Summary: The influence of solid content on the pore morphology and mechanical and piezoelectric properties of porous BCZT ceramics was systematically investigated. The results showed that an increase in solid content led to a decrease in porosity and pore size, an increase in ceramic connectivity, and an increase in compressive strength. The best ferroelectric performance was achieved at a solid content of 30%, while the relative dielectric constant and piezoelectric constant increased with an increase in solid content. At a solid content of 20%, the maximum values of g33 and FOM33 were obtained.

Summary: A design strategy inspired by Kirigami/Origami was proposed for the preparation of curved and porous piezoelectric ceramics with specific shapes. The ceramics produced using this strategy exhibit a high piezoelectric constant and are well-suited for use in the human body to detect pulse signals. This strategy provides a new approach for the large-scale and low-cost production of complex-shaped ceramics.

Summary: This study investigates the aging behavior of BCZT ceramics synthesized through the solid-state process, finding that stresses generated during processing are subsequently relaxed over time, leading to changes in piezoelectric and dielectric properties. By measuring the variations in piezoelectric and dielectric properties, as well as analyzing changes in crystal structure, a deeper understanding of the aging behavior of ceramic materials can be achieved.

Summary: Multi-layer ceramic capacitors with high recoverable energy storage density and large energy efficiency play a crucial role in modern electronic devices. Various ferroelectric ceramic materials with relaxor characteristics and large dielectric constant are the most favorable candidates for achieving superior energy storage performance. In this study, a novel lead-free (1-x)Ba0.80Ca0.20TiO3-x(Bi0.80Mg0.20)(Ti0.65Mg0.30)O-3(BCT-BMT) ceramic material was prepared using a two-stage mechano-chemical activation technique. BMT substitution in Ca modified BaTiO3 resulted in substantial improvement in microstructural characteristics and energy storage performance compared to pure BCT. Introduction of BMT in BCT transformed it into relaxor ceramics, essential for high recoverable energy storage density and energy efficiency. The composition 0.65BCT-0.35BMT exhibited typical relaxor characteristics, large breakdown strength, and a significantly large dielectric constant, achieving an ultra-high recoverable energy density of 3.09 J cm(-3) with a moderately high energy efficiency of approximately 80.15%.

Summary: Hexagonal manganites, RMnO3, show potential for air separation with their reversible oxygen storage and release properties. However, the slow kinetics of oxygen exchange at low temperatures limits their efficiency. This study demonstrates that the oxidation kinetics of RMnO3 can be improved through Ti4+ doping and increasing the rare earth cation size, resulting in enhanced oxygen absorption rates.

Summary: Hexagonal manganites, RMnO3 (R = Sc, Y, Ho-Lu), exhibit reversible oxygen storage and release at temperatures of 150-400°C. The properties of oxygen storage can be controlled by varying R (3+) cations, aliovalent dopants, and crystallite sizes in the nanometer range. This study investigated nanocrystalline RMn1-x Ti (x) O-3 (R = Y, Ho, Dy; x = 0, 0.15) for oxygen absorption using thermogravimetric analysis (TGA) and high-temperature X-ray diffraction (HT-XRD) in O(2) and N-2 atmospheres. The results showed that the oxygen storage capacity increased with Ti4+ dopants and smaller crystallite sizes, along with improved thermal stability and absorption kinetics.

Summary: Piezoelectric ceramics are being considered as stimulating materials for load-bearing applications in living organisms. Developing ceramic films on medically accredited metals is a promising approach to compensate for their brittle nature. Aerosol deposition allows for the production of highly dense thick films at room temperature, however, a thermal annealing step is needed to enhance their functional properties.
