  2. 1. NMR Diffusometry and Dynamic NMR Microscopy Studies of Colloidal Systems

    Author : Helena Wassenius; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion behaviour; dynamic NMR microscopy; NMR diffusometry; core-shell latex particles; NMR velocimetry; rheology; colloidal systems;

    Abstract : In this thesis, the NMR diffusometry and dynamic NMR microscopy methods were shown to be useful techniques with a great potential for the study of colloidal systems. In Paper I-II, NMR diffusometry was used to study the behaviour of surfactant and polymer molecules that are normally important components in colloidal dispersions and emulsions. READ MORE

  4. 2. Characterizing Chromatography Media : NMR-based Approaches

    Author : Fredrik Elwinger; István Furó; Stéphane Viel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chromatography; nuclear magnetic resonance; NMR; self-diffusion; magic-angle spinning; quantitative; distribution coefficient; pore size; Kemi; Chemistry;

    Abstract : Liquid chromatography is an essential technique in manufacturing biopharmaceuticals where it is used on all scales from analytical applications in R&D to full-scale production. In chromatography the target molecule, typically a protein, is separated and purified from other components and contaminants. READ MORE

  5. 3. NMR Studies of Colloidal Systems in and out of Equilibrium

    Author : Pavel V. Yushmanov; Peter Stilbs; Terence Gosgrove; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stopped-flow NMR; temperature-jump NMR; crossrelaxation; NMR; NMR probe; fluorosurfactant; micellar kinetics; micellar structure; Physical chemistry; Fysikalisk kemi;

    Abstract : The Thesis describes (i) the development of add-on instrumentation extending the capabilities of conventional NMR spectrometers and (ii) the application of the designed equipments and techniques for investigating various colloidal systems. The new equipments are: Novel designs of stopped-flow and temperature–jump inserts intended for conventional Bruker wide-bore superconductive magnets. READ MORE

  6. 4. Development and applications of NMR relaxation methods to study protein and ligand dynamics

    Author : Sven Wernersson; Biofysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear magnetic resonance; NMR; NMR relaxation; Method development; Protein dynamics; BRD4; Galectin 3; Kärnmagnetisk resonansspektroskopi; proteindynamik; Metodutveckling; NMR; BRD4; Galektin 3;

    Abstract : This thesis involves the study of proteins. These molecules exist in many variants, and perform most of our bodily functions. This includes signaling (for example the presence of capsaicin, which makes food spicy), molecular transport (including oxygen), catalysis (including food digestion) and part of our body structure (such as muscles).

  7. 5. NMR Investigations of Host-Guest Complexes and Their Dynamic Properties

    Author : Zdenek Tosner; Jozef Kowalewski; Josef Stepanek; Klaus Muller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supramolecular chemistry; host-guest complexes; non-covalent interactions; nuclear magnetic resonance; molecular motion; C-13 relaxation; deuterium NMR; dipolar recoupling; Physical chemistry; Fysikalisk kemi;

    Abstract : This thesis discusses several different methods offered by solution and solid state nuclear magnetic resonance for investigation of host-guest complexes and their constituents. The presented methods were used especially (but not exclusively) to address rotational dynamics of the bound guest in different molecular systems. READ MORE
