Summary: In this study, cobalt ferrite/barium titanate particulate composites with high magnetoelectric coefficients were synthesized using mechanical ball milling and high-temperature annealing. The use of 50 nm cubic BaTiO3 powder as a precursor resulted in a composite with a magnetoelectric coupling coefficient value as high as 4.3 mV/Oe cm. The Microstructure of these composites differs significantly from those synthesized using 200 nm tetragonal BaTiO3 powder, showing larger CoFe2O4 grains and better electrical insulation due to the surrounding BaTiO3 matrix.

Summary: The coupling of the piezoelectric effect and photocatalytic process promoted the separation of photogenerated carriers, thus increasing the piezo-photocatalytic activity. BaTiO3 nanoparticles were prepared on the Ti3C2Tx surface, and the obtained BaTiO3/Ti3C2Tx piezo-photocatalysts exhibited rapid electron transfer and a wide visible light response range. These results demonstrate that coupling piezoelectric and photocatalytic properties has broad application prospects in water pollution control.

Summary: This study successfully synthesizes various forms of BaTiO3, including octahedra, edge- and corner-truncated cubes, and cubes with four tunable sizes. Acetic acid treatment removes BaCO3 impurities, and Rietveld refinement confirms the crystal structure is tetragonal. The crystals' physical properties vary with their size and facet. BaTiO3 octahedra exhibit better performance than truncated cubes and cubes, especially in piezoelectric nanogenerators.

Summary: Porous alloy nanomaterials are important for various applications, and the evolution of individual AuAg alloy NPs during chemical and electrochemical etching processes is tracked using in situ liquid phase transmission electron microscopy. The electrochemical etching method produces NPs with more uniform pore sizes and allows for tuning the NPs porosity by modulating the electrochemical potential. The formation of an Au-rich passivation layer on the surface of NPs at initial stages of etching is critical in preserving the NP's porous shell as pores form underneath this layer during the etching process.

Summary: The effects of different proportions of hydrothermal medium composition on the hydroxylation process were explored to obtain high tetragonality in tetragonal barium titanate (BT) powders. The optimal solvent condition of water:ethanol:ammonia solution of 2:2:1 resulted in a BT powder with a high tetragonality of 1.009, which increased with the particle size. The uniformity and dispersion of BT powders with particle sizes of 160, 190, 220, and 250 nm were improved by the inhibition of ethanol on the interfacial activity of BT particles (BTPs). The core-shell structure of BTPs was revealed, explaining the relationship between tetragonality and average particle size.

Summary: In this study, high tetragonality BaTiO3 (BT) powder with controllable dispersion and particle size was successfully synthesized using a two-step hydrothermal method and combined dispersants, namely cetyltrimethylammonium bromide (CTAB) and polyvinyl-pyrrolidone (PVP). The synergistic effect of chemical bond force and electrostatic adsorption force between these dispersants at high temperature resulted in the achievement of ultrafine BT powder with high c/a ratio, small size, and low polydispersity index. This approach is of great significance for synthesizing BT powder with high tetragonality, high dispersion, and small particle sizes.

Summary: Earth-abundant transition metal oxides, such as CoO and Co3O4, grown on carbon fiber paper (CFP) electrodes, exhibit different catalytic activities for the oxidation of glycerol, diols, and monohydric alcohols. In situ electrochemical tests show that the CoO/CFP electrode has higher catalytic activity than the Co3O4/CFP electrode, with lower interfacial impedance, higher charge transfer, and faster oxidation rate. The CoO/CFP electrode also produces value-added products with high selectivity and efficiency at low energy consumptions. Theoretical calculations highlight the importance of octahedrally coordinated Co-O sites in the adsorption, activation, and oxidation of C3-C1 alcohols. These findings provide insights for the design of highly efficient transition metal oxide catalysts for alcohol oxidation.
