  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. Correlating Microstructure with Texture of Particulate Biopolymer Gels

    Author : Maud Langton; Chalmers University of Technology; []
    Keywords : microstructure; image analysis; texture; electron microscopy; lactoglobulin; particulate gels; whey protein; light microscopy;

    Abstract : The microstructure of particulate biopolymer gels has been studied to comprehend the effect of microstructure on textural properties. Particulate structures have been characterized at different levels by using light microscopy, scanning electron microscopy, and transmission electron microscopy. READ MORE

  3. 3. Structure-Control of the Rheological Behaviour of Particulate Gels

    Author : Camilla Olsson; Chalmers University of Technology; []
    Keywords : structure formation; potato amylopectin; structure deformation; rheology; particulate gels; image analysis; beta-lactoglobulin; fracture mechanics; microstructure;

    Abstract : The focus of this thesis is the relation between the rheological and structural properties of mixed particulate gels, based on β-lactoglobulin, determined under both dynamic and static conditions. Rheological characteristics were recorded during formation of the gels, on set gels and during deformation and fracture of the gels, using viscoelastic measurements in shear and in compression and fracture mechanics in tension.

  4. 4. True Monoliths as Separation Media : Homogeneous Gels for Electrophoresis and Electrochromatography in the Capillary and Microchip Modes

    Author : Ákos Végvári; Douglas Westerlund; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; capillary electrophoresis; capillary electrochromatography; gel electrophoresis; agarose; polyacrylamide; b-cyclodextrin; DNA; peptide; glutathione; drug enantiomers; microchip; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : The thesis focuses on the development of new homogeneous gels for the separation of drug enantiomers, peptides, DNA and virus by electrophoresis and electrochromatography in capillaries and microchips. This type of separation media offers high resolution and small zone broadening. READ MORE

  5. 5. Nano-particulate Silica Hydrogels Imaged in 2D and 3D using TEM: Effects of local pore structure on mass transport and applications in aggregation dynamics

    Author : Charlotte Hamngren Blomqvist; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; silica gel; colloidal silica gel; interconnectivity; nanoporous; electron tomography; silica nanoparticle gel; mass transport; nanostructure; accessible volume fraction; 3D structure;

    Abstract : Porous materials are frequently used in everyday applications including food science, pharmaceuticals, fuel cell membranes, batteries and solar cells. A key aspect in these porous materials is how their micro- and nano-structure affect the internal transport of for example water, particles or charges. The transport is a three-dimensional process.
