Strategy of Sintering Ceramics Under Extreme Conditions

Interdisciplinary Materials, EarlyView.
Novel strategies in extreme sintering technologies, which include ultrafast sintering, strong electric field‐assisted sintering, high‐pressure and ultra‐high‐pressure sintering, and multi‐field assisted sintering, and so on. ABSTRACT Advanced ceramics play a critical role in high‐tech industries.

Hole Polaronic Confinement in (111) Yttria‐Stabilised Zirconia

Small, EarlyView.
Ultrathin epitaxial YSZ(111) films unexpectedly develop p‐type mixed conduction and amplified electromechanical coupling under oxidizing conditions. Combined transport measurements and first‐principles modeling reveal that nanoscale confinement and ordered dopant–vacancy complexes stabilize localized O 2p hole polarons at the surface. A canonical ionic

Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

steel research international, EarlyView.
This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Water sorption of dental resin composites: Is a new method the future?

European Journal of Oral Sciences, EarlyView.
Abstract Intraoral, diffusion‐controlled water sorption leads to dimensional expansion and mechanical degradation over time. Measurement of small quantities of water in dental resin composites (RCs) is challenging, as current techniques rely on weighing approaches. Here, we evaluate Karl‐Fischer Titration (KFT) and thermogravimetry (TG) as alternatives

Fatigue Performance and Failure Loads of Composition‐Gradient Multilayer Zirconia: Partial‐Coverage Restorations Versus Single Crowns at Different Thicknesses

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This study investigated the influence of restoration type (partial‐coverage versus crown) and ceramic‐layer thickness on the fatigue behavior and failure load of monolithic composition‐gradient multilayer zirconia (4Y‐PSZ/5Y‐PSZ) molar restorations. Material and Methods Seventy‐two CAD/CAM‐fabricated monolithic zirconia restorations (

Effect of Y2O3-addition on the crystallographic and mechanical properties of the Ce-TZP/Al2O3 composite [PDF]

Cerâmica
The effect of adding different Y2O3 contents on the physical and mechanical properties of Ce-TZP/Al2O3 composites was investigated. Ce-TZP/Al2O3 powder blends containing 1~10 wt% Y2O3 were compacted at 100 MPa-30 s and sintered at 1500 °C-2 h or 1600 °C ...

Translucency of 3D‐Printed 3Y‐ and 5Y‐Doped Zirconia

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate and compare the translucency of 3D‐printed zirconia materials: 3Y tetragonal zirconia polycrystal (3Y‐TZP) and 5Y partially stabilized zirconia (5Y‐PSZ). Material and Methods 3D‐printed 5Y‐PSZ and 3Y‐TZP materials fabricated using digital light processing (DLP) were investigated.
