1. Crystallinity and Morphology of Starch Polymers in Films
Sammanfattning : 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. LÄS MER
2. The influence of crystallinity on the properties of carbon nanotubes
Sammanfattning : 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. LÄS MER
3. Spray drying of particles intended for inhalation - Investigation of significant process variables and product characteristics, with focus on degradation and solid state properties
Sammanfattning : 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. LÄS MER
4. On the Dielectric Losses of Polyethylene at Medium and High Frequencies
Sammanfattning : 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. LÄS MER
5. Cellulose processing in ionic liquid based solvents
Sammanfattning : As the most abundant polymer in nature, cellulose has an undisputed role among the raw materials to be used in a sustainable future. From its native form, in wood or straw, cellulose can be processed into products such as paper and board. LÄS MER
