  2. 1. Oppositely Charged Polyelectrolytes in Solution

    Author : Yoshikatsu Hayashi; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Monte Carlo simulation; analytical theory; Fysikalisk kemi;

    Abstract : This thesis is about the formation of complexes in solutions of oppositely charged polyions. We consider mainly three topics: 1)Monte Carlo simulations of oppositely charged polyelectrolytes with a focus on cluster compositions. READ MORE

  4. 2. Interaction Between Microgels and Oppositely Charged Peptides

    Author : Helena Bysell; Martin Malmsten; Per Hansson; Walter Richtering; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antimicrobial peptides; binding; cationic peptides; confocal microscopy; deswelling; distribution; electrostatic; homopolypeptides; microgels; peptides; release; swelling; PHARMACY; FARMACI; Pharmaceutical Physical Chemistry; farmaceutisk fysikalisk kemi;

    Abstract : Lightly cross-linked polyelectrolyte microgels are materials with interesting properties for a range of applications. For instance, the volume of these particles can be drastically changed in response to pH, ionic strength, temperature, or the concentration of specific ions and metabolites. READ MORE

  5. 3. Interaction Between Microgels and Oppositely Charged Proteins

    Author : Christian Johansson; Per Hansson; Brian Saunders; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microgel; protein; uptake; distribution; core-shell; colloidal stability; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Abstract : This thesis reports on interactions between microgels and oppositely charged proteins. Two types of negatively charged microgels are investigated: poly(acrylic acid) microgels of 60-80 µm in diameter, and colloidal poly(NIPAM-co-acrylic acid) microgels of around 1 µm in diameter.

  6. 4. 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

  7. 5. Mutual Neutralization in collisionswith oppositely charged fullerene(C60) ions

    Author : Raka Paul; Henning Zettergren; Foivos Perakis; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; fysik;

    Abstract : In this thesis, results from Mutual Neutralization experiment carried out atthe DESIREE facility, involving merged interacting ion beams, of oppositelycharged C60 ions are presented. This reaction may be of importance for explain-ing reliable estimates of the ionization balance in astrophysical environments,which defines the chemistry in molecular gas clouds. READ MORE
