11. Structural chemistry of halocuprate (I) complexes as studied by mass spectrometry and molecular modelling
Sammanfattning : .... LÄS MER
12. Controlling Polylactide Degradation through Stereocomplexation and Lactic Acid Based Additives
Sammanfattning : The successful use of degradable materials in new applications depends on our ability to control the degradation process. A number of aspects need to be evaluated including degradation rate, the onset of degradation and the nature, formation and release of degradation products. LÄS MER
13. Novel clean-up, concentration and laser desorption/ionization strategies for mass spectrometry
Sammanfattning : Despite valuable advantages of mass spectrometry (MS) techniques they still have drawbacks that need to be overcome, notably their sensitivity to various kinds of interfering substances and associated difficulties involved in detecting signals from analytes present in trace quantities. Thus, high quality analytical data could be acquired by improving sample pre-treatment techniques and/or ionization methods to increase ionization yields and/or avoid the generation of unwanted ions.

14. Resin acids in commercial products and the work environment of Swedish wood pellets production : Analytical methodology, occurrence and exposure
Sammanfattning : The aims of the work this thesis is based upon were to develop convenient analytical procedures for determining resin acids in biological and environmental matrices, and apply them to enhance understanding of the occurrence, exposure to and uptake by exposed individuals of resin acids. Particular focus has been on the workplace environment of the Swedish wood pellets industry. LÄS MER
