11. Preparation and long-term performance of poly(ethylene-co-butyl acrylate) nanocomposites and polyethylene
Sammanfattning : The current study discusses the preparation and long-term performance of polymer composites used for various purposes under different ageing conditions.The first part deals with the preparation and characterization of polymer nanocomposites based on poly(ethylene-co-butyl acrylate) (EBA–13 and EBA–28 with 13 and 28 wt % butyl acrylate, respectively) and 2–12 wt % (0.

12. Molecular and epidemiological studies on eyes with pseudoexfoliation syndrome
Sammanfattning : Pseudoexfoliation (PEX) syndrome is an age-related condition characterized by the production and accumulation of extracellular fibrillary material in the anterior segment of the eye. PEX predisposes for several pathological conditions, such as glaucoma and complications during and after cataract surgery. LÄS MER
13. Analytical method development for ultra-trace determination of human pharmaceuticals in aqueous samples. Assessing the performance of a sewage treatment plant
Sammanfattning : Research focus in environmental pollution has recently been extended from more classical environmental pollutants such as PCBs or pesticides to pharmaceuticals and steroid hormones, which are designed to be biologically active and enter the environment primarily through regular domestic use. Consequently, it is important to monitor these substances concentrations in the effluents of sewage treatment plants (STPs) and in the environment in order to evaluate their associated risks. LÄS MER
14. Molecular dynamics and aggregation behaviour in aqueous polymer-drug model systems
Sammanfattning : Pharmaceutical formulations often contain polymers used as binders, swelling agents, etc., to give the formulation mechanical stability or specific drug release features. Many drug substances, as well as polymers, are amphiphilic which will give an associative polymer-drug interaction, affecting the dissolution rate and drug release. LÄS MER
15. Molecularly Imprinted Solid-Phase Extraction and Liquid Chromatography for Biological Samples
Sammanfattning : This thesis focuses on the use of molecularly imprinted polymers as selective sorbents for solid-phase extraction (MISPE). The MISPE methods developed were mainly intended for use with biological samples, such as human urine and blood plasma. LÄS MER
