Summary: In this study, high-resolution simulations and a phase-field model were used to analyze the ferroelectric domain evolution in PZT and its impact on material properties. By automatically identifying and tracking different types of domain walls, their role in polarization reversal process was studied. The results reveal correlations between the density and width of domain walls and macroscopic piezo- and dielectric material properties. Furthermore, correlations between the average polarization and strain within a grain and its crystallographic orientation were observed, in agreement with experimental results.

Summary: Lead zirconate titanate (PZT)-based piezoelectric ceramics with increasing average grain size were prepared and their properties were systematically investigated. The results showed that the electromechanical properties of the ceramics improved significantly with increasing grain size. In addition, the formation of non-180 degrees domain walls was suppressed in the fine-grain samples, while enhanced domain wall mobility was observed in the coarse-grain samples. This study confirmed that grain size engineering is an effective strategy for designing piezoelectric materials with excellent combination properties.

Summary: The defects in acceptor-doped perovskite piezoelectric materials have a significant impact on their electrical properties. The defect-mediated evolution of piezoelectric and ferroelectric properties in Fe-doped (Pb,Sr)(Zr,Ti)O-3 (PSZT-Fe) piezoceramics was systematically investigated using different treatments. Different defect states result in different ferroelectric and piezoelectric properties, with aged PSZT-Fe polycrystals showing reversible domain switching and recoverable strain effect.

Summary: The crystallization evolution of lead zirconate titanate (PZT) powders processed from two organic gel systems was investigated, showing that the perovskite PZT form began to crystallize as the calcining temperature reached 400 degrees C and the crystallization mechanism was related to the powder precursor system. The activation energy for perovskite formation was approximately 77 kJ mol(-1) regardless of the precursor system when the Kissinger model was applied.

Summary: Under the application of an external voltage, high electric field concentrations develop around the interdigitated electrode edges inside multilayer ceramic actuators (MLCAs). The local inhomogeneity in the electromechanical response is caused by the spatial distribution of the local electrical field. By utilizing synchrotron-based high-energy X-ray diffraction (XRD), the structural changes in partially electroded Nb-doped PbZrxTi1-xO3 samples as a function of applied electric field were investigated. The results show that the domain switching behavior and phase transitions are spatially dependent across the inactive regions in partially electroded samples, especially near the electrode edge and the tetragonal composition near the morphotropic phase boundary (MPB).

Summary: This work investigates the laser-based annealing process of sol-gel-derived PZT53/47 thin films and demonstrates that the crystallization time of chemical solution deposited PZT thin films can be significantly reduced by using laser radiation. The study also reveals that short interaction times during laser annealing shift the nucleation of the PZT thin films from epitaxial to heterogeneous nucleation.

Summary: Asteroid 4 Vesta is believed to be the parent body of howardite, eucrite, and diogenite (HED) meteorites, which likely represent different layers of Vesta. There are similarities between HEDs and mesosiderite meteorites, suggesting a potential link between the two groups. The study used lead-lead (Pb-Pb) dating to analyze the ages of melt clasts in eucrites and phosphates in mesosiderites. The results indicate major heating events on the parent body of eucrites and a period of increased impact flux on the mesosiderite parent body. These findings support the hypothesis of multiple parent bodies for HEDs and mesosiderites.

Summary: Ba(Fe0.7Ta0.3)O3-delta (BFTO) compounds were synthesized with varied sintering temperatures, affecting their crystal structure, electronic structure, and electrocatalytic activity. The chemical environment of Fe and Ta cations in BFTO is significantly influenced by the processing temperature, impacting the electrocatalytic performance of the compound. The electrochemical catalytic activity of BFTO shows improvement with increasing sintering temperature, potentially due to enhanced structural quality.

Summary: An in-depth understanding of charge transfer processes at electrochemical interfaces is crucial for the design of energy storage materials. X-ray photoelectron spectroscopy plays a vital role in analyzing electronic structures of heterogeneous interfaces. Ex situ studies fail to capture intermediate and transient species, impeding a predictive understanding of the charge transfer process. Overcoming technical limitations, considerable progress has been made in in situ/operando x-ray analysis of buried interfaces. This review summarizes recent advances in the application of in situ and operando x-ray photoelectron spectroscopy for characterizing interfacial processes and discusses remaining challenges and future research directions.

Summary: The functionalization of GO membranes with ILs provides a promising approach for efficient ion separation and critical material recovery. The ILs in the membranes act as spacers, reducing cation mobility and promoting ion desolvation, resulting in an increased water flux. The high separation efficiency of the IL/GO membranes is attributed to the synergistic modification of hydrophobicity and surface charge.

Summary: This study reports on the investigation of the microstructure, changes in chemical bonding induced by dopants, and electronic structure and chemical valence states of cations in Sn-incorporated gallium oxide. The results show that the incorporation of Sn significantly affects the microstructure and electronic structure of the Ga2O3 compounds. XPS and EDS analyses confirm the presence of SnO2 secondary phase in the samples with higher Sn-content. The FTIR spectroscopic analysis reveals a stronger interaction between Sn and Ga2O3 for higher Sn-content.

Summary: The enhanced safety, superior energy, and power density of rechargeable metal-air batteries make them ideal for energy grids and electric vehicles. However, the lack of a cost-effective and stable bifunctional catalyst has hindered their widespread adoption. This study demonstrates that tin-doped beta-gallium oxide can efficiently catalyze oxygen reduction and evolution reactions, making it a promising cathode material for zinc-air batteries. Experimental and theoretical analysis reveal that the Lewis acid sites in beta-gallium oxide play a crucial role in enhancing the electrocatalytic activity of the tin-doped catalyst.
