Sammanfattning : In the lead of developing new biomaterials from plant sources it is of importance to be able to control and vary the properties, such as flexibility, strength, and hygroscopicity of the final material. These properties are highly directed by the interactions between constituents on a molecular level. LÄS MER
Sammanfattning : In this thesis solid-state NMR and NMR cryoporometry were used to gain information of the structure of cellulose. Measurements were conducted on both native and regenerated cellulose, exposed to a range of different treatments. LÄS MER
3. Investigation of microstructure and porosity of columnar yttria-stabilized zirconia coatings produced by axial suspension plasma spraying
Sammanfattning : Ceramic topcoats provide thermal barrier coatings (TBCs) with its heat insulating properties. The heat transfer is primarily occurring by conduction through the bulk material, therefore features such as interfaces, pores and grain boundaries are essential for thermal insulation as they act as scattering sites.
