  1. 21. Application of ring statistics to characterise graphitisation of carbon fiber heat shields under atmospheric re-entry conditions

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Hamish Keay; [2023]
    Keywords : Aerospace; Heat shields; Re-entry; Graphitisation; Carbon fiber; Carbon phenolic; Ring statistics; Graph theory; Molecular Dynamics; återinträde; grafitisering; kolfiber; kolfenol; ringstatistik; grafteori; molekylär dynamik;

    Abstract : Carbon fibers submitted to high temperatures (>2000 °C) experience a permanent increasein their thermal conductivity. This change has been attributed to a change in the molecularstructure due to graphitisation. READ MORE

  3. 22. Monte Carlo study of disorder in electronic tight-binding models

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Author : Carl Pettersson; [2023]
    Keywords : Monte Carlo; Tight-binding model; Falicov-Kimball model; Physics and Astronomy;

    Abstract : Oftentimes solids are described by uniform, periodic lattices. In reality, however, there is often some disorder on some of the sites in the lattice. This disorder may come from, for example, there being a different type of atom or tightly bound electrons resulting in a larger on-site potential, affecting the electronic properties of the lattice.

  4. 23. The Stern-Gerlach Spectrometer for Charged Particles : A step towards an alternative method for measuring spin

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Samuel Eriksson; [2023]
    Keywords : Stern-Gerlach; Stern; Gerlach; spin; time-of-flight; time of flight; magnetic moment; spectrometer; Physics and Astronomy;

    Abstract : The purpose of this project is to investigate the performance of a spectrometer capable of measuring both momentum and spin of particles. More specifically, we investigated what parameters are required in order to separate particles with opposite spins at least 1 mm. READ MORE

  5. 24. Quantum mechanical modelling and electrochemical stability of sodium based glassy electrolyte for all-solid-state batteries

    University essay from KTH/Materialvetenskap

    Abstract : Increasing energy demand draws attention to new materials for improving current energy storage technologies. Particular interest is directed at solid state batteries and glass Na3ClO electrolyte is a promising candidate. READ MORE

  6. 25. Benchmarking a memetic algorithm for global all-atom protein-protein docking with backbone flexibility

    University essay from Lunds universitet/Kemiska institutionen

    Author : Vera Karlin; [2022]
    Keywords : biochemistry; EvoDOCK; algorithm; protein; iRMSD; DockQ; CAPRI; Chemistry;

    Abstract : Determining how proteins interact with each other to form complexes is very important for understanding both disease and cellular functions, but experimentally determining the structures of these complexes is both tedious and slow, which is why a great number of protein-protein docking algorithms have been developed to predict them. To this day, conformational changes in protein backbones have been one of the largest challenges when making docking predictions. READ MORE
