  1. 11. Thermodynamic modelling of the copper-zinc-tin ternary system : A study towards lead-free brass

    University essay from KTH/Materialvetenskap

    Author : Caterina Radogna; [2023]
    Keywords : Brass-based alloys; Lead-free brass; Calphad; Thermo-Calc; Thermodynamic description; Mässingsbaserade legeringar; Blyfri mässing; Calphad; Thermo-Calc; Termodynamisk beskrivning;

    Abstract : Lead (Pb) is frequently used as an alloying element in brass to enhance machinability and castability. However, this element poses a significant risk to human health and the environment. The 2021 revision of the Drinking Water Directive imposed stricter limits on Pb content in brass, encouraging the development of lead-free brass. READ MORE

  3. 12. Path Integrals in Quantum Mechanics and Low-Dimensional QFT

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Johanna Adbo; [2023]
    Keywords : QFT; path integrals; quantum mechanics; kvantfältteori; vägintegraler; kvantmekanik;

    Abstract : The focus of this thesis is to introduce the path integral and some of its applications. One interpretation of quantum mechanics is that a microscopic system which moves from an initial- to a final state moves through each possible intermediate state. READ MORE

  4. 13. Effect of DNAJB6 on α-synuclein amyloid fibril aggregation and dis-aggregation

    University essay from Lunds universitet/Biofysikalisk kemi

    Author : Josef Getachew; [2023]
    Keywords : α-synuclein; alpha-synuclein; chaperones; DNAJB6; the unhappy chaperone; parkinsons disease; biophysical chemistry; biochemistry; Biology and Life Sciences; Chemistry; Technology and Engineering;

    Abstract : Amyloid proteins are a group of proteins with the ability to form large fibrillar aggregates, identifiable by their cross-β core structure. These aggregates are linked to several different neurodegenerative diseases such as Parkinson’s disease and Alzheimer’s disease and due to the growing rate of people diagnosed, there is a need to combat these diseases.

  5. 14. Numerical simulations oflovastatin crystallization in aT-shaped 2D mixer

    University essay from KTH/Optimeringslära och systemteori

    Author : Anton Bergman; [2023]
    Keywords : ;

    Abstract : The rise of battery driven technology and the strive towards circular economy calls for the indefinite recycling of metals used in batteries. To be able to study and optimize the processes used in recycling, mathematical models are required. READ MORE

  6. 15. Fabrication and characterization of GaAsxP1-x single junction solar cell on Si for III-V/Si tandem solar cell

    University essay from KTH/Tillämpad fysik

    Author : Elaheh Aghajafari; [2023]
    Keywords : III-V semiconductor; GaAsxP1-x heteroeputaxy; hydride vapor phase epitaxy; III-V Si solar cell; III-V halvledare; GaAsxP1-x epitaxiallager; hydridångfasepitaxi; III-V Si solcell;

    Abstract : Silicon based solar cells have been used as photovoltaic devices for decades due to reasonable cost and environment- friendly nature of silicon. But the conversion efficiency of silicon solar cell is limited; for instance, the maximum conversion efficiency of a crystalline silicon solar cell available in the market developed by Kaneka Corporation is 26 % [1].
