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.
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 […]
Characterization of water transport in lignocellulosic systems
The aim of the doctoral project is to understand water transport phenomena in lignocellulosic systems better. The focus thereby lies on the characterization of cellulosic dispersions as well as wood-based materials employing state-of-the-art techniques such as nuclear magnetic resonance spectroscopy (NMR), environmental scanning electron microscopy (ESEM) neutron scattering as well as magnetic resonance imaging (MRI).
Catalytic functionalization of lignin
In this project we functionalize lignin using catalysts to form functional materials suitable for crosslinking to thermosets and/or composite materials.
HEALIX
This project is about development of novel wound dressing materials and we are making cellulose nanofiber hydrogels from wood as raw material.
Unbleached Kraft fibers for CNF and thermoplastic biocomposites
Unbleached Kraft fibers have been used to prepare lignin-containing CNF with interesting characteristics. The fibers and fibrils will be used in thermoplastic biocomposites, and structure-property relationships will be investigated.
Production of new high-performance CNF biocomposites (Cellulose nano-composites)
The aim is to develop new methods for large-scale melt processing of thermoplastic composites reinforced with high content of cellulose nano-fibrils. The goal is a thermoplastic process capable of mixing and shaping thermoplastic compositions reinforced with 30 % or more nano-cellulose, obtaining a functional composite stiffness at least 10 times of the polymer matrix. Alternatively, […]
Separation av oligomer hemicellulosa från koklut
Projektets huvudsakliga mål är att fraktionera högmolekylär hemicellulosa från sulfitlut. Processen som har utveklats inom projektet bygger på en initial membranfiltrering för att höja hemicellulosakoncentrationen. Hemicellulosan fraktioneras därefter selektivt från lignosulfonaterna genom fällning med alkoholer eller ketoner som sedan kan återvinnas. Hemicellulosan från projektet har testats i ett antal olika applicationer, bl.a. för att producera […]
0-3D Production of power papers
In 0-3D, we explore process protocols and manufacturing techniques for products based on electro-functionalized cellulose and cellulose nanofibrils (CNF) at large scale and volumes – Production of Power Papers. Bulky cellulose and CNF structures are excellent as the 3D scaffold for electro-active nanoparticles (0D), nano-fibers (1D) and coaxial coatings (2D) in order to scale-up high-performing […]
