  1. 16. Aqueous Block Copolymer Systems. Self-association, Phase Behaviour and Partitioning of Biomolecules

    University dissertation from Physical Chemistry 1, Lund University

    Author : Mårten Svensson; Lunds universitet.; Lund University.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; block copolymer self-association partitioning phase behaviour; Physical chemistry; Fysikalisk kemi;

    Abstract : The phase and partitioning behaviour of aqueous block copolymer systems has been studied. The block copolymers used in this work were built up of three blocks. The middle block was poly(propylene oxide) (PPO) and hydrophobic. The two outer blocks constisted of poly(ethylene oxide) (PEO) chains and less hydrophobic. READ MORE

  2. 17. Equilibrium and Nonequilibrium Properties of Nonionic Surfactant Membranes

    University dissertation from Physical Chemistry 1, Lund University

    Author : Thao Le; Lunds universitet.; Lund University.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lamellar; multilamellar vesicle; small-angle x-ray scattering SAXS ; small-angle neutron scattering SANS ; static light scattering SLS ; joule heating temperature jump JHTJ ; dynamic light scattering DLS ; Nonionic surfactants; sponge; elastic curvature energy; Physical chemistry; Fysikalisk kemi;

    Abstract : An extensive investigation of the multilamellar vesicles (La*), lamellar (La), and multiply connected sponge (L3) phase formed in surfactant systems is presented in this thesis. These membrane structures were studied using surfactant systems containing poly(oxyethylene) alkyl ethers, n-CnH2n+1(OCH2CH2) mOH, commonly abbreviated as CnEm. READ MORE

  3. 18. NMR Self-Diffusion Studies of Surfactant and Polymer Systems. Methodology and Applications

    University dissertation from Physical Chemistry 1, Lund University

    Author : Björn Håkansson; Lunds universitet.; Lund University.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi;

    Abstract : The main focus of this thesis has been to explore how the PFG NMR technique for diffusion measurements can be used to obtain useful information from various systems. The investigated systems have one thing in common; they belong to the general field of surface and colloid chemistry. READ MORE

  4. 19. Alkylglycoside Surfactants - Self-Assembly, Solid-State Properties and Interactions with Hydrophobic Molecules

    University dissertation from Department of Physical Chemistry, Lund University

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; peptide stabilisation; solubilisation; micelle morphology; solid-state behaviour; alkylglycosides; nonionic surfactants;

    Abstract : Popular Abstract in Swedish Tensider är en mycket vanlig typ av kemikalier som använts i tusen år och som man ofta stöter på i vardagliga livet. De ingår i exempelvis rengöringsmedel, diskmedel, tvättmedel, lim, målarfärger, hudkrämer och schampo. READ MORE

  5. 20. Polymer effects on microemulsions and lamellar phases

    University dissertation from Physical Chemistry 1, Lund University

    Author : Håkan Bagger-Jörgensen; Lunds universitet.; Lund University.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Poisson-Boltzmann equation; hard sphere; osmometry; small angle scattering; phase behaviour; hydrophobically modified polyelectrolyte; hydrophobically modified polymer; nonionic surfactant; microemulsion; lamellar phase; undulation force; Physical chemistry; Fysikalisk kemi;

    Abstract : The main part of this thesis deals with the effects of adsorbing and non-adsorbing polymers when mixed with microemulsion droplets and bilayers in a lamellar phase. The phase behaviour, microstructure and interactions in a nonionic surfactant/ water/ oil-system, comprising penta ethylene oxide dodecyl ether (C12E5) and decane, was investigated. READ MORE
