  1. 1. Protein-water interactions studied by molecular dynamics simulations

    Detta är en avhandling från Department of Chemistry, Lund University

    Författare :Filip Persson; Lund University.; Lunds universitet.; [2018-02-14]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MD simulations; NMR nuclear magnetic resonance ; MRD; water dynamics; protein dynamics; protein hydration; Amide hydrogen exchange; Internal water; compressibility;

    Sammanfattning : Most proteins have evolved to function optimally in aqueous environments, and the interactions between protein and water therefore play a fundamental role in the stability, dynamics, and function of proteins. Although we understand many details of water, we understand much less about the protein-water interface. LÄS MER

  2. 2. Dynamics of Magnetic Molecules under Electrical Control

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Henning Hammar; Uppsala universitet.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular magnets; Spin dynamics; Non-adiabatic effects; Exchange interaction; Thermoelectricity; Fysik; Physics;

    Sammanfattning : This thesis theoretically studies the dynamics of molecular magnets under electrical control. Molecular magnets are nanoscale magnets that can, e.g., consist of single-molecules or single-atoms. LÄS MER

  3. 3. Magnetization dynamics on the nanoscale From first principles to atomistic spin dynamics

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jonathan Philippe Chico Carpio; Uppsala universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : In this thesis first-principles methods, based on density functional theory, have been used to characterize a wide range of magnetic materials. Special emphasis has been put on pairwise magnetic interactions, such as Heisenberg exchange and Dzyaloshinskii-Moriya interactions, and also on in the Gilbert damping parameter. LÄS MER

  4. 4. Cardiovascular fluid dynamics : methods for flow and pressure field analysis from magnetic resonance imaging

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Tino Ebbers; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2001]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN;

    Sammanfattning : Cardiovascular blood flow is highly complex and incompletely understood. Blood flow patterns are expected to influence the opening and closing of normal and prosthetic heart valves, the efficiency of cardiac filling and ejection, and the resistance to thrombus formation within the heart.

  5. 5. Molecular recognition and dynamics in proteins studied by NMR

    Detta är en avhandling från Department of Biophysical Chemistry, Lund University

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemical exchange; Conformational entropy; Entropy; Galectin-3; Isothermal Titration Calorimetry; ITC; Model-free formalism; Molecular recognition; Nuclear Magnetic Resonance; NMR; PGB1; Protein dynamics; Protein–ligand interactions; Proton-transfer reactions; Spin relaxation; Viscosity; Chemical exchange; Conformational entropy; Entropy; Galectin-3; Isothermal Titration Calorimetry; ITC; Model-free formalism; Molecular recognition; Nuclear Magnetic Resonance; NMR; PGB1; Protein dynamics; Protein–ligand interactions; Proton-transfer reactions; Spin relaxation; Viscosity;

    Sammanfattning : Knowledge of dynamics in protein is very important in the description of protein function and molecular recognition. The thesis investigates protein dynamics on time-scales from milli- to sub-nanosecond, with focus on the latter, using NMR spin relaxation experiments on two proteins, the 138-residue carbohydrate recognition domain of galectin-3 (Gal3C) and the 56-residue B1 domain of bacterial protein G (PGB1).
