  1. 6. Quantum ring with tangential dipoles

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Carmen López Jurado; [2021]
    Nyckelord :Bose-Einstein condensate; Quantum Droplets; Gross-Pitaevskii equation; Physics and Astronomy;

    Sammanfattning : This Bachelor thesis studies the formation of quantum droplets in a dilute dipolar Bose Einstein Condensate with the initial shape of a torus. The main question to address is how this formation occurs as the magnetic dipole moment of the particles changes orientation with respect to the xy plane. LÄS MER

  2. 7. Dipole Orientation of Gas Phase Ubiquitin Using Time Dependent Electric Fields

    Kandidat-uppsats, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Harald Agelii; [2020]
    Nyckelord :dipole orientation; protein; spectography; GROMACS; simulation; single particle imaging;

    Sammanfattning : The method of dipole orientation of protein complexes using electric fields plays a key role in the development of single particle imaging, since it enables orientation of the protein in vacuum. In the orientation process the protein is exposed to an external electric field along which the dipole axis of the protein will eventually align. LÄS MER

  3. 8. Alignment and orientation of Nanowires in a thin film under the influence of an electric field

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Sara Thorberg; [2016]
    Nyckelord :Nanowires; nanotechnology; solar cell; thin film; electric field; Physics and Astronomy;

    Sammanfattning : The demand for cheaper and more efficient solar cells is high. One way to decrease cost of material, while maintaining a high degree of efficiency, is to take advantage of nanomaterials. LÄS MER

  4. 9. Interaktions potentialla energin mellan ändliga rektangulära disperserade celullosa nanofibriller

    Kandidat-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :KARAN AHMADZADEH; [2015]
    Nyckelord :NONLINEAR POISSON-BOLTZMANN THEORY; Interaction potential energy; APBS;

    Sammanfattning : Thermodynamically, native cellulose nano fibrils are more stable in an aggregated state. The aggregated state is however not useful from a material development perspective. Therefore much research has been done to stabilize the dispersal of the fibrils. LÄS MER

  5. 10. Motion Tracking Using a Permanent Magnet

    Master-uppsats, Reglerteknik; Tekniska högskolan

    Författare :Jacob Antonsson; [2013]
    Nyckelord :;

    Sammanfattning : In this project the possibility of using a network of magnetometers sensing a permanent magnet for tracking has been investigated. Both the orientation and the position of the magnet have been considered. A dipole approximation of the magnetic field is used to develop two models. LÄS MER
