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

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/FREIA

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

    Abstract : 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. READ MORE

  4. 3. The Magnetocaloric Effect in Antiferromagnetic and Noncollinear Magnets

    University essay from Uppsala universitet/Materialteori

    Author : Siri Alva Berge; [2023]
    Keywords : magnetocaloric effect; atomistic spin dynamics; monte carlo; antiferromagnet; neodymium; noncollinear magnetism;

    Abstract : The magnetocaloric effect (MCE) is the temperature change in a magnetic material due to a change in an applied magnetic field. How the MCE behaves in different magnetic materials and at different phase transitions is fundamental to understand. READ MORE

  5. 4. Design and processing of metal-organic frameworks for greenhouse gas capture

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Evelina Wiksten; [2023]
    Keywords : Metal-organic frameworks; zeolitic imidazolate frameworks; carbon capture; gas adsorption; direct ink writing;

    Abstract : Anthropogenic emission of greenhouse gases has long been suspected to contribute to global warming and climate change. Most greenhouse gases are emitted in a mixture, so efficient methods and materials to separate and capture the gases are in demand in order to reduce emissions. READ MORE

  6. 5. Potential of tall oil pitch as phase change material in lignin-shelled hybrid nanocapsules for thermal energy storage.

    University essay from Mittuniversitetet/Institutionen för kemiteknik

    Author : Helena Viberg Nissilä; [2022]
    Keywords : phase change materials PCM ; tall oil pitch TOP ; lignin; nanocapsules; hybrid material; thermal storage;

    Abstract : A prospect in utilizing thermal energy in development of energy systems is by the useof phase change materials (PCMs). PCMs are materials that can store and releaseenergy during phase changes, e.g. from solid to liquid. READ MORE
