  1. 11. Thin films for indoor air monitoring Measurements of Volatile Organic Compounds

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Umut Cindemir; Uppsala universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas sensor; thin film; adcanced gas depostion; sputter deposition; nickel oxide; gold nanoparticles; indium tin oxide; acetaldehyde; formaldehyde;

    Sammanfattning : Volatile organic compounds (VOCs) in the indoor air have adverse effects on the dwellers residing in a building or a vehicle. One of these effects is called sick building syndrome (SBS). LÄS MER

  2. 12. Metal Oxide Thin Films and Nanostructures Made by ALD

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mårten Rooth; Uppsala universitet.; [2008]
    Nyckelord :Inorganic chemistry; Atomic layer deposition; Metal oxide; Nanostructures; Template deposition; Thin films; Oorganisk kemi;

    Sammanfattning : Thin films of cobalt oxide, iron oxide and niobium oxide, and nanostructured thin films of iron oxide, titanium oxide and multilayered iron oxide/titanium oxide have been deposited by Atomic Layer Deposition (ALD). The metal oxides were grown using the precursor combinations CoI2/O2, Fe(Cp)2/O2, NbI5/O2 and TiI4/H2O. LÄS MER

  3. 13. Fabrication and Corrosion Properties of Nickel Silicides Thin Films

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Eric Tam; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nickel silicides; ion-beam sputter deposition; potentiodynamic polarisation measurements; X-ray photoelectron spectroscopy; corrosion.; thin films;

    Sammanfattning : Surface engineering is a vital issue in engineering materials design. The enhancement of surface properties extends the materials lifetime and improves the materials performance without changing the bulk properties. Thin film deposition is one of the most commonly applied techniques in this field. LÄS MER

  4. 14. Electrochromism in Nickel-based Oxides Coloration Mechanisms and Optimization of Sputter-deposited Thin Films

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Esteban Damián Avendaño Soto; Uppsala universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Nickel based Oxide; Electrochromism; Thin Films; Sputtering; Coloration mechanism; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : Electrochromic properties of sputter-deposited nickel-based oxide films have been studied with a two-fold goal. From a practical point of view, the optical switching performance has been improved by optimizing the deposition conditions and film stoichiometry with respect to oxygen and hydrogen, and further by adding Mg, Al, Si, Zr, Nb or Ta to the films.

  5. 15. Colloidal synthesis of metal oxide nanocrystals and thin films

    Detta är en avhandling från Institutionen för fysik, kemi och biologi

    Författare :Fredrik Söderlind; Linköpings universitet.; Linköpings universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; synthesis; contrast agents; functionalization; thin films; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Sammanfattning : A main driving force behind the recent years’ immense interest in nanoscience and nanotechnology is the possibility of achieving new material properties and functionalities within, e.g., material physics, biomedicine, sensor technology, chemical catalysis, energy storing systems, and so on.
