From molecular interactions to macroscopic properties

The objective of this research project is to develop a deeper understanding on how chemicals can influence the dry strength of biocomposites, in our case board and tissue. The following parameters will be considered: -Influence of chemistry (mainly polyelectrolytes, PE) on bond and network strength -Influence of PE configuration and loading (charge) on bond and […]

Durable water-, oil- and soil repellent wood for outdoor applications via smart surface modification

Syftet med detta projekt är att förbättra hållbarheten utomhus av trä och biokompositmaterial för fasadmaterial samt utemöbler med hjälp av robust ytmodifiering som avvisar vatten, oljor och smuts. Vår nya idé bygger på användning av hållbara komponenter och skalbara processer. Vetenskapliga och tekniska mål är att formulera en halvtransparent beläggning för trä för att skydda

Inverse modelling of nanofibril dynamics in flowing systems

Design, scale-up and optimisation of flow systems for production of nanostructured assemblies is critical if the potential of many nanotechnologies is to be realised. Computer simulations of the flow and material structure will, of course, play an important role in this work. However, the behaviour of nanoscale building blocks (such as nanofibrils) cannot be simulated

Characterization of turbulent flows of non-Newtonian fluids with magnetic resonance flow imaging

The project “Characterization of turbulent flows of non-Newtonian fluids with magnetic resonance flow imaging” will provide critical knowledge necessary to provide accurate models for design, prediction and optimisation of processes in which non-Newtonian (and often multiphase) flows occur. The particular aspect that will be enabled is detailed comparison of flow data from experiments on opaque

High barriers for wood-based materials

 Nature-inspired high barrier materials from wood components for wood-based materials. Objectives Scientific: Investigate how the different components in a fruit/plant cuticle contribute to very high barrier properties (wax/lipid, crosslinked polyester and polysaccharides). Why are they assembled together the whey they are? Are there synergy effects? Can we go even beyond Natures high barriers by introducing

Structure and Properties of Hemicelluloses

Hemicelluloses represent one of the largest natural resources on Earth. They occur together with cellulose in plant cell walls and the exact structure varies between different types of plants. However, generally they are heteropolysaccharides that are branched and often also acetylated and methylated. The biological background for the structural heterogeneity of hemicellulose is unclear. Hemicelluloses

Green wood  adhesives based on side-streams from the pulp industry

In this project we propose to explore the use of side-streams originating from the pulp industry as adhesive binders for wood-based materials. The proposed project, aiming at developing novel, formaldehyde-free, adhesives from renewable resources, brings together experts in polymer/adhesive/wood chemistry with experts on forest/wood products and has the ability to gain novel, fundamental knowledge while
