Summary: Zirconia and zirconia-yttria solid solution powders were successfully precipitated and crystallized under hydrothermal conditions. The morphology and phase composition of the obtained powders were found to be strongly influenced by the Y2O3 concentration, with low Y2O3 content leading to elongated particles and high Y2O3 content resulting in isometric particles.

Summary: Carbon spheres (CSs) were synthesized from glucose using the hydrothermal carbonization method. The concentration of glucose used in the synthesis process was varied to study its effect on yield, morphology, and electrochemical capacitance of the CSs. Two post-synthesis procedures, heat treatment at 800 degrees C and sulfonation with subsequent heat treatment, were performed on the CSs. The synthesized samples exhibited large agglomerates of CSs with a three-dimensional network of microspheres and other irregular shapes. Despite the reduction in specific surface area, these agglomerates showed good electrochemical capacitance due to the creation of mesopores and facilitated ion insertion during charging and discharging processes.

Summary: Silicon carbide materials are excellent candidates for high-performance applications due to their outstanding thermomechanical properties and corrosion resistance. The oxidation behavior of SiC depends on temperature and time, and wet oxidation can accelerate the process. Hydrothermal media have an impact on SiC materials, which has been explained by different models.

Summary: The purpose of this review paper is to describe the Growing Integration Layers (GIL) method for coating biocompatible oxide ceramics layers on metallic alloys. The GIL method allows for the growth of oxide layers on the substrate alloy from the bottom, resulting in chemically and structurally continuous layers with excellent adhesion. This method enables the processing of functional and structural ceramic layers in aqueous solutions, providing a soft and green process with low energy consumption. The GIL strategy has been successfully applied to coat bioactive hydroxyapatite ceramics on titanium-based metallic alloys, improving adhesion and introducing bioactivity.

Summary: The stability of aliovalent ions in ionic crystals is closely related to lattice site potential and Madelung electrostatic potential. The formation of perovskite structure type compounds can be energetically favorable with higher Madelung electrostatic potential compared to parent binary compounds. Strong lattice site potential results in stability of high valence ions, with some experiencing maximum lattice site potential at specific lattice sites. Analysis of lattice site potential and Madelung electrostatic potential can rationalize the stability or instability of certain compounds with uncommon valence states.
