11. Topological excitations in field theory models of superconductivity and magnetism
Sammanfattning : Topological excitations are subjects of intensive studies in physics and mathematics. In solid-state and soft matter physics, topological excitations can largely determine the thermodynamic and electromagnetic properties of materials, while in high energy physics they were theorized as particles.

12. Modelling of Formation and Evolution of Defects and Precipitates in Fe-Cr Alloys of Reactor Relevance
Sammanfattning : Fe-Cr alloys form the basis of many industrially important steels. Due to their excellent resistance to radiation induced swelling, ferritic steels are expected to be used for critical structural components in advanced nuclear systems, such as fast breeder reactors, accelerator driven systems and fusion reactors.

13. Att ordna, från ordning till ordning. Yngre förskolebarns matematiserande
Sammanfattning : A starting point for this study was an interest based in my earlier experience that most of the youngest children’s mathematizing in everyday life was unspoken and unknown. The aim of this thesis is to contribute to the knowledge about how toddlers mathematize and develop mathematical knowledge and understanding through activities with concrete material. LÄS MER
14. Crystallization on the Mesoscale : Self-Assembly of Iron Oxide Nanocubes into Mesocrystals
Sammanfattning : Self-assembly of nanoparticles is a promising route to form complex, nanostructured materials with functional properties. Nanoparticle assemblies characterized by a crystallographic alignment of the nanoparticles on the atomic scale, i.e. mesocrystals, are commonly found in nature with outstanding functional and mechanical properties.

15. Chiral Liquid Crystalline Side-Chain Polymers. Design, Synthesis and Properties
Sammanfattning : The potential use of chiral liquid crystalline materials, low molar mass as well as polymers, in technical applications has been recognized for some decades now. A number of interesting phenomena based on the spontaneous ordering of the liquid crystal forming molecules are strong reasons for the research effort in this area. LÄS MER
