Special Issue Information

Dear Colleagues,

Recent advances in materials science have enabled the development of high-performance functional materials with diverse applications in electronics (including semiconductors), energy storage, sensors, and communication systems. This Special Issue aims to gather cutting-edge research focused on the design, synthesis (via solid-state or solution-based methods), characterization (XRD, SEM, TGA, Raman, XPS), and applications of advanced dielectric and multifunctional materials.

Topics of interest include, but are not limited to, dielectric ceramics, complex oxides, composites, ferroelectric materials, and systems exhibiting non-Debye relaxation behavior.

Special emphasis will be placed on studies that highlight the relationships between composition, structure, and properties; the enhancement of material stability and performance; and the use of innovative processing techniques. Contributions based on experimental, theoretical, or computational approaches are welcome, as are studies exploring emerging applications such as 5G technologies, capacitive energy storage, microwave devices, and flexible electronics.

This Special Issue aims to foster interdisciplinary dialog and showcase current trends in materials science, encouraging collaboration among researchers in physics, chemistry, and materials engineering. We invite academics and industrial scientists to submit original research articles, reviews, or communications that contribute to the advancement of functional materials.

Over more than half a century of using zirconia in technology and industry, researchers have faced several challenges related to the performance of this material. It is believed that some issues regarding the low performance of the zirconia ceramics can be solved by using a multidoping strategy. In this study, nanoparticles with the composition (1 − x)⸱ZrO2 − x⸱MD (where MD—multi-dopant Y:Ce:Mg:Ca with cation relationship 1:1:1:1 and x = 0.05–0.25 mol. %) were synthesized using a hydrothermal method followed by annealing. XRD and Raman spectroscopy analyses demonstrated that in the concentration range of x = 0.10–0.25 mol.%, the only detectable phase in the synthesized samples was the tetragonal phase of zirconia. SEM analysis revealed that the size of the final particles ranged from 20 to 50 nm. It was demonstrated that using obtained nanoparticles as precursors for sintering leads to the formation of multiphase ceramics. The microhardness and biaxial flexural strength of the ceramic samples vary depending on the dopant concentration in the range of 600–1400 HV and 25–200 MPa respectively. Mechanical properties mostly depend on porosity and grain size in the sintered material. The study shows that the multidoping strategy has high potential to obtain new constructional ceramics and components for solid oxide fuel cells. Full article
