  2. 1. 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

  4. 2. Diffusion in cationic vesicle and micellar solutions- a NMR study

    Author : Cecilia Groth; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vesicles; Stopped-flow; micellar kinetics; water transport; DSC; Gemini surfactant; permeability; NOESY; Cationic surfactant; NMR diffusometry; extrusion;

    Abstract : Double tailed cationic surfactants are the active component in softeners. In the beginning of the 90s the active component in softener formulations was changed from a hydrolytically stable dialkyl dimethyl ammonium chloride (dialkyl quat) to a cleavable and biodegradable product containing ester groups in the alkyl chains (dialkyl ester quat).

  5. 3. Interaction between Crosslinked Polyelectrolyte Gels and Oppositely Charged Surfactants

    Author : Peter Nilsson; Per Hansson; Ksenija Kogej; Uppsala universitet; []
    Keywords : Pharmaceutical chemistry; gel; polyelectrolyte; surfactant; deswelling; kinetics; phase separation; volume transition; ion-exchange; diffusion; liquid crystal; SAXS; cubic Pm3n; Farmaceutisk kemi;

    Abstract : The interactions between anionic, crosslinked gels and cationic surfactants have been investigated. When exposed to oppositely charged surfactant, the gel collapses into a dense complex of polyion and micelles. READ MORE

  6. 4. Organic reactions in self-organized surfactant systems

    Author : Fredrik Currie; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic synthesis; kinetics; micelle; regioselectivity; microemulsion;

    Abstract : The aim of this work has been to investigate how microemulsions and micellar systems can be used as reaction media to overcome reactant incompatibility, enhance reaction rates and especially to control product composition, i.e., introducing regioselectivity, in organic synthesis.

  7. 5. Gas-Phase Protein Structure Under the Computational Microscope : Hydration, Titration, and Temperature

    Author : Erik Marklund; David van der Spoel; Albert Heck; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular dynamics; gas phase; proteins; micelles; proton transfer; Grothuss mechanism; kinetics; Physics; Fysik; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Although the native environment of the vast majority of proteins is a complex aqueous solution, like the interior of a cell, many analysis methods for assessing chemical and physical properties of biomolecules require the sample to be aerosolized; that is, transferred to the gas-phase. An important example is electrospray-ionization mass spectrometry, which can provide a wide range of information about e. READ MORE
