  1. 1. Interfacial Adhesion Failure Impact on print-coating surface defects

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hajer Kamal Alm; Lars Wågberg; Göran Ström; Janet Preston; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ink-paper coating adhesion; offset printing; calcium carbonate pigments; polyacrylate; dispersant; print mottle; surface chemistry; hygroscopy of surfaces; coating structure; print quality; water interference mottle; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The aim of this work was to develop a solid knowledge on formulation effects controlling offset ink-paper coating adhesion and to identify key factors of the coating and printing process affecting it. Focus lay on comprehending the impact of pigment dispersant on ink-paper coating adhesion and ultimately on the print quality of offset prints. READ MORE

  2. 2. Cereal Proteins. Interfacial and Physicochemical Properties

    University dissertation from Food Technology, Lund University

    Author : Lars Wannerberger; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; monolayer; Langmuir-Blodgett deposition; interaction; interfacial properties; adsorption; secalin; Wheat proteins; gliadin;

    Abstract : The main theme of this thesis is the interfacial properties of cereal proteins from wheat and rye. Some aspects of dough bulk properties are also included. The proteins studied are of interest for the stabilisation of gas cells and the mechanism of gas retention, and the rheological properties of a bread dough. READ MORE

  3. 3. Drowning-out crystallisation of benzoic acid Influence of processing conditions and solvent composition on crystal size and shape

    University dissertation from Stockholm : Kemiteknik

    Author : Xiomara Holmbäck; [2002]
    Keywords : solvent effect; drowning-out; crystallization; benzoic acid; solubility; crystal habit; crystal growth; interfacial energy; growth mechanism;

    Abstract : The aim of the present investigation is to increase theunderstanding of the role played by the solvent in inhibitingor enhancing crystal growth. Drowning-out crystallizationexperiments has been performed by the controlled addition ofwater or ethanol water mixtures to a saturated solution ofbenzoic acid in ethanol-water mixtures. READ MORE

    Abstract : In this thesis, bio-nanocomposites made from two alternative biopolymers and montmorillonite (Mnt) clay have been investigated by molecular modelling. These biopolymers are xyloglucan (XG) and chitosan (CHS), both of which are abundant, renewable, and cost-effective. READ MORE

  5. 5. Dynamic interactions of interfacial polymers

    University dissertation from Stockholm : Kemi

    Author : Mark Plunkett; [2002]
    Keywords : surface chemistry dynamic polymer interactions QCM AFM MASIF surface forces adhesion friction;

    Abstract : The relationship between the amount and conformation of apolymer at the solid-liquid interface, and the resultinginteraction forces between two such surfaces has beeninvestigated. With a degree of control of the polymerconformation, by varying the temperature, solvent quality,polymer charge density etc, it has been possible to measure andinterpret the resulting changes in the surface interactions.
