1. Chromatography and extraction techniques for new evaluation methods of polyolefins long-term performance
Sammanfattning : Chromatography and extraction techniques, and also chemiluminescence have been utilized to develop new rapid and informative tools in the evaluation of long-term properties and environmental effects of polymeric materials. Methods were developed for classification of materials and for early and rapid degradation detection. LÄS MER
2. Clinical and Immunological Studies in Chronic Myeloid Leukaemia
Sammanfattning : Chronic myeloid leukaemia (CML) is characterised by the constitutively active tyrosine kinase BCR-ABL. Standard treatment with tyrosine kinase inhibitors (TKI) in the chronic phase (CP) of CML conveys excellent long-term prognosis but is associated with side effects and costs. LÄS MER
3. Determination of Persistent Organic Pollutants in Solid Environmental Samples Using Accelerated Solvent Extraction and Supercritical Fluid Extraction. Exhaustive extraction and sorption/desorption studies of PCBs
Sammanfattning : Human activity is constantly causing environmental problems due to production and release of numerous chemicals. A group of compounds of special concern is persistent organic pollutants (POP). These toxic, lipophilic chemicals have a high chemical and biological stability, and tend to accumulate in the lipid phase of living organisms. LÄS MER
4. Organic Synthesis in Nonionic Microemulsions
Sammanfattning : The aim of this work has been to explore the use of microemulsions as reaction media for organic synthesis. Another important aim has been to improve the understanding of the reaction kinetics and the mechanism of the reaction in this type of surfactant system. LÄS MER
5. Capillary electroseparations with mass spectrometric detection Nanoparticle-based continuous full filling and applications for complex sample matrices
Sammanfattning : One of the major challenges in analytical chemistry is to find techniques and methods for determinations of low abundance compounds in complex sample matrices. This thesis describes the development of new miniaturised analytical techniques comprising capillary electroseparation combined with mass spectrometric detection. LÄS MER
