Structure-property relationships in lignin-based porous carbon materials for water purification

Good water quality is essential to human health, social and economic development, as well as the ecosystem. Industrialization and urbanization, together with the explosive population growth, have caused a great challenge for maintaining safe and clean water resources. Among many strategic and research activities for water protection, a direct approach is to develop biobased porous …

Cellulose-based organic solar cells via spray deposition

In this project, we use spray deposition to fabricate cellulose-based, flexible organic solar cells. We use TEMPO-cellulose nanofibrils (TEMPO-CNF) as sustainable substrate material, flexible silver- or copper-nanowires (AgNW-/CuNW) as electrode material, conductive poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) as electron blocking layer, and a mixture of poly(3 hexylthiophene) (P3HT) and [6,6]-phenyl C61 butyric acid methylester (PCBM) as …

Upgrading recycled thermoplastics using cellulose oxalate for a more sustainable future 

The absolute majority of plastic used today are fossil-based thermoplastics such as polypropylene and polyethylene. To an extent these plastics are recycled through mechanical recycling but the recycled plastic is mainly used for low-end, low quality products. This is due to decreased mechanical properties and due to that the recycled plastic often obtains a black …

Sustainable biocomposites

My research is about molded wood fibers, nanocellulose films, and polymer matrix biocomposites for desired properties, particularly mechanical performance within a sustainable development framework.Understanding the process, structure, and properties of hot-pressed biocomposites is the primary research question.

Synthesis, Characterization, Structure and Properties of Novel Non-Isocyanate Polyurethanes

To prepare novel biocomposites between cellulose (nano)fillers (nanofibers and nanocrystals) and NIPU thanks to their propensity to set up hydrogen bonding and interfacial covalent cross-linking with them.ESR9: To design biocomposites from novel waterborne or solvent-free functional NIPU polymers, where interface aspects and dispersion considerations are emphasized in order to achieve desired properties and processing characteristics.

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 …

WWSC2.0 Lignin Materials

We investigate how lignin-derived carbon materials can be tailored for use in electronic applications, primarily as electrodes in electrochemical capacitors.

Modeling, processing and optimization of highly-filled polymer wood fiber composites 

Biocomposites are a critical ingredient in the context of overarching societal efforts to increase the use of renewable materials. Therefore, the use of polymer with natural fiber reinforcements is expected to increase significantly. A current drive for polymer biocomposites is to maximize the use of renewable content in mass production systems. However, the full potential …
