Cellulose acetate butyrate/cellulose Janus nanofiber membrane for unidirectional moisture conduction at Salimpour Site.

Finding a green approach for silver nanoparticle (AgNP) synthesis and as an adsorbent for safe contaminant removal in water has become a challenge. In this study, AgNP were green synthesised into a biopolymer matrix (natural rubber latex/polyvinyl alcohol (PVA/NRL)) via electrospinning. Efficiency of the synthesised nanofibre composites in removing mercury (Hg) from an aqueous solution was examined. SEM and TEM analysis showed that AgNP were more visible on the fibre’s surface at a lower concentration (0.01 M AgNP), whilst at a higher concentration (0.015 M AgNP), relatively more AgNP were found within the fibre. The average sizes of the AgNP were relatively larger (8.15 ± 0.09 nm) in 0. 2023-11-01

Nanoscale optical fibers, capable of confining light at the nanoscale, exhibit nonlinear effects and generate a strong evanescent field interacting with the surrounding environment. In this study, we compared various nanofibers composed of different glasses, closely matching the refractive index of silica, while immersed in acetone. Our objective was to optimize the Kerr effect contributions from either the core or the cladding, dependent on factors such as nanofiber dimensions, core optical properties, and the effective area of the fundamental mode HE11 both inside and outside the nanofiber core. Our findings reveal that the fluorophosphate (S-FPM3) nanofiber exhibits a dominant Kerr 2024-02-01

Wound management is a complex clinical challenge that needs advanced materials and techniques for satisfactory results. Electrospun nanofiber mats have emerged as an innovative alternative for wound healing purposes due to their porous architecture, greater surface area, ease of water absorption, mimicry of the extracellular matrix of natural tissues and tunable mechanical properties. This paper sheds light on recent advances in the fabrication techniques, properties, structural features and application of electrospun polymeric nanofiber mats for wound healing purposes emphasizing the importance of polymer selection and processing parameters in tailoring their physicochemical properties. 2024-12-01

Purpose As a result of referee evaluation, the subject scope of the article has been expanded. Previously, only polycaprolactone (PCL) loaded with peppermint extract had been studied. As a result of peer review, nanostructure production was made with peppermint-loaded polylactic acid (PLA). Literature information about PLA polymer has been added to the Introduction section. Additionally, to analyze the presence of peppermint extract in Fourier transform infrared (FTIR) measurements, a comparison was made with 100% PCL, 100% PLA and 100% peppermint extract. In order to observe the effect of polymer type, evaluations were made between the produced peppermint-loaded nanostructures containing 2024-12-01

Antibacterial materials are increasingly significant, particularly for biomaterials and food packaging applications. Materials with good elasticity and antibacterial properties are crucial in this line of work. This study focused on the investigation of nanofiber properties in elasticity and antibacterial by combining Moringa oleifera (MO) zinc oxide nanoparticles (ZnO NPs) with polyvinyl alcohol (PVA) nanofiber. The PVA/MO/ZnO nanofiber is fabricated using the electrospinning method. The morphology of PVA/MO/ZnO nanofiber shows smooth and uniform fibers with 292 nm in diameter size. The EDX mapping also demonstrates the successful loading of ZnO NPs into fibers, 2024-12-01
