  1. 1. Properties of modified starches and their use in the surface treatment of paper

    Författare :Anna Jonhed; Lars Järnström; Ann-Charlotte Eliasson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface treatment of paper; hydrophobically modified starches; temperature-responsive starch; inclusion complexes; barrier properties; Surface engineering; Ytbehandlingsteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : The papermaking industry uses a large amount of starch each year, both as a wet-end additive and as a rheological modifier in surface sizing and coating colors. It is important to be able to reduce the amount of chemicals used in the papermaking and surface treatment process, to reduce costs and to make the process even more efficient. LÄS MER

  3. 2. Engineering of Human Fetal Hemoglobin

    Författare :Karin Kettisen; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fetal hemoglobin; protein engineering; recombinant protein production; protein purification; chromatography; oxygen carrier; redox reactions; net surface charge; DNA cleavage;

    Sammanfattning : In blood, the oxygen-transporting protein hemoglobin (Hb) governs the oxygenation of cells and tissues. Naturally, this protein has claimed a place in the center of the research field of artificial oxygen therapeutics. LÄS MER

  4. 3. Surface characterization and manipulation of polyampholytic hydrogel coatings

    Författare :Feng-I Tai; Thomas Ederth; Bo Liedberg; Lei Ye; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrogels; antifouling; charge-balanced material; polyampholytes; force measurements; polymer swelling; protein adsorption; patterning; plasmonics;

    Sammanfattning : This thesis is dedicated to building up fundamental knowledge about polyampholytic hydrogels, which are developed in our group for anti-fouling purposes. Charge-balanced polymers, where positive and negative charges balance each other, have emerged as interesting candidates for many applications in materials science. LÄS MER

  5. 4. Pneumococcal pili and other cell surface properties affect the infection biology of Streptococcus pneumoniae

    Författare :Johannes Ries; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The pneumococcus, Streptococcus pneumoniae, is a major respiratory tract disease causing pathogen with an estimated mortality of 1-2 million per year worldwide. It is the most common bacterial cause of sinusitis, otitis media and community acquired pneumonia and also a major cause of invasive diseases such as septicaemia and meningitis. LÄS MER

  7. 5. Grafted Molecular Layers for Control of Surface Properties

    Författare :Gunnar Dunér; Andra Dédinaité; Stefan Zauscher; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The goal of this thesis work was to develop responsive surface grafted brushlayers for control of surface properties and to gain insights in the molecular mechanisms that control these properties. Three types of grafted layers were investigated, as outlined below. LÄS MER
