  2. 1. Hyaluronan Based Biomaterials with Imaging Capacity for Tissue Engineering

    Author : Yu Zhang; Dmitri Ossipov; Carsten Werner; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hyaluronan; hydrogel; scaffold; tissue engineering; imaging; interpenetrating network; MRI; fluorescence imaging; scaffold degradation;

    Abstract : This thesis presents the preparation of hyaluronan-based biomaterials with imaging capability and their application as scaffolds in tissue engineering. First, we have synthesized HA derivatives functionalized with different chemoselective groups. READ MORE

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

    Author : Samuel Edgecombe; Fysikalisk kemi; []
    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

  7. 5. Effect of solvents during material treatment applications : tuning hydrophilicity of silicone rubber and drug loading in mesoporous silica

    Author : Anna Hillerström; Jan van Stam; Lennart Piculell; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solvents; liquid carbon dioxide; Interpenetrating Polymer Network IPN ; silicone rubber; hydrophilic; phase domains; mesoporous silica; ibuprofen; adsorption isotherms; release; Kemi; Chemistry;

    Abstract : Choosing the right solvent is critical for many industrial applications. A useful property for selection of solvents is their solubility parameters. This concept of solubility parameters is central to this thesis and has been used in two different case studies of material treatment applications. READ MORE
