    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Oxidative dissolution; UO2; ADOPT; H2O2; Spent Nuclear Fuel.; Kemi; Chemistry;

    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

  2. 27. Hybrid nanoadsorbents for extraction and separation of rare earth elements in solution

    Författare :Elizabeth Polido Legaria; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    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

  3. 28. Engineering of small IgG binding domains for antibody labelling and purification

    Författare :Sara Kanje; Sophia Hober; Cecília Roque; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antibody; labelling; purification; Protein G; Protein A; protein engineering; protein design; combinatorial selection; Bioteknologi; Biotechnology;

    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

  4. 29. Giant Dipole Resonances as Probes of Local Environment in Molecules, Clusters and Solidsl

    Författare :Jarek Luberek; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; single center; photoionization; fullerene; coupled channels; LDA; giant dipole resonance; embedded; time-dependent local density;

    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

  5. 30. On the Diluent and Solvent Effects in Liquid-Liquid Extraction Systems based on Bis-triazine-bipyridine (BTBP) ligands

    Författare :Elin Löfström Engdahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Solvent effects; Diluent effects; GANEX; Interfacial tension; Density;

    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.
