  1. 11. Photocatalytic activity of titanium dioxide thin films deposited with high power impulse magnetron sputtering

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Victor Eriksson; [2021]
    Keywords : Photocatalysis; Titanium dioxide; Thin film; HiPIMS; Sputtering; Stearic acid;

    Abstract : High power impulse magnetron sputtering has shown a lot of promise as a way of depositing photocatalytic thin films of titanium dioxide at low temperatures, however, the films deposited are often amorphous and display uncertain photocatalytic abilities. This thesis explores the deposition and characterization of photocatalytic thin films deposited with high power impulse magnetron sputtering. READ MORE

  2. 12. X-ray Photoelectron Spectroscopy on Clusters: From Water Clusters to Metal & Metal-Oxide Nanoparticles

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Emmanouil Tzomos; [2021]
    Keywords : Nanoscience; Nanoparticles; Clusters; Synchrotron Radiation; Water Particles; Silver Particles; Silver Oxides; Ethylene Epoxidation; Radiotherapy; PES; XPS; Lund University; FlexPES; MAX IV; Physics and Astronomy;

    Abstract : In the present work, two experimental setups aimed at the production of (1) water clusters and (2) metal-oxide nanoparticles were assembled and commissioned. The experiments on the cluster/nanoparticle beams were set up and performed at the FlexPES beamline of the MAX-IV synchrotron facility. READ MORE

  3. 13. Biofilm growth on super-acidic metal-oxide films

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Linnéa Jansson; [2021]
    Keywords : Biofilm; nanoteknik; ureas;

    Abstract : In nature, urea is hydrolyzed to ammonia and bicarbonate primarily by enzymes called ureases. As urine waste contains multiple important plant nutrients, there is interest in the waste treatment field to use urine waste products as plant fertilizers. READ MORE

  4. 14. Homebuilt reactor design and atomic layer deposition of metal oxide thin films

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Pamburayi Mpofu; [2021]
    Keywords : Thin films; atomic layer deposition;

    Abstract : This research thesis covers work done on building an atomic layer deposition (ALD) reactor followed by the development and optimization of an ALD process for indium oxide thin films on crystalline silicon substrates from new precursors using this new homebuilt cost-effective tool. This work describes the design, building and testing of the ALD system using an indium triazenide precursor and water in a novel precursor combination. READ MORE

  5. 15. Fertiliser derived from human urine : novel media for alkaline urine dehydration

    University essay from SLU/Dept. of Energy and Technology

    Author : Christopher Friedrich; [2021]
    Keywords : nutrient recovery; fertiliser; urine drying; source separation; magnesium oxide; calcium hydroxide;

    Abstract : Every year, each human excretes approximately 4 kg of nitrogen, 1 kg of potassium and 0.3 kg of phosphorus through their urine. In conventional wastewater treatment, these nutrients are usually not recovered for agricultural production, although they can enhance plant growth. READ MORE
