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. Analyzing the properties and biosynthesis of β-glucans from Gluconacetobacter and poplar
Sammanfattning : Glucans are polysaccharides integral to many materials and biological functions. Under the umbrella of Biomime, the Swedish Center for Biomimetic Fiber Engineering, this work has aimed to improve basic understanding of the biosynthesis of such glucans. LÄS MER
3. Cellulose-water interaction: a spectroscopic study
Sammanfattning : The human society of today has a significantly negative impact on the environment and needs to change its way of living towards a more sustainable path if to continue to live on a healthy planet. One path is believed to be an increased usage of naturally degradable and renewable raw materials and, therefore, attention has been focused on the highly abundant biopolymer cellulose. LÄS MER
