Phase separation of cellulose derivatives during extrusion – one way to enable the next generation drugs

The project aims to study the plasticisation of cellulose derivatives by water and active pharmaceutical ingredients. The project will use and develop scattering techniques and different mechanical, thermal and permeability characterisation techniques such as DMA/DMA+RH, DSC and oxygen permeability at different RH. The purpose is to better understand how cellulose derivatives interact with water as […]

Mass transport in wood components from processed woods(III-3)

TREESEARCH

Purpose of the project is to study mass transport of ionic liquids into wood pieces and fibers and consequent lignin and hemicellulose transport out from the pieces. Therefore, characterisation techniques to investigate the location of ionic liquids and lignin in the fiber structure are needed to be developed. Examples of such techniques are X-ray imaging,

Plasticization and partial depolymerization of lignocellulose-based materials

TREESEARCH

This project is a part of the competence center FibRe. This particular PhD student project aims to plasticize the lignin in the cell walls. The first part will be to extract lignin from wood and wheat straw, and to evaluate how different plasticizers affect the material properties. This will then be extrapolated to lignocellulose-based fibers.

Design for Circularity: Lignocellulosic based Thermoplastics – FibRe

TREESEARCH

Global warming is one of the largest threats ever to our planet which can completely alter our living conditions. Human contributions to emissions of green-house gases must decrease, and a drastically decreased use of fossil resources is a key step to achieve this. Daunting 320 million tons of plastics are annually produced in the world,

Mass transfer challenges in wood decomposition

TREESEARCH

Cellulose is the most abundant biopolymer. It can be extracted from the primary cell wall of green plants. The primary resource for production of cellulose is wood, where it is attached to other biopolymers such as hemicelluloses and Lignin. A challenging step in material biorefinery is separation of Lignin from cellulose, in which mass transport

Adsorption av funktionella polymerer tillcellulosa i blekningssteget – ett sätt att utöka fibrernas egenskaper

TREESEARCH

The purpose of this proposed project is to suggest new pathways for the adsorption reactions to cellulose fibers in the bleaching step in the kraft pulp process. The long-term aim is to develop a flexible knowledge platform that can be used for designing functionalized surfaces of the cellulose fibers in the bleaching step, using by

Design av fuktokänsliga biobaserade syrgasbarriärer genom att systemtiskt korrelera biopolymernas molekylstrukturna till barriärfunktionen

Anastasia Riazanova

The total Swedish export income from packaging and forest-based products is more than 11%. Our forest is a renewable resource that can be used to produce and develop more sustainable packaging materials with decreased climate stress compared to today’s fossil ones or aluminum foil. But, the replacement of fossil based materials with bio-based counterparts is
