Summary: The study shows that an interface between two identical metal/dielectric plane-layered ferromagnetic (meta)materials with different directions of magnetization can support electromagnetic surface waves in the visible or near-infrared band, exhibiting valve action and a unique TEM structure. Additionally, weak optical gyrotropy in a plane-layered metal/dielectric metamaterial can be significantly enhanced due to quasi-static LC resonance in the structure.

Summary: In this study, lead tungstate (PbWO4), nickel doped PbWO4 (Ni-PbWO4), and polyethylene glycol assisted Ni doped PbWO4 (Ni-PEG-PbWO4) nanoparticles were synthesized by the co-precipitation method. The nanoparticles were characterized using XRD, FTIR, UV-visible, and photoluminescence spectra. The BET surface area, SEM analysis, EDX, and XPS measurements were performed to confirm the characteristics of the nanoparticles. The Ni-PEG-PbWO4 nanoparticles showed superior photocatalytic activity against the hazardous dye methyl orange (MO) due to their smaller particle size and higher surface area. These nanoparticles have great potential for wastewater treatment and environmental cleanup.

Summary: In this study, 1-ethyl-3-methylimidazolium acetate ([EMIM]Ac) ionic liquid was introduced to passivate the surface defects of perovskite films, improving the performance and stability of metal halide perovskite solar cells. The carbonyl groups of [EMIM]Ac coordinate with the uncoordinated lead ions on the perovskite surface, reducing nonradiative recombination and improving working stability. The power conversion efficiency of the solar cell increased from 16.95% to 19.29% with [EMIM]Ac treatment. This surface passivation method using an ionic liquid may have significant implications for the development and practical application of perovskite solar cells.

Summary: Here, an in situ photoluminescence (PL) system was developed to monitor the nucleation and growth of perovskite nanocrystals and achieve highly confined and monodispersed quantum dots (QDs) with an average size of 3.4 nm. Pure-blue (460 nm wavelength) CsPbBr3 QDs with near unity PL quantum yield and a narrow size distribution (small size dispersion of 9.6%) were produced. Light-emitting diodes (LEDs) based on these QDs showed narrow electroluminescence with a full width at half-maximum of 20 nm and a high color purity of 97.3%. The LEDs also exhibited a high external quantum efficiency of 10.1%, maximum luminance of 11,610 cd m-2, and a continuous operation lifetime of 21 h at the initial luminance of 102 cd m-2, which represents the state-of-the-art for pure-blue perovskite LEDs.

Summary: Atomic-scale ferroelectrics with a layered structure of stabilized bismuth oxide film through samarium bondage have been developed. The thickness of the film can reach 1 nanometer and it can be grown on various substrates using a cost-effective chemical solution deposition method. The thin films exhibit standard ferroelectric hysteresis and relatively large remanent polarization. First-principles calculations confirm the structure and suggest that these films are lone pair-driven ferroelectric materials. The design of ultrathin ferroelectric films holds great potential for atomic-scale electronic devices manufacturing.

Summary: This paper introduces double perovskite ferroelectric thin films as a new material system with diverse composition and structure, providing new possibilities for the development of ferroelectric thin films. The ordered double perovskite ferroelectric thin films exhibit excellent ferroelectric, dielectric, magnetic, and optical properties, with potential applications in photovoltaic cells, information memory, and spintronic and photoelectric devices. However, complex internal physical mechanisms and difficult preparation conditions hinder its further development. This paper reviews the characterization methods and synthesis conditions affecting the ordering of double perovskite ferroelectrics, and presents the advances and challenges in various areas related to this material system.

Summary: The first measurement of ferroelectric hysteresis loop in pure anatase-phase titanium dioxide was reported, demonstrating ferroelectric-like behavior in a-TiO2 epitaxial thin films prepared by chemical solution deposition method. The quality of epitaxial films was confirmed by synchrotron based X-ray diffraction and reciprocal space mapping. The results showed that the polarization of a-TiO2 film with a thickness of 14.5 nm could reach approximately 0.42 mu C/cm2. Atomic force microscopy (PFM) revealed ferroelectric-like behavior in the 7.5 nm a-TiO2 film, with the PFM polarization switch maintained for over 100 minutes. The origin of this behavior is attributed to strain and vacancy-induced distortion, while the electrochemical effect has a significant influence on the intrinsic ferroelectric performance.

Summary: Polarization and optical properties of BiFeO3-based ferroelectric films are regulated by both chemical composition and interlayer design. The improvement of ferroelectricity and bandgap is achieved through these methods. The remanent polarization is enhanced from 0.2 mu C/cm2 to 73.8 mu C/cm2 and the band gap is reduced from 2.42 eV to 2.23 eV. The optimal films show improved polarization and band gap, with a short-circuit current density of 89.0 nA and open circuit voltage of 0.412 V.

First-principles calculations confirmed the film's structure and suggested it to be a lone pair-driven ferroelectric material.
