1. Computer Simulations of Polymer Gels : Structure, Dynamics, and Deformation
Sammanfattning : This thesis presents the results of computer simulation studies of the structure, dynamics, and deformation of cross-linked polymer gels. Obtaining a fundamental understanding of the interrelation between the detailed structure and the properties of polymer gels is a challenge and a key issue towards designing materials for specific purposes.

2. Deformation of cellulose allomorphs studied by molecular dynamics
Sammanfattning : Cellulose-based materials draw their good mechanical properties from the cellu-lose crystal. Improved understanding of crystal properties could lead to a wider range of applications for cellulose-based materials, Cellulose crystals show high axial Youngs modulus. LÄS MER
3. Plasticization of Biobased Polymers: A Combined Experimental and Simulation Approach
Sammanfattning : The field of bio-based plastics has developed significantly in recent decades and there is an increasing demand for industries to shift from petrochemical to biobased polymers. Biobased polymers offer competitive properties, and in many cases have advantages in terms of cost. LÄS MER
4. Polymer and Protein Physics : Simulations of Interactions and Dynamics
Sammanfattning : Proteins can, without any exaggeration, be called the "building blocks of life". Their physical properties depend not only on the chemical structure but also on their geometric shape. In this thesis, I investigate protein geometry using several different methods.We start with a coarse-graining model to study the general behavior of polymers. LÄS MER
5. Dynamics of Disordered Materials in Confined Geometries
Sammanfattning : This thesis is concerned with effects of geometrical confinement on dynamics in disordered materials in the nanoscopic range. Of particular interest is the dynamics around the liquid to glass transition. Two systems have been investigated: thin polymer films and polymer gels. LÄS MER
