  1. 1. Friction and Wear Mechanisms of Ceramic Surfaces : With Applications to Micro Motors and Hip Joint Replacements

    Författare :Johanna Olofsson; Staffan Jacobson; Håkan Engqvist; Koshi Adachi; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; Friction; Wear; Ceramic; Tribofilm; Alumina; Silicon nitride; Ultrasonic Motors; Hip Joint Replacement; PVD coating; Materials science; Teknisk materialvetenskap; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : Surfaces exposed to wear always transform and typically a layer of new structure and composition is formed. This layer, often called tribofilm, changes the friction and wear properties. LÄS MER

  3. 2. Ceramic Core–Shell Particles : Synthesis and Use within Dentistry

    Författare :Camilla Berg; Wei Xia; Håkan Engqvist; Nicola Döbelin; Uppsala universitet; []
    Nyckelord :Calcium phosphate; Core-shell particles; Substituting ions; Dentin hypersensitivity; Occlusion; Mineralization; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : Dentin hypersensitivity is one of the most prevalent conditions related to oral health, affecting a large share of the adult population. Shortcomings with the available treatment options are related to non-ideal particle sizes and degradation properties. LÄS MER
