    Sammanfattning : Behandling med käkbensförankrade tandimplantat är en vanlig metod för att ersätta förlorade tänder hos helt och partiellt tandlösa patienter. Trots att implantatbehandling uppvisar en långsiktigt hög lyckande- och överlevnadsfrekvens (90–95% efter 10 år) så förekommer implantatförluster och marginal benförlust kring implantaten under det första året efter insättning och/eller belastning, vilket kan försämra det estetiska resultatet.

    Sammanfattning : In-vitro diagnostics plays a very important role in the present healthcare system. It consists of a large variety of medical devices designed to diagnose a medical condition by measuring a target molecule in a sample, such as blood or urine. LÄS MER

  4. 3. Heterogeneous Film-Forming Latexes : Preparation - Morphology - Mechanical Properties

    Författare :Ola Karlsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; core-shell; particle morphology; heterogeneous latexes; particle size; crosslinking; hydrophilicity; poly isoprene-co-styrene-co-methacrylic acid ; monomer partitioning; internal particle viscosity; transmission electron microscopy TEM ; calorimetric reactor; two-stage; seeded emulsion polymerization; film morphology; mechanical properties; paper coating.; Polymer technology; biopolymers; Polymerteknik;

    Sammanfattning : This thesis describes the preparation of heterogeneous latexes, which may serve as binders in coating applications, and the characterization of these. The latexes were prepared in two-stage seeded emulsion polymerization. LÄS MER

  5. 4. Steric Stabilization of Polylactide particles achieved by Covalent 'grafting-from' with Hydrophilic Polymers

    Författare :Robertus Wahyu Nayan Nugroho; Ann-Christine Albertsson; Karin Odelius; Anders Höglund; Mark Rutland; Martina Janstål; KTH; []
    Nyckelord :Steric stabilization; AFM; hydrophilicity; surface modification; poly lactide ; acrylamide; acrylic acid; maleic anhydride;

    Sammanfattning : Despite numerous advantages of using particles in a wide range of applications, they have one drawback that is their tendency to agglomerate. One way to overcome this problem is to sterically  stabilize the particles by introducing polymeric  chains covalently attached to the surface. LÄS MER
