Summary: Reusable face masks are a cost-effective alternative to disposable and surgical face masks during pandemics. This study demonstrates the development of self-cleaning fibers by incorporating a photocatalyst onto silicone-based fibrous membranes. The functionalized fibers exhibit degradation of photo-sensitive dye, antibacterial properties, as well as good air permeability and filtration efficiency.

Summary: Smooth, continuous, bead-free zinc oxide (ZnO)-loaded electrospun poly(vinyl alcohol) (PVA) nanofibers were successfully fabricated by adjusting PVA concentration and adding ZnO powders. Various analyses confirmed the successful physical blending of ZnO in PVA, and the optical bandgap of the ZnO:PVA composite sheets was found to be suitable for photocatalytic applications.

Summary: Pristine ZnO and iron-doped ZnO nanoparticles were prepared by precipitation route. The chemical structure of the samples was analyzed using thermogravimetric analysis, EDX, and XPS. The results showed that the iron-doped ZnO nanoparticles had a hexagonal structure, with increasing Fe content leading to higher lattice strain and smaller crystallite size. UV-vis absorption spectroscopy revealed a decrease in energy gap with increasing Fe content. Photoluminescence spectrometry indicated the presence of numerous recombination faults and sites. Magnetization measurements demonstrated ferromagnetism in the Fe-doped ZnO nanoparticles. These findings have important implications for the use of iron-doped ZnO nanoparticles in optoelectronic and spintronic applications.

Summary: In recent years, researchers have been interested in investigating the effect of nanoparticles with different morphologies in therapeutic applications. This study examines the effect of adding zinc oxide nanoparticles with a new morphology on the properties of PVA/CS nanofibers as a wound dressing. The results show that zinc oxide nanoparticles with pyramidal rod morphology increase the mechanical strength of the nanofibers, while star-like zinc oxide nanoparticles decrease the strength. Furthermore, incorporating zinc oxide nanoparticles enhances heat resistance, antibacterial activity, and wound healing. Therefore, PVA/CS nanofibers containing zinc oxide nanoparticles with pyramidal rod morphology have great potential in wound healing.

Summary: In this study, zinc oxide nanoparticles were bonded to a polyurethane/polysulfone electrospun nanofiber membrane and modified with Hexadecyltrimethoxysilane to create a waterproof and moisture permeable composite nanofiber membrane with excellent UV resistance. The optimal PU/PSF mass ratio of 7:3 resulted in the best fiber morphology, thermal stability, waterproof, and moisture permeability properties. The treated composite film showed a contact angle of 149 degrees, moisture permeability of 9.6 kg/m2/d, and a UPF value up to 1117.67, demonstrating outstanding UV resistance.

Summary: Electrospun carbon nanofibers (CNFs) have been studied for their potential in tissue engineering. This study investigated the effects of zinc oxide nanoparticles (ZnONPs) on the properties of CNF meshes. The results showed that the presence of ZnONPs improved the wettability and structure formation of CNFs, while decreasing their conductivity. In addition, the ZnONP-CNFs were found to be biocompatible and suitable for bone tissue engineering.

Summary: Forming composite nanofibers of terbium oxide (Tb2O3) and zinc oxide (ZnO) through electrospinning and annealing resulted in a gas sensor with excellent sensing performance for nitric oxide (NO) gas. The Tb2O3/ZnO composite nanofiber exhibited a high response to 1 ppm NO gas at 180 degrees C, with low response to other interference gases. The sensor also showed good repeatability and long-term stability, indicating the promising potential of ZnO for real applications.

Summary: Non-woven fibers containing cerium and zinc titanates were prepared using sol-gel and electrospinning methods. The fibers were characterized by various techniques and the results showed the presence of ceria fluorite nanocrystals and zinc oxide wurtzite phase at different temperatures. The nanofibers exhibited an increase in ceria nanocrystallite size with increasing calcination temperature, while the BET specific surface area decreased with higher temperatures. These fibers have potential applications in photocatalysis.

Summary: The synthesis of radial ZnO mesocrystals consisting of tapered ZnO nanowires is investigated, and the formation mechanism is elucidated. The results reveal that the formation of radial ZnO mesocrystals starts with the generation of ZnO nuclei inside an amorphous Zn(OH)2 phase, followed by preferential growth of ZnO nanowires and self-assembling of the nanowires to form the mesocrystals.

Summary: This study optimized the synthesis parameters of nanosized zinc oxide using the electrospinning technique. The effects of applied voltage, tip-to-collector distance, and annealing temperature on the particle size of zinc oxide were investigated. The results suggest that precise control of size and morphology of nanosized zinc oxide can be achieved by varying electrospinning conditions, precursor solution concentration, and sintering temperature.

Summary: This study aimed to design bifunctional electrospun membranes based on polylactic acid (PLA) with the incorporation of black phosphorus nanosheets (BPNS) and nano-zinc oxide (nZnO) particles for enhanced bioactivity and antibacterial features. The optimal spinning process was determined, and the mechanical properties of the PLA membranes were improved by increasing PLA concentration and decreasing spinning solution and drum rotation speeds. The composite membranes exhibited remarkable photothermal therapy capabilities and an improved inhibitory effect on both Escherichia coli and Staphylococcus aureus. The cytotoxicity and adhesion experiments also indicated good cyto-compatibility. Overall, the utilization of BPNS and n-ZnO fillers in PLA-based membranes showed great potential for interventional catheter materials.

Summary: In this study, Nb5+ and In3+ ions were used as dopants in titanium/tungsten oxide nanostructures for humidity detection. The sensors showed a conduction transition from p- to n-type around 30-40% RH and exhibited better sensitivity to moisture compared to previous research. The impedance modulus variation was up to 1.1 and 1.3 orders of magnitude for the 4 wt % niobium and indium doped samples, respectively, which was attributed to the microstructure and alternative preparation process.
