1. Structural Elements in Native Celluloses
Sammanfattning : In this thesis, a schematic model for the structure ofaggregated cellulose I fibrils is proposed. The model consistsof a crystalline fibril core surrounded by less orderedcellulose forms. These cellulose forms are fibril surfacesaccessible to water, fibril surfaces inaccessible to water andpara-crystalline cellulose. LÄS MER
2. Amyloid β peptide: from monomer solubility to fibril structure
Sammanfattning : Alzheimer´s disease (AD) is the most common human neuro-degenerative disease characterized by the formation of cerebral plaques. Several are the amyloid-beta (Aβ) variants found in the brain of healthy individuals. LÄS MER
3. Orientation of elongated, macro and nano-sized particles in macroscopic flows
Sammanfattning : Non-spherical particles are present all around us, in biological, industrial and environmental processes. Making predictions of their impact on us and systems in our vicinity can make life better for everyone here on earth. LÄS MER
4. The application of single fibre fragmentation to spruce tracheids
Sammanfattning : .... LÄS MER
5. Local variability in chemical and physical properties of spruce wood fibers
Sammanfattning : Wood is well known to be a heterogeneous native materialwith large variations in its composite properties, includingvariations whose origins have not yet been completelyidentified. Traditionally, the macroscopic variations in woodhave received the most attention; for example, the variation indensity from the pith to the bark in trees. LÄS MER
