Summary: By adding CuO sintering aid, excellent electrical properties including piezoelectric response, remanent polarization, and high-temperature ferroelectric Curie point can be achieved in CaBi2Nb2O9 ceramics synthesized through the conventional solid-state technique. The adjustment of microstructural and domain configuration further enhances the electrical properties of CaBi2Nb2O9, making this simple textured approach suitable for the development of high-performance and high-temperature piezoelectric ceramics.

Summary: This study innovatively utilizes the VPP technique to fabricate highly textured and 3D-structural barium titanate piezoelectric ceramics. Compared to random ceramics, printed textured barium titanate ceramics exhibit smaller dielectric permittivity, larger piezoelectric coefficient, significantly increased piezoelectric voltage coefficient g33 and figure of merit d33xg33, and improved piezoelectric output performance.

Summary: In this study, high piezoelectric properties and superior thermal stability were achieved by high-temperature poling in a 0.4 mol% ZnO-doped ceramic material. The high-temperature poling method formed a small-sized and highly oriented domain structure, effectively improving the piezoelectric and dielectric properties. The enhanced pinning effect of defect ions and stabilized domain structure due to high-temperature poling also contributed to the superior temperature stability of the piezoelectric and dielectric properties.

Summary: In this study, pure phase BS-PT nanofibers were successfully synthesized by optimizing the concentration of the electrospinning additive and the sintering temperature. The BS-PT nanofiber piezoelectric sensor showed a stable sensitivity above 4 V/N in the temperature range of 60-200 degrees C and at frequencies of 10-40 Hz. Furthermore, the sensor exhibited a nearly linear output voltage with increasing excitation pressure in the range of 0.07 N to 0.55 N at temperatures of 160-260 degrees C, and the sensitivity at 220 degrees C was still higher than 5.4 V/N. These findings suggest that the BS-PT nanofiber piezoelectric sensor holds great promise for high-temperature pressure and vibration measurements.

Summary: This study investigates the microstructure and texture evolution mechanism of ultra-high-strength non-oriented silicon steel to find the process equilibrium point between its mechanical properties and magnetic properties. The results show that by increasing the annealing temperature, the recrystallization ratio and iron loss of the steel gradually improve, while the yield strength decreases. The Goss texture strengthens and the gamma-fiber weakens, while the lambda-fiber texture strengthens slowly. The study identifies the annealing temperature of 710 degrees C as the optimal condition, as it meets both the magnetic properties and strength requirement of the generator set.
