Summary: Shape memory materials are smart materials that can generate recoverable residual deformation, with shape memory ceramics being more suitable for extreme conditions. This study demonstrated the shape memory behavior of ferroelectric ceramics, showing that they are more suitable for SMC applications at medium stress levels due to their smaller critical stress compared to zirconia-based SMCs.

Summary: Defect-induced semiconducting ferroelectric oxides enable the classic ferroelectric Bi0.5Na0.5TiO3 (BNT) to have a low bandgap while maintaining ferroelectricity and enhancing its photovoltaic output. A series of ferroelectric semiconductor materials (1-x)Bi0.5Na0.5TiO3-xBaNb(0.5)Zn(0.5)O(3-delta)(BNT-BZN) with photovoltaic effects were successfully synthesized. The optical bandgap of BNT was slightly reduced to 2.51 eV by non-equilibrium stoichiometric defects and interstitial ions in the BZN-modified BNT ceramic. The semiconducting BNT-BZN ceramics exhibit potential applications in photovoltaic devices and photoelectric conversion.

Summary: Lead-free relaxor ferroelectric materials show great potential in pulsed power capacitors due to their high power density, operational stability, fast charge/discharge rate, and environmental friendliness. The addition of Bi(Mg0.5Zr0.5)O-3 improves the relaxor ferroelectric characteristics and dielectric breakdown strength by forming fine grain sizes and reducing oxygen vacancy concentrations. It provides promising material system for power pulse devices.

Summary: Enhanced pyroelectric response was achieved in lead-free KBT-BT-NBT ceramics through domain engineering and texture along the [001] crystallographic direction. X-ray diffraction analysis indicated a high degree of texture (93%) along [001]. These textured ceramics exhibited comparable pyroelectric figures of merit to lead-based materials at room temperature, and a significant enhancement in pyroelectric response at depolarization temperature due to coherent domain switching.

Summary: This study investigates the key aspects of synthesizing NBT-BT-KNN ceramics to achieve high S-max/E-max values, by destabilizing the ferroelectric order in the material through changing the composition. Results indicate that Na or Ti deficiency, or excess of Bi can decrease the ferroelectric-to-relaxor transition temperature and remnant polarization.

Summary: Ferroelectric ceramics with enhanced photovoltaic performance were prepared by utilizing conventional solid-state sintering strategies. The defect-induced bandgap intermediate state derived from the split state of Ni plays a dominant role in lowering the bandgap of KN, promoting light absorption and carrier separation. Among these ceramics, KNBNH6 shows the highest short-circuit photocurrent density (J(sc)) of 138.7 nA/cm(2) and is further enhanced to 702.9 nA/cm(2) after polarization. The polarization induced lattice distortion in KNBNH6 increases the polarity of its cells, enhancing its photovoltaic properties.
