Summary: The aim of this study was to develop a novel amikacin (AMI) delivery system with prolonged release. Composite electrospun nanofibers of PLA supplemented with AMI-loaded Si nanoparticles of different morphology were used. The physical properties of the resultant materials were characterized and the AMI content in the release study was determined. The results showed that the silica nanoparticles had a significant effect on the hydrophilic properties of the nanofiber surfaces and the AMI-loaded nanofibers exhibited enhanced antibacterial properties.

Summary: In this research, electrospun nanofibers were fabricated using functionalized porous graphene (FPG), modified SBA-15 (SBA/CuO), Polyvinylpyrrolidone (PVP), and Polyacrylonitrile (PAN). The nanofibers with the best morphology were obtained by optimizing FPG, SBA/CuO, and PAN concentrations, as well as applied voltage. A nano-filter was made from these nanofibers to remove water pollutants, and its performance was evaluated. The results showed high efficiency in removing dyes and metal ions from factory wastewater.

Summary: This study successfully fabricated mesoporous structured silica nanofibrous membranes (MPSNMs) with high flexibility, specific surface area, and mesopore volume, showing excellent adsorption capability and recyclability towards tetracycline antibiotics. The adsorption mechanism is likely a synergistic effect of hydrogen-bonding interactions and electrostatic attraction between tetracycline and MPSNMs.

Summary: Electrospinning has attracted attention for its ability to create nonwoven nanofiber webs with high surface area and porosity. However, traditional needle and syringe-based systems have limited productivity. This article examines the latest developments in nonconventional electrospinning methods, such as needleless and syringeless electrospinning, which have the potential to meet industrial-scale manufacturing requirements and produce nanofibers that are difficult to spin using traditional techniques.

Summary: This research aims to improve the electrospinnability of alginate by focusing on the effect of inter- and intramolecular hydrogen bonding, using Li+ cation to reduce the hydrogen bonding density. Viscosity, electrical conductivity, FTIR, and H-1 NMR measurements confirmed the lower intramolecular hydrogen bonding density in Li-Alg. SEM images demonstrated the enhanced electrospinnability of Li-Alg compared to Na-Alg and K-Alg salts.

Summary: One-dimensional core-sheath nanofibers consisting of platinum-loaded ceria sheath on mesoporous silica core were successfully synthesized and used as catalysts for the reverse water gas shift reaction. The core-sheath nanofibers had a core diameter of 100-300 nm and a sheath thickness of 40-100 nm with a Pt loading of 0.5 wt.%. The impregnated catalyst, Pt-CeO2 NF@mesoporous SiO2, showed the best catalytic performance with a CO2 conversion of 8.9% at 350 degrees C.
