  2. 16. Macroscopic modelling of coupled multiphysics in swelling cellulose based materials

    Author : Marcus Alexandersson; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiphysics; multiphase flow; mixture theory; porous media; cellulose based materials; paperboard;

    Abstract : Paperboard has been the basis for packaging materials used to aseptically store and protect food and beverages for a long time. To ensure that there are no bacteria that can spoil the product, sterilizing treatments are made. READ MORE

  4. 17. 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
