11. Constitution, dynamics and structure of binary and ternary actinide complexes
Sammanfattning : Stoichiometry, ligand exchange reactions, coordinationgeometry and stability of complexes of type UO2LpFq(H2O)3-n(p= 12,q= 1-3), where L is one of the bidentate ligandspicolinate, oxalate, carbonate or acetate have beeninvestigated using single crystal X-ray diffraction, an arrayof19F-,13C-,17O- and1H-NMR techniques and potentiometric titration usingboth F-and H+selective electrodes. The experiments wereperformed in a 1. LÄS MER
12. Pulsed Field Gradient NMR Studies of Diffusion in Polymer Gels
Sammanfattning : Soft biomaterials, such as gels, play an important role in different kinds of products and applications, in particular in drug delivery systems, health care products, and food. Polymer gel's great ability to control mass transport is applied on e.g. the uptake of liquids in diapers. LÄS MER
13. New methods and reagents for small scale synthesis of phosphor organic compounds with focus on the phosphonic acids and their analogues
Sammanfattning : The development of a synthetic method of radiolabelled methylphosphono-fluoridates on a milligram scale is presented. The aim of this method is, besides affording high yield, to choose reaction pathways and reagents so that handling and transfer of labelled toxic substances is minimised, thereby reducing the risk of exposure as much as possible.

14. Defects in Zeolite Catalysts and Membranes
Sammanfattning : ZSM-5 is one of the most well-known zeolites. It has been synthesized for many different applications, including as catalyst for catalytic reactions and as a membrane in separation processes. The main goal of this thesis is to investigate and characterize the defects in crystal and film growth of ZSM-5 for modification purposes. LÄS MER
15. Tailoring Surface Properties of Bio-Fibers via Atom Transfer Radical Polymerization
Sammanfattning : The potential use of renewable, bio-based polymers in high-technological applications has attracted great interest due to increased environmental concern. Cellulose is the most abundant biopolymer resource in the world, and it has great potential to be modified to suit new application areas. LÄS MER
