  1. 1. Template-assisted Electrodeposition and Model Electrodes Studied by Electron Microscopy and High Energy X-ray Diffraction

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Hanna Sjö; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : There is a great interest in studying detailed changes at electrode surfaces during electrochemical processes to better understand the electrochemical reactions at the electrode surface-liquid interface and improve the electrode efficiency. The Au(110) surface has a known (1$\times$2) missing row reconstruction in vacuum conditions, which can change into higher-order (1$\times$3), (1$\times$5), and (1$\times$7) depending on environment.

  3. 2. Fabrication and Evaluation of Sb2Te3/PVDF Hybrid Thermoelectric Films

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Bo Yu; [2020]
    Nyckelord :;

    Sammanfattning : Thermoelectric (TE) materials and devices have been extensively studied for harvesting waste heat energy. There is more interest to fabricate TE materials and devices at low cost and highly-efficient ways. LÄS MER

  4. 3. Block Copolymer Lithographyfor Nano-porous Oxide Thin Films

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yandi Liu; [2018]
    Nyckelord :Block Copolymer; Lithography; Nanopatterning; Reactive-Ion Etching; Oxide Thin Films; Blockcopolymer; Litografi; Nanopakning; Reaktion-Jon Etsning; Oxidtunnfilmerna;

    Sammanfattning : This thesis focuses on employing a new patterning technique called block copolymer lithography to transfer the nano-porous pattern from the polymer template to the underlying oxide thin film. Nano-porous block copolymer films are produced by spin-coating polymer solution on wafers followed by annealing, UV exposure and development processes. LÄS MER

  5. 4. Preparation, characterization and testing of model catalysts for CO oxidation and CO2 hydrogenation

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Stefano Albertin; [2017]
    Nyckelord :Surface science; Rhodium; Nanoparticles; Catalysis; CO2; Physics and Astronomy;

    Sammanfattning : A joint research between Lund University and Chalmers Competence Centre for Catalysis have shown promising results for a Rh-based catalyst for CO2 hydrogenation catalytic applications. The original catalyst consisted of a dispersion of nanoparticles onto a porous 3D oxide network. LÄS MER

  7. 5. Fate and Transport of Nano-TiO2 in Saturated Porous Media: Effect of pH, Ionic Strength and Flow Rate

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Tsegay Mengestab; [2015]
    Nyckelord :Nanoparticles; TiO2; saturated porous media; transport; DLVO theory;

    Sammanfattning : Titanium dioxide nanoparticles are widely used in a variety of products, such as pigments, paints, paper, plastics, cosmetics, nano-fibers, food coloring and photovoltaic cells, and the industry is growing at anexponential rate. It is believed that by 2025, 2.5 million tons of nano-TiO2 will be manufactured annually. LÄS MER
