MYCOSITE-MYCelium based compOSITE, towards a truly sustainable biomaterial 

Mycelium-based biocomposites are an emerging category of materials exploiting the abundance of lignocellulosic waste generated yearly, such as wood by-products, waste fibers or residual stems/husks, and the natural growth of a living fungal organism. Fungi bring strength and cohesion to amorphous materials by producing microscopic filaments (called hyphae) that form the mycelium and lignocellulosic biomass […]

MYWOOD-MYcelium as tool for the valorization of WOOD by-products, from materials to enzymes 

Forestry biomass, the most abundant renewable resource on Earth, is an untapped source of energy and material. Biorefinery practices are still inefficiencies, leading to waste and reduced sustainability. This project proposes an integrated biorefinery approach, leveraging advanced fungal biotechnology to repurpose underutilized forestry biomass into innovative biobased materials and enzymes, while exploring the further biorefinery

Quantification of fungal damage in Scots pine round timber by X-ray CT imaging

The rising problem of pine forests experiencing various forms of damage, notably in young forests situated in northern Sweden, is a mounting cause for worry. The culprit behind this damage is Scots pine blister rust, Törskate (in Swedish), a fungus that specifically attacks the tree's trunk and branches. The primary goal of this project is

The bio-feedstock of tomorrow for controlled and reversible chemical modification on the macro and microfiber level 

Itaconic acid, a di-carboxylic acid produced from citric acid or fermentation of sugars, is predicted to become a valuable bio-based chemical for the future, making it interesting for applications in cellulose based functional materials. This project will investigate the tailored modification of Bleached Kraft Pulp (BKP) with itaconic derivatives. Since the reactivity to a large

Modelling of conductive polymer-redox polymer supercapacitors

The Laboratory of Organic Electronics is developing cellulose base conductive polymer-redox polymer supercapacitors for large scale energy storage. This project focus on the modelling of such systems by coupling a recently developed theoretical model for organic mixed electronic-ionic conductors with the redox chemistry of wood-based redox polymer for energy storage applications. The aim is to

Mass transport in wood components from processed woods(III-3)

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,

Wood modification towards hierarchical catalyst

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

Wood-based barriers for wood-based materials

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

Physical Structure and Interactions between Lignin and its Surroundings

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

Water based wood treatment

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,
