  2. 11. Associative Multicomponent Polymers in Bulk and at Interfaces

    Author : Fredrik Joabsson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymer adsorption; polymer self-diffusion; polymer-surfactant interactions; phase behaviour; ethyl hydroxyethyl cellulose; hydrophobically modified polymers; capillary-induced phase separation; Physical chemistry; Fysikalisk kemi;

    Abstract : The solution and interfacial properties of an associative water-soluble cellulose derivative, ethyl(hydroxyethyl)cellulose (EHEC) have been investigated. Main themes have been to study the effect of hydrophobic modification of the polymer (HM-EHEC) and the interactions with surfactants, both in bulk and at interfaces. READ MORE

  4. 12. Asymmetric Cellular Microenvironments

    Author : Susanna Rydholm; Hjalmar Brismar; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : This thesis presents methods to combine 3D cell culture, microfluidics and gradients on a controlled cellular scale. 3D cultures in biological extracellular matrix gels or synthetic gels bridge the gap between organ-tissue cultures and traditional 2D cultures. READ MORE

  5. 13. Potato Starch Dispersions: Structure and Rheology

    Author : Karin Svegmark; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The influence of heating, shearing and addition of amylose on the structure and rheology of potato starch dispersions has been evaluated. The methods used were dynamic viscoelastic measurements, light microscopy and transmission electron microscopy (TEM). READ MORE

  6. 14. Phase separation, aggregation and gelation of a charged helixforming polysaccharide in aqueous salt solution

    Author : Johan Borgström; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; polysaccharide; physical gel; ion binding; carrageenan; liquid crystal; polymer; Fysikalisk kemi;

    Abstract : The phase behaviour and gelation of the anionic polysaccharide kappa-carrageenan (KC) in different salt solutions was studied. The specific site binding of certain anions and certain cations to the KC helix was used as a means of controlling the interactions. READ MORE

  7. 15. Faba bean foods: Structure and texture : Evaluation of faba bean component behaviours in different product matrices

    Author : Klara Nilsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Faba bean (Vicia faba minor) is a cool-climate crop that could serve as a locally sourced sustainable ingredient in transition towards a more plant-based diet in temperate regions. Poor texture is one of the main aversion factors of plant-based foods, so this thesis characterised the functionality of faba bean components and their effect on structure and texture in different food matrices.
