Damage tolerance of six dental zirconias with different translucencies

Biomaterial Investigations in Dentistry, 2020
Purpose High-translucent dental zirconia has been introduced as a suitable material for anterior monolithic restorations. The material composition differs from traditional 3Y-TZP both with regard to yttria content and grain size.

Fracture Resistance of Zirconia Oral Implants In Vitro: A Systematic Review and Meta-Analysis [PDF]

, 2020
Various protocols are available to preclinically assess the fracture resistance of zirconia oral implants. The objective of the present review was to determine the impact of different treatments (dynamic loading, hydrothermal aging) and implant features (

Unveiling the Corrosion Mechanisms of High‐Entropy RETaO4 Through In Situ Observation

Advanced Science, EarlyView.
Composition‐property relationships in multi‐component RETaO4 are unveiled. In situ XRD/TEM and EBSD expose dynamic crystallization pathways of the dominant corrosion product (pyrochlore) and reaction‐diffusion corrosion mechanisms. La1/6Nd1/6Sm1/6Eu1/6Gd1/6Dy1/6TaO4 emerges as the optimal composition, combining minimal corrosion layer thickness with ...

Contact damage in an yttria stabilized zirconia: Implications

Journal of Materials Science: Materials in Medicine, 2007
This paper presents the results of a combined experimental and computational study of contact damage in a 3 mole% yttria partially stabilized zirconia (3-YSZ) that is relevant to hip implants and dental restorations. Contact-induced loading in real applications is idealized using Hertzian contact model to explain plasticity phenomena and failure ...

Enhancing Solid Oxide Fuel Cells Development through Bayesian Active Learning

Advanced Energy Materials, EarlyView.
This article presents an active learning approach using Bayesian optimization to calibrate the multiphase‐field model parameters for simulating the aging of Ni‐GDC anodes in SOFCs. By integrating experimental data and navigating through complex parameter spaces, it enhances predictive accuracy and provides insights into microstructural evolution ...

Delineating the Intricate Impact of Carbon in All‐solid‐state Lithium‐Sulfur Batteries

Advanced Energy Materials, EarlyView.
Solid‐state electrolyte decomposition in sulfur cathodes is quantified with different carbon blends to extract sulfur utilization and conversion efficiency. It is established that higher surface area carbon blends do not always decompose the most electrolyte, and that carbon selection to mitigate active material loss is more effective than selection to

Electrical and Hydrogen Reduction Enhances Kinetics in Doped Zirconia and Ceria: II. Mapping Electrode Polarization and Vacancy Condensation in YSZ

, 2017
Knowing the correlation between grain boundary mobility and oxygen potential in yttria stabilized zirconia (YSZ), we have utilized the grain size as a microstructural marker to map local oxygen potential. Abrupt oxygen potential transition is established

Microwave synthesis of ZrO₂ and yttria stabilize ZrO₂ particles from aqueous precursor solutions [PDF]

, 2012
Zirconia and Yttrium stabilized zirconia are well-known ceramic materials. Scaling down the dimension of these ceramics can result in a faster sintering process at lower temperatures.
