1. Crystallinity and Morphology of Starch Polymers in Films
Abstract : Starch is a renewable material that can be converted into biodegradable plastic products, or films with excellent oxygen barrier properties. Films of potato starch, amylose, amylopectin and blends thereof were made by solution casting. READ MORE

2. The influence of crystallinity on the properties of carbon nanotubes
Abstract : Carbon nanotubes have been advertised as a material with quite extraordinary properties, both mechanically and electrically. The truth is that carbon nanotubes is not one material, but several different. READ MORE

3. Spray drying of particles intended for inhalation - Investigation of significant process variables and product characteristics, with focus on degradation and solid state properties
Abstract : The interest in spray drying for production of inhalable particles has grown considerably since the late 1980s. However, which process variables that control degradation and the solid state properties have not been subject to extensive research. This thesis deals with how important characteristics of inhalation particles can be controlled, i.e. READ MORE

4. On the Dielectric Losses of Polyethylene at Medium and High Frequencies
Abstract : AbstractAs mobile communication moves from 3G to 4G, the bandwidth used will be extended from 2 GHz to 5 GHz. The propagation loss is related to the 2.6:th power of frequency, thus a large increase in power consumption may be expected. READ MORE

5. Solid state characterisation and compaction behaviour of pharmaceutical materials
Abstract : In this thesis, factors important in tableting operations and for tablet properties have been studied and characterised by different spectroscopic techniques as well as by some more conventionally used particle characterisation techniques. The spectroscopic techniques solid-state NMR, FT-IR and NIR spectroscopy, proved to be valuable tools in the estimation of particle and tablet properties, offering both specificity and sensitivity in the measurements.
