  1. 1. On translucent yttria stabilized zirconia ceramics: Mechanical considerations, phase transformation and cement choices

    Författare :Sebastian Franco Tabares; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; zirconia; translucent; yttria; air-borne particle abrasion; 10-MDP; cement;

    Sammanfattning : New zirconia formulations (4Y and 5Y-zirconias) have been introduced for prosthodontic therapy and are commercialized as “translucent” zirconias. No clinical information providing their survival rates or complications has been provided to the date. LÄS MER

  3. 2. Monolithic and semi-monolithic translucent zirconium-dioxide restorations : aspects on design, material and strength

    Författare :Fahad Bakitian; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Although many clinical reports have shown high rates of clinical success associated with fixed dental restorations made of traditional zirconium-dioxide (zirconia), clinical failure due to improper design aiming to achieve high strength and optimal aesthetics, still occurs. Previous clinical and laboratory studies indicated that veneering porcelain and the connector represent the weak parts of the fully-veneered zirconia restorations where failure may occur. LÄS MER

  4. 3. Modelling appearance printing : Acquisition and digital reproduction of translucent and goniochromatic materials

    Författare :Alina Pranovich; Daniel Nyström; Sasan Gooran; Jeppe Revall Frisvad; Sergiy Valyukh; Peter Stefan Nussbaum; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material appearance; 3D printing; Goniochromatism; Translucency;

    Sammanfattning : Colour perception is fundamental to our everyday experiences, allowing us to communicate and interpret visual information effectively. Yet, replicating these experiences accurately poses a significant challenge, particularly in the context of full-colour 3D printing. LÄS MER

  5. 4. Optical Characterisation of Miniature Structures and Translucent Sheets for Daylighting Applications

    Författare :Jacob Jonsson; Arne Roos; Helen Rose-Wilson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Photospectrometry; Light scattering; Optical characterisation; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : For a long time spectrophotometry has been a powerful method of determining optical material properties. Since the technique measures the parameters of interest, reflectance and transmittance, it is in general easy to use and interpret. LÄS MER

  7. 5. Bio-Nano Interactions : Synthesis, Functionalization and Characterization of Biomaterial Interfaces

    Författare :Yixiao Cai; Xia Wei; Mikael Karlsson; Martin Andersson; Uppsala universitet; []
    Nyckelord :Bioactive surfaces; nanocrystalline diamond; hydroxyapatite; protein secondary structure; protein absorption; auditory neurons; single crystalline rutile; nano morphology; surface functionalisation; in vitro biomineralisation; translucent nano-ceramics; bio-window material; material characterisation.; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : Current strategies for designing biomaterials involve creating materials and interfaces that interact with biomolecules, cells and tissues.  This thesis aims to investigate several bioactive surfaces, such as nanocrystalline diamond (NCD), hydroxyapatite (HA) and single crystalline titanium dioxide, in terms of material synthesis, surface functionalization and characterization.
