Macro- and microscopic deformability of fiber networks made from softwood fibres

Holmen is a major Swedish producer of paper and board products. Most of these products are based on softwood fibres. During converting of the products, they are plastically deformed in folding, creasing or embossing operations. This deformation occurs both in a macro and microscale. It is therefore important to understand the influence of the raw […]

Cavitation Fibrillation of Cellulose Fibres (CaFiCeFi)

The project is of explorative nature and aims on mapping the destructive nature of cavitation on cellulose fibres. Neither cavitation nor the dispersion of cellulose fibres in its constituents (cellulose fibrils for dissolving pulp fibres) is fully understood. The project objective is to guide whether cavitation is a mean for efficient and dedicated fibrillation at

Flow assisted assembly of biocomposite filaments based on Cellulose Nanofibrills (CNF)

The fundamental facet of this project is to design and fabricate functional composite filaments based on CNF and polymers. The aim is to prepare filaments  with superior mechanical properties and/or advanced functions. In this project, we are going to control the interaction between individual CNFs during flow assisted assembly using different heterofunctional polymers. The project is

Transparenta, cellulosabaserade förpackningsmaterial med goda barriäregenskaper

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

Lignin nanoparticles

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

The effect of compaction parameters on the properties of high-deformable paper

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

Karakterisering och kvantifiering av deformations- och skademekanismer i kartong under komplexa belastningsfall

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.

Develop contact-active antibacterial approaches on bio-based materials using LbL technique and their antibacterial mechanisms

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,
