  1. 1. NMR Studies of Colloidal Systems in and out of Equilibrium

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

    Sammanfattning : 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. LÄS MER

  3. 2. Interactions Between Biopolymers and Surfactants with Focus on Fluorosurfactants and Proteins

    Författare :Lubica Macáková; Per Claesson; Fredrik Höök; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Sammanfattning : The aim of this thesis was to obtain a better understanding of the association between surfactants and biopolymers in bulk solutions and at solid/aqueous liquid interface. In order to do this, the interactions between surfactants and biopolymers were investigated with a variety of experimental techniques. LÄS MER

  4. 3. Preparation, characterisation and wetting of fluorinated cellulose surfaces

    Författare :Christian Aulin; Lars Wågberg; Sigbritt Karlsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : This thesis deals with the wetting by oil mixtures of two different model cellulose surfaces. The surfaces studied were a regenerated cellulose (RG) surface prepared by spin-coating, and a film consisting of polyelectrolyte multilayers (PEM) of Poly(ethyleneimine) (PEI) and a carboxymethylated Microfibrillated Cellulose (MFC).

  5. 4. Molecular Association Studied by NMR Spectroscopy

    Författare :Lars Nordstierna; István Furó; Peter Griffiths; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR; spin relaxation; self-diffusion; intermolecular cross-relaxation; chemical shift; fluorinated surfactants; hydrogenated surfactant; micelle; non-ideal mixing; adsorption; hydration; surfactant-protein association; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : This Thesis presents studies of molecular association in aqueous solution and at the liquid/solid interface. The investigated molecular systems range from self-aggregating surfactants to hydration water in contact with micelles or individual molecules. In most studies, combinations of various NMR methods were applied. LÄS MER
