  1. 1. Hot-carrier extraction in nanowires

    Författare :Jonatan Fast; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanowire; Hot carrier; photovoltaic; Thermoelectric; Fysicumarkivet A:2023:Fast;

    Sammanfattning : A hot-carrier solar cell aims to generate power from energetic, photoexcited, charge carriers, so called hot carriers, in order to reach higher conversion efficiencies than current solar cell technology.Creating a hot-carrier solar cell has proven challenging for two main reasons: hot carriers lose their energy very quickly, and they need to be extracted over distances of a few hundrednanometers via energy selective filters.

  3. 2. Protein Complexity via Non-Native States: Binding, Stability, and Structural Studies of Calbindin D9k and HAMLET (Human alpha-lactalbumin Made LEthal to Tumor cells)

    Författare :Jonas Fast; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; apoptosis; oleic acid; HAMLET; kinetic trap alpha-lactalbumin; calbindin; calcium; Metabolism; Biokemi; metabolism;

    Sammanfattning : Using optical spectroscopy, nuclear magnetic resonance (NMR), and differential scanning Calorimetry (DSC), I have studied two different calcium binding proteins that can form kinetically trapped altered states. Calcium is very important in numerous biological processes such as blood coagulation, signal transduction, muscle contraction and bone formation. LÄS MER

  4. 3. Elastic properties and structural stabilities of elements and compounds

    Författare :Lars Fast; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : A first principles study of the elastic and structural properties of selected elements and compounds is presented. The theoretical basis for these investigations is the density functional theory, in combination with a full potential linear muffin-tin orbital method. LÄS MER

  5. 4. Artificial Neural Networks for Gas Turbine Monitoring

    Författare :Magnus Fast; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Due to the deregulation of the electricity market the power producers are forced to continuously investigate various means of maintaining/increasing their profits. Improving the electrical efficiency through hardware upgrades is probably the most commonly employed measure, although the interest for enhancements with regard to plant operation is on the rise.
