  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. Systemdesign för miljövänliga och kostnadseffektiva reservkraftsystem : Undersökning av alternativa reservkraftsystem för en livsmedelsindustri

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Philip Clarstedt; [2024]
    Nyckelord :Backup power; Reservkraft; Hybridsystem; Batterilager; Mikrogasturbin; Dieselgenerator;

    Sammanfattning : Backup power is essential to supply important functions in society with electricity in case of a blackout. Today in Sweden most backup generators are based on diesel fuel and seldom used, but they are still associated with bad environmental impact while operating. LÄS MER

  4. 3. Developing an Automated Drivability Index for Swedish Roadways

    Master-uppsats, KTH/Transportplanering

    Författare :ANDREI DAVID RADU; [2023]
    Nyckelord :;

    Sammanfattning : The masters thesis aims to determine a method to understand which road segments could pose safety risks or where Level 4 autonomous vehicles would operate poorly in the Swedish road context. This vehicle’s ability to operate adequately can be defined as ‘drivable’. LÄS MER

  5. 4. Freight Transport in the Car-Free City : Towards a more sustainable urban freight sector

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Melisa Marta; [2023]
    Nyckelord :Car-free city; sustainable urban freight transport; urban consolidation center; cargo bicycles;

    Sammanfattning : Freight transport of goods is an indispensable part of everyday life. Without it there would be no delivery of products such as food, water, construction material, technology, furniture, clothes and society, as we know it today, would collapse.  However, there are more and less sustainable ways of transporting goods.

  7. 5. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/FREIA

    Författare :Karl-Fredrik Boholm Kylesten; [2023]
    Nyckelord :attosecond; free-electron laser; XFEL; self-amplified spontaneous emission; SASE; tapering; energy modulation;

    Sammanfattning : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. LÄS MER
