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

TREESEARCH

In this project we functionalize lignin using catalysts to form functional materials suitable for crosslinking to thermosets and/or composite materials.

Unbleached Kraft fibers for CNF and thermoplastic biocomposites

TREESEARCH

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)

Anastasia Riazanova

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

TREESEARCH

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

Anastasia Riazanova

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
