26. Oxidative dissolution of doped UO2 and H2O2 reactivity towards oxide surfaces : A kinetic and mechanistic study
Sammanfattning : Oxidative dissolution of std. UO2 and UO2 doped with Cr2O3 and Al2O3, i.e. ADOPT, induced by H2O2 and γ radiation has been the main focus in this licentiate thesis. LÄS MER
27. Hybrid nanoadsorbents for extraction and separation of rare earth elements in solution
Sammanfattning : Rare Earth Elements (REE) are a group of 17 metals (those known as lanthanides plus Ytrium and Scandium), which are increasingly important for many emerging modern applications. This work is focused on the development of high performance new magnetic silica based nanoadsorbents which are surface functionalized for efficient uptake and separation of REE in solution. LÄS MER
28. Engineering of small IgG binding domains for antibody labelling and purification
Sammanfattning : In protein engineering, rational design and selection from combinatorial libraries are methods used to develop proteins with new or improved features. A very important protein for the biological sciences is the antibody that is used as a detecting agent in numerous laboratory assays. LÄS MER
29. Giant Dipole Resonances as Probes of Local Environment in Molecules, Clusters and Solidsl
Sammanfattning : In this thesis, I study effects of the local environment on the giant dipole resonances (GDR) in lanthanides and actinides. The effects of embedding in jellium, bonding in small molecules and incorporation into different fullerene systems are studied. LÄS MER
30. On the Diluent and Solvent Effects in Liquid-Liquid Extraction Systems based on Bis-triazine-bipyridine (BTBP) ligands
Sammanfattning : Used nuclear fuel is dangerous for mankind and her environment for a long time. If however, the minor actinides together with uranium and plutonium could be transmuted, i.e. transformed, into more shortlived or stable isotopes the volume of the waste could be significantly reduced together with a reduction in the radiotoxicity.
