  1. 11. Evaluating a coarse-grained IDP-model for structure and dynamics

    University essay from Lunds universitet/Biofysikalisk kemi

    Author : Louise Kalander; [2021]
    Keywords : IDP; Intrinsically disordered proteins; Histatin 5; Simulation; Biophysical chemistry; Chemistry;

    Abstract : In this study a coarse-grained model of intrinsically disordered proteins (IDPs) is evaluated to determine whether the model is suitable to use for analyzing the structure and dynamics of IDPs. IDPs are proteins that lack a stable tertiary structure which gives them a flexible structure. READ MORE

  3. 12. Magnetic field design for polarised neutrons in European Spallation Neutron Source instruments

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

    Author : Andrea Monzani; [2021]
    Keywords : FEM; COMSOL; uniform magnetic field; neutron scattering; European Spallation Source; neutron adiabaticity; neutron spin filtering; neutron spin transport; 3He polarisation analyser; Halbach coils; tetracoil; instrument design; neutron diffractometer; nuclear physics; material science; physics simulation; Physics and Astronomy;

    Abstract : The goal of this project is the design of the magnetic field of the neutron analyser for the European Spallation Source instrument DREAM (Diffraction Resolved by Energy and Angle Measurements). This instrument is a neutron diffractometer and its purpose is the determination of the magnetic and chemical structure of materials. READ MORE

  4. 13. Event-based High Resolution X-ray Imaging using Compton Coincidence Detection

    University essay from KTH/Medicinsk avbildning

    Author : Eva Bergström; [2021]
    Keywords : Photon counting CT; Compton scattering; Compton kinematics; coincidence detection; χ2 test; Fotonräknande CT; Compton-spridning; Compton-kinematik; sammanfallsdetektering; χ2 -test;

    Abstract : Research on photon counting detectors (PCDs) is focused on semiconductor materials, and silicon is a strong candidate to use in PCDs for photon counting computer tomography (CT). In a silicon detector, a significant portion of the counts is due to Compton scattering events. READ MORE

  5. 14. Investigation on liquid liquid phase separation of lysozyme by dynamic light scattering

    University essay from Stockholms universitet/Fysikum

    Author : Hanna-Friederike Poggemann; [2021]
    Keywords : Protein; protein dynamics; Liquid-liquid phase separation; DLS;

    Abstract : The liquid-liquid phase separation (LLPS) of biomolecules is a phenomenon which received a lot of attention in the last years because it is not only related to theformation of membraneless organelles but also to neurodegenerative diseases. Lysozyme is a globular protein that undergoes LLPS in a buffer salt system andfor that it is well investigated with several techniques like microscopy, dynamic lightscattering (DLS) or small-angle X-ray scattering.

  6. 15. Iron-catalyzed graphitization of biochar to produce graphitic carbon materials

    University essay from KTH/Materialvetenskap

    Author : Ziyi Shi; [2021]
    Keywords : graphite; biochar; catalyst; catalytic graphitization; grafit; biokol; katalysator; katalytisk grafitisering;

    Abstract : Demand for high-quality graphite is expected to experience an extraordinary growth rate, in large part due to its wide range of industrial applications such as adsorbents, lubricants, electrodes, etc. This thesis developed a novel sustainable approach to produce green-graphite materials by applying biochar, acarbon-rich valuable by-product obtained from biomass, as a carbon precursor.
