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).

Tribocorrosion performance of cellulose bio-base hydraulics fluids and their application in wave energy converters. 

Offshore wave energy converters (WECs) rely on different mechanical sub-systems such as hydraulic cylinders, joints, hinges, cables, gears and bearings to convert and transmit the kinematic energy transported by the waves and tides into mechanical usable energy. In order to comply with the increasing environmental regulations, and protect the mechanical moving components exposed to the

Magnetic nanopaper

This project is focused on production and development of magnetic nanopaper with ferrimagnetic properties. Cellulose nanofibrils (CNFs) are used as a stiff and strong matrix of natural origin, while ferrimagnatic nanoparticles of SrFe12O19 are added to bring in the functionality. Nanopaper is prepared by spray coating technique which is simple to handle and to upscale.

Fundamentals of nanoscale assembly of cellulose nanofiber

I am interested in fundamentals of cellulose nanofibers (CNF) and cellulose nanocrystals (CNC) in dilute, semi-dilute, and crowded environment. Specifically, for CNFs, semi-flexibility of fibers and its effect on nano-scale dynamics is a key aspect of my project. At the moment, combining simulations with experiments (X-ray photon correlation spectroscopy) is the strategy to proceed the

Hybrid Glycoproteins from Wheat Bran as Platform Materials

Vetekli är det yttre skiktet som omger kornens frövita och utgör den huvudsakliga biprodukten från vetemalningsprocessen och står för cirka 300 000 ton per år i Sverige. Vetekli används för närvarande nästan uteslutande industriellt som djurfoder på grund av lågt organoleptiskt värde och näringsvärde för mänsklig konsumtion. Vetekli innehåller emellertid en stor andel värdefulla biomolekyler

Structural Modification Softwood Pulp Cell Wall Under Extreme Pressure Conditions 

The ability to modify the structure of the wood-pulp fibre cell wall structure is an attractive means to obtain increased accessibility to the fibre interior and enable functionalization such as controlled drug delivery, interpenetrated networks, and selective removal of metal ions from aqueous mixtures just to mention a few examples. By changing the physical state

Mechanical behavior of all-lignocellulose composites 

In this study, we investigated property differences and failure mechanisms of hot-pressed, binder-free wood fiber composites. Random-in-plane microfibrillated lignocellulose (MFLC) composites showed better mechanical properties than microscale wood fibers WF due to stronger strain-hardening from lower porosity and better interfibrillar adhesion, provided by the intrinsic lignin-hemicellulose binder. Axially oriented wood fiber composites (O-WF) reached comparable

Preparation and use of lignocellulose nanomaterials in energy storage devices

Cellulose nanomaterials (CNs) obtained from fully-bleached (lignin-free) chemical fibers, such as cellulose nanoparticles (CNPs), cellulose nanofibers (CNFs), microfibrillated cellulose (MFC) have been a topic of extensive research during last decades since they constitute a biodegradable, renewable and naturally abundant resource with an important scientific and technological potential. However, the bleaching process is an energy-intensive process
