Summary: In this work, Bi non-stoichiometry is used to optimize the photostriction performance by controlling the oxygen vacancy concentration and the ferroelectric to relaxor phase transition temperature. The increase of Bi non-stoichiometry decreases the oxygen vacancy concentration, allowing for more effective interaction between the photo-generated carriers and the lattice, resulting in large photostriction and high photostriction efficiency. Moreover, the Bi non-stoichiometry induces the decrease of the TF-R and the decoupling of the A-O bond, which increases the polarizability of the unit cell and optimizes the photostriction macroscopically.

Summary: The substitution of aliovalent elements at either the A- or B-site of ferroelectric perovskites has a significant impact on their properties. Donor doping leads to softening of ferroelectrics, while acceptor doping results in hardening. This review focuses on doped-BaTiO3, a lead-free ferroelectric model, and examines the effects of aliovalent doping on its dielectric, ferroelectric, and piezoelectric properties, using Cu (acceptor) doping as an example.

Summary: This study investigated the impact of variations in different cation compositions on the phase composition, microstructure, and microwave dielectric properties of Y3+xAl5O12 ceramics. It was found that Al2O3 precipitated in Al-excess samples while YAlO3 secondary phase appeared in Y-excess samples, leading to an increase in lattice parameters. Additionally, a small amount of Y2O3 was found to promote continuous phase boundaries and facilitate the release of internal stresses.

Summary: An ultrahigh energy storage density and large efficiency are achieved in high-entropy lead-free relaxor ferroelectrics, nearly ten times higher than low-entropy material. This is attributed to the enhanced random field, decreased nanodomain size, strong multiple local distortions, and improved breakdown field. The high entropy strategy demonstrates the effective design of high-performance dielectrics, advancing the development of advanced capacitors.

Summary: The development of lead-free (K, Na)NbO3(KNN)-based materials with excellent piezoelectric properties is important due to their environmental friendliness and potential for device applications. This study focuses on the exploration of the electrostrictive effect potential in KNN-based piezoelectric materials, specifically (1-x)K0.5Na0.5NbO3-xBi0.5Na0.5ZrO3 (KNN-xBNZ), by enhancing the relaxor characteristic through introducing a high content of BNZ.

Summary: In this study, a record-high electrostrictive coefficient of approximately 0.0712 m(4) C-2 was achieved in lead-free BaTiO3-based ceramics through a polarization nanocluster design, along with hysteresis-free strain and excellent frequency and thermal stabilities. The introduction of Li+ and Bi3+ into the BaTiO3 lattice matrix breaks the long-range ferroelectric ordering and forms polarization nanoclusters, resulting in a relaxor state with suppressed polarization and maintained electro-strain.

Summary: This study developed high-temperature dielectric materials based on Bi0.5Na0.5TiO3 (BNT) near the morphotropic phase boundary, which exhibit excellent energy storage performance. The random distribution of polar nanoregions induced by composition modulation disrupts the long-range dipolar alignment and weakens the coupling between ferroelectric domains, resulting in slender and deferred polarization-electric field hysteresis loops with relatively high saturation polarization. The relaxors in this study demonstrate reversible nano-domain orientation and growth, leading to negligible remnant polarization and superior energy storage properties, outperforming state-of-the-art dielectric energy storage materials under similar conditions.

Summary: This work investigates the influence of the preparation process on the structure and conduction mechanisms of Bi0.5Na0.5TiO3 (BNT)-based complexes. It is found that the ceramics prepared by tape-casting exhibit a rutile titanium dioxide phase, while the ceramics prepared by conventional solid-state reaction show a pure perovskite phase. The ac impedance spectra reveal different conductive behaviors in the two preparation routes. This study highlights the importance of the preparation route in the structure and conduction mechanisms of BNT-based oxide ionic conductive materials.

Summary: This study investigated the structural, dielectric, and ferroelectric properties of lead-free ceramics based on the ternary system of BaTiO3 (BT). It was observed that the dopant concentration influenced the structural evolution from tetragonal to pseudocubic phase. The dielectric response showed diffusive peaks and relaxor behavior, indicating a transition from ferroelectric to relaxor state. The ceramics exhibited slim polarization hysteresis loops and electrical inhomogeneities caused by excessive dopant addition, leading to degraded electric breakdown strength. The oxygen vacancy hopping mechanism was proposed to explain the diffuse dielectric response at high dopant concentrations.

Summary: Extensive research has revealed that oxygen evolution reaction (OER) in alkaline conditions involves dynamic surface restructuring. The development and design of sulfide/oxide pre-catalysts can reasonably adjust the composition and structure after surface reconstruction, which is crucial for OER. This study utilized a simple two-step hydrothermal method to achieve in situ S leaching and doping, inducing the composition change and structure reconstruction of CoFe oxides. The transformed FeOOH and CoOOH exhibited excellent OER activity and could be easily mass-produced using low-cost iron based materials and simple methods.

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

The Y-Ti-Ta-O nano-oxides were found to be mainly Y2(Ti,Ta)2O7, with an average size of 7 nm and a number density of 6.8 x 1023 m-3. Excess boron was found to enhance the adhesion of some low-sigma grain boundaries but weaken the Fe/Y2Ti2O7 interface, while excess tantalum enhanced the Fe/Y2Ti2O7 interface but caused serious degradation of grain boundaries.
