those stabilizing cellulose solutions in aqueous alkali. However, regardless of the nature of stabilizing interactions in these solutions, […]
Enzyme discovery and structure-function investigation of carbohydrate-active enzymes – new tools for biomass tailoring
The plant cell wall is a highly complex structure, and the main constituent of wood as a material. Microorganisms can break down essentially all parts of the cell wall with time, and their enzymatic strategies can today be utilized thanks to the advances in molecular biology and biochemistry. The enzymes can be used as highly […]
Fractionation of wood components using membrane filtration
Development of efficient separation processes are vital for the realisation of the biorefinery concept. Membrane filtration as a pressure driven operation has the potential of being a very energy efficient separation and fractionation method in this application. However one of the largest challenge when using membranes is fouling and these fouling problems can be expected […]
Fibre-based materials for next generation energy storage systems
In this project we will explore the possibilities given by fibre-based wood polymer materials for applications for high capacity batteries, for electromobility as well as grid energy storage. These materials offer routes for modification and tuning of chemistry, the morphology and processing to obtain e.g. tailored porosity and functionality. This tailoring is needed both on […]
High barriers for wood-based materials
Nature-inspired high barrier materials from wood components for wood-based materials. Objectives Scientific: Investigate how the different components in a fruit/plant cuticle contribute to very high barrier properties (wax/lipid, crosslinked polyester and polysaccharides). Why are they assembled together the whey they are? Are there synergy effects? Can we go even beyond Natures high barriers by introducing […]
Conductor patterns in wood and paper
This project is part of WWSC 2.0 at LiU. The project aims at investigating methods to modify cellulose-based materials such as paper to become electrically conductive, and moreover to do so in a spatially constrained way, in order to create conductor patterns. The long-term goal of the project is deriving 3D patterning and manufacturing techniques […]

This project is part of WWSC 2.0 at LiU. The project aims to functionalize pretreated wood chips with electroactive materials to achieve electronic functionality.
Investigation of membrane fouling during microfiltration of wood components
Development of efficient separation processes are crucial for the realisation of the biorefinery concept, which is important to enable the substitution of fossil raw materials for production of materials and chemicals. Membrane filtration as a pressure driven operation has the potential of being a very energy efficient separation method in this application. However one of […]
