(1 − x)Ba0.95Ca0.05Ti0.94Zr0.06O3-(x)Dy (x = 0-0.90 mol%) lead-free ceramics were prepared at 1190 °C with as-synthesized nanoparticles via a modified Pechini polymeric precursor method. X-ray powder diffraction, Raman spectrometer, and X-ray photoelectron spectroscopy were used to investigate the phase, symmetry, and valence state, respectively. The results indicated dysprosium could induce the phase transformation from O to R. The mechanism of defect complexes and oxygen vacancies that influenced by various dysprosium contents were discussed in detail. The results of dielectric, ferroelectric, and piezoelectric characteristics suggested the electrical properties were initially elevated with a trifling addition of dysprosium contents, and then decreased with further increased x. Moreover, reasons for diversified electrical properties, i.e., imbalanced long-range and short-range forces, changed octahedron structure, defect dipole, pinching effects of domain wall and element electronegative, were all stated in detail. The optimal physical properties, d33 = 371 pC/N, Qm = 87, and CTE2 = 1.23 × 10−5 K−1, were detected at x = 0.60 mol%, and those findings were regarded as prospect in the development of lead-free ferroelectric ceramic materials.

The Bio-Analytic Resource for Plant Biology ('the BAR', at https://bar.utoronto.ca) is celebrating its 20th year in operation in 2025. The BAR encompasses and provides visualization tools for large 'omics data sets from plants. The BAR covers data from Arabidopsis, tomato, wheat, barley and 29 other plant species (with data for 2 others to be released soon). These data include nucleotide and protein sequence data, gene expression data, protein-protein and protein-DNA interactions, protein structures, subcellular localizations, and polymorphisms. The data are stored in more than 200 relational databases holding 186 GB of data and are presented to the researchers via web apps. These web apps provide data analysis and visualization tools. Some of the most popular tools are eFP ('electronic fluorescent pictograph') Browsers, ePlants and ThaleMine (an Arabidopsis-specific instance of InterMine). The BAR was designated a Global Core Biodata Resource in 2023. Like other GCBRs, the BAR has excellent operational stability, provides access without login requirement, and provides an API for researchers to be able to access BAR data programmatically. We present in this update a new overarching search tool called Gaia that permits easy access to all BAR data, powered by machine learning and artificial intelligence., (© The Author(s) 2024.
