  1. 1. Solute transport in fractured rocks Analysis of analytical solutions and determination of transport parameters

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Shuo Meng; KTH.; [2020]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fractured rock; Radionuclide transport; Analytical solution; Dispersion mechanisms; Electromigration.; Sprickigt berg; Radionukidtransport; analytisk lösning; Dispersionsmekanismer; Elektromigration.; Chemical Engineering; Kemiteknik;

    Sammanfattning : In order to facilitate the assessment of the safety and function of deep geological repositories for radioactive waste, several models have been developed to describe water flow and transport of solutes in fractured crystalline rock. The rock around the repository is described and modelled as a network of water-bearing fractures. LÄS MER

  2. 2. Copper and Silver Metallization for High Temperature Applications

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Shabnam Mardani; Uppsala universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallization; Copper; Silver; Tantalum; High tempreture; Diffussion; Electromigration; Stability;

    Sammanfattning : High-temperature electrical- and morphological-stability of interconnect is critical for electronic systems based on wide band gap (WBG) semiconductors. In this context, the thermal stability of both Ag and Cu films with Ta and TaN films as diffusion barriers and/or surface-capping layers at high temperatures up to 800 oC is investigated in this thesis.

  3. 3. Transport of Heavy Metals in Soil Subjected to an Electric Field -A Study of the Transport of Copper in Bentonite Clay

    Detta är en avhandling från Stockholm : Kemiteknik

    Författare :Klas Arnerdal; KTH.; [2002]
    Nyckelord :Electrokinetic soil remediation; bentonite; copper; adsorption; electromigration; electroosmosis; pH; potential;

    Sammanfattning : This licentiate thesis addressesphosphorus release from sewage sludge, which is the first stepin phosphorus recovery. The concept ofphosphorus recovery maybe seen as a part of sustainable sludge handling in that it isa means of recycling resources without supplying harmfulsubstances to humans or the environment.

  4. 4. Inconel 718 and Hydrogen

    Detta är en avhandling från Stockholm : Kemiteknik

    Författare :Niklas Ehrlin; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IN718 Hydrogen Embrittlement Cathodic Charging;

    Sammanfattning : The nickel based superalloy IN718 is known to be sensitive to hydrogen, causing degradation of its mechanical properties. The degrading mechanism commonly proposed is based on an increased mobility and density of dislocations, caused by the dissolved hydrogen. This results in a decreased yield stress and a premature fracture. LÄS MER

  5. 5. Drug purity determination by capillary electrophoresis : Practical and theoretical aspects on peak shape and resolution

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Olle Stålberg; Uppsala universitet.; [1997]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

    Sammanfattning : Capillary electrophoresis was used for separation and determination ofdrugs. Structural analogues, enantiomers and rotamers were separated usingderivatized β-cyclodextrins and γ-cyclodextrins as selectors.In order to improve these separation systems different kinds of chargedamphiphiles were introduced in the background electrolyte (BGE).
