Summary: The study predicts new trigonal YOBr and monolayered crystals with ultrawide bandgaps and exceptional properties through ab initio simulations. The YOBr crystal undergoes a structural transformation under hydrostatic pressure, accompanied by an indirect-direct band transition. Monolayers of metal oxyhalides MOX have potential applications in UV-electronics and photocatalysis due to remarkable ultraviolet light absorption and appreciable band edges, offering promising ultrawide-bandgap semiconductors for future optoelectronic devices.

Summary: For photonic devices, disorder and complexity have traditionally been seen as unwanted features. However, this review shows that disorder can actually be harnessed to enable unique functionalities in photonic devices. Disordered systems offer more possibilities and diverse optical responses compared to ordered systems. They have been used for secret key generation, random projection, matrix multiplication, and reservoir computing. Disordered photonic devices can function as multiple optical components and have been employed in hyperspectral imaging, polarimetry, and pulse measurement. Incorporating disorder into devices also allows for speckle-free imaging, broad tunability, and suppression of instabilities.

Summary: Metal halide perovskite scintillators have high quantum yields and great potential in indirect ionizing radiation detection. However, the afterglow phenomenon limits their fast development. A new type of hybrid X-ray detector wafer, combining direct methylamine lead iodide (MAPbI(3)) semiconductor and indirect cesium copper iodide (Cs3Cu2I5) scintillator, reduces the device response time to X-rays and improves the detection capability. The hybrid wafer also demonstrates improved operation stability.

Summary: Permeates generated in the dairy industry can now be recognized as potential ingredients or raw materials for value-added products, instead of being treated as waste or used in animal feed. They can be directly added to different food products or used in the production of prebiotic drinks or sports beverages. However, challenges such as impurities, short shelf life, and handling difficulties need to be addressed. Economic feasibility and further research on each application are still necessary.

Summary: Single crystal halide perovskites with microscale dimensions are a promising material for developing microlasers due to their defect tolerance and broad tunability of luminescence. Femtosecond laser irradiation of CsPbBr3 allows for precise and ultraclean ablation controlled at subwavelength scale. The unique properties of perovskites, such as low thermal conductivity and high refractive index, enable high spatial resolution and direct imprinting of incident laser fields for creating micro-lens and light-emitting metasurfaces.

Summary: In this paper, the structural formability, electronic, optical, and thermoelectric properties of Ba2XSbO6 (X = Al, Ga) double perovskite oxides were studied using density functional theory (DFT). The calculations indicated that both Ba2AlSbO6 and Ba2GaSbO6 showed perfect cubic structures with promising properties for water splitting, as they were found to be semiconductors with direct bandgaps and exhibited good absorption coefficients in the visible spectrum. Additionally, the study revealed that hydrostatic pressure could enhance the bandgap of the materials without altering their direct bandgap nature. Moreover, Ba2AlSbO6 and Ba2GaSbO6 were identified as promising thermoelectric materials due to their good Seebeck coefficients and thermoelectric power factors. Overall, the double perovskite materials showed potential for various electronic, optical, and thermoelectric applications, particularly in new energy production.

Summary: Green phosphorus and its monolayer variant, GreenP, are new members of 2D phosphorus polymorphs with high stability, tunable bandgap, excellent electronic transport, and anisotropic properties. Gas-sensing characteristics show stronger adsorption of NO, NO2, CO, and CO2 on GreenP, while NH3 and H2O are weakly physisorbed. Sulfur doping can enhance NO2 adsorption, leading to increased sensitivity in sensing devices.

Summary: This study reports the use of titanium carbide MXenes as cathode additives to suppress the shuttle effect in room-temperature sodium sulfur batteries. The findings show that the immense chemical bonding between Na2Sn and titanium carbide MXenes competes with the binding magnitudes of Na2Sn-electrolyte interaction, effectively resolving the shuttle phenomenon. The presence of titanium carbide MXenes also preserves the metallicity during the redox process and reduces the dissociation barrier of the final redox product, resulting in efficient utilization of sulfur.

Summary: The study investigates the colossal permittivity (CP) properties of (Tb3+/4++Sb5+) co-doped TiO2 (TSTO) ceramics. The findings reveal the extremely high dielectric constant, low loss tangent, and temperature stability of the TSTO ceramics. The presence of grains, grain boundaries, and microwave dielectric phases in the TSTO ceramic determines its dielectric behavior. The study also explains the appearance of semiconducting grains induced by Ti3+ via X-ray photoelectron spectroscopy.
