  1. 1. (1,3-di-tert-butyltriazenide) Cu(I) as vapor deposition precursor

    Kandidat-uppsats, Linköpings universitet/Kemi

    Författare :Peggy Bagherzadeh; [2023]
    Nyckelord :Vapor deposition; CVD; ALD; triazenide;

    Sammanfattning : In the past few decades, devices such as computers have become smaller, and their performance has improved beyond comparison. Semiconductors and interconnectors are used in almost all devices today and are made of thin films. LÄS MER

  3. 2. Characterization of NiMo catalysts with noble metal promoters

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Filip Hallböök; [2023]
    Nyckelord :Catalysis; Hydrodeoxygenation; TPR; NiMo-catalysts; Chemical engineering; Chemistry;

    Sammanfattning : To be able to face the challenges brought on by climate change there is an urgent need to reduce the heavy dependence on fossil fuels. Bio-oil is one such renewable and carbon-neutral replacement that has shown promising potential. A key step in making bio-oil commercially feasible is improvements of the upgrading processes of the bio-oil. LÄS MER

  4. 3. Scandinavian Rock Art Pigments and Their Preparation - A Pilot Study on the Use of SCiO in Heritage Science

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Ingrid Søgaard; [2018-07-02]
    Nyckelord :NIR; red earth; ochre; PCA; SEM-EDX;

    Sammanfattning : This Master’s thesis focuses on firing, aging and provenance of ochres and ochreous soils. It investigates which preparation methods are most significant as separation factors when near infrared (NIR) spectra of prepared pigments are statistically processed. It is performed from a rock art and heritage science perspective. LÄS MER

  5. 4. Degradation of Microplastic Residuals in Water by Visible Light Photocatalysis

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Tajkia Syeed Tofa; [2018]
    Nyckelord :Microplastics; Low density Polyethylene LDPE ; Heterogeneous photocatalytic degradation; Zinc oxide nanorods; Visible light.;

    Sammanfattning : Microplastic (MP) pollution has recently been recognized as a threat to the biosphere including humans due to its widespread distribution, persistent nature and infinitesimal size. This study focused on the solid phase degradation of microplastic residues (particularly low density polyethylene, LDPE) in water through heterogeneous photocatalysis process by designed photocatalysts of zinc oxide nanorods (ZnO NRs) and platinum nanoparticles deposited on zincoxide nanorods (Pt NPs-ZnO NRs) under visible light irradiation.

  7. 5. Material characterization of multi-layered Zn-alloy coatings on fasteners : Effects on corrosion resistance, electrical conductivity and friction

    Master-uppsats, KTH/Materialvetenskap

    Författare :Ante Vallien; [2018]
    Nyckelord :ZnNi; zinc alloy; multi-layered coating; electrodeposited coating; fasteners; corrosion resistance;

    Sammanfattning : Electroplated zinc-alloy coatings have been used on fasteners in the automotive industry for many years. The coating often consists of three layers: a zinc-alloy layer, a passivation layer and a sealer or top-coat. LÄS MER
