Summary: Cellulose acetate (CA) nanofibers were prepared using solution blow co-spinning (SBS) with poly(ethylene oxide) (PEO), and pure CA membranes were obtained by washing water-soluble PEO from the fibrous CA-PEO blend. The nanofibrous membranes were characterized using various methods, including optical and scanning electron microscopy, differential scanning calorimetry, infrared spectroscopy, and surface zeta potential measurements. The study confirmed the removal of PEO and the successful deacetylation to cellulose, and also proposed a new staining method for differentiating CA and PEO components.

Summary: Innovation of photocatalysts with acceptable performance and easy recyclability through magnetic separation is a crucial challenge for researchers, as these materials have the potential to improve environmental health. Fe2O3 nanostructures were effectively loaded onto ZnS/ZnIn2S4 nanocomposites via a glycothermal process. The study investigated the impact of the amount of Fe2O3 nanostructures on the structural, physical, magnetic, and photocatalytic properties of the resulting nanocomposites. The magnetic recyclable photocatalysts exhibited a flower-shaped microstructure assembled from nanosheets. The ZnS/ZnIn2S4/Fe2O3 nanocomposites showed higher saturation magnetization than the binary ZnS/ZnIn2S4 nanocomposites. Photocatalytic decolorization experiments demonstrated high removal efficiencies for Rhodamine B and Methyl orange solutions using the ZnS/ZnIn2S4/Fe2O3 nanocomposites. Additionally, the nanocomposites could be easily separated and recycled multiple times with a degradation efficiency of 60.83%. The magnetic ZnS/ZnIn2S4/Fe2O3 nanocomposites are suitable for large-scale applications in industrial water treatment systems.

Summary: In this study, an ErMnO3/ErMn2O5/CuO/g-C3N4 nanocomposite was synthesized and used for H2 storage. The nanocomposite was prepared through in-situ synthesis of ErMnO3/ErMn2O5/CuO (NC-1), followed by the addition of g-C3N4 to prepare ErMnO3/ErMn2O5/CuO/g-C3N4 nanocomposite (NC-2). The presence of CuO did not affect the optical property of ErMnO3/ErMn2O5, while the addition of g-C3N4 increased the band gap due to particle agglomeration on ErMnO3. The magnetic properties varied in each step, with ErMnO3 exhibiting ferromagnetic behavior that changed to paramagnetic in NC-1, and ferromagnetism behavior in NC-2. Furthermore, CuO and g-C3N4 were found to enhance the H2 storage capacity of ErMnO3/ErMn2O5.

Summary: Thulium vanadate (TmVO4) nanorods were synthesized using Schiff-base ligands through a sonochemical method, and they exhibited promising photocatalytic activity. The crystal structure and morphology of TmVO4 were optimized by varying the Schiff-base ligands, H2Salen molar ratio, sonication time and power, and calcination time. The specific surface area was determined to be 24.91 m2/g, and the bandgap was found to be 2.3 eV, indicating its potential for visible light photocatalytic applications. The highest efficiency of 97.7% was achieved under visible light when 45 mg TmVO4 nanocatalysts were present in 10 ppm Eriochorome Black T solution at pH = 10.

Summary: This study focuses on the hydrogen storage ability of sol-gel synthesized Ce2Y2O7 nanoribbons as active materials. The impact of different carbonous materials (such as graphene oxide, nitrogen-doped graphene quantum dots, and g-C3N4) on the hydrogen storage capacity of Ce2Y2O7 nanoribbons was compared. The carbonous nanocomposites provided were characterized using various methods to identify their phase purity, shape, and porosity. Galvanostatic charge-discharge profiles were performed for all samples to achieve optimal capacitance. The results showed that the nanocomposites of GO/Ce2Y2O7, N-GQDs/Ce2Y2O7, and g-C3N4/Ce2Y2O7 had maximum discharge capacities of 656, 686, and 757 mAhg(-1), respectively, while pristine Ce2Y2O7 nanoribbons had a discharge capacity of 643 mAhg(-1) after 15 cycles.

Summary: Electrode materials for electrochemical hydrogen storage (EHS) were synthesized using the sol-gel process with PrCoO3 Perovskite, CuO, and Graphitic carbon nitride. Flower-like structures with PrCoO3 nanoparticles on scaly-shaped CuO on g-C3N4 nanosheets were observed by SEM. The effect of natural fuel and maleic acid on the synthesis of PrCoO3 was compared. X-ray diffraction showed pure phase of PrCoO3 at 700 degrees C, but impurity phases were present at 600 and 800 degrees C. PrCoO3/CuO/g-C3N4 exhibited higher hydrogen storage capacity compared to pristine PrCoO3. The improved performance suggests the potential application of PrCoO3/CuO/g-C3N4 in electrochemical hydrogen storage.
