  1. 1. Ultrafast dynamics of small quantum systems studied using electron-ion coincidence spectroscopy

    Författare :Smita Ganguly; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coincidence spectroscopy; photodissociation dynamics; fragmentation reaction; MOLECULAR-BEAM; Cluster fission; Astrochemistry; Carbon dioxide CO2 ; ; Adamantane;

    Sammanfattning : Studying how small quantum systems, like molecules and clusters, interact with X-rays is crucial to understanding the ultrafast processes that occur in nature on incredibly short timescales, ranging from femtoseconds to picoseconds. X-rays excite small quantum systems to unstable core hole states, leading to a cascade of phenomena, including Auger decay, nuclear rearrangement, and dissociation. LÄS MER

  3. 2. On the Size and Shape of Polymers and Polymer Complexes : A Computational and Light Scattering Study

    Författare :Tomas Edvinsson; Terence Cosgrove; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Monte Carlo simulations; grafted polymers; shape description; folding complexity; clustering; percolation algorithm; light scattering; end-capped polymers; inclusion complexes; Fysik; Physics; Fysik; Physical Chemistry; Fysikalisk kemi;

    Sammanfattning : Detailed characterization of size and shape of polymers, and development of methods to elucidate the mechanisms behind shape transitions are central issues in this thesis. In particular we characterize grafted polymer chains under confinement in terms of the chain entanglement complexity and mean molecular size. LÄS MER

  4. 3. Probing Proton Translocation in Influenza A/M2 Proteoliposomes - A systematic Approach to Membrane-Protein Reconstitutions

    Författare :Thom Leiding; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : An improved method for reconstituting membrane proteins into artificial liposomes for quantitative functional analysis is presented. A number of key parameters for reconstitution by detergent removal are assessed in this thesis: The lipid-to-protein ratio, the detergent-to-lipid ratio and the lipid and cholesterol composition.

  5. 4. Investigation of Ultrafast Molecular Dynamics via Covariance Mapping : A Tool for Intense XUV Light Sources

    Författare :Jan Lahl; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Covariance; Ultrafast; High-order harmonic generation; Extreme Ultraviolet; Pump probe; FLASH; Velocity map imaging; wavefront; FEL; photodissociation; Coulomb explosion; Fysicumarkivet A:2019:Lahl;

    Sammanfattning : The study of molecular dynamics involves observations of the motion of nuclei and electrons. While nuclear motion is usually on the picosecond or femtosecond timescale, attosecond precision is necessary to directly observe the motion of electrons. LÄS MER

  7. 5. An insight into the metabolism of New Psychoactive Substances : Structural elucidation of urinary metabolites of synthetic cannabinoids and fentanyl analogues using synthesized reference standards

    Författare :Jakob Wallgren; Johan Dahlén; Peter Konradsson; Xiongyu Wu; Mogens Johannsen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : New Psychoactive Substances (NPS) is an umbrella term covering hundreds of substances across different drug groups. Many of these substances were originally developed for therapeutic use but have later appeared on the recreational drug market. LÄS MER
