1. Micro-mechanical mechanisms for deformation in polymer-material structures
Abstract : In this thesis, the focus has been on micro-mechanical mechanisms in polymer-based materials and structures. The first part of the thesis treats length-scale effects on polymer materials. Experiments have showed that the smaller the specimen, the stronger is the material. READ MORE

2. Experimental validation and numerical upscaling of linear network models for simulation of paper
Abstract : Paper modeling results in complex geometries that lead to enormous numerical problems. The complexity lies in the material's microstructure. Individual paper fibers must be considered for useful material simulations in paper development, where wood composition and other fiber-based parameters are essential. READ MORE

3. Antimicrobial materials from cellulose using environmentally friendly techniques
Abstract : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.

4. Biotic Ligand model : A tool for risk assessment of metals in Scandinavian fresh waters?
Abstract : Products from iron and copper mining are among Sweden’s top exports. However, as the metals are excavated, they often end up in the aquatic environment where they can cause toxicity. READ MORE

5. Particle Methods for Modelling Granular Material Flow
Abstract : Granular materials are very abundant in nature and are often used in industry, wherethe dynamics of granular material ow is of relevance in many processes. There arestrong economic and environmental incentives for increased eciency in handling andtransporting granular materials. READ MORE
