  2. 17. Tellurium interaction with surfaces in the containment and sea-salt residue

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Fredrik Espegren; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; server nuclear accident; Keywords: tellurium; seawater; deposition; chemistry; containment;

    Sammanfattning : In the event of a nuclear accident, the release of radionuclides is always a concern. The extent of such releases is affected by several factors, for example type of atmosphere, temperature, and what structural materials are present during the accident. LÄS MER

  3. 18. Kinetic Measurements Using Nanoplasmonic Sensing

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Markus Schwind; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sn Nanoparticles; Sensing; Localized Surface Plasmon Resonances; Particle Plasmon; Metal Oxidation; Metal Corrosion; Solid-Liquid Phase Transition; Kinetics; Al Nanoparticles;

    Sammanfattning : In this thesis the nanoplasmonic sensing technique was used to study kinetics of (i) the oxidation of Al nanoparticles in air and water and (ii) the solid-liquid phase transition in Sn nanoparticles. The nanoplasmonic sensing technique detects changes of the localized surface plasmon resonance (LSPR) in metal nanoparticles. LÄS MER

  4. 19. Modification of microcapsules for controlled release

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Markus Andersson Trojer; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; coordination chemistry; colloidal stability; imidazole; controlled release; polyelectrolyte multilayer; block copolymer; electron paramagnetic resonance; cross-linking; vibrational spectroscopy; Microcapsule; quartz crystal microbalance with dissipation;

    Sammanfattning : Fouling of marine organisms such as algae and barnacles on the boat hull is an enormous problem for the shipping industry. The negative consequences for the society are both economical and environmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. LÄS MER

  5. 20. Highly Efficient CIGS Based Devices for Solar Hydrogen Production and Size Dependent Properties of ZnO Quantum Dots

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :T. Jesper Jacobsson; Uppsala universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ZnO; Nanoparticles; Quanum Dots; Size Dependent Properties; Hematite; CIGS; Solar Water Splitting; Hydrogen Production; PEC; Photoelectrochemical cells; PV-electrolysis; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : Materials and device concepts for renewable solar hydrogen production, and size dependent properties of ZnO quantum dots are the two main themes of this thesis.ZnO particles with diameters less than 10 nm, which are small enough for electronic quantum confinement, were synthesized by hydrolysis in alkaline zinc acetate solutions.
