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, […]

Design of biochar from residual streams – influence of fuel and process parameters on biochar properties for water and soil applications

Biochar can be used in many applications, including water treatment and soil improvement. The properties of biochar are affected by the conditions during production. In this project, the influence on the properties of the biochar at different process conditions is investigated through the gasification of residual streams from both the forestry and agricultural sectors. The

Processing of organosolv fractions for a functionalization and valorization in biobased materials

Optimization of organosolv wood fractioning is performed to obtain pulp containing cellulose, hemicellulose, andlow levels of lignin. The pulp is functionalized to achieve specific fibre properties, such as water stability. The functionalized fibres are evaluated in industrial partners’ products, i.e. biobased foams, to provide valuable feedback for optimization of the functionalization procedures based on industry

Multiscale carbonized lignin nanomaterials with tailored structure for high electrochemical capacitance

The project work focuses on the development of functional nanostructured carbon material with large specific surface area and derived from sustainable materials, mainly lignin. Approaches such as electrospinning, freeze-casting as well as 3D printing can be involved. The possible applications of the carbon material can be electrodes in high-performance energy storage devices, for example, supercapacitors.

KAW Biocomposites

Technical objective The project is focused on materials design of biocomposites which are semi-structural, recyclable and/or biodegradable. The term “semi-structural” needs to be defined. If 30wt% glass fiber/polypropylene is selected as the reference material for substitution, it would mean that the modulus should be > 6 GPa and the tensile strength > 85 MPa. In
