Summary: The study investigates the synthesis of zinc oxide nanostructures grown in situ on graphene oxide sheets using a solvothermal method with simultaneous reduction of the graphene oxide. It was found that the morphology of the zinc oxide particles is dependent on the precursor, while the particle size decreases with lower NaOH concentration and higher concentration of the GO suspension. Additionally, zinc oxide composites with higher amounts of GO suspension exhibit a lower band gap and higher specific surface area.

Summary: This study focuses on finding suitable polymers for the preparation of solid-like chloroaluminate-based electrolytes. By studying the solubility and gelling ability of different polymers in a deep eutectic solvent, with subsequent characterization of the electrochemical activity of the resulting gels, it was found that only poly(?-caprolactone) and poly(dimethyl siloxane) are soluble and produce gel electrolytes with AlCl3:urea. PDMS is shown to be as efficient as PEO in producing ionogels at low polymer concentrations.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
