2. 1. Structure and Phase Behavior of Protein Solutions

   Author : Björn Persson; Beräkningskemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistical Mechanics; Simulations; Protein Interactions; Phase Separation; Aggregation; Mutual Amplification;

   Abstract : The complexity of proteins is reflected in the structure of their fluids. This is seen from strongly inhomogeneous distributions about the single protein. Using molecular simulations of protein models, based on experimental structures, the present work probes the directional forces between proteins. READ MORE

4. 2. Phase Separation and Gelation of Biopolymers in Confined Geometries

   Author : Sophia Wassén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; gelation; gelatin–maltodextrin; whey protein isolate–gellan gum; structure evolution; confinement; biopolymer mixture; image analysis.; spinodal decomposition; phase separation; confocal laser scanning microscopy; microstructure;

   Abstract : Many biopolymer mixtures exhibit segregative phase separation that generates regions enriched in one polymer and depleted in the other. Today, much is known of how phase separating biopolymer systems behaves in bulk phase, and the final morphology can be controlled and tailored with high precision. READ MORE

5. 3. Enhancement and Characterization of Films for Barrier and Release Applications

   Author : Maria Petersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; release; edible materials; petroleum wax; starch; acetoglyceride; microstructure; water vapour permeability; phase separation; protein;

   Abstract : Films and coatings can improve the quality and shelf-life of food products by acting as barriers to e.g. water vapour and oxygen. Many edible biopolymer films, based on polysaccharides and proteins, form excellent oxygen barriers but most often provide only poor water vapour barriers. READ MORE

6. 4. Structure and Phase Stability of Polyelectrolyte-Macroion Solutions

   Author : Marie Skepö; Kemiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; hydrophobicity; spatially distributed interaction sites; protein-polymer interaction; Monte Carlo Simulations; redissolution; phase separation; cluster; complex; Polyelectrolytes; macroions;

   Abstract : Polyelectrolytes are polymers bearing ionisable groups, which, in polar solvents, can dissociate into charged polymer chains (polyelectrolytes) and small counterions. In aqueous solutions, polyelectrolytes interact strongly with other macroions and in particular they tend to associate with objects of opposite charge and form complexes. READ MORE

7. 5. Protein-Polymer Interaction and Association in Aqueous Solution

   Author : Malin Jönsson; Biokemi och Strukturbiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; Makromolekylär kemi; Macromolecular chemistry; enzymologi; Proteiner; enzymology; Proteins; Aqueous two-phase systems; Monte Carlo Simulations; hydrophobic effect; surface hydrophobicity; plasmid DNA; Protein; polymer;

   Abstract : The aim of this thesis has been to study protein-polymer interaction and association. Two different techniques were used; Monte Carlo simulations were combined with partitioning in polymeric aqueous two-phase systems. Monte Carlo simulations have been used to evaluate the hydrophobic interaction in electrolyte solution. READ MORE
