Sverige har som målsättning att bli en totalt biobaserad ekonomi från år 2050. Skogsindustrin, som är en nyckelaktör för ekonomisk utveckling i Sverige, kan här spela en central roll. Vid produktion av kemisk massa frigörs en polyfenolisk förening som kallas lignin. Den globala årliga produktionen av lignin från den dominerande processen för att producera massa […]

I mark och hav ansamlas på grund av mänsklig aktivitet stora mängder plaster, ofta från påsaroch förpackningar. I värsta fall tar det flera hundra år för naturen att bryta ner dessa plaster.För att åtgärda denna miljöförstöring räcker det alltså inte bara att vi blir bättre på att återvinnaoch slänga vårt plastskräp på rätt sätt, utan

To develop and characterize filaments for advanced applications, i.e. green smart textiles or conductive fibers. Use a flow-focusing setup and cellulose nanofibers as a main material for preparation of filaments with high mechanical performance. To understand the fundamentals behind alignment and particle organization. To study impact of hydrolysis and delignification of wood chips on their structure
The project is aimed for development and functionalization of nanoparticles (NPs) based on technical lignins. Due to natural origin of lignin and good biocompatibility, lignin NPs (LigNPs) can find application as targeted drug delivery vehicles for future implementation in biomedicine. Within the scope of this project, we aim to develop novel multifunctional lignin nanoparticles from

Nanocellulose in the form of fibrils (CNF) from wood is a new building-block for complex nanocomposites. Both the new materials and CNF itself are of major scientific and technical interest, with strong industrial potential. The use of colloidal systems makes it possible to mix CNF with for instance montmorillonite clay (MTM) or graphene oxide (GO)

This project addresses the challenges of producing high-deformable paper for 3D forming applications using the in-plane compaction process. Enabling 3D forming of advanced paper structures paves the way for complete elimination of plastic based packaging or partial replacement of plastic in multi-material packages, which aligns with current international strategies for a sustainable development of the

Projektets mål är karakterisering och kvantifiering av deformations- och skademekanismer i kartong under komplexa belastningsfall. Sådana är praktiskta viktiga vid konvertering av kartong i allmänhet, men speciellt betydelsefulla vid 3D-formning av geometriskt avancerade strukturer. För att nå målet ska experimentella 4D datortomografiundersökningar kombineras med matematisk modellering.
Layer-by-layer coating technique has been shown their considerable advantages including fast and mild process, flexibility and easy to scale up comes to the surface functionalizations. One of the most pronounced functionalities is the antimicrobial approach. We are aiming at developing non-complicated methods for antibacterial properties on different substrates mainly cellulose-based materials using alternative cationic polyelectrolytes,
The project focuses on synthetic pathways to modify lignin to introduce chemical groups suitable for cross-linking reactions and elaboration on the mechanical properties of the formed materials. The main focus is allylation, introducing an allyl ether functionallity selectively on phenols, and thiol-ene reactions for cross-linking of the thermoset resin. This is performed on technical lignin
