  1. 1. Structural analysis of HZO thin film and electrode using X-ray diffraction

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

    Författare :Elliot Winsnes; [2024]
    Nyckelord :HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

    Sammanfattning : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. LÄS MER

  3. 2. Fönsterareans klimatpåverkan : Jämförelse av koldioxidutsläpp från material- och energianvändning när fönsterarea varieras

    M1-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Författare :Philip Möller; Erik Elfstrand; [2023]
    Nyckelord :;

    Sammanfattning : Right now, the world is facing a challenge of reducing carbon emissions. Existing buildings account for one-third of the world's carbon emissions. The construction and real estate sector in Sweden is facing the challenge of combining a high rate of construction with demands on reduced climate emissions. LÄS MER

  4. 3. High-Temperature Thermal Energy Storage for Innovative Hybrid CSP/PV Plants : A Comprehensive Design Optimization

    Master-uppsats, KTH/Energiteknik

    Författare :Lorenzo Centonze; [2023]
    Nyckelord :;

    Sammanfattning : By means of a literature review, critical parameters in the context of thermal energy storage systems, particularly packed bed thermal energy storage systems are identified. The goals of this thesis project are to come up with an optimized design for a PBSTES and to evaluate the thermal performance of alternative storage materials derived from byproducts of industrial processes and natural rocks in order to reduce the environmental impact of the designed system.

  5. 4. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Muhammad Umar Farooq; [2023]
    Nyckelord :Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

    Sammanfattning : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. LÄS MER

  7. 5. Hybrid bridge deck of timber and corrugated steel plates

    Master-uppsats, KTH/Byggnadsmaterial

    Författare :Muze Lu; [2023]
    Nyckelord :;

    Sammanfattning : Over the years, hybrid structures composed of timber and steel have become a potential alternative to conventional solutions. Recently, corrugated steel plate (CSP) has become more and more popular in structures such as shear walls and roofs due to its favorable mechanical properties. LÄS MER
