  1. 1. Bioanalysis using capillary electrophoresis and mass spectrometry : Applied on proteins, protein nanofibrils and polyvinyl alcohol microbubbles

    Författare :Leila Josefsson; Åsa Emmer; Ulrika Nilsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; : amyloid; capillary electrophoresis; contrast agents; detection; human blood plasma; ionic liquids; mass spectrometry; microbubbles; polyvinyl alcohol microbubbles; protein nanofibrils; proteins; Kemi; Chemistry;

    Sammanfattning : The sequencing of the genome of various species, including the human species, have led to increased understanding about how a protein structure is generated, and how specific structures are related to the proteins’ functionality. In paper I and II of this thesis, the folding of proteins in vitro to form hierarchical nanostructures, which in vivo often have a pathological effect, have been studied. LÄS MER

  3. 2. Effects of plasticizing and crosslinking on the mechanical and barrier properties of coatings based on blends of starch and poly(vinyl alcohol)

    Författare :Asif Javed; Lars Järnström; Henrik Ullsten; Peter Rättö; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Citric acid; Glycerol; Polyethylene glycol; Barrier properties; Starch; Mechanical properties; Polyvinyl alcohol; Adhesion; Cross linking; Extrusion coating; Chemical Engineering; Kemiteknik;

    Sammanfattning : In the last decades, intensive research has been carried out in order to replace oil-based polymers with bio-based polymers due to growing environmental concerns. So far, most of the barrier materials used in food packaging are petroleum-based materials. LÄS MER

  4. 3. Printability and Ink-Coating Interactions in Inkjet Printing

    Författare :Erik Svanholm; Göran Ström; Gunnar Engström; Janet Preston; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coating; inkjet; print quality; printability; pigment; silica; polyvinyl alcohol; colorant; ink absorption; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Inkjet is a digital printing process where the ink is ejected directly onto a substrate from a jet device driven by an electronic signal. Most inkjet inks have a low viscosity and a low surface tension, which put high demands on the coating layer’s porosity and absorbency characteristics. LÄS MER

  5. 4. Structural studies of microbubbles and molecular chaperones using transmission electron microscopy

    Författare :Johan Härmark; Philip JB Köck; Hans Hebert; Reinhard Rachel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscopy; Contrast agent; Microbubble; Polyvinyl alcohol; Single particle analysis; Heat shock protein; Molecular chaperone; Technology and Health; Teknik och hälsa;

    Sammanfattning : Ultrasound contrast agents (CAs) are typically used in clinic for perfusion studies (blood flow through a specific region) and border delineating (differentiate borders between tissue structures) during cardiac imaging. The CAs used during ultrasound imaging usually consist of gas filled microbubbles (MBs) (diameter 1-5 μm) that are injected intravenously into the circulatory system. LÄS MER

  7. 5. Modified Starches in aqueous and plastisol coating

    Författare :Agneta Jansson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Starch; Polyvinyl alcohol; Water vapor barrier; Tensile properties; Rheology; Chemical Engineering; Kemiteknik;

    Sammanfattning : The interest for coatings containing renewable materials has enlarged in the last decade. Materials from the nature are investigated like starch, cellulose derivatives, protein (gelatin), chitosane by many. In this study potato starch has been used. LÄS MER
