16. Synthesis and Characterization of Sec-Packings Based on Trimethylolpropane Trimethacrylate
Sammanfattning : Suspension and bulk polymerization of trimethylolpropane trimethacrylate (TRIM) and copolymerization of TRIM with methyl methacrylate (MMA) resulted in porous, hydrophobic, and chemically crosslinked networks. Copolymerization of TRIM with acrylamide (AA) and with N,N'-methylene-bis-acrylamide (bis-AA) resulted in hydrophilic gels. LÄS MER
17. Synthesis and Characterization of Functional Polymers Based on Trimethylolpropane Trimethacrylate and Glycidyl Methacrylate
Sammanfattning : Copolymers of trimethylolpropane trimethacrylate (TRIM) and glycidyl methacrylate (GMA) were prepared with various monomer-to-solvent ratios, GMA to TRIM ratios and with various types of porogens. These parameters affected the inner morphology of the polymers and various pore surface areas (100-500 m2/g) and pore size distributions were obtained. LÄS MER
18. Protected Lignin Biorefining: Fundamental Insights on Lignin Reactivity
Sammanfattning : The potential to utilize lignin, which constitutes as much as 15-30% of the biomass, needs further evaluation. In the transition towards a bioeconomy, lignin has the potential to replace fossil-based phenols. Attempts to valorize the available technical lignins are ongoing; however, that lignin suffers from molecular heterogeneity. LÄS MER
19. Purification and biodistribution of extracellular vesicles
Sammanfattning : Extracellular vesicles (EVs) are nano-sized vesicles that contain bioactive lipids, RNAs and proteins, which can be transferred to recipient cells. EVs are important for physiological as well as pathological processes, such as coagulation and immune homeostasis, aiding cancer metastasis and spread of infectious diseases. LÄS MER
20. Isolation and characterization of lipid-associated and neurosecretory polypeptides
Sammanfattning : Lipid-interacting proteins play important roles in all living organisms. This thesis focuses on isolation and characterization of an enzyme in the triacylglycerol biosynthesis (phosphatidic acid phosphatase, PAP), hydrophobic polypeptides in bile, and polypeptides in cerebrospinal fluid.
