  1. 1. Rheological Behaviour of Biopolymer Gels in Relation to Structure

    Author : Mats Stading; Chalmers University of Technology; []
    Keywords : particulate gels; fine-stranded gels; mixed gels; biopolymer gels; inhomogeneous gels; rheological properties; rheological behaviour;

    Abstract : The rheological behaviour of biopolymer gels with different network structures was studied to elucidate how the structure of the gel influences its rheological properties. Non-destructive viscoelastic measurements and fracture techniques were used. READ MORE

  2. 2. Structure design for perception of sweetness in food gels

    Author : Karin Holm; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diffusion; pectin; texture; gelatin; gels; sensory analysis; rheology; sweetness;

    Abstract : The production of foods with reduced sugar contents is desired and asked for. However, when reducing the sugar concentration, sweetness and structure and texture properties are altered. There is thus a need for a deeper understanding of the complex relations between a food’s structure, texture and taste. READ MORE

  3. 3. Swelling and Mechanical Properties of Polymer Gels: Salt, Macroion and Network Topology Effects

    Author : Samuel Edgecombe; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; volume decrease upon uniaxial extension; interpenetrating networks; loose-end effects; polydispersity effects; macroion deswelling; salt deswelling; polymer gels; polyelectrolyte gels; Physical chemistry; Fysikalisk kemi;

    Abstract : The work in this thesis concerns polymer gels, especially their swelling and mechanical properties modelled using a coarse-grained model of polyelectrolytes. The method used to study polymer gels was molecular simulation utilising the simulation package MOLSIM. READ MORE

  4. 4. Polymer Gels: Modeling the Swelling Behavior

    Author : Stefanie Schneider; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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;

    Abstract : 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. READ MORE
