  2. 2. Steric Stabilization of Polylactide particles achieved by Covalent 'grafting-from' with Hydrophilic Polymers

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Robertus Wahyu Nayan Nugroho; KTH.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steric stabilization; AFM; hydrophilicity; surface modification; poly lactide ; acrylamide; acrylic acid; maleic anhydride;

    Sammanfattning : Despite numerous advantages of using particles in a wide range of applications, they have one drawback that is their tendency to agglomerate. One way to overcome this problem is to sterically  stabilize the particles by introducing polymeric  chains covalently attached to the surface. LÄS MER

  3. 3. Interfacial properties of calcium montmorillonite in aqueous solutions Density functional theory and classical molecular dynamics studies on the electric double layer

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Guomin Yang; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clay minerals; Bentonite; density functional theory; molecular dynamics; GROMACS; electric double layer; electrolytes; ionic liquids; primitive model; CLAYFF forcefield.; Chemical Engineering; Kemiteknik;

    Sammanfattning : The swelling properties of Bentonite are highly affected by clay content and the clay-water interactions that arise from the ion distribution in the diffuse double layer formed near the charged montmorillonite (or smectite) surfaces. Existing continuum models describing the electric double layers, such as classical Poisson-Boltzmann and DLVO theory, ignore the ion-ion correlations, which are especially important for multivalent ions at high surface charge and ionic strength.

    Detta är en avhandling från Magnus Norgren, Mid Sweden University, SE-851 70 Sundsvall, Sweden

    Författare :Magnus Norgren; Mittuniversitetet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; kraft lignin; sodium taurodeoxycholate; bile acid salts; stabilisa-tion; Hofmeister series; fractals; DLCA; RLCA; self-aggregation; colloid; self-diffusion coefficients; DLVO; Poisson-Boltzmann; pKa; dissociation; macromolecule; kraft cooking; lignin; Fysikalisk kemi; Physical chemistry; cryo-TEM; light scattering; 1H PFG NMR;

    Sammanfattning : This thesis describes the physical chemistry of softwood kraft lignin in aqueous alkaline solutions. Both fundamental and applicational aspects are discussed. Kraft lignin originates either from pulp fibres or from black liquor produced by kraft cooking. LÄS MER

  5. 5. Self-organization of nanoparticles - implications for interface biology

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Anders Lundgren; Göteborgs universitet.; Gothenburg University.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gold nanoparticles; self-organization; self-assembly; nanostructure; nanopatterns; cell surface interactions; chemical gradients;

    Sammanfattning : Cells bind to their surroundings via proteins displayed on the cell surface. These interactions support the cells and are important for many cellular processes, e.g. cell migration during morphogenesis, wound healing and cancer metastasis. LÄS MER
