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 institutionenSammanfattning : 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.

2. Fabrication and Evaluation of Sb2Te3/PVDF Hybrid Thermoelectric Films
Master-uppsats, KTH/Tillämpad fysikSammanfattning : 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
3. Block Copolymer Lithographyfor Nano-porous Oxide Thin Films
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)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
4. Preparation, characterization and testing of model catalysts for CO oxidation and CO2 hydrogenation
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/SynkrotronljusfysikSammanfattning : 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
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 geovetenskaperSammanfattning : 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
