2. Impact of drying and heat treatment on physical properties and durability of solid wood
Sammanfattning : During drying and heat treatment, wood is exposed to a hygrothermal process during which wood properties are chemically and physically affected, resulting in responses on a microscopic as well as on a macroscopic level. The main objective of this thesis is to build knowledge on the interaction between the wood material properties and the drying and heat treatment process in terms of material responses. LÄS MER
3. The cell wall ultrastructure of wood fibres : effects of the chemical pulp fibre line
Sammanfattning : Knowledge of the ultrastructural arrangement within wood fibres is important for understanding the mechanical properties of the fibres themselves, as well as for understanding and controlling the ultrastructural changes that occur during pulp processing. The object of this work was to explore the use of atomic force microscopy (AFM) in studies of the cell wall ultrastructure and to see how this structure is affected in the kraft pulp fibre line.
