1. In the confines of Cu(In,Ga)Se2 thin film solar cells with rear surface passivating oxide layers
Abstract : The material supply to build renewable energy conversion systems needs to be considered from both a cost and an energy security perspective. For Cu(In,Ga)Se2 (CIGS) thin film solar cells the use of indium in the absorber layer is most problematic. READ MORE

2. Structural studies of some bacterial polysaccharides and extension of a method for lipid A cleavage
Abstract : The focus of the work presented in this thesis has been to study the structures of the capsular polysaccharide from Serratia marcescens O14:K12, and the O-antigen polysaccharides from Hafnia alvei strain 10457 and Vibrio cholerae serogroup 037. Nuclear magnetic resonance (NMR) spectroscopy was the primary technique employed. S. READ MORE

3. Structures of some bacterial polysaccharides with focus on pneumococcal polysaccharides and their associated C-polysaccharide
Abstract : This thesis describes the chemical structures of the capsular polysaccharides from Streptococcus pneumoniae types 18B, 32F, and 32A. The structure of the pneumococcal common antigen, C-polysaccharide, from a non-capsulated pneumococcal strain, CSR SCS2, is described and the structure of the C-polysaccharide associated with pneumococcal types 18B, 32F, and 32A.

4. High-Temperature Microfluidics for Space Propulsion
Abstract : In this thesis, microfabrication methods and tools for analysis of heated cold-gas microthrusters are presented, with the aim of improving their reliability and performance. Cold-gas thrusters operate by accelerating pressurized gas through a nozzle. READ MORE

5. Characterization of Aeromonas, Enterobacteriaceae, Pseudomonas, Bacillus and Lactobacillus spontaneously growing to high numbers in milk, minced meat, fish or cheese
Abstract : The spoilage flora of refrigerated raw and pasteurized milk was classified and identified by numerical phenotypic analysis. Isolations of bacteria were made at a defined spoilage stage, when the total aerobic count was 106-107 cfu per ml. The secondary flora of ripened Swedish and Norwegian cheeses was investigated by numerical analysis. READ MORE
