A new sustainable route to polysaccharide hydrogel formation for medical and cosmetic applications

Hydrogels are an extremely versatile class of material, and have found relevance in cosmetic, medical, pharmaceutical, and industrial processes. A hydrogel has a low solid content, often comprising at least 90% water. Although hydrogels are increasingly used in cosmetics and drug manufacture, the production process is far from sustainable, relying on fossil-based polymers and chemical […]

Renewable High-Performance Materials from the Forest with Designed Degradation – Next Generation of Plastic (Re-Design Plastic)

Sustainable material design can alleviate the environmental burden related to material waste. Use of available and abundant resources, create materials that can be recycled, and final degradability in nature is central to achieve this. The overarching aim of the proposal is to holistically design new materials from cellulose fibers by; developing new sustainable modification strategies,

Study of the multiscale networks of hemicellulose hydrogels by scattering techniques

The aim of the project is to develop multifunctional soft materials (hydrogels) from hemicelluloses for biomedical and food applications. We combine chemo-enzymatic methods to modify the molecular structure of the hemicelluloses and to tailor their assembly and rheological properties. In this project we want to understand the assembly mechanisms that drive the gel formation upon

Biomassa från Salix för en biobaserad ekonomi

Målet med projektet är att studera alternativa användningsområden av biomassa från salix, t.ex. som råvara för produktion av biobränslen och av nya biokemikalier. Salix är en snabbväxande gröda med hög biomassaproduktion. För att förstå möjligheten att använda salix som råvara i olika processer behöver vi studera hela odlingssystemet hos salix inklusive både ovan- och underjordsprocesser.

Recyclable and Creep Resistant Polyethylene – through Transient Cellulose Networks

Plastics enhance almost every aspect of human life from food consumption to medical care and even energy production. However, the often superficial use of plastics means that a large fraction of this versatile class of materials is not recycled but, instead, burned for energy recovery, buried as waste in landfills, or worst case simply discarded

Fundamental understanding of the moisture uptake in modified wood

The use of wood and wood based materials in moist environments is limited because of these material’s susceptibility to decay fungi.  The durability thus needs to be improved, which can be achieved by chemical wood modification. The exact mechanisms behind the increased durability of modified wood is however not known, but the lowered moisture content is
