1. On translucent yttria stabilized zirconia ceramics: Mechanical considerations, phase transformation and cement choices
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
2. Monolithic and semi-monolithic translucent zirconium-dioxide restorations : aspects on design, material and strength
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
3. Optical Characterisation of Miniature Structures and Translucent Sheets for Daylighting Applications
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
4. Bio-Nano Interactions : Synthesis, Functionalization and Characterization of Biomaterial Interfaces
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.

5. Social Awareness Support for Cooperation : Design Experience and Theoretical Models
Sammanfattning : This thesis addresses the research question of how social awareness support in computer systems for groups and communities can be designed in a successful way. While the field of human-computer interaction has been working with similar questions for more than 20 years, many aspects of people’s cooperation and the way those should be considered in system design still need further consideration and research.
