Summary: The choice of temperature and gas conditions in a water pressure-controlled reactor is guided by DFT to synthesize nearly phase-pure lanthanide scandate nanoparticles. Low water-vapor partial pressures inhibit particle growth, while excess water vapor leads to undesired rare-earth hydroxide and oxyhydroxide secondary phases. The optimal humidity for high-purity LnScO3 particle synthesis varies with the lanthanide, and DFT is used to calculate the thermodynamics of secondary phase formation to maintain phase purity (>96 mol %) across the series. The combination of thermodynamic calculation and experimental confirmation enables exploration of analogous syntheses of other inorganic perovskite nanoparticles.

Summary: The hydrothermal approach was utilized to control the particle size, aggregation stage, and composition of PbZrxTi1-xO3 (PZT) particles. The results showed that the size and composition of PZT particles were determined by the ratio of KOH with respect to Pb, rather than the absolute KOH concentration. In a specific ratio range, the PZT particles adopted a cube-like shape, with the size decreasing as the ratio decreased. The crystal structure of PZT changed gradually from rhombohedral to tetragonal with an increase in the Zr/Ti ratio.

Summary: We compared the microstructure and energy-storage properties of (Bi1/2K1/ 2)0.5Sr0.5TiO3 ceramics prepared via solid-state and hydrothermal reactions. The hydrothermally derived ceramics exhibited well-dispersed cubic nanoparticles, while the solid-state reaction resulted in the aggregation of primary particles. By controlling the sintering temperature, the grain size of the hydrothermally derived ceramics could be controlled between 273±24 and 936±69 nm, maintaining a relative density of over 95%. On the other hand, ceramics prepared via the solid-state reaction did not fully densify even at the highest tested sintering temperature of 1200 degrees C. The hydrothermally derived ceramics exhibited a high recoverable energy-storage density of 2.25 J/cm^3 at 240 kV/cm, attributed to their dense and fine-grained microstructure.

Summary: In this study, electrically switchable persistent spin texture (PST) was achieved in a new 2D perovskite ferroelectric material. The mechanism behind this phenomenon was found to be related to the ferroelectric properties and spin-orbit interaction. The direction of spin texture could be reversibly switched by changing the tilting of PbBr6 octahedra and the reorientation of organic cations. This discovery provides a new platform for electrically controlling spin texture.

Summary: Inorganic relaxor ferroelectric solid solution single crystals have superior properties that make them suitable for high performance electromechanical devices. However, relaxor ferroelectric single crystals found in organic-inorganic hybrid perovskites are limited, but achieving these properties in them is significant for functional materials design. Fortunately, the first two-dimensional (2D) organic-inorganic hybrid relaxor ferroelectric single crystal, [Br(CH2)(3)NH3](2)PbBr4 (BPA(2)-PbBr4), demonstrates some of these superior properties, including large relaxation temperature change, low energy loss, and strong second harmonic generation effect. It also exhibits temperature-dependent luminescence with adjustable emitted light color, making it compatible with relaxor ferroelectricity.

Summary: This study focused on the fabrication of wound healing ferroelectric membranes doped with zinc oxide nanoparticles using the electrospinning technique. By adjusting the ratio of vinylidene fluoride-tetrafluoroethylene copolymer and polyvinylpyrrolidone, the properties of the membranes could be controlled effectively, leading to changes in crystallization behavior and antibacterial properties towards Staphylococcus aureus. In vivo experiments showed that ferroelectric hybrid membranes containing a certain proportion of PVP had the best wound-healing effect for purulent wounds.

Summary: We demonstrate a polar phase in the columnar perovskite (NaY)MnMnTi4O12, resulting from cation ordering on A site columns, which are oppositely displaced through coupling to B site octahedral tilts. This ordering, controlled by annealing temperature, also polarizes the local dipoles associated with pseudo-Jahn-Teller active Mn2+ ions, generating an additional ferroelectric order. Below T-N approximately 12 K, Mn2+ spins order, making this system rare in having ordered electric and magnetic dipoles on the same transition metal sublattice.

Summary: Electrodynamic therapy (EDT) is an emerging alternative approach for tumor treatment, based on the electrocatalytic activation of water dissociation on platinum nanoparticles (PtNPs) to produce hydroxyl radicals. However, the mechanism of EDT remains controversial, particularly when PtNPs are not in direct contact with electrodes. This study reveals the fundamental mechanism of EDT, identifying the crucial reactant as free chlorine generated during electrolysis. Experimental examinations and calculations confirm the catalytic activation of HOCl by PtNPs, resulting in the production of oxygen anion radicals and the corrosion of PtNPs. Cytotoxicity and intracellular abnormalities further support these findings, offering new insight into the in vitro anti-cancer mechanism of EDT.
