  1. 1. Structures of Polyelectrolyte Multilayers and Preasorbed Mucin The Influence of Counterions

    University dissertation from Stockholm : KTH

    Author : Zsombor Feldötö; KTH.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry Physical chemistry Surface and colloid chemistry; NATURVETENSKAP Kemi Fysikalisk kemi Yt- och kolloidkemi;

    Abstract : The focus in this thesis has been to gain a fundamental understanding of how different type of salts affect preadsorbed polyelectrolytes, both natural and synthetic. The knowledge from the fundamental work is then applied on a commercial system to investigate if the efficiency can be enhanced. READ MORE

  2. 2. Amphiphilic Molecules in Aqueous Solution

    University dissertation from Stockholm : KTH

    Author : Gerd Persson; Umeå universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; liquid crystal; phase diagrams; counterions; alkylpyridinium octanesulfonates; 1-monooleoyl-rac-glycerol; n-octyl-β-D-glucoside; cubic phases; Fysikalisk kemi; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Abstract : The aim of this thesis was to investigate amphiphilic molecules in aqueous solution. The work was divided into two parts. In the first part the effects of different counterions on phase behavior was investigated, while the second part concerns the 1-monooleoyl-rac-glycerol (MO)/n-octyl-β-D-glucoside (OG)/2H2O-system.

  5. 5. The Influence of Polyelectrolytes on the Stability of Colloids

    University dissertation from Biophysical Chemistry (LTH), Lund University

    Author : Lena Sjöström; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electrostatic interaction; charge reversal; colloid; asymmetric systems; electric double layer; polyelectrolyte; Monte Carlo; Physical chemistry; Fysikalisk kemi;

    Abstract : The interaction between two colloids with grafted polyelectrolytes in aqueous solution is studied within the primitive model by Monte Carlo simulations. For neutral colloids with grafted polyelectrolytes and in absence of salt the interaction is strongly repulsive in absence of salt. READ MORE
