Summary: The eutectic composites of the ZrO2-PrOx system were studied, with a focus on the sensitivity of their microstructure, phase symmetry, and composition to variations of the processing atmosphere. The results showed that a lamellar, eutectic-like microstructure forms in air, N-2, or 5%H-2(Ar) atmosphere, with the major phase having less Pr content. The Pr concentration in each phase and the PrOx molar percentage of the eutectic composites decrease as the atmosphere becomes more reducing.

Summary: Transparent alumina doped with rare-earth or transition metal oxides is a group of materials suitable for optical applications. The preparation process requires high-quality starting materials, advanced shaping techniques, and pressure-assisted sintering. Spark plasma sintering and hot isostatic pressing have been proven effective in producing pore-free fine microstructures with high in-line transmission and sufficient intensity of light emission. This review aims to summarize and compare published results on this topic, as well as propose other possible and appropriate approaches for future research.

Summary: Ceramics are widely used in engineering applications due to their unique properties, but their high hardness and brittleness make traditional machining difficult. Electrical discharge machining is considered a method for machining non-conductive ceramics. However, current results of ceramic machining using electrical discharge still fall short of expectations.

Summary: Multiple sialon ceramics compositions were synthesized using nanosized metal oxides (MOs) as additives in the oxynitride network. The formation of alpha-sialon and its properties were investigated, with the samples showing high relative densities and Vickers hardness values, along with variations in fracture toughness and thermal conductivity based on the type of MO used.

Summary: This paper provides a comprehensive review on the basic principles, advanced solidification processes, microstructure, and mechanical properties of nanocrystalline alumina-zirconia-based eutectic ceramics. It discusses the coupling growth principle, solidification techniques, and control strategy of solidification behavior. The microstructural formation of nanoeutectic structure and the mechanical properties, such as hardness, flexural and tensile strength, fracture toughness, and wear resistance, are also emphasized. Nanocrystalline alumina-zirconia-based eutectic ceramics with unique microstructural and compositional characteristics have shown promising improvements in mechanical performance compared to conventional eutectic ceramics.

Summary: Deep eutectic solvents (DESs) have been investigated for the leaching of rare-earth metals, and it was found that mechanical activation can significantly enhance the leaching efficiency. The leaching process was found to change from chemical reaction controlled to diffusion controlled after mechanical grinding. This study proposes an eco-friendly and sustainable alternative for conventional leaching and solvent, which shows great potential for the recycling of rare-earth metals.

Summary: This study investigates the effect of different types of rare-earth (RE) oxide doping on the crystal structure, mechanical properties, and thermal properties of La2(Zr0.7Ce0.3)2O7 (LZC) ceramics. The results show that all five ceramics have a single pyrochlore phase structure, with reduced lattice constants after doping. Rare-earth doping does not affect the grain growth of LZC, but significantly improves its hardness. Furthermore, RE doping, especially with Gd3+, greatly reduces the thermal conductivity of LZC ceramics.

Summary: The rattler effect caused by Yb3+ doping can effectively reduce the thermal conductivity of rare-earth zirconate ceramics. Ceramics with dual-phase structure exhibit enhanced hardness, high coefficient of thermal expansion, and potential as promising thermal barrier coatings due to the active resonant scattering center role of Yb3+.

Summary: Rare earth elements are important for green energy technologies, but are considered critical raw materials. Electric field assisted mining using biodegradable electrolytes, such as organic acids, shows potential as an eco-friendly alternative for metal extraction. The selectivity of different electrolytes varies, with organic acids achieving better results compared to deep eutectic solvents.

Summary: This study compares a filament-based free wake panel method to experimental and validated numerical data in order to simulate propeller slipstreams and their interaction with aircraft components. The results show that the free wake panel method is able to successfully capture the slipstream deformation and shearing, making it a useful tool for propeller-wing interaction in preliminary aircraft design.
