1. Mechanical and Microstructural Properties of Monolithic Zirconia
Abstract : Zirconia has been widely used in dentistry to improve the strength of ceramic restorations maintaining aesthetics. In addition, zirconia is increasingly being used for monolithic crowns without veneering porcelain. READ MORE

2. On translucent yttria stabilized zirconia ceramics: Mechanical considerations, phase transformation and cement choices
Abstract : 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. READ MORE

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

4. Continuous Fibre Reinforced Oxide/Oxide Composites
Abstract : The appealing properties of ceramics include retention of strength and hardness at high temperatures, chemical inertness and low density. However, monolithic ceramics fail in a brittle, unpredictable manner making them unsuitable for many applications where reliability is a key requirement. READ MORE

5. RhPt and Ni based catalysts for fuel reforming in energy conversion
Abstract : Although current trends in global warming are of great concern, energy demand is still increasing, resulting in increasing pollutant emissions. To address this issue, we need reliable renewable energy sources, lowered pollutant emissions, and efficient and profitable processes for energy conversion. READ MORE
