  1. 1. Phase Change Material : Potential for increased fire resistance in concrete

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :William Toivanen; [2023]
    Nyckelord :Phase change material; concrete; fire resistance; integration into building materials; latent heat; melting;

    Sammanfattning : The European commission has in the Energy Performance of Buildings Directive from 2010 decided that its member states were required to ensure that all new buildings by the end of 2020 were nearly zero-energy buildings. These buildings require small amounts of energy compared to its performance in example by keeping a pleasant indoor climate. LÄS MER

  3. 2. Modeling of carbon plasma discharges in high-power impulse magnetron sputtering

    Master-uppsats, Linköpings universitet/Plasma och ytbeläggningsfysik

    Författare :Henrik Eliasson; [2021]
    Nyckelord :;

    Sammanfattning : Diamond like carbon (DLC) is a metastable state of amorphous carbon that has very important and wide-ranging thin film applications. DLC has a strong resemblance to pure diamond and exhibits many traits of real diamond, like mechanical hardness and chemical inertness, but with a drastically lower deposition cost. LÄS MER

  4. 3. Microstructure and Magnetic Properties for Mn-Al based Permanent Magnet Materials

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Axel Nyberg; [2017]
    Nyckelord :;

    Sammanfattning : Manganese-Aluminium is an alloy with attractive ferromagnetic propertieswhenL10-structured ( -phase). If sucient permanent magnetic propertiescan be achieved at a low cost, it has potential to be a new permanentmagnet material on the market. LÄS MER

  5. 4. Grain Refinement of Commercial EC Grade 1070 Aluminium Alloy for Electrical Application

    Master-uppsats, KTH/Materialvetenskap

    Författare :Massoud Hassanabadi; [2015]
    Nyckelord :pure aluminium; grain refining; fading; columnar grains; equiaxed grains; properzi; electrical conductivity; IACS %;

    Sammanfattning : The aluminium alloys for electrical conductivity applications are generally not grain refinedsince the addition of grain refiners drops the electrical conductivity by introducing impuritiesinto the melt. Non-grain refined aluminium may lead to bar fracture and cracks during themetalworking process. LÄS MER

  7. 5. Electrical Properties of planar Metal-GdN-Metal junctions for Spintronic Applications

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

    Författare :Felicia Ullstad; [2015]
    Nyckelord :nitride; gadolinium; spintronic; rare earth nitride; ferromagnetism; ferromagnetic; Semiconductor; Physics and Astronomy;

    Sammanfattning : In this thesis the properties of planar metal-gadolinium nitride-metal junctions have been studied with the aim of establishing ohmic and Schottky contacts to thin polycrystalline films of n-type gadolinium nitride (GdN). GdN is an intrinsic ferromagnetic semiconductor of the rare earth nitride series. LÄS MER
