Development of a new rheometer system at MAX IV

Rheometry explores the relationship between forces and motion through (continuum) constitutive relations and suitably defined material functionsi. Rheometry is important for soft matter from two main reasonsii: (i) to investigate correlations between molecular structure and material behavior and (ii) to attempt the prediction of flow behavior in complex situations using material parameters determined in simple, […]

Simulation and modelling of wood-based advanced functional materials

In this project we perform multi-scale theoretical modelling of wood-based materials and devices ranging from the Molecular Dynamics and ab initio simulations on the atomistic level to the drift-diffusion device simulation on the system level to answer the fundamental questions concerning material structure, morphology, polymerization, porosity, ion diffusion, role of water, solvents and many others,

The use of bio-polymers in micro fluidic devices for biomedical applications

By combining the knowledge in the field of surface modification with bio-polymers such as cellulose with the knowledge in microfluidic devices for biomedical applications. We foresee a huge potential in creating new useful devices for future increased health. During the recent decade cellulose in the form of different types of nano cellulose have attracted a

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

The role of water availability in fungal degradation of lignocellulosic materials

We need to increase the use of lignocellulosic materials in all sectors in society, e.g., both as construction materials and as feedstock for the chemical industry. The possiblilty of such an increase is dependent on whether we can make construction materials more durable by eco-friendly methods, and the lignocellulosic feedstock easier to degrade in the

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
