1. Brotthhållfastheten på monolitiska broar av flerskiktad zirkonia med olika konnektordimensioner och placering i en disk - En pilotstudie
Kandidat-uppsats, Malmö universitet/Odontologiska fakulteten (OD)Sammanfattning : Purpose: The purpose of this study was to evaluate the fracture strength of monolithic FDPs of multi-layered zirconia (YML) with different connector dimensions and placement in the disc. Material and method: Forty 3-unit monolithic anterior FDPs were produced, 212223, and divided in four groups (n=10) based on the different connector dimensions and strategies for placement in KATANATM Zirconia Yttria Multi-Layered (YML)-disc.

2. Shear Strength between a Resin Cement and a Cobalt-Chromium Alloy and Yttria-Stabilized Zirconia
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för odontologiSammanfattning : New trademarks appear on the dental market every year and it is difficult to determine whether they should be used in clinical praxis or not. Numerous studies have been carried out to investigate different types of materials, trying to declare which material is best suited for a certain type of restorations. LÄS MER
3. Phase field modelling of LLZO/LCO cathode-electrolyte interfaces in solid state batteries
Master-uppsats, Uppsala universitet/StrukturkemiSammanfattning : This work describes two phase field models for the simulation of the interface evolution between a LiCoO2 cathode (LCO) and a Li7La3Zr2O12 solid electrolyte (LLZO) in a Li-metal/LLZO/LCO battery during high temperature sintering. In these conditions atomic species tend to diffuse into the opposing material, creating an intermediate layer of mixed composition which resists the movement of lithium ions. LÄS MER
4. Shear Strength Between Adhesive Cement and Yttria-Stabilized-Zirconia and Cobalt-Chrome Alloy With and Without Retentive Holes - an in vitro study
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för odontologiSammanfattning : ABSTRACT De-bonding is the most common failure of resin-bonded fixed partial dentures. The aim was to determine if the shear bond strength (SBS) differed between a dental adhesive and a Co-Cr alloy and an yttria-stabilized zirconia (Y-TZP). LÄS MER
5. Skräddad mikrostruktur av gadolinium zirkonat baserade värmebarriärbeläggningar som utsätts för termisk cyklisk utmattning
Magister-uppsats, Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)Sammanfattning : Yttria Stabilized Zirconia (YSZ) is the standard ceramic top coat material used for TBC application. Above 1200°C, issues such as CMAS (Calcium Magnesium Alumino Silicates) infiltration susceptibility, phase instability and high sintering rates limits its long durability. LÄS MER
