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, […]

Atomistic understanding of biomass interaction with hydrotreating catalysts 

The development of catalysts to upgrade renewable feedstocks is vital for a sustainable future. Alternative feedstocks typically differ in chemical composition compared to fossil-based feedstocks and to further develop catalytic materials that enable efficient and environmentally friendly chemical processes, it is necessary to understand the functional mechanisms of these materials in detail.The high oxygen content

Defibrillation of cellulosic substrates by novel bio-based ionic liquids 

New bio-based ionic liquids were developed as a greener and simple pathway for the activation of cellulosic substrates compatible with chemical modification (such as in situ polymerization). Preliminary experiments showed that these ionic liquids promote swelling/dispersing/defibrillation/partial dissolution of cellulose while retaining cellulose I crystalline structure after regeneration (full dissolution is not achieved). To get a

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

Molecular Basis of the Interactions and Recalcitrance of Lignocellulosic Biomass

Lignocellulosic biomass represents the main renewable resource from the biosphere for the production of biofuels, platform chemicals and bio-based materials. Lignocellulose consists of a complex polymeric network of cellulose microfibrils embedded in a matrix of hemicelluloses, pectins, and lignins with exquisite organization from the nano- to the microscale. However, the heterogeneity of the lignocellulose polymeric

Native cellulose’s interplay in materials and dispersions (CELLO)

This project supported by the Swedish Research Council (Vetenskapsrådet) focus on native cellulose´s interplay in materials and dispersions. The overall aim is to study and explain the intra- and intermolecular interactions of cellulose which occur during dissolution, in dispersions and in the regeneration of novel nanobiocomposite materials.

Structural characterization of cellulose and wood using electron microscopy and elecron diffraction

Cellulose is an essential constituent in the architecture of plants, where it contributes with extraordinary properties in terms of strength and stiffness. The aim of this project is to enable the development of new materials based on wood and cellulose, through the generation of new understanding regarding its structure all the way from the meso-scale

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.

Valorization of lignocellulosic biomass for non-fossil chemicals and fuels using photolysis based on LED

Sawdust, a valuable lignocellulosic biomass, is today considered waste and burnt to generate heat. Depending on the sawing process, sawdust might be up to 50% of the timber. An energy efficient valorization of lignocellulosic waste into non-fossil chemicals and fuels minimizes the CO2 footprint and contributes to a sustainable production. A major challenge is to
