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

    Author : Karin Holm; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; 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

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

    University dissertation from Physical Chemistry 1, Lund University

    Author : Samuel Edgecombe; Lund University.; Lunds universitet.; [2007]
    Keywords : 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

  3. 3. Polymer Gels: Modeling the Swelling Behavior

    University dissertation from Physical Chemistry 1, Lund University

    Author : Stefanie Schneider; Lund University.; Lunds universitet.; [2003]
    Keywords : 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

  4. 4. Catanionic Aggregates in Gels Prolonged Drug Release and Potential Implications for Topical Use

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Noel Dew; Uppsala universitet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PHARMACY Pharmaceutics; FARMACI Galenisk farmaci; Galenisk farmaci; Pharmaceutics;

    Abstract : Gels are popular dosage forms.  This topical dosage form may be advantageous compared to oral or parenteral dosage forms. Favorable rheological or bioadhesive properties of gels might provide extended contact times at the site of administration compared to aqueous solutions. READ MORE

  5. 5. Polymer Gels and their Interactions with Ionic Surfactants

    University dissertation from Physical Chemistry 1, Lund University

    Author : Olof Rosén; Lund University.; Lunds universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Polymer-Surfactant Interactions; Modified Polymers; Binding Isotherm; Polymer Gels; Swelling Isotherm; Fysikalisk kemi;

    Abstract : The response on chemically crosslinked gels and polymer solutions on the addition of ionic surfactants and/or addition of salt at different temperatures have been studied. All polymers studied are water soluble and slightly hydrophobic or hydrophobically modified. READ MORE
