1. 11. Polymer Gels: Modeling the Swelling Behavior

   Författare :Stefanie Schneider; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; Polymerteknik; biopolymers; Polymer technology; binding isotherms; polyelectrolyte-surfactant interactions; discontinuous volume transition; gel swelling; Monte Carlo simulation; polyelectrolyte gels;

   Sammanfattning : This thesis is concerned with the swelling behavior of polyelectrolyte gels. The thesis can be divided into two parts. Part one deals with the modeling and computer simulation of the gel swelling. LÄS MER

3. 12. Associative Polymer-Polymer and Polymer-Surfactant Systems: Phase Behaviour and the Influence of Chemical Reactions

   Författare :Salome Santos; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Aqueous mixtures of two non-ionic polymers, poly(acrylic acid) (PAA) and the amphiphilic triblock copolymer, (EO)27(PO)67(EO)27, known by its trade name Pluronic® P104, showed an associative phase separation (miscibility gap), which decreased with the decrease of PAA length. It was found that PAA is a much less selective “solvent” to P104 molecules than water. LÄS MER

4. 13. Swelling and Microstructure of Nanoplatelet Systems

   Författare :Axel Thuresson; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanoplatelets; Model clay system; Coarse grained models; Statistical mechanics; MC simulations; MD simulations; SAXS; Cryo-TEM; Laponite; Montmorillonite; Swelling; Tactoid;

   Sammanfattning : Many clay minerals consist of charged nanoplatelets that swell in an aqueous solution. The swelling and the microstructure depend on the type of clay mineral but are also dependent on, for example, the ionic composition and the temperature of the solution. LÄS MER

5. 14. Amphiphilic Molecules in Aqueous Solution

   Författare :Gerd Persson; Göran Lindblom; Håkan Edlund; Björn Lindman; Umeå universitet; []
   Nyckelord :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; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

   Sammanfattning : 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.

7. 15. Moleculary imprinted micro- and nanoparticles for cancer associated glycan motifs

   Författare :Liliia Mavliutova; Börje Sellergren; Michael Whitcombe; Malmö universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Moleculary imprinted polymer; sialic acid; glycan recognition; synthetic receptor;

   Sammanfattning : Sialic acids are an important family of monosaccharides that are typically found as terminal moieties of glycans. Aberrant sialylation has been proven to correlate with various diseases including cancer. Glycosylation analysis is complex due to high diversityof the glycan isomers and their low abundance. LÄS MER
