Summary: The focus of this review is on the development of scandia-stabilized zirconia (ScSZ) electrolytes for intermediate-temperature solid oxide fuel cells (SOFCs). The study explores the co-doping control and preparation techniques for improving ionic conductivity and phase stability of ScSZ, with the aim of addressing limitations in the efficient operation of these fuel cells.

Summary: The S-N curve of a composite consisting of ceria-stabilized zirconia (Ce-TZP) and alumina (Al2O3) was measured in this study. The initial bending strength of the Ce-TZP/Al2O3 composite was determined, followed by applying stress above 70% of the initial bending strength for up to 1,000,000 cycles. Transformation bands were formed on the tensile surface, and fatigue failure occurred at the band with the largest width. Post-fatigue heating treatment was effective in removing the transformation bands and enhancing the strength of the material.

Summary: This paper focuses on the continuous measurement of the crystallographic evolution in polycrystalline materials using high-resolution x-ray diffraction. Through observing the structure changes at high temperatures, the characteristics of reciprocal space node splitting and scattering signal evolution during phase transitions are explored.

Summary: The study focused on transformation-induced plasticity in a ceria-stabilized-zirconia based composite, specifically looking at nucleation and growth of tetragonal-to-monoclinic transformation bands. The results showed that the spacing between the bands was influenced by the sample's thickness, with thicker samples leading to a smaller number of larger/deeper bands. Residual stresses around indentations on the tensile surface triggered band nucleation, but did not significantly affect the total number of bands in the end. A stress shielding model suggests that wider bands hinder the propagation of adjacent thinner bands due to stress shielding effects.

Summary: A new paste for stereolithography processing of dense 11Ce-TZP-based composites was developed using a commercial composite powder. The resulting microstructure from stereolithography showed larger strontium aluminate clustering and a matrix of zirconia-alumina grains, leading to greater plastic deformation without compromising strength. This method appears promising for the development of custom-made ceramic prostheses.

Summary: Recent experiments on fast pulse heating of graphite indicate a sharp maximum on the melting curve, prompting a study on extended in-plane defects in graphene which may contribute to the upper limit on its melting temperature. A proposed defect model explains the observed increase in specific heat in slow pulse heating experiments and the lack of such increase in fast pulse heating experiments indicates potential overheating.

Summary: This study discusses the mechanical properties and phase transformation behavior of CNT reinforced 3YSZ composites prepared by spark plasma sintering. CNTs are found to improve fracture toughness and reduce microcracking in the YSZ matrix, leading to enhanced material reliability. The 7 wt% CNT/3YSZ composite exhibits high fracture toughness, making it an attractive option for high-impact, high-temperature applications.

Summary: The study systematically investigates the thermal hysteresis in ZrO2-CeO2 shape-memory ceramics, revealing the impact of CeO2 content on hysteresis through calorimetry measurements and in situ X-ray diffraction analysis. The findings provide insights into the controlling factors of hysteresis in SMCs and clarify previous contradictory reports in the literature.

Summary: By incorporating yttria partially stabilized zirconia into WC-Co cemented carbides, the hardness and fracture toughness can be simultaneously improved, mainly attributed to the stress-induced phase transformation of tetragonal ZrO2. ZrO2 particles dispersed homogeneously in the WC skeleton and had good interfacial bonding with both WC and Co phases, contributing to the enhancement of the mechanical properties of cemented carbides.

Summary: Y2O3 and SiO2 co-doped ZrO2 powders were prepared by co-precipitation method, and the microstructure, phase transformation process, and phase stability were investigated. The results show that increasing the substitution ratio of SiO2 for Y2O3 reduces the tetragonality of the powder and inhibits grain growth.

Summary: This study focuses on the effects of rare-earth dopants on the phase equilibria and phase stability of tetragonal zirconia in ZrO2-RETaO4 systems. The composition range of non-transformable t-ZrO2 in ZrO2-YbTaO4, ZrO2-DyTaO4, and ZrO2-GdTaO4 is measured to be about 30-41, 22-29, and 16-19 mol% RE0.5Ta0.5O2, respectively. However, non-transformable t-ZrO2 cannot be found in ZrO2NdTaO4 and ZrO2-LaTaO4. These findings are valuable for the development of appropriate thermal barrier coatings.

Summary: This study reports a phase-controlled, bendable, ultra-thin 3YSZ electrolyte with high flexural strength and improved ohmic resistance. The highest cell performance among reported flexible SOFCs is achieved using conventional electrodes, with a maximum power density of 0.86 W cm(-2) at 900 degrees C. This study provides a framework for developing flexible SOFCs as next-generation power sources for mobile devices with high volumetric power.

Summary: This study investigated the wettability and tribological performance of zirconia surface by laser irradiation. The results showed that laser parameters had a significant effect on the wettability, with moderate laser power producing the best wettability. Laser irradiation also slightly increased the hardness and reduced the coefficient of friction of dry friction, while increasing the coefficient of friction of wet friction. Additionally, laser-irradiated microstructure effectively enhanced the adhesion of bone to zirconia.
