Summary: In this study, strontium ferrite nanofibers with different Sr:Fe ratios were fabricated using electrospinning and annealing. The crystal structures and magnetic properties of the nanofibers were analyzed through microscopy and X-ray diffraction. It was found that the nanofibers with Sr:Fe ratios of 1:1, 1:2, and 1:12 possessed tetragonal SrFeO2.86, orthorhombic SrFe2O4, and hexagonal SrFe12O19 structures, respectively. Hysteresis loop measurements showed slight variations in saturation magnetization (Ms) and residual magnetization (Mr) among the nanofibers. This study clarifies the crystal structure of strontium ferrite nanofibers and provides a potential candidate for permanent magnet applications.

Summary: Nanocomposites of graphene quantum dots modified gadolinium oxide particles were synthesized and the effects of graphene quantum dots amount and gadolinium oxide particle size on the properties of nanocomposites were investigated. The synthesized particles exhibited excellent fluorescence and magnetic properties, and the fluorescence property could be optimized by varying the ratio of graphene quantum dots to gadolinium oxide. Additionally, the relaxation property of the nanocomposites was improved by the larger gadolinium oxide particles. Therefore, these nanocomposites with magnetic and fluorescence characteristics have potential applications in biological imaging, drug targeting, and in-vivo diagnostic analysis.

Summary: One of the key challenges in the development of iron-oxide-based magnetic nanoparticles is their long-term physical stability. This study introduces electrospinning as a drying method for ethanol-based and water-based MNP dispersions, resulting in high-loaded dry MNP products. The use of polymers in the nanofibers improves the stability of the MNPs in high ionic strength dispersion medium. The dry product in the form of a nanofiber mat prevents aerosolization and unintentional exposure.

Summary: In this study, Li1.2Mn0.54Ni0.13Co0.13O2 nanorods, a cathode material for lithium-ion batteries, were prepared using a self-template method, with rod-like Mn2O3 as templates. The effect of calcination temperature on the morphology and electrochemical properties of the electrode materials was investigated. The Li1.2Mn0.54Ni0.13Co0.13O2 nanorods exhibited a high initial capacity and capacity retention rate, attributed to the enhanced structural stability, lower charge transfer resistance, and shorter lithium-ion transport pathway.

Summary: In this study, the concept of a light stimulus response-enhanced anisotropic conductive Janus membrane (L-ACJM) was proposed for the first time, introducing a new strategy of combining photoconduction with anisotropic conduction to improve material anisotropic conductivity. The L-ACJM was prepared with a top-bottom structure using Janus nanobelts and nanofibers. It exhibited enhanced anisotropic conductivity and dual-mode luminescence under light irradiation. The photoconductive effect of DF allowed for the modulation of conductivity and anisotropy by light. This research provides theoretical and technical support for the development of new anisotropic conductive films and multifunctional nanostructured materials.
